• Overlap a previously cleared path when necessary
(deep snow) so as not to overload the auger
housing with snow.
• NEVER drive the tractor into a snow bank. The
snow thrower attachment is NOT a dozer plow. The
lift linkage and/or the snow thrower drive system
can be damaged as a result of “plowing” with the
snow thrower attachment.
• Whenever possible, discharge snow downwind.
• When the tractor (with the snow thrower
attachment mounted) is not in use, use the lift lever
to lower the auger housing assembly to the ground
to relieve strain on the tractor’s front end between
uses.
• Do NOT attempt to remove ice or hard-packed
frozen snow.
• If the augers become jammed with a chunk of ice or
a foreign object, move the tractor’s lift lever into the
disengaged (BLADES STOP) position immediately
and turn off the tractor’s engine and remove the
ignition key. Examine the auger area thoroughly for
damage and do NOT operate the snow thrower
attachment until any damage is repaired.
IMPORTANT: The augers are secured to the spiral shaft
with two shear bolts and hex lock nuts. If you hit a hard
foreign object or an ice jam, the snow thrower is
designed so that the bolts may shear. Two replacement
shear bolts and hex lock nuts are provided for your
convenience. Store in a safe place until needed.
NEVER replace the auger shear bolts with standard
hex bolts. Any damage to the auger gearbox or other
components as a result of doing so will NOT be covered
by your snow thrower attachment’s warranty.
• Always use tire chains and rear wheel weights on
your tractor where extra traction is needed. Refer to
the table to the right to determine which kits will fit
your tractor (tire dimensions are stamped into the
sidewalls of your tractor’s tires).
• Use drift cutters to aid in displacing snow through
deep, drifted areas.
NOTE: None of the kits in the table are included as
standard equipment with snow thrower attachment
OEM-190-627. Call our Customer Support Department
as instructed on page 2 of this manual for availability
and information regarding these kits.
SECTION 7: ADJUSTMENTS
WARNING: Never attempt to make any
adjustments while the engine is running,
except where specified in the Operator’s
Manual. Place tractor on a firm and level
surface. Place the PTO in the disengaged
(OFF) position, set the parking brake, shut
engine off, and remove key to prevent
unintended starting
Lift Adjustment
If the lift index rod doesn’t latch securely or the pivot
release has too much slack in it, an adjustment can be
made as follows:
1. Loosen the upper hex nut a few turns, then tighten
the lower hex nut to shorten the cable length. Refer
to Figure 18.
2. Loosen the lower hex nut a few turns, then tighten
the upper hex nut to lengthen the cable. Refer to
Figure 18.
Skid Shoe Adjustment
The space between the shave plate and the ground can
be adjusted by repositioning the skid shoes found on
either side of the snow throwers auger housing. For
close snow removal, place skid shoes in the low
position. Use middle or high position when area to be
cleared is uneven. See Figure 19.
IMPORTANT: It is NOT recommended that this snow
thrower be operated on a gravel surface, as loose
stones can be easily picked up and thrown by the
machine. If you must operate on a gravel surface,
ALWAYS adjust the skid shoes into the HIGH position
to allow the shave plate maximum clearance.
