5.3 How to drive the mower WARNING While sitting, both feet should be firmly placed on the foot platform. Set the engine speed about a fourth of the way from idle. Release the parking brake. Now try moving the hand control levers, one at a time, very slightly, forward and backward. Check to see if the wheels move forward and backward according to the position of the levers. If not, check to see that the pump release valves are closed. The pump release valves are accessible by lifting the seat.
so the left caster wheel comes over and last should be the right caster wheel as the mower is twisting to the left (counterclockwise). The technique works the best if you try not to drive backwards at a near 90 degree angle to the curb but get all of the wheels to go over while the mower is moving at least a 45 degree angle to the curb. To drive off a curb, first try driving up onto it to make sure the curb is not too high.
lengthening the right-side rod) or the left side needs to go slower (by shortening the left-side rod). It is important that neither rod should be lengthened too far, as mentioned above.

It is normal to make these adjustments from time to time. 5.
6.2 Height-of-Cut Before adjusting the height-of-cut be sure the mower blades are off, and the rear tires have proper air pressure. Detent Pin Check for even tire wear. The height-of-cut can be adjusted the following way: • The cut height is set by allowing the foot lever to rest on a detent pin inserted into the height selection plates.
