OPERATION UNLOADING & SPREADING Packed Material To unload and spread packed material and prevent unnecessary stress on the drive line components, observe the following guidelines: 1. Make sure the auger is completely lowered. 2. Engage the tractor PTO at as low an RPM as possible. Then, slowly bring the PTO up to the rated RPM. 3. Raise the discharge gate until it is about 1/3 open. 4. Select the desired tractor gear and begin spreading. To achieve the desired coverage, adjust the discharge gate and/or travel speed. 5. When spreading material which is susceptible to bridging, the auger should be cycled up and down, frequently, to provide a more consistent feeding of material into the expeller. NOTE: Do NOT exceed the rated 540 or 1000 RPM operating speed of your particular model of Manure Spreader.
OVERLOAD PROTECTION When shear bolt failure is detected, stop all operation and follow the EMERGENCY SHUTDOWN PROCEDURE. Shear bolts are used to provide overload protection in two areas on the 2320 and 2326 Manure Spreaders.
Expeller Drive The discharge expeller sprocket has two ¼” x 1-1/2” grade 8 shear bolts with locknuts. Additional shear bolts are stored on the expeller front bearing mount. The following are probable causes for discharge expeller shear bolt failure: 1. PTO is being engaged while RPM’s are too high. 2. A foreign object is present in the expeller. 3. Overfeeding of the expeller due to improper discharge gate adjustment. 4. Gate is being raised when spreading liquid material, before expeller is up to operating speed. Shields open for viewing
Auger Jackshaft The auger drive sprocket is secured to the auger jackshaft hubwith two 5/16” x 1-1/2” grade 8 shear bolts and locknuts. Additional shear bolts are stored in the chain tensioner bracket.
