Best Hydraulic Pump For Zero Turn Mowers: Compare Replacement Pumps

#1 · Best Overall

1. RONGPAS BDP-10A-427 Pump

• Weight: 9.31 lb

Best for: BDP-10A-427 cross-reference buyers.

Why it ranks #1: Cross-references Ariens, Exmark, Toro, Stens, and Hydro-Gear numbers, with listed Lazer Z serial and Toro Z Master deck compatibility.

A broad cross-reference set centered on BDP-10A-427 gives this RONGPAS pump a clear identification route for several mower brands. Its stated applications include Exmark Lazer Z serial number 370,000 and newer and specified Toro Z Master groups, with deck sizes called out by series.

The listing names replacement references for Ariens 02964400, Exmark 103-2675 and 103-1943, Toro 103-1943, Stens 025-007, and Hydro-Gear BDP-10A-427 and BDP-10A-433. For fit, it specifies Exmark Lazer Z serial 370,000 and newer with 52-, 60-, and 72-inch decks, plus Toro Z 250's 742XX and Z 500's 2004-and-newer applications. Those details support a careful parts lookup across brands; the stated package includes one pump.

Skip it if you cannot match your Toro series and deck or Exmark serial range; the listed applications are not interchangeable across all models.

A sensible choice for owners cross-checking a BDP-10A-series pump against the named Ariens, Exmark, Toro, or Stens references. Confirm the exact mower series, serial range, and deck size before choosing this replacement.

#2 · Broad Deck Coverage

2. NEWZQ BDP-10A Pump

• Dimensions: 9.65 x 7.87 x 7.87 in
• Weight: 9.26 lb

Best for: Lazer Z and Toro deck coverage.

Why it ranks #2: Lists Exmark Lazer Z serial numbers 370,000 and newer with 52-, 60-, and 72-inch decks, plus Toro Z Master applications.

Compatibility spanning Exmark Lazer Z serial number 370,000 and newer and several Toro Z Master groups gives this NEWZQ pump a broad, clearly enumerated application. The listing specifies multiple deck sizes across those mower families, helping owners narrow selection by serial range, model group, and deck configuration.

For Exmark, the stated fit covers Lazer Z serial number 370,000 and newer with 52-, 60-, and 72-inch decks. Toro applications include Z 250's Z Master 742XX Series with 52-, 62-, and 72-inch decks, plus Z 500's Z Master 2004-and-newer hydraulic group with 60- and 72-inch decks. Those distinctions are useful for checking a replacement against the mower's series and deck. The listing also supplies BDP-10A-427, BDP-10A-433, 103-2675, and 103-1943 references for part-number comparison.

Skip it if you cannot identify your Toro series or deck size; the listed Z 250's and Z 500's applications have different coverage.

A useful candidate for owners of the named Exmark Lazer Z or Toro Z Master groups who can verify serial range and deck size. The varied Toro coverage makes those details important before ordering.

#3 · Toro Exmark Match

3. Leyuncot PK-BGAB Pump

• Dimensions: 4.4 x 3.6 x 4.9 in
• Weight: 9.9 lb

Best for: Toro and Exmark part-number match.

Why it ranks #3: Lists replacement numbers 103-7262 and 116-2444 and fit for Toro Z Master Z500 and Exmark Lazer models.

The 103-7262 and 116-2444 cross-references give this Leyuncot pump a useful identification route for owners repairing compatible Toro Z Master Z500 or Exmark Lazer mowers. Its listed fit covers Z500 models from 2004 onward with 60- or 72-inch decks, making mower series and deck size central to the decision.

Alongside the PK-BGAB-EY1X-XXXX and PJ-BGAB-EY1X-XXXX identifiers, the listing names Toro 103-7262 and 116-2444, which helps owners compare the installed pump's number before ordering. Applications include Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks and Exmark Lazer AS and Lazer Z AC/AS/LC models. The stated dimensions are 4.4 by 3.6 by 4.9 inches. Confirm model and part-number correspondence; the product information does not establish compatibility beyond those named applications.

Skip it if you have a Toro outside the stated Z500 range or a different deck size; the listing names only 60- and 72-inch decks.

This suits owners matching a listed 2004-or-newer Toro Z500 or named Exmark Lazer model by pump number. Its application details are specific, so confirm both the mower family and deck configuration before choosing it.

4. Beenhuco 103-7262 Pump

• Dimensions: 4.8 x 4.3 x 3.5 in
• Weight: 9.44 lb

Best for: Toro Z500 and Exmark Lazer fit.

Why it ranks #4: Covers the same stated 103-7262 and 116-2444 references, Toro Z500 models from 2004 onward, and Exmark Lazer variants.

The 103-7262 and 116-2444 reference numbers make this Beenhuco pump identifiable for owners comparing a replacement with a Toro or Exmark pump listing. Its specified applications include Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks and several Exmark Lazer families.

The product names Exmark Lazer AS and Lazer Z AC/AS/LC alongside the Toro Z500 range, so owners can check their mower family before investigating further. Its listed reference numbers also include PK-BGAB-EY1X-XXXX and PJ-BGAB-EY1X-XXXX, providing additional identifiers for a parts comparison. The dimensions are 4.8 by 4.3 by 3.5 inches, and the stated weight is 9.44 pounds. Since the Toro fit is tied to model year and deck size, use those details together with the pump number when assessing compatibility.

Skip it if you own a Toro Z Master outside the stated Z500 range; the listing does not name other Toro groups.

This fits the search for owners of listed Toro Z500 or Exmark Lazer models who can match the pump references. For Toro, check both the model year and deck size rather than assuming coverage across the full Z Master line.

#5

5. MujaUdg PK-BGAB Pump

• Dimensions: 5.5 x 5.5 x 7.87 in
• Weight: 9.48 lb

Best for: Toro Z500 and Exmark owners.

Why it ranks #5: Lists Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks, plus Exmark Lazer AS and Z variants.

Compatibility with Toro Z500 Z Master mowers from 2004 onward, including 60- and 72-inch deck configurations, gives this replacement a clearly defined application. MujaUdg also lists Exmark Lazer AS and Lazer Z AC/AS/LC models, helping owners of those named mower families identify a pump option without relying on a universal-fit claim.

The listing says the pump matches factory specifications for the stated Toro zero-turn mowers and installs without modifications to existing hydraulic lines. That detail matters to owners seeking a replacement that works with their current line arrangement. Its additional Exmark Lazer AS and Lazer Z AC/AS/LC compatibility broadens the named fit range beyond Toro. Before selecting it, compare the mower model and deck size with the stated Z500 applications; the product information does not list other Toro series.

Skip it if you own a Toro outside the listed Z500 range; the product information identifies Z500 and specified Exmark Lazer families only.

Consider it if your mower is a listed Toro Z500 from 2004 onward or a named Exmark Lazer model, and the deck configuration matches. Owners of other Toro series need a pump with explicitly matching applications.

#6

6. NEWZQ BDP-10A-414 Pump

• Dimensions: 9.65 x 7.87 x 7.87 in
• Weight: 9.15 lb

Best for: Specified Exmark Lazer Z models.

Why it ranks #6: Replaces 103-1942 and lists specific Exmark Lazer Z CT and HP mower configurations, including serial ranges and engine details.

The 103-1942 and BDP-10A-414 replacement references anchor this pump to a set of specific Exmark Lazer Z applications. NEWZQ identifies both 52-inch Lazer Z CT and 46-inch Lazer Z HP configurations in the supplied details, giving owners a model-and-serial-based route to evaluate the replacement.

The listed 52-inch Lazer Z CT application uses an 18-hp Briggs & Stratton engine and includes serial ranges 510000–539999 and 540000–599999, both identified as 2005 models. The 46-inch Lazer Z HP application is specified with a 19-hp Kawasaki engine and serial ranges 600000–669999, 670000–719999, and 720000–789999 across the listed 2006–2008 models. These distinctions can narrow a repair search, but buyers need to match mower model, engine, and serial range rather than relying on deck size alone.

Skip it if you have a mower whose model, engine, or serial range is outside the listed Exmark Lazer Z applications.

A focused option for owners of the specified Exmark Lazer Z CT or HP configurations who can verify engine and serial details. The application list is narrow, so broader mower-family similarity is not enough to establish fit.

#7 · Multi-Brand Fit

7. MujaUdg PG-1KCC Pump

• Weight: 1.5 lb

Best for: Scag and multi-brand gear-pump buyers.

Why it ranks #7: Lists replacement references for Scag, Ariens, Dixie Chopper, Dixon, Husqvarna, Hydro Gear, and Snapper mower applications.

A wide set of replacement references—including Scag 482643, Ariens 2964300, and Hydro Gear BDP-10A-316—sets this MujaUdg gear pump apart for owners identifying a unit by its existing part number. Its metal housing, precision-machined internals, and pressure-resistant seals are listed for demanding mower hydraulic systems.

The manufacturer describes stable hydraulic flow and pressure as supporting smooth forward and reverse travel, responsive speed control, and consistent power transfer. Those operating benefits are tied to the listed pump function rather than a generic mower claim. The replacement references also span Scag, Ariens, Dixie Chopper, Dixon, Husqvarna/Dixon, Hydro Gear, and Snapper applications, giving owners several brand-specific starting points. The supplied information names compatible Scag model families including STWC, Tiger Cat, and Tiger Cub; match the actual pump number and mower application before ordering.

Skip it if you cannot identify a matching listed part number; the broad brand list does not specify fit for every mower model.

Suitable for owners of listed Scag, Ariens, Dixie Chopper, Dixon, Husqvarna/Dixon, Hydro Gear, or Snapper applications who can cross-reference the original pump. Verify the specific model and number because brand names alone do not settle fit.

#8

8. RONGPAS BDP-10A-440 Pump

• Weight: 9.28 lb

Best for: Hydro Gear BDP-10A replacements.

Why it ranks #8: Lists BDP-10A compatibility and references for Bobcat, Husqvarna, and Gravely, including Husqvarna ZT 200 Series.

The BDP-10A-440 replacement reference is the key differentiator here, giving owners of listed Hydro Gear BDP-10A systems a direct part-number path when sourcing a hydraulic gear pump. RONGPAS also lists several mower and equipment cross-references, so buyers can compare their existing pump identification against a broad set of named applications.

Compatibility is specified for the Husqvarna ZT 200 Series and Hydro Gear BDP-10A Series, while the replacement list also names Bobcat 4121333, Husqvarna 132146, and Gravely 21553400. Those references make the pump useful for an owner matching a worn unit by its original number rather than relying on a general mower description. The listing includes many Bunton, Bobcat, and Ryan model references as well. Check the OEM number and mower model/year before ordering; the listed package weighs 9.28 pounds.

Skip it if you cannot match your OEM number and mower model/year to the listed applications; this listing calls for that verification before purchase.

A practical candidate for owners of listed Husqvarna ZT 200 Series or BDP-10A equipment who can identify the original pump. Its broad cross-reference list helps narrow the search, but exact model and year matching remains essential.

#9

9. Dixie Chopper Left Pump

• Weight: 14 lb

Best for: Dixie Chopper left-hand replacement.

Why it ranks #9: A clearly identified left-hand pump for numerous Dixie Chopper models, including Classic, SP, and XT mower series.

This is explicitly a left-hand Hydro-Gear pump, part 200013DC replacing 200013, which makes orientation the defining selection point. Dixie Chopper lists a substantial group of compatible Classic, SP, and XT mower models, giving owners a direct model-family check when sourcing a left-side replacement.

The application list spans Classic 2550, 2750, 2750HP, 2760, 3060HP, 3360HP, and 3372HP, as well as specified SP3000, SP3200, and XT models. That range helps owners compare the exact mower designation rather than assume all Dixie Chopper machines share a pump. Because the listing identifies the unit as left-hand, position matters as much as the model match. It also advises checking the original part number in the owner's manual or parts diagram to confirm location and fitment.

Skip it if you need the right-hand pump; this Dixie Chopper listing specifically identifies a left-hand unit.

Choose it only if your Dixie Chopper is among the listed models and the required position is left-hand. Owners should use the mower's manual or parts diagram to verify the original number and pump location.

Listed on Amazon as: Left Hand Hydro-Gear Pump for Zero Turn Lawn Mowers / 2550, 2750, 2760, 3060, 3360, 3372, SP3200, XT2800EFI-72, XT3000-60, XT3200-72 / 200013DC, 200013

#10 · Genuine OEM Part

10. Single Cylinder OEM 135-7908

• Weight: 98 lb

Best for: Genuine OEM right-hand pump.

Why it ranks #10: Genuine OEM right-hand pump 135-7908 for Toro Z Master and Exmark LZX, but its listed application is comparatively narrow.

Genuine OEM status and a clearly identified right-hand orientation make this 135-7908 pump distinctive for owners replacing the right-side unit. The listing says that, when seated on the mower, the pump is on the right-hand side, and names Toro Z Master and Exmark LZX mower compatibility.

The 135-7908 model number provides a direct reference for checking the part being replaced, while the right-hand designation clarifies which side of the mower it serves. The listing's orientation note is especially useful during parts identification: it defines right-hand from the seated operator's position, not by looking at the mower from the front. Compatibility is stated for Toro Z Master and Exmark LZX mowers. Match the original number and required side before selecting this pump; the listing does not name broader model details.

Skip it if you need a left-hand pump; this OEM 135-7908 listing specifies the right-hand side from the seated position.

Best suited to an owner replacing the right-side pump on a compatible Toro Z Master or Exmark LZX mower. Verify the 135-7908 number and orientation; the listing provides no more detailed model breakdown.
