What Equipment Do I Need to Build a Deck?

Most ground-level decks in Utah are an auger (or a mini), a plate for any gravel landing, and a trailer for lumber and spoils. Elevated decks add frost-depth holes and maybe a compact telehandler for beams. A 44 ft 8k in the backyard is how you explain a new sod bill to the owner.

Equipment for building a deck

Primary machines

Mini excavator or skid-steer auger

Primary

Auger on T550/S550 class; E35 mini when the bit starts bouncing.

Frost-depth piers. The auger wins in clean soil; the mini wins in cobble and for spoils.

Skip it when you are using deck blocks on a tiny ground-level platform and the city said that is fine.

Dump or utility trailer

Primary

Airtow 12 ft for materials; 6×12 dump if you have real dirt to haul.

Lumber in, spoils and offcuts out, without walking it through the kitchen.

Skip it when the supplier is carrying to the backyard and you have two wheelbarrows of spoils.

Optional / nice to have

Plate compactor

Optional

WP1550 class plate. A rammer is the wrong tool on gravel.

Landing pads, gravel under stairs, and the patio the deck will meet.

Skip it when you are building over existing concrete.

Compact 19 ft telehandler

Optional

5,500 lb / 19 ft. The 44 ft 8k is almost always too much machine.

Beam and joist packs for an elevated or second-story deck with side-yard access.

Skip it when everything is ground-level and two people can carry it.

Typical pairing

Typical 12×16 elevated deck: skid-steer auger (or E35 if you already know it is rocky) + dump trailer. Add a plate if you are building a gravel landing. Add the 19 ft telehandler only if beams cannot walk in.

Holes before lumber

Frost-depth piers (often ~30 inches, check the print) in this soil are not a weekend clamshell job once you hit cobble. A skid-steer auger on a T550 is fast in friendly dirt. A mini excavator is faster once the auger starts polishing rock. Do not guess — 811 first.

Material

A 6×12 dump or an Airtow utility trailer beats five truckloads of PT through the house. Composite packs are palletized; forks on a compact telehandler help if you cannot get a truck behind the house.

When height appears

Second-story decks and covered porches sometimes want a 19 ft scissor on a patio slab, or a compact telehandler for beams. They do not want a construction boom because the railing “felt high.”
