Own a Header or Hire a Contractor? The Real Numbers for Australian Farmers

New headers now routinely top $1 million. A decent used machine starts around $300,000. And a modern header might spend ten months of the year in the shed, doing exactly nothing except depreciating.

So when harvest rolls around on the Darling Downs or across the Liverpool Plains, should you own your gear or ring a contractor?

The honest answer depends on how many hectares you are cutting and how much risk you can stomach. Here is what the numbers actually look like.

What It Actually Costs to Own a Header

The purchase price is just the start. A new Class 7-8 header today runs $800,000 to over $1.2 million before freight and front. Used machines range widely: a solid eight-year-old unit might fetch $250,000 to $400,000 depending on hours, model, and what the market is doing.

Then come the annual costs that most people underestimate.

Research by the Grains Research and Development Corporation (GRDC) modelled the full ownership costs of a $1 million harvester. The annual bill breaks down roughly as follows.

• Depreciation: $90,000 per year. The industry standard rate is 10 percent per annum, and headers are widely regarded as the fastest depreciating machinery on the farm.
• Finance and interest: $54,000 per year.
• Fuel and lubricants: $71,800 per season.
• Labour (hired operator): $25,000 per season.
• Insurance, shedding and registration: $5,500 per year.

That comes to approximately $246,000 per year in identifiable costs, before repairs and maintenance, which can add considerably more, particularly on older machines. GRDC estimates the full operating cost of a harvester and chaser bin combined at $500 to $800 per hour once all costs are included.

The numbers shift for a $300,000 used machine. Depreciation and interest alone run roughly $50,000 to $55,000 per year. Add variable costs and you are still looking at $100,000 to $150,000 per season before the key turns.

Headers are, by most measures, the fastest depreciating machinery on the farm. That is the starting point for every conversation about ownership versus contracting.

What Contracting Costs

Australian Custom Harvesters publishes suggested rates each year. Their current guide, valid from February 2025, puts contract harvest rates at $30 per tonne ex GST for average crops in good conditions, with fuel supplied by the grower. For a chaser bin, tractor and operator, the suggested rate is $300 per engine hour.

In Western Australia, rates typically run $37 to $50 per hectare excluding fuel, depending on crop conditions and region.

These are guides, not fixed prices. Rates vary by machine size, crop type, yield, conditions, and how tight contractor availability is in your region. In a busy season, farmers in the northern grains belt have paid above the suggested rate to secure someone. In a quiet year, negotiation goes the other way.

Where the Economics Cross Over

The break-even point depends on your specific situation, but GRDC analysis gives a useful benchmark. At 1,000 hectares, owning a $1 million machine returns a loss on the machinery investment. At 2,500 hectares, the same operation returns a profit of roughly $44,500 at around 10 percent return on assets.

For a used $300,000 header, the crossover sits in a similar zone. Below roughly 2,000 to 2,500 hectares, contracting tends to be cheaper on a per-hectare basis. Above that, ownership starts to make economic sense, assuming consistent utilisation through the season.

The reason is simple. A header is a fixed-cost asset. The more hectares it cuts, the lower the cost per hectare. A machine working 2,500 hectares costs roughly half as much per hectare as the same machine working 1,200 hectares. This is precisely why a contractor can often undercut the true cost of farm ownership on smaller properties: they spread fixed costs across multiple clients and follow the harvest circuit from Moree south to the Riverina.

The Security Argument That Pure Maths Misses

Here is where the economic case alone falls short.

A farmer near Goondiwindi with 1,800 hectares of wheat and canola might calculate that contracting is marginally cheaper. But what happens if their preferred contractor gets a bigger job, picks up a breakdown, or over-commits for the season?

Timing at harvest is not like timing a trip to the mechanic. Crop condition can deteriorate in days. A week’s delay in a poor finish can cost far more than the difference between owning and contracting. It is not a hypothetical: contractors operating at capacity during a compressed harvest window routinely face impossible scheduling demands.

This is why a large number of medium to large farms retain some owned harvest capacity. Not because the economics are perfect, but because it provides insurance against being caught without a machine when it matters most.

The SA farmer who paid $300,000 for an eight-year-old header to cover 1,000 hectares understood this calculation. The pure maths probably did not stack up. But at $45 per hectare contracted across 1,000 hectares, one botched season costs $45,000 before you count grain quality losses or downgrading.

The Overcapitalisation Trap

Owning a header for harvest security is sensible. Owning enough gear for your best-ever season is not.

This is where many farming operations quietly get into trouble. A run of good years leads to incremental machinery purchases sized for bumper conditions, not average ones. The result is a substantial fixed-cost base eating into margins every year, with gear sitting idle because there is not enough area farmed consistently to justify the fleet.

The test is straightforward. Size your owned capacity for your base year, not your best year. If you consistently run 2,000 hectares of winter crop, own gear that handles 2,000 hectares comfortably. In a bumper year where conditions allow expansion or you take on additional area, bring in a contractor for the overflow.

The exception is if you actively do contract harvest work for neighbours. If your machine is cutting 3,500 hectares per season including 1,500 hectares for other properties, you are spreading fixed costs and the economics look completely different. Some of the best-capitalised machinery operations in the northern grains belt run exactly this model: own the gear, use it hard across a mix of home paddocks and neighbouring farms, keep it profitable.

The Three Models Most Farms End Up In

Pure Contracting

Works well for cropping operations under roughly 1,500 hectares, or in areas with reliable, consistent contractor access. No capital tied up, no depreciation, no machinery headaches. The main risk is availability, especially in a compressed harvest window when every contractor in the district is fully committed.

Full Ownership

Makes economic sense at scale, typically above 2,500 to 3,000 hectares, where fixed costs are diluted enough to compete with contracting rates on a per-hectare basis. Particularly strong when the farm also does contract work for neighbours to offset fixed costs and improve asset utilisation.

The Hybrid Approach

Suits most mid-sized farms in the 1,000 to 3,000 hectare range. Own machinery sized for base or average operations. Use contractors in overflow years or for additional paddocks taken on at short notice. This provides harvest security without the full fixed-cost exposure of owning a fleet sized for peak conditions.

Getting the sizing right is what separates a well-capitalised operation from an overcapitalised one. Own too little and you are exposed at peak season. Own too much and you are paying for depreciation on capacity you rarely use.

Running Your Own Numbers

Australian Custom Harvesters has a cost calculator at customharvesters.org.au/cost-calculator that lets you plug in your purchase price, expected hectares, fuel price, repair budget, and finance rate. It is worth running before any machinery purchase decision.

For the contractor side of the economics, the contractor revenue guide on AgPages covers how contractors price their work and what drives rates up or down in any given season.

Finding a Contractor You Can Trust

If you are contracting some or all of your harvest, the contractor relationship matters as much as the rate. Locking in early, being upfront about crop conditions and timing expectations, and using a platform where contractors see your job and can respond directly removes most of the late-season scrambling.
