Choosing a Model
Two questions decide the right model: how thick is your largest branch, and how much horsepower does your tractor have?
- 1
Maximum branch diameter
VOLVERINI chippers come in four groups: 10, 15, 21 and 25 cm cutting capacity.
- 2
Tractor power
Cutting at maximum diameter needs the top of the power range. PTO must run at 540–1000 rpm.
- 3
Mobile or stationary?
Work on the move with a tractor in forests and orchards, or choose an electric stationary version for factories and yards.
| Model | Max. dia. | Tractor power | kW | Hydraulics | Oil tank |
|---|---|---|---|---|---|
| AY400 | 10 cm | 25–50 hp | 20–40 kW | Not needed | — |
| AY600 | 15 cm | 45–75 hp | 30–55 kW | At least 2 hydraulic ports | 20 L (T model) |
| AY900 | 21 cm | 60–100 hp | 45–75 kW | At least 2 hydraulic ports | 30 L (T model) |
| AY1000 | 25 cm | 60–110 hp | 45–80 kW | At least 2 hydraulic ports | 30 L (T model) |
| AY1000 HFC | 25 cm | 60–110 hp | 45–80 kW | Conveyor: electric control | 30 L |
If your tractor is older and its oil pressure is below factory spec, or it lacks at least 2 hydraulic ports, choose the “T” model with its own oil tank and pump. Every model can be fitted with an electric motor.
What are wood chips used for?
Wood chips are the pieces produced when branches, logs and timber are run through a chipper. VOLVERINI disc chippers turn idle woody material into the first step of recycling.
- Organic fertiliser: keeps soil moist and supports organic farming
- Cheap energy: heat and power that compete with gas and diesel
- Raw material for pellets, briquettes, paper, chipboard and flooring
- Forest clearing: lowers wildfire risk and fungal growth
- Landscaping, mulching and animal bedding
