Why is a differential needed

Most summer residents prefer to purchase country equipment with a differential, and beginners do not quite understand how such a single-axle tractor differs from a conventional one. In simpler and unprofessional terms, it is customary to call a differential a blocking swivel extension. The main function performed by the described component of the walk-behind tractor is to reduce the radius when turning the equipment. Accordingly, it becomes possible to make a larger wheelbase, to increase the plowing width. The equipment does not tip over when cornering, while it demonstrates amazing maneuverability.

At the time of using the differential, one wheel is blocked, that is, the wheels begin to act independently of each other, as a result of which the turn is easier (turn in place).

Another benefit of a differential is to use a retaining bolt and move it from a bore in the hub to a cylindrical recess. In this case, the element can play the role of an extension, which allows you to increase the wheelbase of the equipment.
