1 To The Owner Thank You Thank you for purchasing an MTD Snow Thrower. It was carefully engineered to provide excellent performance when properly operated and maintained. Please read this entire manual prior to operating the equipment. It instructs you how to safely and easily set up, operate and maintain your machine. Please be sure that you, and any other persons who will operate the machine, carefully follow the recommended safety practices at all times.
Important Safe Operation Practices 2 WARNING! This symbol points out important safety instructions which, if not followed, could endanger the personal safety and/or property of yourself and others. Read and follow all instructions in this manual before attempting to operate this machine. Failure to comply with these instructions may result in personal injury. When you see this symbol.
Safe Handling of Gasoline 5. To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas. 6.
Clearing a Clogged Discharge Chute Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute. To clear the chute: 1. SHUT THE ENGINE OFF! 2. Wait 10 seconds to be sure the impeller blades have stopped rotating. 3. Always use a clean-out tool, not your hands. Maintenance & Storage 1. Never tamper with safety devices. Check their proper operation regularly.

3 Assembly & Set-Up Contents of Carton • One Snow Thrower • Two Replacement Auger Shear Pins • One Chute Assembly • One Snow Thrower Operator’s Manual • One Product Registration Card • One Chute Rod Assembly Handle 1. Place the shift lever in the forward-6 position. 2. Observe the lower rear area of the snow thrower to be sure both cables are aligned with roller guides before pivoting the handle upward. See Fig. 3-1.
2. Close the flange keepers to secure the chute assembly to the chute base. The flange keepers will click into place when properly secure. See Fig. 3-4. Set-Up NOTE: If the flange keepers will not easily click into place, use the palm of your hand to apply swift, firm pressure to the back of each. A pair of replacement auger shear pins and bow tie cotter pins are included with your snow thrower. See Fig. 3-10. Store them in a safe place until needed.
Tire Pressure Warning! Under any circumstance do not exceed manufacturer’s recommended psi. Equal tire pressure should be maintained at all times. Excessive pressure when seating beads may cause tire/rim assembly to burst with force sufficient to cause serious injury. Refer to sidewall of tire for recommended pressure. The tires are over-inflated for shipping purposes. Check the tire pressure before operating the snow thrower.
Auger Control Warning! Prior to operating your snow thrower, carefully read and follow all instructions below. Perform all adjustments to verify your snow thrower is operating safely and properly. Check the adjustment of the auger control as follows: 1. When the auger control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. 2. In a well-ventilated area, start the snow thrower engine.
4 Controls and Features Shift Lever Drive Control Auger Control Headlight Chute Directional Control Chute Assembly Clean Out Tool Augers Skid Shoe Figure 4-1 Snow thrower controls and features are described below and illustrated in Fig. 4-1. Shift Lever Skid Shoes Position the skid shoes based on surface conditions. Adjust upward for hard-packed snow. Adjust downward when operating on gravel or crushed rock surfaces.
Auger Control Chute Directional Control The chute directional control is located on left side of the snow thrower. To change the direction in which snow is thrown, rotate chute directional control. Chute Clean-Out Tool The auger control is located on the left handle. Squeeze the control grip against the handle to engage the augers and start snow throwing action. Release to stop. Drive Control / Auger Clutch Lock* The drive control is located on the right handle.
5 Operation Starting and Stopping the Engine Refer to the Engine Operator’s Manual packed with your snow thrower for instructions on starting and stopping the engine. To Engage Drive 1. With the throttle control in the Fast (rabbit) position, move shift lever into one of the six forward (F) positions or two reverse (R) positions. Select a speed appropriate for the snow conditions and a pace you’re comfortable with. 2. Squeeze the drive control against the handle the snow thrower will move.
6 Maintenance & Adjustments Maintenance Lubrication Engine Gear Shaft Refer to the Engine Operator’s Manual. The gear (hex) shaft should be lubricated at least once a season or after every twenty-five (25) hours of operation. Shave Plate and Skid Shoes 1. Allow the engine to run until it is out of fuel. 2. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. NOTE: Deluxe skid shoes (on select models) have two wear edges.
Auger Shaft Shift Cable At least once a season, remove the shear pins from the auger shaft. Spray lubricant inside the shaft and around the spacers and the flange bearings found at either end of the shaft. See Fig. 6-3. If the full range of speeds (forward and reverse) cannot be achieved, adjust the shift cable as follows: 1. Place the shift lever in the fastest forward speed position. 2. Loosen the hex nut on the shift cable index bracket. See Fig. 6-5.
Drive Control Off-Season Storage When the drive control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. If the snow thrower will not be used for 30 days or longer, follow the storage instructions below. 1. Run the engine until the fuel tank is empty and it stops due to lack of fuel. Do not attempt to pour fuel from the engine. 2. Lubricate the machine as instructed earlier in this section.
7 Service Belt Replacement 4. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. Auger Belt 5. Remove the frame cover from the underside of the snow thrower by removing the self-tapping screws which secure it. See Fig. 7-3. To remove and replace your snow thrower’s auger belt, proceed as follows: 1. Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine. 2.
7. Remove the belt from around the auger pulley, and slip the belt between the support bracket and the auger pulley. See Fig. 7-5. Drive Belt To remove and replace your snow thrower’s drive belt, proceed as follows: 1. To prevent spillage, remove all fuel from tank by running engine until it stops. Do not attempt to pour fuel from the engine. 2. Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. Refer to Fig. 7-1. 3. Remove the belt as follows. See Fig.
6. Back out the stop bolt to increase the clearance between the friction wheel disc and friction wheel. See Fig. 7-7. Friction Wheel Removal If the snow thrower fails to drive with the drive control engaged, and performing the drive control cable adjustment fails to correct the problem, the friction wheel may need to be replaced. Follow the instructions below. Examine the friction wheel for signs of wear or cracking and replace if necessary: 1. Allow the engine to run until it is out of fuel.
5. Carefully remove the hex nut which secures the hex shaft to the snow thrower frame and lightly tap the shaft’s end to dislodge the ball bearing from the right side of the frame. See Fig. 7-9. NOTE: Be careful not to damage the threads on the shaft. Follow the previous steps in reverse order to reassemble components. If you’re disassembling the friction wheel and replacing only the rubber ring, proceed as follows: 1. Figure 7-11 Figure 7-9 6.
8 Troubleshooting Problem Engine fails to start Cause Remedy 1. Choke not in CHOKE position. 1. Move choke to CHOKE position. 2. Spark plug wire disconnected. 2. Connect wire to spark plug. 3. Fuel tank empty or stale fuel. 3. Fill tank with clean, fresh gasoline. 4. Engine not primed. 4. Prime engine as instructed in the Operation section. 5. Faulty spark plug. 5. Clean, adjust gap, or replace. 6. Key not in ignition on engine. 6. Insert key fully into the switch. 1.
