Feed snow to the impeller fan at the center of the housing. STARTING Use the end of assembly checklist to verify that all instructions have been properly completed. Make sure the skid shoes are adjusted to maintain adequate ground clearance between the snow thrower and the type of surface to be cleared. The skid shoes are factory adjusted for clearing a smooth surface. (Refer to the Service and Adjustments section in this manual.) Make sure the tractor engine has the correct oil for winter operation. Refer to your tractor owner's manual. • 13 START YOUR SNOW THROWER The tractor should be sitting with the engine running at full throttle. Pull the attachment clutch switch out to the engaged position, starting the snow thrower before starting the tractor in motion. HOW • TO TO STOP YOUR SNOW THROWER To stop the snow thrower, push in the attachment clutch switch on the tractor. Refer to the Operation section in your tractor owner's manual. HOW TO USE YOUR SNOW THROWER & CAUTION: Never direct discharge towards bystanders or windows. Do not allow anyone in front of unit. CONTROLLING • • • SNOW DISCHARGE To control the direction snow is thrown, the discharge chute has 180 degrees of rotation. Turn the crank rod clockwise to rotate the chute to the right. Turn the crank rod counterclockwise to rotate the chute to the left. To control the distance snow is thrown, the upper section of the discharge chute pivots up and down. Push forward on the chute tilt handle to pivot the chute down, decreasing the distance snow is thrown. Pull back on the handle to pivot the chute up, increasing the distance snow is thrown. • & RAISING AND LOWERING • To raise, push down on the lift handle until the snow thrower locks in the raised transport position. • To lower, push down slightly on the lift handle and pull the trigger. With the trigger pulled, slowly lower the snow thrower until it reaches the ground. & OPERATING CAUTION: Do not operate the snow thrower without the rear weight attached to the tractor to provide extra traction and stability. • • REMOVING SNOW • • • Snow removal conditions vary greatly from light fluffy snowfall to wet heavy snow. Operating instructions must be flexible to fit the conditions encountered. The operator must adapt the lawn tractor and snow thrower to depth of snow, wind direction, temperature and surface conditions. • • • In extremely deep snow, raise the snow thrower from the ground to remove the top layer and drive forward only until the tractors front tires reach the uncleared bottom layer of snow. Depress the tractor's clutch-brake pedal and allow the spiral auger to clear the snow. Reverse the tractor and lower the snow thrower to the ground. Drive the tractor forward until the snow again becomes too deep. Repeating this process into and out of drifts will eventually clear even the deepest of snow piles. If the snow thrower becomes clogged with snow or jammed with a foreign object, disengage the snow thrower immediately and shut off the tractor engine. Unclog the snow thrower before resuming operation. • Before beginning operation, thoroughly inspect the area of operation and remove all door mats, sleds, boards, wires and other foreign objects. The spiral auger speed is directly related to engine speed. For maximum snow removal and discharge, maintain high engine r.p.m. (full throttle). It is advisable to operate the lawn tractor at a slow ground speed (1 st gear) for safe and efficient snow removal. In deep, drifted or banked snow it will be necessary to use full throttle and a slow ground speed (1st gear). Drive forward into the snow, depress the tractor's clutch-brake pedal and allow the spiral auger to clear the snow. Repeat this method until a path is cleared. On the second pass, overlap the first enough to allow the snow thrower to handle the snow without repeated stopping and starting of forward motion. 14 DANGER: Shut off engine and disengage snow thrower before unclogging discharge chute. Unclog using a wooden stick, not your hands. TIPS Discharge snow down wind whenever possible. To help prevent snow from sticking to the snow thrower, allow the snow thrower to reach outdoor temperature before using it. A light coat of wax may also be applied to the inside surface of the snow thrower housing and discharge chute. Use tire chains to improve traction. Use rear wheel weights to improve traction. Before the first snowfall, remove all stones, sticks and other objects which could become hidden by the snow. Permanent obstacles should be marked for visibility. Overlap each pass slightly to assure complete snow removal. CUSTOMER • RESPONSIBILITIES Read and follow the maintenance MAINTENANCE schedule and the maintenance procedures listed in this section.

Before storing at the end of each season rinse out the auger and impeller housing. Allow to dry thoroughly. Before storing at the end of the season, paint any exposed metal surfaces to protect from rust. OIL FIGURE 21 15 CAUTION: Before servicing or adjusting the snow thrower, shut off the engine, remove the spark plug wire(s), set the parking brake and remove the key from the tractor ignition. & REPLACING • • • • • • • • • RELEASE • • BELT • • ADJUSTMENT If the lift rod does not lock the snow thrower securely in the transport position, loosen the upper hex nut on the lift bracket a few turns and tighten the lower hex nut. See figure 10 on page 8. If the lift rod fails to unlock completely to lower the snow thrower to the ground, loosen the lower hex nut on the lift bracket a few turns and tighten the upper hex nut. Refer to figure 10 on page 8. SPIRAL • CABLE SHOE, LEVELING • • AUGERS The spiral augers are secured to the auger shaft with two shear bolts and hex lock nuts. If you hit a foreign object or if ice jams the augers, the snow thrower is designed so that the bolts will shear. If the augers will not turn, check to see if the shear bolts have sheared. See figure 22. Two replacement shear bolts and hex lock nuts have been provided with the snow thrower. For future use order part number 710-0891 shear bolt and number 43064 hex lock nut. l WOOD BLOCK ! / SCRAPER PLATE ADJUSTMENT The skid shoes regulate the distance the scraper plate is raised above the plowing surface. They are mounted on each side of the spiral auger housing. The leveling shoes help maintain the snow thrower in a level position. They are mounted just behind the auger housing. When removing snow from a gravel driveway or an uneven surface, it is advisable to keep the scraper plate as high above the surface as possible to prevent possible damage to the spiral auger. On a smooth blacktop or concrete surface, keep the scraper plate as close to the surface as possible. To adjust the skid shoes, raise the snow thrower off the ground and place a wood block under each end of the scraper plate. Loosen the six hex nuts securing the skid shoes to the housing. Adjust the skid shoes up or down to the desired position and tighten the nuts securely. Both skid shoes should be the same height to keep the housing and the scraper plate level. See figure 23. The skid shoes may be turned to face either in or out. In order to obtain the lowest setting, where the scraper blade fully contacts the ground, the skid shoes must be facing out as shown in figure 23. Before adjusting the leveling shoes, make sure the skid shoes are properly adjusted. With the snow thrower in the lowered position, loosen the bolts which fasten the leveling shoes to the thrower and adjust the leveling shoes to solidly contact the ground. Retighten the bolts. See figure 23. LEVELING SHOE SHEAR BOLT AND HEX LOCK NUT SHOE (The snow thrower must be attached to the tractor for correct adjustment of the shoes.) Raise the snow thrower to the transport position. Release the spring tension on the drive belt idler. Release the spring tension on the auger belt idler. Remove the belt cover and loosen the belt keeper bracket (items 18 and 19 on page 18). Remove the auger belt from the clutch/idler assembly and from the spiral auger housing. Install new belt around top of auger drive pulley and underneath the two side idler pulleys. Twist the belt 1/4 turn to seat it in each idler pulley. Reinstall the belt cover and tighten the belt keeper bracket (items 18 and 19 on page 18). Assemble the belt onto the clutch/idler assembly as instructed for figure 18 on page 11. LIFT • AUGER SKID SKID SHOE FIGURE 23 FIGURE 22 16 SKID SHOE STORAGE RECOMMENDATIONS PARTS • Lower the snow thrower to the ground and remove it from the tractor. • • Clean the snow thrower thoroughly. Wash off any salt deposits which may have dried on the thrower and housing. Any bare metal that has become exposed should be painted or coated with a light oil to prevent rust. Store in a dry place. • • • REMOVING THE SPIRAL AUGER • HOUSING • • Raise the snow thrower to the transport position. Release the spring tension from the auger belt idler arm on the bottom of the clutch/idler assembly. • Remove the auger drive belt from the clutch/idler assembly. See figure 18 on page 11. • Lower the snow thrower to the ground. • Remove the attachment pin and pull the auger housing assembly off of the tractor. Refer to figure 15 on page 10. HINT: If the auger housing does not remove easily from the tractor, try placing 1" or 2" blocks of wood under the front skid shoes on the snow thrower. See the instructions for figure 15 on page 10. PROBLEM • TO REMOVE AT END OF SEASON Remove the "V" belt from the engine pulley and the clutch/idler assembly. See figure 16 on page 10. Remove the clutch/idler assembly. (The two hanger brackets and the two frame brackets should not create any interference with the mower deck and may be left attached to the tractor frame.) If a rear mounted attachment is to be used, remove the rear weight tray by removing the two bolts which fasten it to the tractor draw bar and by loosening the two bolts fastening the tray's brace arms to the tractor. Be sure to retighten the two bolts and nuts which fastened the brace arms to the tractor. See figure 19 on page 12. If a front mounted attachment is to be used, remove the side plates from the front of the tractor. Be sure to reassemble the removed bolts and nuts to the tractor frame. See figures 1 and 2 on page 6. CAUSE CORRECTION Spiral augers stop turning 1. Upper or lower V belt too loose 2. Upper or lower V belt broken 3. Shear bolts are sheared. 1.
