Assembly - 740, 840 & 840G Snowblower
6. Hand Crank (Option)
- Fasten hand crank assembly (#5) using two 1/2" x 1-1/4" hex bolts, lock washers and hex
nuts.
- Thread cable (#7) through hole in hand crank to even lengths and wrap around the tube to
each side of the hole four turns in opposite directions.
- Turn spout to center forward position and clamp cable to cable anchor on far side of spout
using clamp (#84).
7. Mounting Snowblower on Tractor
- Mount the snowblower on a tractor with a Category 1 or Category 2 hitch.
- Using tape or 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.
- With the tractor engine shut off, attach the PTO shaft. The tractor end has a standard
6-spline end with a spring loaded locking collar. The snowblower end has a clamp-style
yoke with a 3/8" keyway. Slide the yoke onto the gearbox shaft with the 3/8" key supplied.
Lock the yoke in place with the 1/2" x 3" hex bolt and lock nut fitted through the groove
in the gearbox shaft. After tightening the bolt, insert and tighten the 3/8" socket set screw
supplied.
CAUTION
Always check to see that both ends of the PTO shaft are securely
attached every time the snowblower is used. This should always
be done with the tractor engine off.
- Check that the PTO shaft does not bottom out or separate with the snowblower in the
extreme high and low positions. Check to see which of the four different hitch positions
will allow you to keep about a 4" minimum overlap on the PTO shields without bottoming
out. This position varies between different tractor models because of the different lengths
of the three-point arms. If the PTO shaft is still too long with the hitch fully extended, the
PTO shaft will have to be cut shorter. Check for free movement of all parts in various raised
positions, particularly the PTO shaft.
