Mower Blade Care WARNING! Before performing any maintenance, place the PTO switch in the "OFF" position, engage the parking brake lever, turn the ignition key to the "OFF" position and remove the key from the switch. Protect your hands by using heavy gloves when handling the blades. When servicing the mower deck, be careful not to cut yourself on the sharpened blades. The cutting blades must be kept sharp at all times. Sharpen the cutting edges of the blades evenly so that the blades remain balanced and the same angle of sharpness is maintained. If the cutting edge of a blade has already been sharpened many times, or if any metal separation is present, it is recommended that new blades be installed. New blades are available at your authorized dealer. The blades may be removed as follows. 1. Remove the deck from beneath the tractor, (refer to Deck Removal on page 28) then gently flip the deck over to expose its underside. 2. Use a 15⁄16" wrench to hold the hex nut on top of the spindle assembly when loosening the hex nut securing the blade. A block of wood may be placed between the deck housing and the cutting edge of the blade to help in breaking loose the hex nut securing the blade. See Figure 7-14. Changing the Transmission Drive Belt Several components must be removed and special tools used in order to change the tractor's transmission drive belt. See your Cub Cadet dealer to have the transmission drive belt replaced. Tractor Creeping Creeping is the slight forward or backward movement of the mower when the throttle is on and the speed control levers are in the neutral position. If your mower creeps, see an authorized service dealer. Hex Flange Nut Wood Block Spindle Assembly Figure 7-14 3. When reinstalling the blades, be sure they are installed so that the wings are pointing upward toward the top of the deck. 4. Tighten the blade nuts to 70-90 ft. lbs. 5. Reinstall the deck (refer to Deck Installation on page 30). Section 7 - Service 33
