The wheel motors used on Groundsmaster 3200/3300/3310 machines are
Parker Torqmotor™ motors of the same basic design with minor differences. The
front wheel motors are TG series motors, and the rear wheel motors are TL
series motors. The motor displacements vary between models. The right side
wheel motors have a reverse timed manifold to allow correct rotation direction for
forward and reverse. The left side wheel motors are identified with a yellow dot
on the motor housing near the B port.
