1
Survey the ground before quoting, not before mobilising
Rock content and stump density are the two variables that most often destroy a quoted cost per hectare. Test-pitting or at least walking representative ground before pricing is cheap relative to discovering the problem with a tiller on site. Where a survey is not possible, price with a stated assumption and a variation mechanism.
2
Size the fleet against the window, not the year
Calculate the hectares required divided by the working days available in the window, then add an allowance for weather days and breakdown days. That number — not annual capacity — determines how many machines the contract needs. Contractors routinely under-resource because they size against a twelve-month average.
3
Choose the ground-preparation method from the soil and the silviculture
Mounding, ripping, scarifying, spot cultivation and full tillage solve different problems: drainage, compaction, competition, residue. The client's silvicultural prescription should determine the method, and the method determines the machine. Buying a tiller and then looking for tilling work inverts the sequence.
4
Plan consumables as a campaign cost
Tiller teeth and tool holders on rocky ground are consumed at rates that can rival fuel. Stock the campaign's expected wear parts before it starts, because a two-day wait for teeth in week three of a six-week window is unrecoverable.
5
Decide own versus hire against the seasonality
Machines used in a single annual campaign carry twelve months of fixed cost against a few weeks of revenue. Where the campaign is short and the work is contestable, hire or subcontract may produce a better return than ownership, even at a visibly higher day rate.
