MTD Replacement Part Pivot Bar Kit

What It Is

The MTD Pivot Bar Kit is a replacement linkage component that connects the mower deck to the lift mechanism on lawn tractors and zero-turn mowers. It allows the deck to pivot and follow ground contours for a consistent cut.

Fitment & Compatibility

• Check your model number – This kit fits many MTD, Cub Cadet, Troy-Bilt, and Yard-Man models with 42- to 54-inch decks. Look up your unit’s model/serial number on the MTD parts site or your manual.
• OEM vs aftermarket – This is an OEM MTD part (often part number 918-04128 or 718-04128). Aftermarket bars may vary in thickness or pin diameter; if you need exact match, stick with OEM.
• Measure your old pivot bar – Overall length, pin hole diameter, and the distance between mounting holes. Compare to the kit’s specs (typically ~10-12 inches long, 5/16-inch pin holes) to confirm fit.
• Deck type – Works with side-discharge, mulching, and bagging decks that use a single pivot bar on the rear of the deck. Not for decks with dual pivot links or independent suspension.

Key Things to Know

• Quality – Steel construction with zinc coating resists rust better than many aftermarket bars. Bushings are pre-installed and greased.
• Installation difficulty – Moderate: you’ll need a socket set, penetrating oil for rusted bolts, and possibly a pry bar to align the deck. Allow 30-60 minutes.
• Common gotchas – The deck must be fully lowered and supported before removing the old bar. The pivot bar holes can wear oval over time; check the deck bracket holes too. If they’re worn, replace the brackets as well.
• Warranty – MTD OEM parts carry a 1-year warranty against defects; aftermarket bars usually have none.

Should You Buy It

If your mower deck sags, won’t level, or clunks when turning, and you’ve confirmed the pivot bar is bent or the bushings are worn, this kit is a direct, durable fix. It’s best for owners of MTD-family tractors who want a hassle-free, OEM-matched replacement rather than guessing with generic bars. Skip it if your deck brackets or lift arms are also damaged—you’ll need those parts too.
