Machinery Cost per Unit of Output

Machinery cost per hectare is a statement about the machinery. Machinery cost per tonne is a statement about the farm, and the difference is entirely the yield sitting in the denominator. The same combine, the same tractor and the same drill cost twice as much per tonne on land yielding three tonnes per hectare as on land yielding six, and no amount of careful buying changes that. It is why identical equipment lines are comfortable in one district and ruinous in another.

This is the benchmark that separates farms with similar gross revenue and very different bank balances. Machinery is typically the largest single component of the fixed cost, and unlike fertiliser or chemical it cannot be adjusted once the decision is made — depreciation and interest arrive on schedule whether or not the season cooperates. Expressed per tonne of output it can be compared directly against the crop's price, and the question becomes concrete: how many dollars of every hundred the grain earns are going to iron?

There are only three levers, and it is worth being clear that they are the only three. Spread the same machinery over more hectares, which is the argument for custom work, machinery sharing, or simply farming more land. Raise the yield, which lowers the cost per tonne without touching the machinery at all. Or reduce the machinery itself — a smaller line, older equipment, longer replacement intervals, or hiring the operation out instead of owning the machine that performs it. Everything else is a variation on one of those.

The number has to be built on total machinery cost, ownership and operating together. Depreciation, interest on the capital tied up, insurance and housing are the ownership half, and they are invisible in a chequebook, which is why they are the half that gets omitted. Fuel, repairs, lubricants and labour are the operating half and they show up as invoices. A machinery cost per tonne built from invoices alone is the familiar mistake in its most expensive form: the variable half counted, the fixed half missing, and a farm quietly convinced its iron is cheap right up to the moment the line needs replacing.
