Husqvarna BZ7234TD/968999264 Cutter Housings, Deck Lift Power Unit, Mule Drive System Adjustment

MAINTENANCE

Begin with either side and put the motion control lever into the neutral position. Adjust the motion control linkage by rotating the double nuts (D) in the proper direction until the wheel stops rotating. See illustration. Move the motion control lever forward then into the neutral position and place it into the neutral slot. The wheel must be stopped completely at this point. Now do the same in reverse and release the lever. The lever should return to neutral on its own.

Run engine full throttle to make sure wheels do not rotate. Readjust if any rotation occurs.

Repeat the whole process for the opposite side and tighten the nuts against the ball joints.

Turn machine off.

Cutter Housings

Grease housings once weekly or every 40 to 50 hours of use. Use a good synthetic grease. Pump grease in until a small amount purges from the popet on the underside of the deck. Check the torque of the pulley bolt 45 ft/lbs should be maintained.

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

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.
