Description
If you’ve been hearing whining noises from your front axle or feeling excessive play when you engage four-wheel drive, your planetary gears might be telling you it’s time for a replacement. These gears are the workhorses inside your drive hubs, taking the power from your differential and converting it into the right speed and torque to keep your front wheels pulling strong through mud, hills, and heavy work.
What You’re Getting
- Hardened steel construction that handles the shock loads from hitting rocks and stumps
- Precision-cut gear teeth that mesh smoothly and distribute stress evenly
- Heat-treated surfaces that resist wear even under constant loader work
- Direct replacement that fits your existing drive hub without modifications
Built for Real Farm Work
This gear fits a wide range of New Holland tractors from the 40 and 60 series utility models up through the big T7 row-crop machines, plus the popular TM, TS, and TSA series. Whether you’re pushing silage with a loader, pulling through spring mud, or climbing steep ground to check cattle, these tractors depend on their four-wheel drive systems to keep you moving when two-wheel drive just won’t cut it.
Made to Last
Farm work is hard on drive components, especially when you’re running a loader or doing heavy draft work. This planetary gear uses the same materials and heat treatment as the original equipment, so it’ll handle everything from the constant vibration of field work to the sudden shock of hitting hidden obstacles. The precision manufacturing ensures smooth operation and long service life.
Good to Know
Replacing planetary gears requires draining the front axle and removing the hub assembly – plan on most of a day for this job. Mark all the parts with a paint pen before disassembly since planetary carriers can go back together multiple ways, but only one is correct. Clean everything thoroughly and use fresh gear oil when you reassemble – old, contaminated oil will quickly damage your new parts.
