34″ PTO Stump Grinder | 45-80 HP | CAT II | 540 RPM
3 Point Hitch Stump Grinder – 3P34
The 3P34 PTO stump grinder is designed for tractors equipped with a 50–80 horse power motor allowing you to grind into stumps with a 34″ Rotor carrying 54 replaceable carbide teeth. The rugged gear box takes up to 80 HP and develops 803 ft/lbs of stump destroying torque. Designed for Cat 2 3PH and 540 PTO this versatile stump grinder has 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.

Stump Cutting Time Chart
Fine tune the performance of your Stump Blaster easily with the Flow Control knob. The Flow Control allows you to adjust the cutting pass speed, to match the size and performance of your tractor. This gives you the smoothest cut possible and with the full return back to the start position, the quickest overall stump grinding time possible.
Like the finest saw blades, the cutting teeth on Stump Blasters are carbide tipped. This incredibly hard material ensures reliable cutting performance. When grinding stumps, buried hazards are inevitable; gravel, stones even metal posts are not uncommon to “find”. Our carbide teeth are designed to stand up to this abuse and keep on blasting stumps to dust.
The high number of teeth means that each tooth needs to do less work. Each of the Stump Blasters teeth only need to make a small cut, because the work is shared by more of our rugged teeth they last longer and usually only require 2 or 3 replacements at a time. The bolt-on designed teeth allow for straightforward replacement.
The rugged gear box transfers power from the tractor’s PTO to the rotor creating 803 Ft.-Lbs of torque and turning the rotor and hungry teeth at 810 RPM.
The massive ¾” thick steel rotor provides the back bone for the Stump Blaster cutting system. It’s the anchor for the carbide tipped teeth. For smooth operation it’s important that the rotor remains solid, with no flexing. The rugged rotor also provides the Stump Blaster with the extra momentum needed when the grinding is tough, making sure the Stump Blaster can power through the hardest stumps.
The Stump Blaster’s carbide teeth extend a full 1-¼ inches from the rotor. This prevents chips and mulch from getting plugged. More chip clearing produces smoother operation and reduces heat build-up that can damage the rotor and cause premature tooth failure.
The heavy duty base provides a solid base for grinding. This allows for more consistent grinding performance and reduces the stress on your tractor.
The deflector floats as you grind providing chip and debris control from first cut to maximum depth without getting in the way. In tight grinding situations the deflector can be flipped up out of the way.
EXTERNAL CONTROL (OPTIONAL)
This optional control is mounted on an adjustable arm. The control is great for smaller tractors with limited HP for better cutting control and for tractors with only one remote.
HARDENED STEEL BUSHING
Spring Bushings made from high grade chrome-vanadium AISI 6150 spring steel on all main pivot points.
Our grease pins are zinc plated to prevent corrosion which will allow for smoother operation of the units joints over their lifetime.
SWING & LIFT CYLINDERS
Get right to grinding with less maneuvering of your tractor and less damage to the grass. The swing cylinder gives the operator a 65 degree grinding range without moving the tractor. The lift cylinder allows you to raise and lower the grinding head to get in start position as well as lowering the head after a pass so you’re ready for the next bite
