If it is designed for a skid steer & "adapted" to a compact tractor, you're best bet is one of the larger compacts such as the New Holland "class III" - TC35, 40, 45 or Deere, Kubota, etc. equivalents.
Skid steers have in excess of 2,000# lift capacities. the larger compacts have about 1,500# +/-. The 30 HP generally have a 1,000# +/-.
I know my little TC18 is best used for moving loose material, not "Digging" anything up.
