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 blades are cold-formed from AR400 steel, making them durable and strong for all kinds of digging conditions and maintaining their integrity for decades. The blades are also fluted to distribute the stress of digging better in tough conditions.
