In order to extend the service life of farm machinery, it's essential to implement the following "four preventions" during the off-season. Proper maintenance not only ensures the equipment is ready for the next farming season but also saves money in the long run by reducing repair costs and downtime.
After completing field operations, it's important to thoroughly clean the machinery. Remove all dirt, crop residues, seeds, fertilizers, and pesticides from the working parts. If necessary, use water or oil to clean hard-to-reach areas. This prevents corrosion and ensures that no leftover materials cause damage during storage.
Next, clean all lubricated components and reapply grease or oil as needed. For parts like plowshares, plow walls, openers, and spade shovels, make sure to wipe them with a protective oil after cleaning. Using stickers or plastic covers can further reduce their exposure to air and moisture, helping to prevent rust.
High-quality tools should be stored in a cool, dry, and well-ventilated area. Simpler implements such as plows, rakes, and hoes can be stored outdoors, but they should be placed on elevated, dry ground away from direct sunlight. Consider using a shelter or scaffolding to protect them. Any part that touches the ground should be supported with wood or bricks, and any flaked paint should be repainted to maintain protection.
Wooden parts are prone to decay, cracking, and warping due to microorganisms, moisture, wind, and sun exposure. To protect them, coat the exterior with paint and store them in a dry location. This helps preserve their structural integrity and prolongs their lifespan.
Rubber and plastic components are vulnerable to aging caused by oxygen and ultraviolet light. Their elasticity can degrade, leading to cracks or breaks. When storing rubber parts, apply a thin layer of hot paraffin oil to the surface. Keep them indoors on a shelf, covered with paper, in a dry and well-ventilated space—never in direct sunlight.
Lastly, parts like springs, drive belts, long shanks, and tires can become permanently deformed if left under stress or improperly stored. Ensure proper support is provided under the storage rack so that tires don’t bear weight. Loosen any tensioned springs or pressure points on the machine. Remove drive belts and store them indoors. Parts like long knife bars should be laid flat or hung vertically, while items like tires and seed tubes should be stored separately to avoid crushing or deformation.
By following these steps, farmers can ensure their equipment remains in excellent condition, ready for use when the next planting season begins.
