    This manual is for model #740 & #840 snowblowers with an open gear gearbox and for model #840G snowblower, which has a sealed oil bath gearbox. When ordering parts, specify model number and serial number. The snowblower is the push type and will mount to a tractor with a 540 rpm PTO.

  • Page 6: Operating Instructions

    OPERATING INSTRUCTIONS Do not operate the blower in the fully raised position. The three-point hitch on some tractors raises high enough to cause the PTO shaft to bind. This can cause damage to the PTO shaft and/or to the hitch and pins. NOTE: PTO shaft angle should not exceed 20 degrees for optimum performance and life.
  • Page 7 OPERATING INSTRUCTIONS – cont’d. Periodically check all bolts for tightness. The bolt holding on the fan and the bearing bolts are of particular importance. Danger: Always stop blower for servicing or unplugging. The PTO should be disengaged before dismounting from the tractor. CAUTION: Always check to see that both ends of the PTO shaft are securely attached as per instructions every time you are preparing to use the snowblower.
