We pull a 1290 with a Puma 160. Plenty of horsepower for the baler.  The big flywheel makes it work.  I’m not familiar with the cutter balers, they might take enough power that you are right on the edge.  Our ground is all flat but we can bale heavy hay slow or light hay fast no problem.  The baler pushes the tractor a bit compared to the other one on the Magnum 225.  Still smoother and gets way more done than the Hesston 4790 and Magnum 190.

If shopping, look at the 2008-10 Magnum CVT tractors.  No DEF and CVT is perfect for baling.   Magnum frame has a lot more weight to it than the Pumas
