The AgKNX Model 400 Post Hole Digger is for most sub-compact, compact and Category 0 tractors with CAT 1 pins, allowing for fast post hole digging with convenient, safe operation from the tractor seat. The Model 400 can also be used on smaller CAT 1 tractors. The post hole digger features a heavy-duty gear box, durable driveline, and rust-resistant powder coat finish. Quick connect to 6 spline PTO to quickly change out implements. Rated for tractors up to 45 HP, this post hole digger can make quick work of your next job. CAT 0, Compact and Sub-Compact tractors typically come in 2 different configurations concerning the 3-pt. Some come with CAT 1 pins and other with CAT 0 pins. A CAT 0 3-pt includes 5/8" top link pin and 5/8" lift arm pin. A CAT 1 3-pt includes a 3/4" top link pin and 7/8" lift arm pin. Our Model 400 Post Hole Digger works with tractors that have the CAT 1 pins. CAT 0 lift arm pin is sold separately.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

Q: Will this work with a kubota B7500?

1 Answer
  • A: Thank you for your question. It is designed for tractors with a Category 1 three-point hitch and up to 45 PTO HP, which aligns with the general specifications of a Kubota B7500. However, we are unable to confirm compatibility with the B7500 specifically. We recommend verifying with AgKNX customer support.

Q: Is this able to be used with the John Deere 1025R with a 12" x 48" auger?

a month ago
2 Answers
  • A: It will fit the tractor but longer augers are difficult to use with these sub-compact tractors. It just won't have the clearance in most cases. Plus 48" diameter is way too big for this digger. It won't handle properly

Digger and auger seem to be of good quality; overall service of Tractor Supply and Manufacturer has been great through the process. Looking forward to installing my fence using these items.
