SPINNER MATERIAL GUIDES

Regularly inspect and adjust two spinner material guides located at both the left rear and right rear of the spreader. Create a 1/4-1/2” clearance between material guides and spinner teeth, figure 13. Maintain the recom- mended clearances for maximum spreading pattern. Adjust to prevent excessive manure build-up on mate- rial guide inner surfaces. Adjust to prevent manure chunks or foreign object lodging between material guides and spinner teeth.

NOTE: Excessive lodging can cause premature spinner tooth wear, “bent-over” or even breakage.

SPRING LOADED MATERIAL GUIDE ADJUSTMENT

Adjustments for the 1/4-1/2” clearance of each material guide to spinner tooth is made by tightening or loosen- ing the 1” nut on the material guide spring linkage shaft assembly. Tighten nut to increase clearance and loosen nut to decrease clearance between the material guides and spinner teeth. Once recommended clearance is ob- tained turn spinners over by hand in the direction by

CLEARANCE

which the spreader would turn to check clearance. Do not turn in the opposite direction as front chain tightener damage could occur.

SHEAR ARM MATERIAL GUIDE ADJUSTMENT

Adjustment for the1/4-1/2” clearance of each material guide to spinner tooth is made by loosening the jam nut on the linkage arm and turning the linkage arm to either move the guide in closer or out farther from the spinner teeth. After adjustment has been made for the 1/4-1/2” clearance retighten the jam nut to hold the material guide in place. Once recommended clearance is ob- tained turn spinners over by hand in the direction by which the spreader would turn to check clearance. Do not turn in the opposite direction as front chain tightener damage could occur. If foreign objects enter the spinner area the front pivot bolt on the shear arm is designed to shear. The extension spring will pull the material guide away from the spinner until the shear bolt is replaced. The ½-13x3” grade 5 replacement machine bolts are stored on the left side plate for the gearbox mount channel. For replacement install with ½” flat washer on top of shear eye and on bottom of block and tighten ny- lon locknut firmly.
