Measure the complete route
Measure the narrowest gate, the approach to it and the space beyond it. Photograph corners, slopes, steps and overhead obstructions from both directions. A machine that fits through an opening may not be able to turn into it. Ask for the proposed unit's travel width and height, including its actual canopy or cab. Where retractable tracks are proposed, have the supplier explain the configuration required for travel and for work.
Describe the excavation and spoil movement
Give the supplier trench length, target depth, material and the intended finished result. Include where spoil will sit and whether it must be loaded into a truck, moved through a narrow passage or taken away. Bucket size is only one part of production: repeated repositioning or waiting for spoil removal can dominate a small job. Ask whether a dumper or another support machine belongs in the same quote.
Compare the complete machine package
Request the exact machine class, suitable buckets, any auger or breaker, and the transport method. A compact unit with the wrong attachment can be less useful than another configuration at a different base rate. Keep ground protection and reinstatement separate in the scope so neither party assumes they are included. Underground and overhead services need a competent assessment before excavation; machine size does not remove that requirement.
A useful enquiry example
Instead of asking for the cheapest mini digger, send the supplier an access sketch, photographs, excavation dimensions, spoil destination and dates. Ask them to nominate a suitable configuration and identify assumptions that require a site visit. Keep that response with the quote so any substitution can be checked against the same constraints. Confirm operator arrangements and how attachments will be delivered, changed and collected.
Put it into a practical brief
For a backyard drainage enquiry, attach an access sketch and label the trench route, existing surfaces and spoil collection point. Ask the supplier to identify whether the proposed excavator can work from the available positions and what information still needs a site visit. If the supplier suggests a smaller unit, ask how that changes the expected sequence and spoil handling. Keep the answer as an assumption to verify, not a promised production rate. The cheapest transport option is only useful if the machine and attachments can complete the agreed scope.
