Try using the "Search Website" function available on the first page of

DeWalt DW960 18V right-angle drills produce 310 in.lbf torque at
500 rpm.  I will use 1:1 drive ratio at 24V which should give about
400 in.lbf torque at 650 rpm.  Mounting may not be easy.

In several earlier postings, I recommended the Rule of Fours.
4 inch DIA drive sprockets
400 rpm at each drive sprocket
400 in.lbf torque at each sprocket
4.7 mph with sufficient torque for skid steer
