How to Choose a Big John Tree Spade

Two things pick the model: the trunk caliper of the largest trees you plan to move, and the machine that will carry the spade. Start with the carrier you own or plan to buy, then match the caliper.

The model figures below come from each model’s spec sheet. Click a model for its full specifications.

Tree Spades by Carrier

Carrier Caliper, rootball Models
Skid steer 1 to 5 in., 20 to 54 in. Model 20, 28, 36, 40, 44, 48, 54
Trailer 1 to 7 in., 44 to 62 in. 44DTG, 54, 55DTD, 65DTD

  • Skid steer: prepared-ground nursery digging. The spades weigh 1,200 to 3,000 lbs and need a minimum hydraulic drive of 10 to 16 GPM.
  • Trailer: self-contained, tow-along spades for landscapers, municipal crews and occasional use. The 55DTD and 65DTD ride on a 236 in. trailer.
  • Truck: nurseries through professional movers of mature trees, with an on-board water tank for unprepared ground. The 45D runs on a single-axle truck; the 55D through the 90 series need a tandem axle.
  • Loader: tough and sandy soils, with the flexibility to keep using other loader attachments. The 52DL and up need a 20 GPM minimum drive, and most DL models ship with blank attaching plates.
  • Tractor, 3-point hitch: prepared soil and tree nurseries. Mounts on the front or back of most tractors. The DL loader models also list tractors as a host machine.

Tree Spades by Trunk Caliper

Find the trunk caliper you move most, then read across to your carrier. Each cell lists the models rated for that size.

Tractor 3-point hitch spades are made to fit your machine, and the 100DL loader spade digs a 100-inch rootball, so ask the team for a match on either.

New or Used

A new Big John spade lets you choose the optional features you need and skip the ones you don’t. If budget comes first, the used tree spades for sale page lists trade-in and demo units, including models no longer in production. Units sell, so check the current list before you call.

Size Before You Shop

Measure caliper 6 inches above the ground on trunks up to 4 inches, and 12 inches above the ground on larger trunks. Then enter it in the tree caliper to rootball calculator for a recommended rootball width, a weight estimate and a matching model.

Before you commit, the tree spade buying guide walks through blade configuration, carrier compatibility, total cost of ownership and a pre-purchase checklist.

Choosing a Tree Spade: Common Questions

What size tree spade do I need?

Size the spade to the largest trunk caliper you move, not the average. For 6-inch trees, that points to the 55D or 65D truck spade, the 65DTD trailer spade, or the 52DL or 62DL loader spade.

What is the largest tree a skid steer spade can move?

Big John skid steer spades handle trees from 1 to 5 inches in caliper. The Model 48 and Model 54 cover the 5-inch end, with 48 and 54-inch rootballs. Past 5 inches, step up to a trailer, truck or loader spade. The skid steer tree spade guide covers hydraulic flow and mounting.

Do you build tree spades for tractors?

Yes. The 3-point hitch tree spade mounts on the front or back of most tractors and suits prepared soil and nurseries. The DL loader-mounted models also list tractors as a host machine. Contact the team to match a model to your tractor.

What is the largest tree a Big John spade can move?

The 100D truck spade is rated for 12 to 14-inch trees with a 100-inch rootball that runs about 68 inches deep and weighs roughly 15,000 to 18,000 lbs. The 100DL loader spade digs the same 100-inch rootball.
