MAINTENANCE
Blower housing and transfer tube
WARNING: Never work on the blower assembly or
mower deck when the tractor engine is running.
WARNING: Clean flammable material from machine.
Prevent fires by keeping engine compartment, top of
deck, exhaust area, battery, hydraulic lines, fuel line,
fuel tank and operator’s station clean of accumulated
trash, grass clippings, and other debris. Always clean
up spilled fuel and oil.
The blower and tube assembly (Figure 5-1) should be kept
clean and free of any accumulation of matted clippings or other
obstructions. Occasional clogging may also occur when
working in heavy, wet or matted grass.
WARNING: Never place hands or feet into the blower
housing spout. There is an impeller located inside the
housing that will cause severe injury. Use a probe to
clean debris from spout.
WARNING: Never engage mower deck unless the
catcher box is installed and the door is closed. Also,
the transfer tube assembly must be in place on the
blower outlet and the box assembly and the bungee
cord is connected.
To service the blower housing: remove the clevis pin and
swing the housing away from the deck.
To service the transfer tubes, remove the tube assembly from
the unit. The tube assembly can be cleaned by using soapy
water and washing the inside of the tubes with a pressure
washer. Rinse with water.
To clean the catcher box, use a power washer.
Blower drive belt
The blower drive belt (Figure 5-2) is located under the belt
shield. This belt is spring tensioned and should not need
adjustment. When replacing the belt the spring extension
should be 6” hook to hook.
To inspect or replace, remove the clevis pin and swing the
housing open. This loosens the belt and allows it to be
removed.
When belt replacement becomes necessary, check the
condition of the pulleys. Clean the grooves and check for
excessive wear. A new belt should not run against the bottom of
groove. If it does bottom out, the the pulley needs replacing.
Blower spindle jack shaft
The blower spindle jack shaft assembly requires lubrication
after every 500 hours of use or annually, whichever occurs first.
The spindle is equipped with two grease zerks (Figure 5-3).
They are accessible by unlatching the blower housing from the
deck and pivoting it outward. Use SAE multi-purpose grease,
fill until grease flows from side of zerk (one or two ounces
maximum).
