Operation

Driving in Reverse

To move rearward in a straight line, squeeze drive levers into the reverse position.

To turn left or right, squeeze the right hand drive lever to turn left and the left hand drive lever to turn right.

To make a “zero turn”, squeeze either the left hand or the right hand drive lever back into the reverse position while the opposite drive lever is in a forward position at an equal but opposite speed.

Note: For smooth operation of this machine, avoid quick, jerky movements of the drive levers. Move the drive levers smoothly and deliberately.

To stop, squeeze drive levers back to the “neutral” position. Move the neutral lock latches into the “neutral lock” position and release drive levers. Move the speed control lever to the neutral position.

Adjusting the Cutting Height

WARNING

When the two front support rod hairpins are removed from the mower deck, the weight of the tractor section may cause the front frame of the unit to rise suddenly. If the unit rises suddenly, injury may occur.

Securely hold down the front of the unit when the front support rod hairpins are removed.

The cutting height of the mower deck is adjusted from 1 1/2 to 4 1/2 inches (3.81 cm to 11.4 cm) in 1/2 inch increments.

1.Stop the machine and move the drive levers to the neutral locked position.

2.Disengage the PTO.

3.Engage the park brake.

4.Stop the engine, remove the key and wait for all moving parts to stop.

5.Install hairpin clips in the holes for the desired cutting height. See Figure 6.

Important: To maintain correct cutting height and rake, check the following for proper adjustment.

A.The front and rear hairpins are in the same holes with the proper spacers under the hair pins. See Figure 6.

B.The tire pressures are set as directed in Check Tire Pressures in the Maintenance section.

C.The length of the rear deck support link assemblies average 6.89 inches (approximately 6 7/8 inches) (175.01 mm) from the center of the balljoint to the center of the farthest hole. See Figure 7.

Note: All four pins must equally support the weight of the deck. Adjustment in the length of the rear deck support assemblies may be necessary. If one side is longer than 6.89 inches (approximately 6 7/8 inches) (175.01 mm), than the opposite side must be shorter by the same amount.
