It depends on the baler. In any case your tractor would not be ideal, but it may do the job if you have flat ground and just a few acres to bale. Balers don't take much power to run. What they do need is a tractor with enough weight to control the weight of the baler and possibly a wagon. A good modern baler should be balanced enough when running to be fairly smooth. Back in the '60s we used a 45hp Ford 850 to pull a New Holland baler with thrower and the wagon behind it to bale about 100 acres a year. The tractor weighed about 5000lbs with loaded tires and wheel weights. The only problem we had was pulling a wagon up some of our hills if it was more than half full of bales. On most of our ground it was not a problem at all to pull a full load of 100+ bales. By 1968 Dad bought a JD3020 and we used that to bale with from then on. It would pull the wagons up the hills without a problem and it was a lot safer going down them. The bigger, heavier tractor was better, but the smaller Ford did the same job for many years before.
To be safe, you want to make sure that the tractor is not pushed around by the baler if you have hills to go up and down. Problems can occur when turning on hills, as well. Bottom line is safety. Good luck.
