How-To
very effective approach is to follow the crop’ s path through the machine— from the header all the way to the grain tank. This often prevents important components from being overlooked.
Modern combines also rely heavily on electronic systems. Yield monitors, moisture sensors, loss monitors, cameras and onboard diagnostic systems should all be checked as part of the readiness regimen. In addition, it is highly recommended that a short test run be performed. This is a very useful way to uncover unusual noises, warning codes or performance issues while there is still time to make repairs and order parts.
Don’ t Forget the Supporting Cast
The combine may be the star of the show, but even a perfectly prepared combine can spend too much time sitting still if the supporting equipment isn’ t ready to go. Grain carts, augers, conveyors and trucks deserve the same attention as the combine itself. Tires, wheel bearings, brakes, lights and hydraulics should be carefully checked. Inspect augers for worn flighting, damaged tubes and failing bearings.
As equipment continues to grow in size and capacity, the entire harvest system must work together efficiently. A bottleneck anywhere in the flow chain can slow progress. This can be especially frustrating when conditions are ideal and every hour counts.
Don’ t Overlook Grain Storage
Preparing grain bins may not be as fun or interesting as servicing a combine, but it can have just as much impact on profitability. So, it’ s critical to remove old grain, fines and debris from bins, unload systems and aeration ducts. Extension specialists consistently identify sanitation as one of the most important defenses against insects and grain spoilage.
Inspect bin walls, roofs, ladders, doors, motors, fans, heaters and electrical systems. Run aeration fans to verify proper airflow and check temperature monitoring systems to ensure they are functioning properly.
The goal is to protect grain quality after it leaves the field. Problems discovered after bins are full are usually much more difficult— and expensive— to correct.
Keep Common Replacement Parts on Hand
Nearly every grower has a story to tell about losing valuable time while waiting for a relatively inexpensive replacement part.
Belts, bearings, chains, sickle sections, hydraulic hoses, filters and common fasteners are all worth adding to the preseason inventory items. Reviewing repairs from previous seasons can help identify which parts are most likely to be needed again. Of course, no one can stock every possible replacement component, but keeping commonly used items on hand can turn what would have been a day-long delay into a quick repair.
Make Safety Part of the Readiness Plan
Long days in the field, along with fatigue and the pressure to keep the process moving, can create ideal conditions for accidents to happen. Before harvest begins, do your due diligence to ensure that all safety precautions are taken. Inspect fire extinguishers, verify that lighting systems and reflective
