Description
If you’ve noticed grinding noises when shifting gears or the transmission feels sluggish under load, worn planetary gears might be the culprit. This planet gear is part of the complex gear train inside your John Deere’s transmission that transfers power smoothly through different speed ratios. When these gears wear out, you’ll lose that crisp shifting feel and risk more expensive transmission damage down the road.
What You’re Getting
- Precise 39-tooth gear count engineered for proper speed ratios and smooth power transfer
- Heat-treated construction that handles the constant stress of field work and heavy pulling
- Direct OEM replacement – no modifications or adapters needed
- Machined to exact specifications for proper meshing with other transmission components
Built for Real Farm Work
This planet gear fits John Deere 6010 series tractors like the 6210, 6310, and 6410, plus their L variants, along with the 6320L from the 6020 series. These are the utility and row-crop machines that handle everything from loader work around the farmyard to pulling planters and cultivators through the field. When you’re counting on your tractor for daily chores and seasonal operations, transmission reliability isn’t optional.
Made to Last
Quality gear steel and proper heat treatment ensure this planet gear stands up to the torque loads and vibration that come with farm work. The precision machining maintains proper clearances and tooth contact patterns, preventing premature wear and keeping your transmission running smoothly for years to come.
Good to Know
Replacing planetary gears requires splitting the tractor and significant transmission disassembly – it’s a job for an experienced mechanic or dealer service department. While you’re in there, it’s smart to inspect other transmission components and replace anything that shows wear. Fresh transmission oil and filters are essential after any internal work.
