I ran a Vermeer Rebel 5400 4X5 baler with a John Deere 1070 for years. It struggled a little on steep slopes with a full bale but we were baling around 160 acres twice per year. Same tractor ran a New Holland 9 ft haybine just fine if you took your time. That tractor was rated for 39 engine/35 pto HP. You may have better luck finding a 4X5 baler if you are looking used
