OPERATION
PARK BRAKE
The park brake is located on the left side of the machine and operates the brakes on the rear wheels. Push
lever forward to disengage and pull back to engage.
To adjust turn the knob on the end of the handle. For further adjustment you may turn the yokes clockwise to

ADJUSTMENT OF BELT TENSIONER
The belt tensioner controls the tension on the belt from
the engine to the left and right hydro units. The proper
tension of the idler should be in the third notch on the
side of the tensioner. Over tightening the belt will shorten
the life of the belt and the machine may not perform to
the best of its ability. To adjust belt tensioner, loosen the
bolt holding the tensioner. Bring idler pulley tight to the
belt and turn tensioner into belt to the third notch. Us-
ing a pair of channel lock pliers, rotate the upper half of
the tensioner clockwise until the indicator is at the third
notch. Tighten bolt on tensioner.
SPEED BOSS ADJUSTMENT (45-501 SERIAL NO. ZTR001-ZTR092)
The Speed Boss can be adjusted on either end of the speed boss cable. Tighten or loosen the yoke or ball
joint to get desired down pressure. Make adjustment with the actuator in the lifted up position. Check down
pressure before continuing.
