On which axle do the tractor’s service brakes act?
- Correct answer: The rear axle.
- There are no service brakes in a tractor.
- The front axle.
- On all axles.
Why this is the answer
The correct answer in the official bank: The rear axle.
On a farm tractor, the service brakes, worked by the foot pedals, act only on the rear axle wheels, which carry most of the tractor's weight. The front wheels mainly steer and usually have no brakes. There are normally two separate pedals for the left and right rear wheels, which should be locked together when driving on the road so braking is even and the tractor does not swerve.
