Seat Position, Blade Brake/PTO | Yard-Man 13B-325-401 guide

Seat Position

The seat position on the rider mower can be adjusted to maximize the operator’s convenience.

•Stop the mower completely and engage the parking brake. Turn ignition off.

•Pivot the hood assembly up.

•Loosen the four self-tapping screws on the bottom of the seat.

•Slide the seat forward or backward in the slot, and position it as desired. Retighten the four screws.

Blade Brake/PTO

The blade engagement pedal should be adjusted so that if you depress it about 3/4” from the front of the slot, it should start engaging the deck belt. The PTO (power take off) switch is located in the blade brake slot on the left side of the upper frame. See Figure 12 . The brake engagement pedal needs to make contact with the PTO switch for the engine to start.

Under normal operation, the blade engagement pedal should not require frequent adjustment. However, perform the following test periodically and make sure that it is in fine working condition.

•	Pivot the hood assembly up and check if there is
	enough slack on the deck engagement cable.
•	Depress the blade engagement pedal (about 3/4
	inch) and check if the belt is engaging.

•If the belt is slipping when you depress the blade engagement pedal about 3/4”, loosen the two hex nuts on the cable. See Figure 12.

•If the belt is engaging sooner than when the blade engagement pedal is 3/4” from the PTO switch, tighten both hex nuts on the cable. See Figure 12.

•Repeat the blade engagement test and readjust if necessary.

•Pivot the hood assembly back.

Wheel Alignment

The front wheels should toe-in 1/16-5/16 inch. To adjust toe-in, follow these steps:

•Remove the 3/8’’ hex nut which holds the ball joint to the steering segment. See Figure 13.

•Adjust the ball joint in or out until the wheels toe-in approximately 1/16-5/16" (Dimension ‘‘B’’ should be approximately 1/16-5/16" less than dimension ‘‘A’’). See Figure 13.

•Replace the ball joint into the steering segment, and replace the 3/8’’ hex nut.

Adjusting the Deck

IMPORTANT: Perform adjustments to the deck on a flat, level surface. Before continuing with deck adjustment, check air pressure in all four tires. Recommended air pressure is 12 psi. Please note that the valve stems on this rider mower are on the inside of the front wheels and on the outer side of the rear wheels.

•Lift the hood assembly and remove grass catcher from the rider mower. Place the deck in the highest position.

•Inspect rear of deck. The front of the deck should be approximately 1/4” to 3/8” lower than the rear of the deck. To maintain that, you may have to adjust the deck pitch. If the deck is contacting the cable bracket on the front of the transmission, you will have to adjust the rear deck height. Follow the steps on next page for adjustments.
