I l Fig. 6 Fig. 9 4 , 5. Attach the upper end of the clutch rod to the clutch rod pivot lever located on the left side of the tractor transmission. See figure 10. The projecting pin on the rod socket assembly is to be inserted into the hole in the clutch rod pivot lever and held in place by a hair pin cotter. Adjus t the tension on the “V ” belt by loosening the set screw and sliding -collar “A ” in or out while the clutch lever is in disengaged position. Retighten the set screw and engage the clutch. Belt tension will be correct when approximately 1/4 ” clearance is. visible between collar “B ” and the end of the rod socket assembly when the clutch is engaged. Avoid excessive belt tension as it will only cause premature belt failure. Operation Operation of the rotor is controlled by the position of the clutch lever located on the left handle of the tractor. To operate the rotor, push the lever forward and up to the disengaged position and start the tractor engine. Be sure that the tractor transmission is in neutral position before starting the engine. Pull the clutch lever back and downward to the, engaged position and the rotor will operate as long as the tractor engine is running. Bear in mind that the rotor will be revolving as long as the clutch is engaged and the tractor engine is running. Exercise caution at all times, and attempt to remove ice or snow from the rotor housing ordischarge spout unless the clutch is disengaged and the tractor engine is stopped. The skid shoes on each side of the rotor housing are adjustable either up or down to suit the surface over which the plow is to be operated. For a smooth surface, loosen the nuts and set the shoes so that the lower edge of the rotor housing rides on the surface. For use over an uneven or rough surface, adjust the shoes for maximum lift. When using the plow, set the discharge spout so that the snow will be thrown with the wind and never into the wind. Throwing snow into the wind is apt to be a source of discomfort to the operator. To alter th direction of discharge, rotate the spout by means of the adjusting handle. The angle of discharge may be altered by loosening the wing nut on the discharge spout extension adjusting rod and moving the extension to the desired position. Retighten the nut. When operating the plow through excessively heavy drifts of snow, depress the tractor handles and raise the plow while taking the first pass through the drift. Then lower the plow and go through the drift again.
