A walk-behind trencher (Barreto 24 in class) cuts a neat, consistent slot at a fixed width. A mini excavator digs whatever shape you steer, around utilities, and through dirt the chain does not like. Long, straight irrigation in good soil is a trencher job. Footings, bell holes, and rock are excavator jobs.

Figures below are typical ranges for this equipment class — not a spec sheet for one serial-numbered unit. Used rental inventory rotates; we confirm height, capacity, width, and weight on your quote.
Where the Barreto wins
Hundreds of feet of irrigation or power in sandy or loamy soil, one width, one depth. The chain is faster than an operator feathering a bucket. Spoil comes out in a windrow that is easy to backfill. You still need a plan for driveways, roots, and unmarked lines.
Where the excavator wins
Turns, tee fittings, existing utilities, cobble, and any trench that has to get wider than the chain. A thumb on an E35 class machine also lets you place pipe and pull roots. If the job is 40 feet of sewer with a tap, do not rent a trencher because it sounded cheaper.
Utah soils and chains
Cemented gravel and cobble eat teeth and stall walk-behinds. We would rather send a mini excavator (or tell you the trencher is a bad idea) than burn a chain for a half-day of progress. Tell us what a shovel already hit.
Who should rent which
Trencher for long, straight, consistent utilities in friendly soil. Mini excavator for everything else. Call (801) 880-8800 with length, depth, and soil.
