Stabilizing Pads
Our stabilizing pads create a wider base during a dig, better distributing the weight than competitors’ spades so you can use more down pressure during a dig.
The BIG JOHN Model 90 sets the standard for large truck mounted tree spades and is the most popular model for large tree movers wanting to move up to a 12” caliper tree.
It is a durable, fully contained, one-operator system built to perform in the most rigorous tree moving conditions. It can handle trees up to 12" in diameter and has a 45 gallon oil reservoir.
Our stabilizing pads create a wider base during a dig, better distributing the weight than competitors’ spades so you can use more down pressure during a dig.
On-board water storage provides lubrication for tough digging conditions needed for unprepared digging conditions. Our standard hose attachment makes cleaning and maintaining your spade a snap as well as providing water during a long-distance move if needed.
Correct for trees that have a natural tilt with internal leveling pads that allow you to adjust the spade’s digging position before relocating the tree to its final destination
Gate hinges designed for stressful conditions, our skid steer spades feature heavy duty gate hinges that beat the competition for longevity.
Our blade edges are the toughest in the business, cutting through not only tough root systems but allowing you to dig in tough soil conditions. Dig in just about any conditions with ease and minimal annual maintenance.
Anyone can learn how to operate a BIG JOHN spade with minimal instruction and successfully dig a tree in a matter of minutes. Maintenance requirements are simple, quick, and affordable with a minimal time commitment to keep your spade at peak performance.
Made with top grade plastics for heavy duty use, our slide blocks dig for thousands of tree moves with ease and simplicity. Fewer moving parts, no bolts to rust, and no small plastic parts to keep track of make the simple design of BIG JOHN spades last decades longer.
Our towers are designed with steps along the inside of the spade to give canopy access during a dig instead of only after the dig when the tree is lowered to the deck.
Made in America of highly durable cold-formed steel, our dual contoured blades stand up to tough, rocky, and sandy soils for on-site moves without prepare ground. Each 90 inch tree spade is mounted to the truck of your choice, with additional specifications below.
