The GravelMiser works with most standard tractors equipped with a bucket with cutting edge. The cutting edge blade is necessary to interlock with the drag bar. The bucket and tractor require a lift capacity high enough to lift the GravelMiser’s respective weight:

The 8’ GravelMiser (approx 900 lbs) works 5’ buckets.*
The 6’ GravelMiser (approx 732 lbs) works with 5’ & 4’ buckets.
The 5’ Gravel Miser (approx 566 lbs) works with 4’ & 3’ buckets.

*6’ & 7’ buckets may work with the 8’ model to load and drag, but will likely have a blind spot when aligning with the pick-up bar.
