Pre-Operating Inspection
Before starting the grinder, a visual inspection is necessary. This includes checking for loose bolts, proper lubrication, and ensuring all safety features are in place. The machine should be on level ground, and unusual vibrations should be addressed immediately.
Machine Description and Controls
The H-1000 Tub Grinder is designed for grinding hay, grain, and crop residue. It features a rotating tub, electronic governor, rotor, and hammer assemblies. Operator controls include an electronic governor, hydraulic valves, and a PTO lever.
Electronic Governor
The governor has two modes: Engine (Auto) and Tub (Manual). The Engine mode adjusts tub speed based on engine load, optimizing efficiency. The Manual mode maintains a constant tub speed.
Rotor and Screens
The rotor is equipped with 64 swinging hammers. Proper maintenance of hammers and screens is essential for efficiency. Operators are cautioned to keep foreign objects away from the rotor to prevent damage.
Specifications and Recommendations
The document provides detailed specifications for the H-1000 Tub Grinder, including recommended screen sizes for different materials. For hay, use screens with 2” to 4” holes; for ear corn, 5/8” to 1”; for shelled corn, 3/4” dry and 5/8” high moisture; and for small grains, 1/4” to 3/8”. The size of the screen holes determines the coarseness of the grind.
Tub and Fins
The tub contains material above the rotor. Two tub fins are provided, with specific configurations for different bale types. For large round bales, use one fin in the upper position; for small bales or loose hay, use two fins in the lower position.
Slug Buster and Mill Grate
A slug buster or mill grate regulates material entering the rotor chamber. The slug buster is for dry hay, while the mill grate is for wet hay or tough grasses.
Conveyor and Valves
The discharge conveyor is controlled by a manual valve, with hydraulic oil supplied by the tractor. Different tractors require specific valve types: closed center for John Deere Series 60 and older, open center for others.
Machine Operation
Proper tractor setup is crucial to avoid damage. The document outlines steps for connecting and disconnecting the grinder to a tractor, emphasizing alignment and safety precautions.
Grinding Procedures
Materials should be placed directly into the tub, with specific methods for different materials like loose hay, wet or frozen hay, large round bales, crop residue, small grains, and ear corn. Special attachments are recommended for small grains and ear corn.
Shutdown and Storage
Normal and emergency shutdown procedures are detailed, highlighting the importance of waiting for all parts to stop moving before maintenance. Storage preparation includes lubrication checks, cleaning, and inspection.
Electronic Governor
The electronic governor controls the feed rate and tub speed, with modes for manual and automatic operation. Calibration steps ensure optimal performance, adjusting settings based on engine load and speed.
Transport
Instructions for setting up the grinder for road transport and returning it to operational status are provided, including folding and unfolding the conveyor.
Hammermill Maintenance
Regular visual inspections are crucial to identify excessive wear on internal parts such as rotor discs, rods, hammers, and screens. Enlarged holes in discs can lead to rod breakage. Bearings and mounting bolts should be checked to ensure stability and reduce vibration. Foreign objects must be kept away to prevent injury or damage. Hammers are designed for durability but should not be altered as it affects their properties. Periodic rotation of hammers is recommended to maximize lifespan.
Hammer Maintenance and Replacement
Before servicing, ensure the machine is shut down. Follow the hammer pattern diagram to avoid vibration issues. Replace hammers in pairs and ensure they are of equal weight. After replacement, check for unusual vibrations and address any issues before restarting.
Troubleshooting the Electronic Governor System
Ensure the fuse light is on to confirm power to the electronic governor. Check the tub mode operation by adjusting the tub limit knob and observing the speed lights. If issues persist, refer to the troubleshooting table. For engine mode, follow calibration instructions if tub mode functions correctly.
Electronic Governor Hardware Test
Test the governor with a voltmeter to ensure proper voltage output. Adjust the tub limit knob to check voltage changes. If the electronic system fails, manual override is possible by adjusting the electro-hydraulic valve.
General Troubleshooting
Refer to the troubleshooting section for common issues and solutions.
