Harvest is completed, and grain is in the bins, but there’s still work to be done. GSI District Manager Dave Ellis says it’s important for farmers to perform postharvest grain system maintenance.
“If they haven’t already done so, now is the time to check their grain bins, dryers, and grain handling equipment,” he says. “Maintenance work following harvest helps prevent preseason replacement, and an ounce of prevention can help save farmers tons of problems next season.”
Ellis’ recommendations include:
- Grain pit: Clean out the grain dump pit to prevent it from filling up with debris or allowing any remaining grain to rot, which could attract rodents or other pests. If the pit has a sump pump, ensure it is working to avoid water buildup.
- Grain conveyors: Inspect the bearings on grain legs and conveyors to make sure they are in good working order. Check that grain elevator belts and buckets are intact and that belts are tight and replace as needed.
- Bins: Clean up around grain bins and check for any damage that could allow water to enter, leading to grain spoilage.
- Aeration: Clean fans, removing debris or any other obstructions that could reduce performance. Inspect the motor and electrical connections to determine if any repairs or replacement parts are required.
Ellis adds that grain dryer maintenance is especially important. “Walk around your grain dryer system with a notepad to make reminders of what needs to be looked at by your grain handling equipment dealer, and make an appointment for needed repairs or replacements,” he advises.
Key dryer checks include:
- Disconnect all power and turn off the gas supply before proceeding with any postseason maintenance.
- Open all accessible doors and completely clean out all remaining material, either with pressurized air or a high-pressure sprayer, to eliminate foreign material from degrading dryer components. After clearing, leave access doors open during the non-drying season.
- Inspect power and control panel boxes for insect infestation. Be aware of any areas that may allow rain, snow, or even birds to get into these boxes, and make any necessary repairs.
- Inspect burner ignition wires, flame detection wires, and control and power panel wiring for deterioration and replace them if necessary. Also, take time to inspect and tighten all wiring connections that might have loosened during the drying season.
- Visually inspect bearings to see if they need replacing or seem suspicious. Do the same with any drive belts and chains, and lubricate those chains for the winter.
