Q&As

Q: Will this fit my 1974 610 bobcat skid steer?

8 months ago
1 Answer
  • A: No, the AgKNX 18-21 HP Hydraulic Digger with Multifunction Skid Steer Mounting Plate will not fit your 1974 Bobcat 610 without a specialized adapter. The modern AgKNX digger uses a universal skid-steer quick-attach plate, which is not compatible with the older, pin-on attachment system of the 1974 Bobcat 610.

Q: This is listed as 2"hex drive, and also I think round 2 9/16"? What earth bits are supposed to be used with this that are available through TSC? I can locate rock auger bits on TSC Online but the only 4'x6"-12"+ earth bits I see are for 2" round.

Q: Do you sell the forks which would match? Do you sell a stump attachment?

2 years ago
1 Answer
  • A: Sorry, we don't sell hay spear tines or fork lift tines with the skid steer mounting plate. We can do a special order and sell them with hay spear tines if you are interested. We also don't have a stump grinder attachment. We do however have a stump planer that works with the powerhead. If you are interested in the stump planer you would need our bigger powerhead / gearbox to operate it. It takes a lot of torque to operate a stump planer. Thanks

Q: What is the torque rating of the motor used in this product?

2 years ago
1 Answer
  • A: We have a few different models and I can provide the torques. HP21 is our standard model. Most customer using it to dig holes are pretty happy with this unit. However, if you are using it for a stump planer or other equipment that might require higher torque you might need one of our other powerheads. Hp21 @ 3000 psi the torque is 1373 ft-lbs. HP27 @ 3000 psi the torque is 1893 ft-lbs HP41 @ 3000 psi the torque is 2987 ft-lbs HP49 @ 3000 psi the torque is 3823 ft-lbs If your machine has a higher pressure rating than 3000 psi the torque values will be higher. Hope this helps, Jon

Q: Would this unit fix on a Vermeer 725 XT mini Skid loader?

3 years ago
1 Answer
  • A: Unfortunately the universal skid steer mounting plate that attaches the hydraulic digger to your mini-skid steer will not fit. It's designed for a full size skid steer. The HP21 gearbox/motor will work with your mini skid steer but the mount will not. Sorry.

Good motor, bad auger quality

a year ago
The quality of the auger bit is poor. The replaceable carbide bits that bolt onto the auger were previously used as they were scratched and the nut and bolts were rusty. On the third hole, it hit a rock and the weld that holds the 2" hex head adapter to the round shaft twisted off. The weld is very poor, a soldering gun could have done a better job. As an improvement, there could be bolts that hold the hex head to the shaft.
