Installation follows the same mount points as the original shaft and usually requires basic hand tools. Expect to remove the steering wheel and lower steering housing, slide the new shaft into the gearbox spline, and secure with the original fasteners.

• Time: generally 30–90 minutes depending on access and experience.
• Tip: verify spline engagement and steering free play before finishing assembly.

What should I inspect before buying to ensure this is the right part?

Measure the length and compare spline shape and hole locations to your current shaft. Cross-reference your tractor’s model and OEM part numbers to avoid purchasing an incompatible shaft.

• Confirm overall length is 21" and splines match gearbox input.
• Check existing part numbers stamped or printed on the old shaft.
• Compare mounting hole spacing and any retained clips or pins.
