The 846639, 497672, 497157, 495733, 694393, and 692734 references provide several lookup routes, while specific 33R877 and 31R907 variants help refine the engine match. Those identifiers are practical when sourcing a maintenance part, but the supplied details do not establish a universal mower fit, so checking the engine code is the useful first step.

Skip it if you need a 12V Kubota solenoid with a specified 3-spade connector; Zreneyfex’s 16851-60014 lists both.

This HNeekyr solenoid is best suited to owners whose lawn or garden engine matches the listed 846639 references and model codes. Its application details are concentrated on specific engine families, making exact model matching the key boundary.

Best for: Simple 846639 engine replacement.

Why it ranks #5: Offers a direct-fit replacement for lawn and garden equipment and lists six cross-reference numbers, including 846639 and 694393.

The solenoid stops fuel flow when the engine is turned off, so the replacement addresses the stated shut-off function rather than a general fuel-system upgrade. Its cross-reference list gives owners several part numbers to compare, and the direct-fit claim supports a replacement-oriented workflow for lawn and garden equipment. The supplied repair note recommends work gloves and a well-ventilated area, practical precautions when carrying out the repair around the engine and fuel system.

Skip it if you need named compatible mower models; IFYKIM’s 846639 listing identifies selected Craftsman and John Deere models.

This HiFeedor part is for owners using the 846639 or a listed cross-reference on lawn and garden equipment. Its model-level application details are limited, so buyers should rely on a matching original part reference rather than a broad mower description.
