Product & applications
About the stump grinder
A compact hydraulic attachment with a vertical cutting disc for grinding tree stumps below the surface. The narrow disc arrangement suits confined access and smaller excavators.
Features & benefits
Compact vertical disc
The narrow working profile provides access around fences and restricted planting areas.
Chip-deflecting housing
The shroud directs chips downward; it does not replace operating clearance or guarding.
Typical applications
- Residential stump removalGrind accessible stumps in yards and landscape areas with a compact excavator.
- Fence lines and foundation perimetersUse the narrow vertical disc where working access is restricted.
- Below-grade restorationReduce stumps to the selected disc model’s cutting depth before appropriate backfilling. Grinding leaves wood chips; it does not extract the complete root ball.

Machine and attachment mass
Check the selected machine class and 180 or 192 kg operating weight against the lifting chart.
Mounting dimensions
Confirm pin diameters, centres and bracket width or the exact quick-coupler interface.
Hydraulic circuit
Match the selected 30–50 or 45–70 L/min flow; confirm operating pressure and motor drain separately.
Disc and site clearance
Check rotation direction, hoses and guarding. Identify buried services, stones and restricted access.
Product questions
Stump grinder questions
Is this a drum grinder or stump planer?
This page covers a vertical disc grinder. Drum grinders and auger-driven stump planers have different mechanisms.
Is cutting wheel diameter the maximum stump size?
No. It is the wheel dimension, not a guaranteed stump diameter.
Can it work on a small excavator?
The reference configurations cover 1.5–5 t and 3–7 t, subject to interface, hydraulics and lift checks.
What pressure should be used?
The specification table does not state pressure. Confirm the motor and relief settings before installation.

Forestry & Site Maintenance
Forestry mulcher
A hydraulic drum attachment for reducing brush, woody debris and fallen vegetation into smaller material. Fixed cutters work around a horizontal rotor; model selection depends on the excavator and its continuous hydraulic supply.
Forestry & Site Maintenance
Excavator rake
An open-tine excavator attachment for gathering roots, brush, rocks and site debris. Soil and smaller loose material can pass between the tines while larger material is gathered.
