Place wooden blocks under the tires to lift them off the ground, reducing the risk of flat spots and tire degradation. Ensure the storage location is secure and protected from vandalism or theft. Consider using wheel chocks or other security measures to prevent movement of the tractor.
Pay attention to the environment around the storage location. Avoid storing the tractor near areas with high humidity, chemical exposure, or rodent activity. Moisture can promote corrosion, while chemicals can damage paint and other surfaces. Rodents can chew on wires and hoses, causing significant damage to the tractor's systems. Consider using rodent repellent devices or baits to deter rodents from nesting near the tractor. Regularly inspect the storage area for signs of pests and take appropriate action to eliminate them.
Post-Storage Inspection and Startup
Before starting your John Deere T100 after a period of storage, a thorough inspection is essential to ensure its safe and reliable operation. Begin by checking all fluid levels, including engine oil, coolant, transmission fluid, and hydraulic fluid. Top up any fluids as necessary, using the recommended grades specified in your owner's manual. Inspect all hoses and belts for cracks, wear, or damage. Replace any damaged components before starting the engine.
Check the battery condition and terminals. Clean any corrosion from the terminals with a wire brush and apply a corrosion inhibitor. If the battery is weak or discharged, charge it before attempting to start the tractor. Consider using a battery maintainer during storage to keep the battery charged and in good condition. Inspect the tires for proper inflation and any signs of damage. Inflate the tires to the recommended pressure before operating the tractor.
Before starting the engine, prime the fuel system by cycling the ignition key or using the manual priming pump, if equipped. This ensures that fuel is present in the fuel lines and ready to be injected into the engine. Start the engine and allow it to idle for several minutes to warm up. Listen for any unusual noises or vibrations. Check all gauges and indicators to ensure they are functioning properly. Operate all controls, including the steering, brakes, and implements, to verify they are working as intended. If any issues are detected, address them before using the tractor for any significant work.
