Grain losses Losses of grain may have different reasons. Therefore, always determine first where the losses occur. Check combine for leakage losses.
Check whether grain is lost where working parts join, especially check auger troughs, elevators etc. Extra care should be taken to check the working parts for good fitting when combining small seeds. Repair all leaks as necessary. Losses that are caused by overripe crops or poor weather conditions must not be taken for combine losses. Grain losses that are due to combining usually have four main causes: • Losses of grain over the cutterbar • Losses of grain caused by insufficient threshing • Grain losses over the straw walkers • Grain losses over the cleaning stage • Losses of grain over the cutterbar • Adjust the reel tine position to suit the harvesting conditions.
• Adjust the reel speed to suit the ground speed. • Set the clearance between the reel and the intake auger properly. • Adjust the hydraulic fore and aft reel adjustment to suit the present conditions. • When working in crops with hanging ears, install a crop lifter on every second finger. • Adjust dividers to avoid build-up of material. • Adjust intake auger height to suit crop conditions.
