Mounting Blower on Tractor | Buhler FK311 specification

500 & 600 Snowblower

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 6-spline end with a spring loaded locking collar. The snowblower end has a clamp-style yoke with a ¼” key way. Slide the yoke onto the gearbox shaft with the ¼” key supplied. Lock the yoke in place with the ½” 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.

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 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.
