Description
When your PTO won’t engage smoothly or you’re getting grinding noises from the transmission, it’s often the internal PTO gear that’s showing wear. This gear is the workhorse inside your transmission that transfers power from the engine to the PTO shaft, and when it starts slipping or wearing down, your implements don’t get the consistent power they need to do their job right.
What You’re Getting
- Precision-cut gear teeth that mesh smoothly with your transmission components
- Heavy-duty steel construction built to handle the torque loads of PTO operation
- Heat-treated for maximum durability against wear and deformation
- Factory specifications ensure proper timing and power transfer
Built for Real Farm Work
This internal PTO gear keeps your Fiat 90 series tractor running everything from rotary cutters and mowers to balers and manure spreaders. These tractors are the backbone of mid-size farming operations, handling everything from hay production to livestock feeding, and they need reliable PTO power to keep your operation moving during those time-sensitive windows when weather and crops wait for no one.
Made to Last
Inside your transmission, this gear faces constant stress from engagement cycles, torque loads, and the heat of operation. Quality materials and precise manufacturing ensure it maintains proper mesh with adjacent gears while handling the full power your engine delivers to your implements.
Installation Notes
This is an internal transmission component that requires splitting the tractor for installation—definitely a job for someone comfortable with major tractor repairs. While you’re in there, it’s smart to inspect the PTO clutch, shaft, and related bearings since you’ve got everything apart. Keep the old gear as a core if it’s not completely destroyed.
