I'm looking to buy a utility tractor for planting seedlings in a nursery. I need a 3 point and pto operating at 540 rpm. The tractor will need to move very slow while maintaining pto speed and be able to operate at a slow set speed of 1/4-1/2 mph. I'm considering a Kubota L5030 with HST drive. In first gear with infinite speed control, will it maintain these slow speeds? I'll also need good 3-point lifting capacity to lift a heavy planter. Ideas and recommendations welcome. Thanks
