Frequently Asked Questions
What's the advantage of vertical vs. horizontal stump grinders?+
Vertical grinders offer better visibility and access in tight spaces, while typically requiring less machine weight for equivalent cutting power. Their compact design makes them ideal for small excavators and tractors.
Can I operate this attachment on a tractor without rear hydraulics?+
For tractors without rear hydraulics, we offer PTO-powered hydraulic power pack options that provide the necessary flow and pressure for optimal grinder performance.
What maintenance does the vertical stump grinder require?+
Daily greasing of bearings, periodic inspection of teeth and cutting wheel, and regular hydraulic filter changes (per machine manufacturer recommendations) will ensure long service life.
How does the vertical design handle large diameter stumps?+
Our vertical grinders use a progressive cutting technique - operators make multiple passes around the stump perimeter, with 360° rotation allowing complete access without repositioning the machine.
What safety features are included?+
All models include: mechanical rotation lock, protective shrouding, emergency stop capability, and reinforced steel safety chains to contain debris.
