  • Page 115: Tractor Horsepower

    The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the 260 mower requires a tractor with at least 35 HP, the 272 mower requires a tractor with at least 45 HP and the 284 mower requires a tractor with at least 65 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
