Adjustments
Lift Rod
See Figure 17. For initial setting, place front set collar
(A)one inch from rod guide with blade fully lowered. Place rear set collar (B) against spring (C). Tighten the setscrews in the two set collars.To adjust, perform the following:
1.Fully raise the blade by pulling back on the tractor lift lever. Measure distance between scraper bar and ground. If it measures approximately six inch- es, it is properly adjusted. If not, proceed to step 2.
2.Lower the blade. Loosen the setscrew in the front set collar. move the set collar back to increase ground clearance, forward to decrease ground clearance. Tighten the setscrew. Recheck the measurement.
NOTE: Different ground contours may require differ- ent adjustments. Moving the rear set collar toward rear will allow the blade to follow a rolling contour. Lower the blade to adjust the rear set collar. The far- ther back the rear set collar is positioned, the more the blade will float. Moving the rear set collar toward the front will increase down pressure.

Skid Shoe Adjustment
Slotted holes are provided to permit adjustment of the shoe assemblies for raising and lowering the blade to various working heights (see Figure 18).
When cleaning snow from gravel or earth drives or walks, the shoe assemblies should be lowered fully to prevent blade contact with gravel or ground. When cleaning smooth hard surfaces like concrete, the shoe assemblies are normally placed fully up to allow the blade to scrape the surface.
To adjust the skid, raise the blade off the ground and block with a piece of wood. Loosen the bolts (B, Figure 18) and move the skid shoes (A) up or down to desired height. Tighten the bolts securely.
