Test the Drive Brakes

Proper brake action is essential to safe machine

noise. Hydrostatic brakes and hydraulically-
released individual wheel brakes can appear to
operate normally when they are actually not fully
operational.
Collision hazard. Be sure that the
machine is not in free-wheel or
partial free-wheel configuration.
