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 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.
