This replacement part is supplied directly from the original equipment manufacturer. It is specially designed for Toro riding lawn mowers and garden tractors. The gear-pinion assembly is an important component which allows a user to steer the unit. It attaches to the steering shaft, and it interacts with gear-steering. This is an identical replacement for a damaged or a missing part that was installed on a new unit. Keep in mind this high-quality component is made of durable metal and is sold individually. Make sure to refer to the diagrams of your model for the correct installation of the new part. You will need a wrench set to perform this repair.
