True, Dan, but you seem to running a pretty old and rather small baler. What model is it?
So many of the "small" square balers available today are a little beafier and heavier than that. Most all of the current makers in the small square biz suggest no less than 35 PTO, which means around 45 engine HP, to operate their rigs.
A baler, round or square, is not an implement I want to put too little tractor in front of since operating them is not necessarily about HP or speed.......but the ability to sustain the forces of the baler back toward the tractor.
