The side shaft chain drive (PTO input shaft to the side line shaft drive sprocket, figure 13) is automatically tensioned by a spring-loaded idler nylon roller. The extension spring should extend 2" from its neutral 5" total length.

Manual adjustment for the automatic tensioning idler, nylon roller assembly is located at the right rear of the spreader’s front bearing mounting plate.

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 1/8-3/8” clearance between material guides and spinner teeth, figure 12. 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.

SHEAR ARM MATERIAL GUIDE ADJUSTMENT

Adjustment for the 1/8-3/8” 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 1/8-3/8” clearance retighten the jam nut to hold the material guide in place. Once recommended clearance is ob-

CLEARANCE

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 ½-13 x 3 ½” grade 5 replacement machine bolts are stored under the rear shield. For replacement install with ½” flat washer on top of shear eye and on bottom of block and tighten nylon locknut firmly.
