Features & Controls C CONTROL FUNCTIONS D B The information below briefly describes the function of individual controls. Operating the tractor and attachment requires the combined use of these controls and additional controls whose operation is described in the tractor Operator’s Manual. A E F Please take a moment and familiarize yourself with the name, location, and function of these controls so that you will better understand the safety and operating instructions provided in this manual. Figure 1.
General Operating Instructions WARNING WARNING Perform the Safety System Interlock test found in your tractor Operator’s Manual. If tractor does not pass the test, do not operate the tractor. See your authorized dealer. Under no circumstances should you attempt to defeat the safety system. If auger does not start and stop when engaging/disengaging electric clutch, see your authorized dealer. Under no circumstances should you attempt to defeat the safety system.
General Operating Instructions Snow Removal Suggestions • Determine the best snow removal pattern before beginning. • Wind direction is an important factor to consider. Rotate the spout to discharge snow downwind. • Plan the pattern so that you avoid throwing snow on cleared areas and on yourself as you are operating. • When land contour permits, it is best to travel in the longest direction to minimize turning.
Maintenance WARNING General Lubrication Lubricate the snowthrower as shown in Figure 2. Where an oil can is shown use 30 weight oil. Where a grease gun is shown, use lithium grease. To avoid serious injury, perform maintenance on the unit only when the engine is stopped, parking brake is set and all moving parts have stopped. Always remove the ignition key before beginning maintenance or adjustments to prevent accidental starting of the engine.
Maintenance Inspect, Adjust, & Lubricate Drive Chain See Figure 3. D F G 1. Remove the two flange nuts (A) and chain guard (B). G H 2. Check the chain. Replace chain if worn or damaged. 3. There should be no slack in the chain, and the sprockets (D and E) should be aligned. The drive shaft (H) should be parallel with the auger housing. If adjustment is required proceed with steps 4 - 7. E C 4. Loosen the adjustment nuts (F). 5.
Troubleshooting, Adjustments, & Service TROUBLESHOOTING WARNING While normal care and regular maintenance will extend the life of your equipment, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly. To avoid serious injury, perform maintenance on the tractor or mower only when the engine is stopped and the parking brake engaged.
Troubleshooting, Adjustments, & Service Drive Chain Adjustment See Inspect, Adjust & Lubricate Drive Chain in the MAINTENANCE Section. Skid Shoe Adjustment Loosen Nuts to Adjust On smooth surfaces such as concrete or asphalt, the scraper bar should scrape the surface. On surfaces such as gravel, the scraper bar should be set high enough so that it will not pick up debris. Figure 5. Adjusting Skid Shoes 1. Loosen the nuts securing the skid shoes (see Figure 5). 2.
Troubleshooting, Adjustments, & Service Lift Rod Adjustment C In the fully raised position the attachment should be 4”-5” off the ground. In the fully lowered position, the lift rod should compress the spring creating downward pressure on the blade. B A NOTE: Always adjust the lift height before and after adjusting the downward pressure. LIFT HEIGHT ADJUSTMENT 1. Fully raise the attachment lift. The snowthrower should be approximately 4”-5” off the ground. If not, go to step 2. 2.
Troubleshooting, Adjustments, & Service Belt Tension Adjustment See Figure 8. 1. With the snowthrower drive belt installed, trunnion (A) should be between marks (G) on spring tension bracket (B) for correct belt tension. 2. Turn belt tension handle (C) to move trunnion forward or rearward until it is between marks. 3. If trunnion cannot be placed between marks, loosen capscrew (D) and reposition idler pulley (E) as necessary. The pivot bracket (F) should be perpendicular to the hitch.
