Massey Ferguson 725-1657A Spare Part - Sw:intlk:no/nc Snap Mt

Original MTD Safety / Seat Interlock Switch — Part 725-1657 (superseded by 925-1657A). Reliable plunger-style safety switch designed to interrupt the engagement/ignition circuit when the operator leaves the seat, restoring the intended safety behavior on many MTD riding and garden tractors.

Key details:

- Function: seat/safety interlock (detects operator presence).

- Form factor: plunger-style snap‑in switch with a compact rectangular body — overall size approximately 104 mm × 81 mm × 48 mm (length × width × height).

- Electrical/mounting: available in common single‑ and double‑pole configurations with multiple terminal options depending on the revision — fits into a snap mount and uses a plunger actuator; check your tractor’s harness for terminal count and wiring orientation before fitting.

- Cross-reference: original part 725-1657 is shown as replaced by MTD part 925-1657A on official parts listings. This is listed among MTD parts as the safety switch for various riding tractors.

Example fitments (verify against your model plate before ordering): listings show this switch used on mid‑1990s MTD lawn tractors such as model 132-080 (MTD lawn tractor) and several Hechinger/Select series riding tractor model variants that reference part 725-1657 in their diagrams. Confirm your product’s model number (usually on the underside of the seat pan for riding mowers) to ensure compatibility.

Why choose this: if your tractor won’t engage or the mower cuts out when you sit/stand, this original MTD safety switch is the exact replacement used in factory parts diagrams to restore correct seat‑interlock function — one of the essential power tool parts to get your mower back to safe operation.
