To level the mower, put the tractor on a level surface. A hard surface such as a garage floor or sidewalk is preferable. 19 Side to Side Leveling The 36 and 44 inch mowers are equipped with two adjustable lift links. This feature allows the mower to be leveled. See figure 32. FIGURE 32. To check the side to side leveling of the deck, place the unit on a hard, level surface. Disconnect the spark plug wire(s). Place the two outer blades parallel to the unit. Measure the distance from the front tip of blade to the surface on each side. If the measurements are not equal, lower the mower deck to the ground. Disconnect one of the adjustable links by removing the hairpin cotter and flat washer which secure it to the deck. Turn the end of the link to the right or left as needed. Reconnect the adjustable link and raise the deck. Recheck the measurement on each side, and repeat adjustment until distances are equal. ■^NOTE If the mower is not level, it will adversely affect the performance. CUTTING HEIGHT The mower can be set in multiple positions. Pull the lift handle back slightly and depress button on top of the lift handle. Release the button when the desired mower position is obtained. To return the mower to a specific position, note the position of the lift lever pointer in relation to the lever position decal before raising or lowering the mower. GAUGE WHEELS AND CASTERS (44-inch Deck) Set the gauge wheels and casters just off the hard surface by locating in the proper holes. The gauge wheels and casters prevent scalping and are not meant to set the cutting height. See figure 33. Gauge wheels and casters must be set in the same relative hole locations. FIGURE 33. 1.

The gauge wheels prevent sca ping and are not meant to set the cutting height. See figure 34. FIGURE 34. STARTING THE MOWER With the engine running at idle speed, start the power take-off clutch by moving the switch to “Run.” Starting the mower with the engine at idle will reduce wear on the drive belt. Increase engine speed to full throttle. ■^NOTE In heavy grass, full throttle may be needed when starting the mowing deck. STOPPING THE MOWER Move the power take-off switch to “Off” and reduce the engine speed. 20 NOTE When installing a new belt always check the condition of the pulleys and if they are not in satisfactory condition, replace them with new pulleys available at your authorized dealer. NOTE Be sure narrow dimension of belt is in bottom of all pulley grooves. CLEANING AND BLADE CARE A WARNING Ü Stop the tractor, disengage the power take-off, place all controls in neutral, engage the brake lock and stop the engine before performing any maintenance. After the first 10 hours of operation check and retighten, if necessary, all nuts and bolts on the machine. Tighten the hex nuts used to attach the blades to the spindles to 50 to 60 Ibf. ft. (68 to 81 N-m). Tighten the hex nuts used to attach the pulleys to the spindles to 90 to 110 Ibf. ft. (122 to 149 N-m). Check and retighten, if necessary, all nuts and bolts once a year thereafter. BLADE SPINDLE ASSEMBLY The blade spindle assembly is a sealed, pre-greased precision pre-set Timken bearing package. Special care must be taken when blade is removed. With blade removed, the shaft and pulley are no longer held and can slip out of spindle housing. If this should occur, bearing spacer (see figure 35) will be free to float since clamping force has been eliminated. To reassemble, insert shaft with pulley into spindle housing, and insert one finger in through the bottom of spindle assembly to line up bearing spacer so that shaft will go through. NOTE Never pound or force shaft through spindle housing. Pulley Bearings Bearing Spacer Dust Shield Spindle Snap Ring Housing Blade At WARNING i Be careful not to cut yourself when sharpening the blades or cleaning the underside of the mower. Clean the underside of the mower at the end of the mowing season and when the build-up of cut material on the underside is noticed. Also, remove the belt cover and remove any accumulation. The cutting blades must be kept sharp at all times. NOTE Sharpen ends evenly so that the blades remain balanced and the same angle of sharpness is maintained. However, if the cutting edge of a blade has been sharpened to within 3/8-inch of the wind wing, it is recommended that new blades be installed. New blades are available at your authorized dealer. When removing the outer blades, hold the hex shaped pulley hub with a 1 Vi-inch socket wrench to remove the hex nut holding the blade. A block of wood may be placed between housing and cutting edge of blade to assist in removal of hex nut securing blade. See figure 36. FIGURE 36. After replacing blades, grease the threaded end of the shaft to prevent rust buil...
