Keep it Clean


Paying attention to combine hygiene will help prevent the spread of arable weed seeds and reduce the fire risk from clogged machinery in the hot working days we have been experiencing lately.
In this blog Mike Wareing, John Deere Territory customer support manager shares his top tips on combine hygiene.

Top Tips to Keep it Clean

Clean the machine down regularly, certainly daily and maybe for certain areas of the machine, more than once a day. How much debris accumulates will depend on the crop you are harvesting, the weather conditions and the wind direction.

Use the machine’s in-cab automatic cleanout mode.

This turns your rotor speed and fan speed to maximum and opens sieves and concaves wide. Running the machine at high RPM, when the separator and header are engaged will process any residues. The high velocities and air flows will help clean the machine out, blowing everything out the back. When the dust has disappeared you know the machine has blown out as much as it can.
Once you have done that, and this is again in the operator’s manual, if you decrease the engine RPM, leaving everything engaged and then rev the machine up and down a few times this can help dislodge any material inside rotors or concaves.

Now shut the machine off and take the key out.

Clean the combine from top to bottom using compressed air or high velocity air. If you haven’t got a high volume compressor then leaf blowers are great and battery powered ones are available.

Start at the top of the machine and work your way down. Be aware that you have just run the engine so it will be hot. Blow the material off the machine, down towards the ground.

Work your way methodically down and around the machine. The guides will tell you which areas to pay particular attention to, once you get to ground level you’ll be pretty much done, in terms of a field to field clean.

It is of course up to the operator to evaluate how thorough a clean out the situation demands but I will say the more the operators clean out the machine the more familiar they become with the bits where debris and weed seeds are likely to become lodged.
