Exmark Series X manual Pump Drive Belt Tension, Deck Belt Tension, Adjusting the Parking Brake

Maintenance

16.If the deck is too low, tighten the single point adjustment bolt by rotating it clockwise. If the deck is too high, loosen the single point adjustment bolt by rotating it counterclockwise.

Note: Loosen or tighten the single point adjustment bolt enough to move the height-of-cut plate mounting bolts at least 1/3 the length of the available travel in their slots. This will regain some up and down adjustment on each of the four deck links.

17.Re-tighten front and rear height-of-cut plate mounting bolts.

Important: Torque the front and rear height-of-cut plate mounting bolts to 27-33 ft-lb (37-45 N-m).

18.Repeat steps 9 through 13.

Check to make sure brake is adjusted properly. This procedure must be followed after the first 100 hours or when a brake component has been removed or replaced.

1.Drive the machine onto a level surface.

2.Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake.

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

4.Raise the back of the machine up and support the machine with jack stands.

CAUTION

Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

5.Remove the rear tires from the machine.

6.Remove any debris from the brake area.
