Commercial Snowblower SNOWBLOWERS This manual is for both Commercial Hydraulic Snowblowers and Commercial PTO Drive Snowblowers. The hydraulic models come in 60”, 74” and 84” widths. The PTO drive model is only available in an 84” width. Hydraulic models come with four different motor series. Hydraulic output on the equipment running the Snowblower must match the requirement for each motor series for the Snowblower to work. The hitch is a skid steer fixed type of quick hitch.

Commercial Snowblower OPERATING INSTRUCTIONS 1. HYDRAULIC DRIVE: All snowblower hydraulic blocks are set at the factory for a 2800 - 3000 psi system. Refer to the section on the hydraulic control block if your system does not fall into this range. 2. ALL: Depth of the cut can be partially controlled by tilting the snowblower forward or backward. 3. PTO DRIVE: Adjust the top link of the tractor hitch so the snowblower is just slightly tilted back when resting on the ground.
Commercial Snowblower OPERATING INSTRUCTIONS – cont’d. 10. ALL: Chain tension on auger chain should be set at 3/8” to 1/2” slack. 11. LUBRICATION: a) ALL: The gear teeth on the chute control should be periodically lubricated with gun grease. b) PTO DRIVE: PTO shaft universal joints and square shaft slide should be periodically lubricated with a grease gun. c) ALL: Regularly oiling the chain will significantly increase the life of the chain.
Commercial Snowblower HYDRAULIC CONTROL BLOCK NON-STALLING-FAN FEATURE: The Hydraulic Snowblower has a unique modulating element that keeps the blower fan from stalling in an overloaded condition. This is accomplished by starving the hydraulic flow to the front auger motor (which then stops feeding the fan) and diverts all of the flow (and energy) to the main fan motor. As the fan clears itself, and the pressure drops, the auger again begins feeding according to load.

Commercial Snowblower ASSEMBLY INSTRUCTIONS 1. SPOUT ASSEMBLY FOR ALL SNOWBLOWERS: Remove two of the grooved spout rollers to mount the discharge spout. Replace the two rollers to hold spout in place. Install the 2 ½” x 8” cylinder on the spout using the pins supplied. 2. HYDRAULIC DRIVE: The 62” long hydraulic lines (#14) for the spout deflector cylinder should be connected to the two ports on the hydraulic block labeled C1 and C2 (see section on hydraulic control block for block drawing).
Commercial Snowblower ASSEMBLY INSTRUCTIONS – cont’d. b) Using tape or a bright colored marking pen, mark on the outer shields the position where the shaft is completely pushed together and the position where you have a 4” overlap. Watch these marks when moving the blower through all possible operating angles to see that the PTO shaft stays within this range. c) With the engine on the tractor shut off, attach the PTO shaft. The tractor end has a standard 6-spline end with a spring loaded locking collar.
Commercial Snowblower ASSEMBLY INSTRUCTIONS – cont’d. 4. PTO SHIELD: All PTO snowblowers are supplied with a PTO shield (#18). To install, remove the two rear bolts at the top of the gearbox (#34). Bolt the PTO shield to the gearbox by the hinges using these same bolts. A utility spring (#68) keeps the shield in place. Hook one end of the spring in the hole in the shield and the other end to the hole in the brace under the gearbox. CAUTION: Do not run the snowblower without this shield in place.
