Driveline Installation
!
DANGER
Do not engage tractor PTO while hooking-up and unhooking
driveline or while someone is standing near the driveline. A
person’s body and/or clothing can become entangled in the
driveline resulting in serious injury or death.
!
DANGER
All guards must be installed and in good condition at all times
during operation.
!
WARNING
Do not use a PTO adapter. A PTO adapter will increase strain
on the tractor’s PTO shaft resulting in possible damage to
shaft and driveline. It will also defeat the purpose of the
tractor’s master shield and could cause bodily injury or death.
!
WARNING
Always disengage PTO, engage parking brake, shut tractor
engine off, remove switch key, and wait for PTO to come to a
complete stop before dismounting from tractor.
!
CAUTION
Some tractors are equipped with multispeed PTO ranges. Be
certain your tractor’s PTO is set for the correct speed:
• SBD Series are designed for 540 rpm rear PTO.
• SBDM Series are designed for 1000 rpm rear PTO.
IMPORTANT: Do not use a PTO adapter. A PTO
adapter will increase strain on the tractor’s PTO
shaft resulting in possible damage to shaft and
driveline.
IMPORTANT: An additional driveline may be
required if Snow Blower is to be used on more than
one tractor, especially if a Quick Hitch is used.
IMPORTANT: The driveline must be lubricated
before putting it into service. Refer to “Lubrication”
on page 35.
IMPORTANT: The tractor’s PTO shaft and Snow
Blower gearbox shaft must be aligned and level with
each other during installation of driveline.

IMPORTANT: Do not shorten driveline. Extend
Snow Blower 3-point hitch or add a quick hitch to
your tractor if driveline is too long to attach to your
tractor with gearbox shaft and PTO shaft in
alignment and level with each other. Refer to “Hitch
Adjustment” on page 22 for instructions on how to
extend the Snow Blower 3-point hitch.
