Mechanisation is about control
Arboriculture equipment should be judged by which exposure and handling step it removes. A grapple saw secures a section, cuts it and retains it. A pruning head reaches repetitive vegetation without a person at height. A forestry grapple takes irregular timber from the drop zone to the chipper or truck. A stump grinder completes the site without another dedicated carrier.
The machine does not remove the need for planning. It changes the plan from climber position and rigging into carrier stability, piece mass, working radius, visibility, placement and exclusion zones.
Grapple saw or mechanical pruner
A grapple saw suits individual limbs and stems that must remain controlled because of houses, roads, conductors or people. A mechanical pruner suits repeatable hedge, verge, orchard and corridor vegetation where cut material may fall into a managed zone. The direct comparison begins with debris control rather than maximum diameter.
Carrier selection for urban work
Compact carriers reduce access and transport problems, but attachment mass consumes a larger share of their lift capacity. A head may sit inside the manufacturer’s carrier band and still leave too little margin for a useful severed section at reach. Check the complete head, mount, coupler and piece against the exact lift chart.
For road and park work, also account for tail swing, track width, ground pressure, overhead services and the space needed to rotate a retained piece. A larger carrier can reduce risk by improving lift margin, yet increase traffic-control and access cost. There is no single best tonne class.
Build the processing chain
The grapple saw puts a piece on the ground. The production result depends on what receives it. If the same head repeatedly places material and then regrips it for chipper feeding, a separate forestry grapple may increase utilisation of the saw carrier and the chipper. If the site generates large timber, plan cross-cutting, loader and truck capacity before the first cut.
Stump work as a second service
A compact excavator with a vertical stump grinder can extend a tree-removal crew into a stump service without a separate self-propelled grinder. The business case is strongest where the carrier already travels with the crew and accesses constrained sites. Measure complete time per stump, including setup, repositioning and reinstatement.
Demonstration and training brief
- use representative species and green piece sizes;
- measure the full grip-cut-place cycle;
- test visibility at the real working height and radius;
- document saw, chain, bar and grapple maintenance;
- practise a trapped-saw and partly severed-piece response;
- confirm controls, cameras and communication for each operator;
- price the wear kit carried on the truck.
The dangerous-tree application guide places those decisions inside the wider site method, and the lift-chart guide handles the mass calculation.
Current models to investigate
Compare models side by side with specification graphs →
Dipperfox SC400 stump grinder
The compact Dipperfox for mini excavators: 190 kg, a 400 mm stump capacity and 590 mm drilling depth, built to put stump removal on a carrier that already fits through the gate.
OMEF TG hydraulic hedge trimmers
The light end of the OMEF range for fine vegetation rather than timber: the 800 mm six-knife TG2 for 1.8 to 2.5 tonne carriers and the 1,200 mm nine-knife TG1 for 2 to 5 tonne machines.
Powerhand EX25 forestry grapple
The lightest EX grapple: 400 kg with rotator and 0.25 m² of capacity, preserving carrier lift on 8 to 12 tonne excavators feeding compact chippers.
Powerhand EX25 grapple saw
The compact rigid grapple saw: 651 kg on an 8 to 12 tonne excavator with a 600 mm saw capacity, preserving more boom capacity for the piece being cut.
Dipperfox SC600 stump grinder
The mid-range and arguably most versatile Dipperfox: a 600 mm stump capacity on the 6 to 12 tonne excavators that civil, utility and landscaping contractors mobilise most often.
OMEF BF cutter bars
Extremely light reciprocating cutter bars (40 to 46 kg) in 1.2, 1.5 and 1.7 m widths for 30 mm class vegetation on 1 to 5 tonne carriers, built for linear metres rather than branch diameter.
Powerhand EX28 forestry grapple
The crossover grapple: 0.28 m² of capacity across a broad 12 to 25 tonne carrier band, for civil clearing, biomass and chipper feeding.
Powerhand EX28 grapple saw
The versatile middle ground: a 0.28 m² grapple saw spanning the 12 to 25 tonne excavators most civil and vegetation contractors already own, with saw motor and chain options.
Dipperfox SC850 Pro stump grinder
The production model: 850 mm stump capacity, 900 mm depth and 43,000 Nm of first-gear torque for forestry blocks, highway and rail corridors and large development sites on 13 to 30 tonne carriers.
OMEF TRI pruning cutting bars
Comb-style shearing bars for 4 to 10 tonne excavators in 1.6, 1.9 and 2.2 m widths. All three cut the same 100 mm class; the difference is linear coverage per pass.
Powerhand EX36 forestry grapple
Wider tines and 0.36 m² of grapple volume for heavy brash and larger log bundles on 16 to 25 tonne excavators.
Powerhand EX36 grapple saw
The heavy rigid grapple saw: a 0.36 m² grapple, 1,000 mm bar and 650 mm cut for substantial forestry and clearance work, with 1,176 kg that must be counted in every lift calculation.
