he 3P40 HPR PTO stump grinder is designed with high performance in mind, for tractors equipped with a 60–120 HP and 1,000 RPM PTO. This stump grinder will devour large tree stumps with its 54 replaceable carbide teeth and a 34" rotor. Massive rotor and more teeth with a heavy duty HPR gear box make this Baumalight’s most powerful PTO model. This Stump Blaster has the ability to grind a 24" stump in a few minutes with a cutting depth of 25" above ground and 14" below ground. With direct drive from the engine, all the way through the heavy duty gear box to the teeth, a stump grinder on the PTO of a tractor is the most efficient way to use a stump grinder for lawn care or fence row clearing. | Model No. | 1P24 | 3P24 | 3P34 | 3P40 |
