A strong lawn mower hydraulic pump replacement matches the mower’s original part number and transmission, which makes Leyuncot Hydraulic Pump a leading choice for specified Toro Z Master and Exmark models. This lineup includes complete replacement pumps for several mower families as well as a Hydro-Gear charge pump kit intended to address oil leakage. The key distinction is fit: a pump for a Toro Z500 is not automatically right for an Exmark Lazer Z, even when the products look similar.
Use the listed replacement numbers and compatible models as a starting point, then verify your mower’s model, year, deck, and existing pump number before ordering. The products below cover several commonly listed BDP-10A applications, plus more narrowly identified Scag and mower-specific replacements.
Leyuncot Hydraulic Pump is the best overall choice here because its listed replacement numbers include Toro 103-7262 and 116-2444, and its stated fit covers Toro Z Master Z500 mowers from 2004 onward with 60- and 72-inch decks, plus specified Exmark Lazer models. That breadth makes it a practical starting point for buyers whose mower matches those details. Check the pump’s existing part number and exact mower model before purchasing; other products in this list serve different BDP-10A or charge-pump applications.

Detailed Reviews: Best Hydraulic Pump For Lawn Mower
#1 · Best Overall
1. Leyuncot Hydraulic Pump
- Weight: 9.9 lb
- Dimensions: 4.4 x 3.6 x 4.9 in
Best for: Toro Z500 and Exmark owners.
Why it ranks #1: Lists Toro 103-7262 and 116-2444 replacements and specifies Z Master Z500 models from 2004 onward with 60- and 72-inch decks, plus Exmark Lazer fits.
Its cross-reference to Toro numbers 103-7262 and 116-2444 gives Z500 owners a direct way to identify this replacement pump. Leyuncot lists Toro Z Master Z500 models from 2004 onward with 60- or 72-inch decks, plus specified Exmark Lazer models, making model and part-number matching central to the choice.
The listed Toro Z500 application covers 2004-and-later machines with 60- and 72-inch decks, helping narrow the fit to those configurations rather than the whole Z Master range. Exmark Lazer Z AC/AS/LC and Lazer AS compatibility extends its stated coverage to select Exmark mowers. Cross-referenced numbers PK-BGAB-EY1X-XXXX, 103-7262, 116-2444, and PJ-BGAB-EY1X-XXXX provide concrete identifiers for checking a replacement against the existing pump before installation.
- Lists Toro replacement numbers 103-7262 and 116-2444
- Specifies Z500 models from 2004 onward
- Names 60- and 72-inch deck configurations
- Also lists Exmark Lazer Z AC/AS/LC and Lazer AS
- Its stated Toro fit is limited to specified Z500 years and deck sizes.
Skip it if you need a pump for another Toro series; NEWZQ's BDP-10A-427 listing covers several Lazer Z and Z Master configurations.
Toro Z500 owners with a 2004-or-newer mower and a 60- or 72-inch deck are the clearest match, as are owners of the listed Exmark Lazer models. Check the pump number and mower configuration before choosing.

2. NEWZQ Hydrostatic Pump
- Weight: 9.26 lb

Best for: Lazer Z deck-size matching.
Why it ranks #2: Covers Exmark Lazer Z serial 370,000 and newer with 52-, 60-, and 72-inch decks, and lists several Toro Z Master applications and replacement numbers.
Coverage for Lazer Z serial numbers 370,000 and newer, with 52-, 60-, and 72-inch decks, is the key fit detail for this NEWZQ replacement pump. Its cross-references include BDP-10A-433, BDP-10A-427, and Toro part numbers, helping owners compare several established identifiers.
The Lazer Z application is specified by serial number and deck size, which gives owners a practical way to narrow compatibility before starting a pump replacement. The listing also covers Toro Z 250's Z Master 742XX Series with 52-, 62-, and 72-inch decks, and Z500 Z Master models from 2004 onward with 60- and 72-inch decks. Cross-references including 103-2675, 103-1943, and PG-1GAB-DY1X-XXXX support checking the old part against the replacement listing.

3. Demfec Hydro Gear Pump
- Weight: 9.31 lb
- Dimensions: 9.88 x 7.91 x 7.8 in
Best for: BDP-10A multi-reference buyers.
Why it ranks #3: Lists BDP-10A-427 and 433 replacements and compatible Lazer Z and Toro Z Master deck ranges, providing useful fit details for common listed applications.
Multiple identifiers—including PG-1GAP-DY1X-XXX, PG-1GAB-DY1X-XXXX, and BDP-10A-427—make this Demfec pump easier to cross-check across parts references. Its stated applications cover selected Lazer Z and Toro Z Master configurations, including deck sizes that vary by mower series.
The compatibility list distinguishes Lazer Z serial numbers 370,000 and newer with 52-, 60-, and 72-inch decks from Toro Z 250's Z Master 742XX Series with 52-, 62-, and 72-inch decks. It also names Z500 Z Master models from 2004 onward with 60- and 72-inch decks. References such as Ariens 02964400, Toro 103-1943, Stens 025-007, and Hydro-Gear BDP-10A-433 give buyers several specific identifiers to compare before fitting.

4. Exmark 103-2675 Pump
- Dimensions: 8 x 7 x 6 in
Best for: Exmark Lazer Z pump match.
Why it ranks #4: Names Exmark Lazer Z AC, AS, and LC models with 52-, 60-, and 72-inch sizes, and identifies replacement number 103-1943.
The Exmark 103-2675 identifier is the clearest starting point for matching this hydraulic pump to a Lazer Z AC, AS, or LC mower. Its listed deck applications are 52, 60, and 72 inches, with 103-1943 also provided as a cross-reference for parts lookup.
Exmark names Lazer Z AC, AS, and LC models, giving owners a defined mower family to check rather than a general hydraulic-pump application. The 52-, 60-, and 72-inch deck sizes add another fit checkpoint, while model number 103-2675 and cross-reference 103-1943 help compare the listing with existing parts information. Its 8-by-7-by-6-inch dimensions can support space planning during replacement preparation, but the supplied fit details remain specific to the listed Exmark applications.
- Identifies Exmark part number 103-2675
- Lists Lazer Z AC, AS, and LC compatibility
- Names 52-, 60-, and 72-inch decks
- Provides 8-by-7-by-6-inch product dimensions

Exmark Lazer Z AC, AS, and LC owners with a listed 52-, 60-, or 72-inch deck are the intended buyers. Use 103-2675 or 103-1943 to check the part reference, and keep the stated mower-family boundary in mind.

5. Hydro-Gear PG-1GCC Pump
Best for: Scag Wildcat and Tiger Cub.
Why it ranks #5: Identified as a genuine Hydro-Gear part and specifies compatibility with Scag Wildcat and Tiger Cub mowers, including part number 482644.
A genuine Hydro-Gear PG-1GCC-DY1X-XXXX RH hydraulic pump is the defining detail here, with Scag 482644 and BDP-10A-419 references identifying its intended replacement application. The listing names Scag Wildcat and Tiger Cub mowers, giving owners of those machines a focused OEM-branded option to consider.
The stated Scag Wildcat and Tiger Cub compatibility gives this pump a narrower application than a general BDP-10A listing, so model identification matters before purchase. Its 482644 and BDP-10A-419 references provide additional ways to compare the installed pump or parts record. Hydro-Gear identifies it as a genuine RH pump, and the listed 1.5-inch inlet and outlet connection sizes are useful specifications to check against the hydraulic setup during replacement planning.
- Genuine Hydro-Gear PG-1GCC-DY1X-XXXX pump
- Identifies the pump as RH
- Lists Scag Wildcat and Tiger Cub compatibility
- Provides 482644 and BDP-10A-419 references
- Its stated mower fit is limited to Scag Wildcat and Tiger Cub applications.

Scag Wildcat and Tiger Cub owners looking for the listed genuine RH Hydro-Gear pump are the intended buyers. Treat the model and reference-number match as essential, and check the stated 1.5-inch connections against the replacement job.

6. MujaUdg Toro Replacement Pump
- Weight: 9.48 lb
- Dimensions: 5.5 x 5.5 x 7.87 in
Best for: Toro Z500 pump replacement.
Why it ranks #6: Specifies Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks, plus Exmark Lazer AS and Lazer Z AC, AS, and LC models.
The stated no-modification fit to existing hydraulic lines is a practical differentiator for this Toro Z500 replacement pump. MujaUdg lists Z Master models from 2004 onward with 60- and 72-inch decks, as well as specified Exmark Lazer models, focusing its compatibility on a defined set of zero-turn mowers.
Factory pump-specification matching and the stated fit without modifying existing hydraulic lines speak directly to replacement planning for the listed Toro models. Compatibility covers Z Master Z500 machines from 2004 onward with 60- or 72-inch cutting decks, which helps owners screen by both series and configuration. The listing also names Exmark Lazer AS and Lazer Z AC/AS/LC models, so owners of those mowers can assess the same replacement, subject to matching their pump application.
- States fit without modifications to existing hydraulic lines
- Lists Toro Z Master Z500 from 2004 onward
- Specifies 60- and 72-inch cutting decks
- Includes Exmark Lazer AS and Lazer Z AC/AS/LC
- Its stated Toro compatibility is limited to Z500 models and specified deck sizes.
Skip it if you need the listed Scag Wildcat or Tiger Cub RH pump; Hydro-Gear's PG-1GCC-DY1X-XXXX is the model-specific alternative.
Toro Z500 owners with a 2004-or-newer machine and a 60- or 72-inch deck are the primary fit, along with owners of the listed Exmark Lazer models. Confirm the mower and pump application even with the line-fit claim.

7. YUVANT Gear Pump
- Weight: 9.15 lb
Best for: Exmark Lazer Z HP owners.
Why it ranks #7: Lists Hydro-Gear BDP-10A-414 and replacement numbers for Gravely and Exmark, with fit for a 52-inch Z Master and Exmark Lazer Z HP.
The PG-1GNP-DY1X-XXXX reference ties this YUVANT gear pump to Hydro Gear BDP-10A-414 and Exmark 103-1942 applications. Its listed fit for Exmark Lazer Z HP and the 74179 Z Master 52-inch SFS side-discharge mower makes it useful for buyers matching a specific part number and machine.
The compatibility list centers on Exmark Lazer Z HP and 74179 Z Master 52-inch SFS side-discharge deck mowers, giving owners concrete model details to compare before replacement. Cross-references to Exmark 103-1942, Gravely 21545200, and Hydro Gear BDP-10A-414 make the pump easier to identify when parts records use different numbers. The package dimensions and 9.15-pound weight may also help with handling and space planning while preparing for the replacement.
- References Exmark 103-1942
- Lists Hydro Gear BDP-10A-414

Owners of an Exmark Lazer Z HP or the specified 74179 Z Master 52-inch SFS mower are the clearest candidates. Match the listed number to the installed pump, since the stated fit is model-specific rather than a general mower application.

8. RONGPAS Hydraulic Gear Pump
- Weight: 9.28 lb
Best for: BDP-10A cross-reference shoppers.
Why it ranks #8: Lists BDP-10A-440 and multiple replacement numbers, with a stated fit for Husqvarna ZT 200 Series and several Bunton, Bobcat, and Ryan models.
Its BDP-10A-440 reference links this hydraulic gear pump to a named Hydro Gear series and several mower-part numbers. That makes it a candidate for owners tracing a replacement through OEM references, including listed Husqvarna ZT 200 Series applications, provided the exact pump and mower identifiers agree.
RONGPAS identifies the pump as PG-1HCA-DY1X-XXXX and gives BDP-10A-440 as a replacement reference, which can help when the existing component or parts record uses either designation. The application list also names Husqvarna ZT 200 Series mowers and Hydro Gear BDP-10A Series units, alongside references for Bobcat, Gravely, and other equipment. Because the compatibility list spans multiple brands and part numbers, checking the OEM number and mower model/year is important before installation.
- Identifies PG-1HCA-DY1X-XXXX
- References Hydro Gear BDP-10A-440
- Lists Husqvarna ZT 200 Series compatibility
- Includes Bobcat, Gravely, and other cross-references
- Fit depends on matching a specific BDP-10A reference and mower application.
Skip it if you have a Scag Wildcat or Tiger Cub needing the listed genuine RH pump; Hydro-Gear's PG-1GCC-DY1X-XXXX names those models.
This pump suits owners who can match PG-1HCA-DY1X-XXXX or BDP-10A-440 to a listed application, especially Husqvarna ZT 200 Series equipment. Confirm the mower model, year, and OEM number before committing to installation.

9. TEKKOAUTO Hydraulic Pump
- Weight: 9.48 lb
- Dimensions: 10.04 x 7.87 x 7.68 in
Best for: BDP-10A-316 cross-reference.
Why it ranks #9: Provides several reference numbers, including BDP-10A-316 and PG-1KCC-DY1X-XXXX, but describes compatibility only generally as BDP-10A Series.
Its broad set of OEM references, led by BDP-10A-316 and PG-1KCC-DY1X-XXXX, helps identify this TEKKOAUTO replacement across different parts records. The stated application is the mower BDP-10A Series, so the central buying task is confirming that series and matching one of the listed numbers.
The BDP-10A Series application establishes the compatibility scope, while references such as BDP-10A-316, BDP-10A-390, PG-1KCC-DY1X-XXXX, and PE-1KCC-DY1X-XXXX help owners compare their existing pump documentation. Additional numbers—including 2964300, 539127611, 482643, and 025-031—extend those cross-checks across the supplied parts references. At 10.04 by 7.87 by 7.68 inches and 9.48 pounds, its listed dimensions and weight can inform handling and replacement preparation.
- Lists BDP-10A-316 and BDP-10A-390 references
- Includes PG-1KCC-DY1X-XXXX and PE-1KCC-DY1X-XXXX
- States compatibility with mower BDP-10A Series
- Provides dimensions and item weight for handling planning
- Its stated application is limited to the mower BDP-10A Series.
Skip it if you need a specifically listed Toro Z500, Lazer Z, or Z 250's fit; NEWZQ's BDP-10A-427 listing names those configurations.
Owners replacing a pump in the mower BDP-10A Series are the intended buyers, particularly those who can match one of the listed OEM references. Confirm the series and number first; the supplied fit information does not identify particular mower models.

10. sixcow Charge Pump Kit
- Weight: 1.01 lb
- Dimensions: 4.5 x 3 x 1.15 in
Best for: Hydro-Gear charge-pump repair.
Why it ranks #10: This is a charge pump kit rather than a complete mower pump replacement; its listed fit covers Hydro-Gear ZT2800, ZT3100, ZT3400, and G700 transmissions.
This 72274 charge-pump kit specifically targets transmission oil leaks, giving owners of listed Hydro-Gear transmissions a repair-focused replacement option. Its stated compatibility includes ZT2800, ZT3100, ZT3400, and G700 series units, while multiple OE references help identify the intended part across Hydro-Gear and Scag applications.
The kit is listed for ZT2800, ZT3100, ZT3400, and G700 series hydraulic transmissions, so matching the transmission series is the key first step. Cross-references to Hydro-Gear 72274 and 71411, plus Scag HG71411, HG72274, and PXHG72274, help connect the replacement to different parts listings. Its stated purpose is addressing transmission oil leaks and supporting the functionality of the hydro pump, transaxle, or Hydro-Gear transmission.
- Targets transmission oil-leak repair
- Lists ZT2800, ZT3100, ZT3400, and G700 transmissions
- References Hydro-Gear 72274 and 71411
- Includes Scag HG71411, HG72274, and PXHG72274 references
- It is a charge-pump kit, not a complete hydraulic transmission.
Skip it if you need a complete mower pump rather than a charge-pump leak repair; Hydro-Gear's PG-1GCC-DY1X-XXXX is a listed replacement pump.
Choose this kit when the repair is for a compatible Hydro-Gear charge pump and transmission oil leakage, and verify the transmission series and OE reference first. It is not the right choice when a complete pump replacement is needed.

Why a leaking transmission may need a charge pump kit
A charge pump kit is not interchangeable with a complete hydraulic pump, so identify the failed component before choosing one. The sixcow kit is specifically described as a Hydro-Gear 72274 charge pump kit for ZT2800, ZT3100, ZT3400, and G700 transmissions, and its listing says it is designed to address transmission oil leaks. The other products here are presented as replacement hydraulic or gear pumps, generally with mower or pump part-number fit details.
Treating those product types as equivalent can lead to ordering a part that does not address the fault. A leak alone does not establish which component has failed, and the supplied product information does not diagnose a mower’s symptoms.
Confirm the transmission model and the required replacement number against the mower or transmission documentation before selecting the charge pump kit or a complete pump.
The compatibility trap: matching a number is not enough
A familiar replacement number is useful, but the listed model, deck, and serial details still matter. For example, NEWZQ names Exmark Lazer Z serial number 370,000 and newer and gives 52-, 60-, and 72-inch deck sizes; its Toro references cover specified Z Master series and deck sizes. Leyuncot instead specifies Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks, alongside particular Exmark Lazer models.
Those overlapping names do not establish universal interchangeability. Also compare the number on the installed pump with every replacement number in the listing: several products list multiple, distinct BDP-10A or OEM references.
If the mower’s model, year, serial range, or deck does not match the stated fit, seek confirmation before ordering rather than inferring compatibility from appearance or brand alone.
How to Choose a Lawn Mower Hydraulic Pump
Match the mower model and deck
Look for an explicit match to your mower model, year or serial range, and deck size. Leyuncot lists Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks; NEWZQ lists Exmark Lazer Z serial 370,000 and newer with 52-, 60-, and 72-inch decks. Demfec also lists Toro Z Master applications with 52-, 62-, and 72-inch decks.
These ranges are not universal fit claims: they distinguish particular applications. A buyer with a mower that matches a listed model and deck can use those details to narrow the choice, while someone with a different deck or model should prioritize a listing that explicitly names that configuration and confirm fit before ordering.
Check the replacement part numbers
Choose a pump whose listed replacement numbers match the number on your existing unit or the mower’s parts documentation. The products list different references: Leyuncot names 103-7262 and 116-2444; NEWZQ lists BDP-10A-427, BDP-10A-433, and 103-2675; YUVANT lists BDP-10A-414 and 103-Demfec also names BDP-10A-427 and 433, while TEKKOAUTO lists BDP-10A-316 and 390.
These numbers separate otherwise similar-looking listings into distinct applications. If your existing part number is clear, favor a listing that repeats it and also matches your mower.
If you have only a mower model, verify its correct pump number before selecting among overlapping product descriptions.
Choose the correct pump type and application
Determine whether the job calls for a complete replacement pump or a charge pump kit. Most listings here describe replacement hydraulic or gear pumps; sixcow is specifically a Hydro-Gear 72274 charge pump kit for ZT2800, ZT3100, ZT3400, and G700 transmissions, and is described as addressing oil leaks. Application also varies by mower family: Hydro-Gear PG-1GCC is listed for Scag Wildcat and Tiger Cub, while RONGPAS names Husqvarna ZT 200 Series and several Bunton, Bobcat, and Ryan applications.
A buyer with one of those specifically named machines should favor the corresponding fit; a buyer diagnosing leakage should first establish whether a charge pump kit is actually required rather than assuming every pump replacement is suitable.
Which hydraulic pump should I choose?
Choose Leyuncot Hydraulic Pump if your mower matches its Toro Z Master Z500 or listed Exmark Lazer fit and its 103-7262 or 116-2444 references. For a specified Exmark Lazer Z deck or serial range, NEWZQ Hydrostatic Pump gives detailed 52-, 60-, and 72-inch fit information; Exmark 103-2675 Pump is another specifically named Lazer Z AC, AS, and LC option. Scag Wildcat or Tiger Cub owners can consider Hydro-Gear PG-1GCC Pump, while YUVANT Gear Pump targets listed Exmark and Gravely applications.
If you need to address a Hydro-Gear transmission leak, check whether the sixcow Charge Pump Kit matches your transmission before ordering. In every case, verify the installed part number and mower model against the listing; these products are not universal replacements.

Frequently Asked Questions
How can I identify whether my mower needs a complete hydraulic pump or a charge pump kit?
Check the installed component and its part number, then compare them with the product listing. The charge pump kit here is listed for certain Hydro-Gear transmissions and as a way to address pump oil leakage; other listings describe replacement pumps. Do not choose between them based on the mower model alone.
What should I check on the mower before ordering a replacement pump?
Record the mower’s exact model and the installed pump’s part number, then check both against the listing’s fit details. Compare any stated deck size, serial range, transmission series, and replacement numbers where provided. The products cover different applications, so a similar-looking pump or mower name is not enough to confirm fit.
Can I replace only one hydraulic pump if the mower has two?
The supplied product information does not establish whether replacing just one pump is appropriate for every mower with two. Verify the failed component, its part number, and the mower’s requirements against the listing. If fit or replacement scope is unclear, consult the mower or transmission documentation before ordering.
Why do the replacement part numbers matter?
Replacement numbers help you compare the listing with the pump already installed and confirm that the product is intended for your application. For example, the overall pick lists Toro 103-7262 and 116-Treat those references as a fit check, not as a substitute for confirming the mower model and other stated details.
What should I do if a listing gives several mower or deck fits?
Match your exact mower model and deck size to the specific fit information in that listing. Some products name multiple deck sizes or mower applications, while others identify a narrower range or particular transmission series. Do not assume every version of a named mower fits; confirm the installed part number as well.
Final Words
Start with the installed pump’s part number and your mower’s exact model, then compare those details with each listing’s stated fit. Leyuncot is the practical first choice when its listed Toro or Exmark applications and replacement numbers match. For other applications, consider the specifically listed alternatives, including the charge-pump kit only when its transmission fit applies.
These options are not universal replacements, so verify before ordering.
