Checking and Adjusting the Blade Level An alternate way to check this is to remove the mower housing and turn it over. Remove the blades and lay a straight edge on two blade saddles (Figure 59). It should lie flat. If not, either the spindle or the housing where the spindle mounts may be bent. 300-400-500 Series Garden Tractor (Excluding 5xi Series) The mower attachments used on these tractors all have the side-to-side level and the height of cut determined by the rear gage wheels (Figure 60). Figure 59 altbltrk.TIF Yet another way to check this with the blades attached is to align the blades (two blades at a time on three blade mowers), then run a string across the cutting tips of the blades. The string should be straight. If it is not, the blade or spindle could be bent. If the saddles or blades do not line up and the spindles are not bent, a shim between the spindle housing and the mower housing may help align them. Loosen the spindle to mower housing bolts and insert shim washers until the saddles are in line. Then if you used washers to shim the spindle housing, remove the bolt and reassemble through the washer to secure it. Figure 60 1380-09.TIF Adjusting Side-to-Side Level If the mower does not cut level side-to-side, check for a worn out gage wheel, a bent gage wheel support, or improperly tracking blades. Finding and correcting that should bring the side-to-side level back to normal. Adjusting Front-to-Rear Pitch The blade should be 1/8-1/4 inch (3.1-6.3mm) lower in front than in the rear. If it is not within specification, adjust the rear link. Turn the locknut on the link (Figure 61).To raise the front of the mower, turn the locknut clockwise. To lower, turn the locknut counterclockwise. Service Dealer's Guide to Great Quality of Cut 1. Link Figure 61 2. Locknut 345gtF2R.TIF 4 - 19
