I have powered a 7' haybine and a IH 37 sq baler easily with both our L2550 and L3450 tractors. -- We have gone to a drum mower now because of slow cut speeds or clogs with the haybine. -- I think a 9' would be ok if the haybine cutter is in good shape and you dont have hills.I am wondering if a L3540 is too small to pull a 540 pro rated 9ft haybine and a square baler around? Wife needs bales for her horses, hope tractor will be big enough.
If used lightly its ok. But in heavy rows the plunger motion and compression forces for firm bales can react enuf against travel speed to throw the HST trans into pressure relief with every stroke. If that happens it will eventually fail the trans.I think you will be fine. My dad cut, raked, and baled hay for about 12 years with a B8200 hst and still hadn't had any issues with it. It was not ideal and you had to be careful since the baler was heavier than the tractor but it was what he had and it worked.
I wondered the same question myself as I have the L3430HST. While I have not gotten into hay yet, I came across this thread where member rankrank1 offered some good advice about smaller balers that may work for you.

I am eager to follow this discussion as it seems from my reading that tractors of this size could bale a few acres of flat land going slow and not also towing a wagon behind the baler.
I've seen a BX run a small square baler although I had to laugh at what the plunger was doing to the tractor!!!
We do fine with either of our 25-30HP Kub L gear tractors. Direct gearing handles the plunger surge fine. Never much of an issue unless youre packing real hard bales ... or really honkin on a big row and turning out a bale every 40'.if your going to keep baling hay you need to get a 50hp tractor.your tractor will pull a rake.
I too wouldnt worry about a big hydro like you have. The concern was for the ~30HP downward if used with total abandon, vs some care to ease the cases of high oscillating ground drive load.Did run a 9' Haybine behind my L3710 hydro a little bit before trading for my cab equipped L5740. The sickle doesn't take that much power but the rolls can suck it up. My New Holland baler spec sheet says 35 HP for their small square balers. I hear people say a small square baler will rip a hydro transmission out but that baffles me. Our L5740 will handle a small square baler quite well. The flywheel is there to even out the driveline load. I would, however, try to borrow somebody's equipment first to try it lout before jumping in and buying. By the way back when the dinosaurs were roaming we used our Farmall H on the baler with a wagon behind but that was underpowered. I think a H is about 26 HP. It could handle the baler okay but pulling the load was tough, especially since it didn't have live PTO. Dad even took an Allis-Chalmers B in on trade that had been used got baling. I think that is about 18 HP, maybe less. Once again no live PTO, fairly fast low gear like the H. Would have loved to have a hydro in those days to control speed in varying windrows.
