CARE AND MAINTENANCE - MODEL 560
MOWER DECK SERVICE
CUTTER BLADE REMOVAL - BELT TENSION:
"CAUTION" The removal of the cutter blades for either sharpening or replacement is best
accomplished by removing the deck assembly from the mower. DO A/OTattempt
to raise or lift the front of the mower unless proper safety equipment is available
to support the mower. If you do not have the necessary equipment, entrust this
task to your dealer.
DECK REMOVAL:
1. Remove front belt access cover from body. Stand in front of mower, grasp lift quadrant
lever with left hand. Move lever to align with the 5th hole from the bottom on the quadrant
plate. At this time, connect brake link into hole on lift lever. Move lift lever toward lowest
cut position and remove belt from the top of center deck hub assembly.
2. Remove the hair pin cotters from the ends of the deck support rods. Slide deck support
rods from deck while supporting deck assembly with a suitable brace, or by the use of
an assistant to hold the deck while rods are removed. Slide deck from under chassis.
3. Reverse procedure to re-install deck assembly.
CUTTER BLADE REMOVAL:
1. Carefully place deck assembly in a manner which will allow access to the blade bolts.
Hold blade from turning while bolt is removed from the center of each hub assembly.
"Caution" wear heavy, thick gloves when holding onto cutter blade, avoid the sharp
edge of the blade.
2. When reassembling blades to hub assemblies, fully tighten blade bolts to a minimum
of 50 ft. lbs. torque. The use of air impact tools is recommended for installation to insure
bolt tightness.
BELT TENSION:
1. The engine to mower deck drive belt on the Model 560 is automatically held in proper
tension by springs which push the deck assembly forward, and does not require any
additional adjustment to be made. Both the belt and the idler system should be
periodically inspected due to the nature of the job they perform.
2. Serpentine deck belt tension is maintained by a manual adjustment rod which is located
on the top of the mower deck assembly. Proper belt tension is critical to insure cut
quality. If adjustment is required, tighten lock nut on adjustment rod until belt free play
or movement between pulleys is approximately 1/4 of an inch.
