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
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.
!
WARNING
Some tractors are equipped with multispeed PTO ranges. Be
certain your tractor’s PTO is set for 540 rpm.
Refer to Figure 3-1 on page 14:
1. Park tractor on a level surface. Slowly engage tractor
3-point lift lever to raise Snow Blower until gearbox
input shaft is in line and level with tractor PTO shaft.
2. Place gear selector in park, set park brake, shut
tractor off, and remove switch key.
3. Support Snow Blower at this height with support
jacks or blocks to keep unit from drifting down.
4. Remove rubber protective sleeve (#7) from gearbox
input shaft and discard.
5. Unsnap one end of both access doors (#8) and
rotate doors open.
6. Slide shearbolt end of driveline (#9) onto gearbox
input shaft until hole in driveline yoke aligns with
groove in gearbox shaft. Insert 1/2"-13 x 3 1/2" GR2
cap screw (#3) and secure with hex nut (#4) and jam
nut (#5). Draw hex nut (#4) up snug (Do not tighten)
and then tighten jam nut (#5) against hex nut (#4).
IMPORTANT:
Do not use a PTO adaptor with a
Quick-Hitch. 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
on page 34.
IMPORTANT:
The tractor’s PTO shaft and Snow
Blower gearbox shaft must be aligned and level with
each other during installation of driveline.
7. Push/pull on driveline yoke to be sure it is securely
fastened to the gearbox shaft.
8. Rotate access doors (#8) closed and snap in place.
9. Pull back on driveline yoke collar and push driveline
yoke onto the tractor PTO shaft. Release pull collar
and continue to push driveline yoke forward until pull
collar locks in place.
10. Move driveline yoke back and forth several times to
make sure yoke is locked in place. If driveline yoke
will not lock in place, skip to
on this page.
11. Attach safety chain (#1A) to Snow Blower frame or
gearbox cone. Re-latch safety chain to the inner
driveline shield.
12. Attach safety chain (#1B) to the tractor frame.
Re-latch safety chain to the outer driveline shield.
13. Continue with
.
Check Driveline Collapsible Length
1. Make sure driveline is properly installed and level
before checking driveline collapsible length. (Refer
instructions on page 15.)
Refer to Figure 3-3 on page 16:
2. With driveline level, measure (
“B”
dimension) back
from universal joint shield to end of outer driveline
shield as shown in Figure 3-3. If measurement is less
than 1", then shorten driveline using instructions
provided below.
Shorten Driveline
Refer to Figure 3-3 on page 16:
Be sure to check driveline collapsed length first. If
required, shorten driveline.
1. Un-hook driveline and safety chain from tractor PTO
shaft. Pull outer and inner drivelines apart.
2. Reattach outer driveline to tractor PTO shaft. Pull on
inner and outer driveline yokes to be sure universal
joints are properly secured.
IMPORTANT:
Two small safety chains are supplied
with the driveline. One must be attached to the inner
driveline shield and Snow Blower frame or gearbox
cone shield. The other chain must be attached to the
outer driveline shield and tractor frame. This will
keep driveline shields from rotating while implement
is operating.
IMPORTANT:
A driveline that is too long can bottom
out causing structural damage to the tractor and
Snow Blower. Always check driveline collapsed
length during initial setup, when connecting to a
different tractor, and when alternating between a
Quick-Hitch and a standard 3-point hitch. More than
one driveline may be required to fit all applications.
