This is the full set of facts a commercial forestry machine purchase rests on. It exists because the most expensive mistakes in this market are not made at the negotiation — they are made earlier, when a buyer commits without establishing what the machine actually has to do.
Work through it before requesting quotes, and again before signing. Any line you cannot answer is not a gap in the paperwork; it is where your commercial risk sits, and it will surface later as a machine that does not suit the work, a rate that does not cover costs, or a residual value that does not materialise.
The Work section comes first deliberately. Available work, contract duration and required output determine the production system, which determines the carrier, which determines the attachment. Reversing that order — choosing a machine and then looking for work — is the single most reliable way to end up with expensive idle capital.
