2 Pack GY22172 Idler Pulley Replaces GY20067 Idler Pulley John Deere GY22172 Idler Pulley John Deere Flat Idler Pulley - GY22172 for D110 D130 D140 L110 L120 L130 LA105 LA115 LA145 Tractors

What It Is

This is a flat idler pulley that routes and tensions the mower deck belt on select John Deere lawn tractors. It replaces OEM part numbers GY22172 and GY20067, and is sold as a 2-pack for $18.98.

Fitment & Compatibility

Before buying, verify your tractor model and deck size. This pulley fits John Deere D110, D130, D140, L110, L120, L130, LA105, LA115, and LA145 tractors—typically with 42-inch or 48-inch decks. Measure the pulley’s outside diameter (must match your old one—usually about 4 inches) and check that the bearing is a standard 6202 type. It is an aftermarket part, not OEM John Deere, so confirm that your existing pulley uses a smooth, flat surface (not grooved). Also ensure the center hole diameter and bolt pattern match your spindle arm.

Key Things to Know

• Quality: Made of steel with a sealed ball bearing. User reviews (4.7/5 from 761 ratings) report good durability for residential use.
• Installation: Moderate difficulty—requires removing deck belt, prying off the old pulley, and pressing in the new one. A puller or socket may help.
• Common gotcha: Some users note the bearing may be slightly noisier than OEM. If you need whisper-quiet operation, consider OEM.
• Pack value: Two pulleys for under $20 is a strong deal if both are needed or as a spare.

Should You Buy It

This is a solid, budget-friendly replacement for homeowners with the listed John Deere tractors who need to fix a worn or seized idler pulley. It works well for routine maintenance and is backed by strong ratings. If you require exact OEM fit or noise-free operation, stick with John Deere branded parts.
