Demonstrating a Grain Combine on Your Own Grain
A buyer's guide to requiring a combine demonstration on the buyer's actual grain, with practical checks for throughput, weight, clearance and fuel capacity drawn from catalog reference values.
Make the demonstration run on your grain, from your fields, not on the seller's sample crop. Before the trial, agree which grain lot and moisture condition will be used, how the sample will be taken, and who records losses behind the machine.
Ask the supplier to state how the catalog throughput capacity of 18 kg/s was measured and whether it applies to your crop and settings. Treat that figure as a reference value, not a promise for the supplied model. Confirm the header fitted for the trial, since the operating weight without header is listed as 18,950 kg, unloaded, and the header changes the load on your soil and transport.
Check whether the 466 mm minimum ground clearance suits your tramlines and field access, and whether the 1,000 L fuel tank covers a full working day on your farm. During the demonstration, record grain loss, sample cleanliness and unloading time at your normal forward speed.
Before requesting a quote, confirm with the supplier which grain and moisture the demonstration will use, the exact machine and header configuration offered, how the throughput figure was derived, and what acceptance test and measured loss limits will be written into the contract.
