After the harvesting season, proper maintenance of the harvester is essential to ensure its longevity and performance for the next season. The primary task involves thoroughly cleaning the machine, removing sludge, dust, grass clippings, and any accumulated grass wrap that may have built up during operation. All drive belts should be removed, cleaned, and fully lubricated to prevent deterioration. For backpack models, the working components are detached from the tractor and maintained according to the tractor’s manual. The working parts should be stored on a flat surface, using a level support pad to avoid uneven stress. In areas where paint has peeled off, it's recommended to repaint or apply waste oil and grease to protect the metal surfaces.
Worn or damaged parts must be replaced promptly to avoid further damage. Belts should be taken off and either hung on the wall or laid flat on a board to maintain their shape. Self-propelled models follow similar procedures, but also require draining the engine cooling water, cleaning the radiator, and washing out the air filter. It's important to check and top up all oils, including engine oil, hydraulic fluid, and other lubricants, replacing them if they are contaminated or low. Each control joystick should be loosened, the frame supported, and the rubber tracks lifted off the ground to prevent deformation.
The harvester should be stored indoors on a dry, well-ventilated floor, away from fire hazards, oil, and chemicals. Regular checks of the engine are necessary, and a small amount of lubricating oil should be injected into the combustion chamber to keep internal components properly lubricated. Turning the crankshaft several times will help distribute the oil evenly within the cylinders.
Lubrication plays a key role in maintaining the efficiency and lifespan of the harvester. By applying oil or grease to moving parts, friction is reduced, which in turn minimizes wear and tear. This process helps ensure smooth operation and prolongs the life of critical components. While the specific lubrication points may vary slightly between different types of harvesters, the general approach remains consistent across models. Proper lubrication not only improves performance but also reduces the likelihood of breakdowns, making it an essential part of post-season care.
