Husqvarna BZ 27, BZ 34 manual Deck Lift Power Unit, Mule Drive System Adjustment, Caster Wheels

MAINTENANCE

Deck Lift Power Unit

The system is pre-filled and factory sealed. In the event it becomes necessary to replace oil in the reservoir, the cylinder or cylinders must be in the retracted position. Carefully remove all dirt and debris from around the fill plug and remove the plug. Fill to the lower edge of the hole with 15W-50 synthetic oil and replace the plug firmly to reseal the system.

Mule Drive System Adjustment

Only for the 72” deck.

As the mule drive belt wears and elongates, some spring tension must be maintained on the left (self-adjusting) mule drive idler.

For best performance, occasionally adjust the right (fixed) mule drive idler position in the slot so central axis of idler pulleys align.

Caster Wheels

Check every 200 hours. Lift front of unit off of ground so caster wheels can rotate freely. Tighten caster bolt (34) then back off 1/2 turn. Check that wheel rotates freely. If wheel does not rotate freely back the caster bolt off in 1/4 turn increments until wheel rotates freely.

IMPORTANT INFORMATION

DO NOT add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures.

Only use O.E.M. specified tires.

Foam filled tires or solid tires will void the warranty.
