6 things that make your harvester crash

The power supply has a huge impact on how it works, especially when wet, with constant flow to the rotor or cylinder, Edgington explains. However, bars and chains are often overlooked during pre-season checks.

So make sure all blades are parallel to each other and not worn out. “A bent belt is an invitation to failure, as the belt can become loose, get stuck and even damage the loading chamber,” he warns.

When rotating the drive from the power box, make sure the chains are worn and have the correct tension. When they reach the full tension adjustment range, the chains must be replaced.

“Many practitioners do not seek contact with medical practitioners to make sure they are safe. Also check the chain guides and replace them if worn. By the way, check the wear on the top drive wheels and front drum bearings. "

2. Concave elements

All in all, checking the rotor or cylinder is a great job. If the preseason inspection fails, check the concave for round or bent rods, missing cables, foreign objects, or accumulated debris. Edgington insists that all hollow panels be removed and thoroughly cleaned before re-installation. “When reinstalling, make sure the drives are aligned,” he says. Finally, check the integrity of the lid seals so that they do not peel off the feed during threshing. Also check for wear on the whip face plates.

3. Non-woven fabric, screen elements.

One of the dirtiest jobs when preparing a combine for the season is removing vines and sieves, which is often avoided. After removing the apron and curtains, pay attention to general wear and tear, especially in the center of the front of the apron. This is where most of the debris and grain comes out of the separator. Examine the frames. Check the sides and corners for cracks and stress breaks. Cracks can be welded if necessary.

Then check the backlash of the fixing bolts and then tighten them to the torque specified in the instruction manual. “When replacing fasteners, use only bolts of the correct quality specified in the instructions. Your overall goal is to get a solid frame because you don't want the screen or filter to come off, ”says Edgington.

Look for bent or missing fingers during this test. Notice where the braid and shielding rods (wires) go over the frame and look for the elongated holes in the frame. Next, inspect the bulkhead and high performance check valves to ensure they are missing or damaged.

4. Cleaning the fan shoe.

One such seemingly indestructible item is a shoe-cleaning fan. “Today's fans shoot at high speed. A group of sludge sucked in by the fan can bend the blade, upsetting the working balance and possibly damaging the fan, ”Edgington warns. His advice is to remove the drive belt and start the fan, thinking about correct operation, listening to the noise of the bearings.

5. lifts

Remove the drive belts from both grain elevators so the chain can rotate. This way you can find worn out or missing blades and loose chains. Then check the chain tension and adjust if necessary. Check tension daily during harvest. A sure sign of a lack of tension can be seen in the pallets that dangle during operation, causing the grain to fall into the elevator.

“Beware of rolling noise when cornering in an elevator,” says Edgington.

6. Chipper

Worn blades not only cause strong adhesion (cutting) of the waste, but also cause the shredder to stretch, which consumes more energy. If new knives are required, the knife assembly must be replaced. Otherwise, the helicopter will be out of balance, which will lead to self-destruction of the entire device.

Spend more time studying the entire structure of the waste management system. Check the integrity and wear of the tail lift vanes as they are necessary to distribute the shredded material evenly.
