Give the machine a job description
Before comparing models, describe the result you need. “Maintain the grass around young orchard trees” is more useful than “buy a mower”. It tells a supplier that manoeuvrability and obstacles may matter as much as working width.
A useful brief covers five things: the task, the material or ground involved, how often it happens, the access route and the finish you expect. Add the time you can realistically give to it. Keep separate briefs for distinct jobs rather than forcing one machine to do everything.
Record the holding's limits
Measure the narrowest opening on the complete route to the work, including doors and turns. Record the usable opening, not the nominal gate size. Measure with machinery stopped and safely isolated; do not work around moving equipment.
Describe the ground without guessing a safe operating limit. Note wet patches, ruts, slopes, hidden obstacles and public access. Ask the supplier to explain the manufacturer's limits and the assessment needed for your intended use. A photograph can help explain the setting, but it cannot establish that machinery is safe there.
Record available storage dimensions and servicing access. Include the space needed for the proposed attachments and the route to remove them. If a machine needs site facilities you do not have, include those costs before comparing quotations.
Ask for an answer in writing
Send the same brief to each supplier. Ask which model and attachment combination they propose, which published specifications support it, what limitations apply and what training is available. Ask for the relevant manuals before committing.
Request a quotation that identifies delivery, setup, handover, warranty terms, service arrangements and any additional equipment required. If compatibility depends on an option, the option needs to appear in the quotation.
The lowest price is only useful when the offers cover comparable equipment and support. Keep a separate line for anything still unknown; do not silently treat it as included.
Example: maintaining an orchard
An illustrative brief might say: “I need to manage grass between established orchard rows, leave access for visitors and store the machine in an existing shed. There are low branches and several tight turns. I can provide measurements and want advice on suitable machinery and operator training.”
That brief deliberately leaves the machine choice open. It lets the supplier explain whether the proposed equipment can deliver the job within its limits.
Turn the brief into a shortlist
Use the machinery planner to explore the broad approach. Where a tractor and implement are involved, gather the makers' figures for the implement matcher. Record unresolved questions beside the result.
Can I use the same brief for a contractor?
Yes. Add the required outcome, access arrangements, timing flexibility and what the contractor is expected to provide. Ask them to assess suitability before agreeing the job.
