One gate measurement is not an access plan
A machine may fit through a straight opening and still be unable to reach the field. Turns, doorways, narrow tracks and the space needed to manoeuvre all matter. Survey the whole route before deciding on equipment or accepting a delivery.
This guide helps you collect information for a supplier. It does not establish safe clearances, ground-bearing capacity, slope limits or a lifting and unloading plan.
Walk the route first
Start where the vehicle or delivery is expected to arrive. Follow the intended route to the work area and storage location. Record each restriction in order and mark it on a simple sketch. Include gates that open into the route and places where a turn must begin before the machine reaches an opening.
Measure usable openings, including protruding hinges, latches and posts. Record height restrictions and uneven surfaces. Do the survey away from moving machinery and keep clear of traffic or other hazards. Arrange competent help where measurements cannot be taken safely.
Ask for the right machine dimensions
Request overall dimensions in the exact configuration you plan to use. Distinguish working width from transport width and include attachments. Ask about the space needed to turn and access the machine for maintenance.
Some dimensions vary with tyres, options or attachment position. Ask which measurements apply to the quoted machine. Do not rely on a brochure image or an unrelated model in the same range.
Make a restriction register
Give every restriction a short name, such as “orchard gate” or “shed doorway”. Record width, height where relevant, approach direction, surface concerns and a photograph reference. Leave unknown dimensions blank and mark them for checking.
Share the register with the dealer or contractor. Ask them to assess the proposed route and explain any required changes before equipment is ordered. A calculated width comparison is only one part of this assessment.
Check storage and delivery separately
A shed needs room for access, attachments and the activities the manuals require, not just the parked outline of a tractor. Delivery also introduces a different vehicle and an unloading operation. Ask the supplier to confirm the delivery requirements rather than assuming the working route is suitable for a transporter.
If access changes are proposed, assess them as a separate job. Do not remove a boundary, alter a structure or use an improvised unloading arrangement simply to make an arriving machine fit.
Use the findings in your shortlist
Put the restriction register beside the implement matcher results and the supplier's specifications. A width check can reject an obvious mismatch; passing it does not prove that the route is usable.
What margin should I allow?
There is no universal margin in this guide. Ask the manufacturer or competent supplier to assess the actual machine, route and conditions. Record their advice with your measurements.
