500 & 600 SNOWBLOWER ASSEMBLY INSTRUCTIONS – cont’d.
4.Hydraulic Control Assembly: (Option)
a)Bolt the hydraulic swivel assembly (#21) to the back of the fan housing on the left side using ½” x 1 ¼” hex bolts, lock washers and hex nuts.
b)Bolt the cylinder mounting bracket (#23) to the back of the fan housing on the right side using the same size hex bolts.
c)Turn the spout forward and the center of the swivel arm in line with the spout center. With the spout and swivel arm in this position, wrap the cable (#22) around the spout and clamp to both ends of the swivel arm and to the bracket welded to the bottom of the spout using 3/16" cable clamps (#20).
d)Use a standard 8" stroke cylinder (20 ¼” min., 28 ¼” max. pin centers).
5.Mounting Blower on Tractor:
a)Mount the blower on a tractor with a category 1 hitch.
b)Using tape or a bright colored marking pen, mark on the outer shield 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.
c)With the engine on the tractor shut off, attach the PTO shaft. The tractor end has a standard
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.
d)Check that the PTO shaft does not bottom or separate with the blower 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
