732-04287 Extension Spring Fits MTD, Troy-Bilt, Craftsman, Cub-Cadet,Bolens, Remington, Yardman, Yard-Machine, White, Huskee, LawnChief, Ryobi Lawn Mowers

What It Is

The 732-04287 extension spring is a replacement part for the deck height adjustment mechanism on many MTD-built lawn tractors and push mowers. It provides tension to keep the deck lift lever or linkage engaged, ensuring consistent cutting height control.

Fitment & Compatibility

Before buying, verify three things: (1) Model number – this spring fits specific MTD, Troy-Bilt, Craftsman, Cub Cadet, Bolens, Remington, Yardman, Yard-Machine, White, Huskee, LawnChief, and Ryobi models built by MTD; check your mower’s model plate (usually under seat or on frame). (2) OEM number – matches MTD 732-04287, 732-05072, and others; cross-check with your machine’s parts diagram. (3) Measurements – the spring is approximately 3.5 inches long with 0.5-inch inside diameter hooks; measure your old spring to confirm length and hook size. It is not universal for all deck sizes or brands outside MTD’s ecosystem.

Key Things to Know

• OEM equivalent – this is a direct replacement for the original MTD part, not a universal aftermarket spring; fitment is precise for MTD-based decks.
• Installation difficulty – easy (5–10 minutes) with basic pliers and a hook tool; no special skills needed.
• Common gotcha – the spring can snap if stretched too far during installation; use a spring puller or pliers to avoid over-extension.
• Quality – zinc-plated steel resists rust but may wear faster in wet conditions; check for deformation before installing.

Should You Buy It

If you own an MTD-family mower (Troy-Bilt, Craftsman, Cub Cadet, etc.) and your deck height spring is broken or stretched, this is the correct, cost-effective fix. At $9.69, it’s a cheap, easy repair that restores proper deck lift function. Skip it if your mower uses a different spring system (e.g., cable-driven or non-MTD brand).
