3-Point Backhoe Buying Guide: How to Choose a Tractor Backhoe

A three-point backhoe turns a tractor you already own into a compact excavator — for a fraction of the cost of a dedicated machine. But not every backhoe fits every tractor, and dig depth, hitch type, and hydraulic source all matter. This guide covers how to choose a 3-point backhoe attachment for your tractor, and where each WoodMaxx model fits.

3-Point Backhoe vs Subframe Backhoe

There are two ways to mount a backhoe to a tractor. A subframe backhoe bolts to the tractor's frame — rock-solid, but semi-permanent and expensive. A 3-point backhoe mounts to the standard three-point hitch and runs off the tractor's hydraulics or its own self-contained pump, so it goes on and comes off in minutes and moves between tractors. For most landowners digging footings, trenches, stumps, and drainage, a 3-point backhoe delivers the capability without the commitment.

The Numbers That Matter

1. Dig depth. This is the headline spec — how deep the bucket reaches on a single setup. WoodMaxx names its backhoes by class: the WM-6600 digs to roughly 7 feet, the WM-7600 to about 8 feet, and the WM-8600 to about 9 feet. Match depth to your real jobs (footings and water lines usually need 4–8 feet).

2. Tractor weight and horsepower. A backhoe puts serious leverage on the back of your tractor. Bigger backhoes need a heavier, higher-HP tractor to stay planted and safe — undersizing the tractor is the most common mistake. Confirm your tractor's weight class suits the model before you buy.

3. Hitch category and hydraulics. Confirm your three-point hitch category matches, and decide whether you'll run the backhoe off the tractor's hydraulics or a self-contained PTO pump (WoodMaxx offers PTO pump options for tractors that can't supply the flow).

Add a Thumb for Real Versatility

A backhoe digs; a backhoe with a hydraulic thumb also grabs. Rocks, brush, logs, and debris become movable instead of just diggable. If you're clearing land as much as trenching, a thumb is the single best add-on — WoodMaxx backhoes are thumb-compatible.

Match the Bucket to the Job

Bucket width changes what a backhoe is good at. A narrow bucket (like a 15") is ideal for utility trenches and tight footings; a wider bucket (24") moves more material per pass for drainage and general digging. Urban Supply stocks both WoodMaxx backhoe buckets and ripper attachments so you can tool the machine to the task.

Our Recommendation

For compact-tractor owners: the WM-6600 handles the footings, water lines, and stump work most properties need. For deeper trenching on a mid-size tractor: the WM-7600 adds reach without a huge jump in price. For utility tractors and serious depth: the WM-8600 is the digger. Add a thumb to any of them if you're clearing as well as digging.
