OverviewThe Moritz Fr70/75 is a second-generation remote-controlled tracked mini felling tractor designed for forestry operations, forwarding and as a multipurpose off‑road implement carrier. The concept combines proven tracked-felling elements with powerful multipurpose carrier features and includes major technical upgrades: new Deutz 4‑cylinder engines, advanced hydraulics and full radio remote-control functionality.
Key benefits & applications- Designed for sustainable reforestation: site preparation for sowing/planting, planting and young-stand maintenance.
- Multipurpose carrier: quick-change cable winch system and front/rear 3‑point hitch (Cat. 1) for mounted implements.
- Suitable for felling, forwarding, mulching, planting, sowing-strip milling and general off‑road maintenance on slopes and sensitive soils.
Technical highlights (summary)- Deutz 4‑cylinder diesel engines (Fr70 and Fr75 variants).
- High ground clearance: 320 mm for travel over roots and stumps.
- Low ground pressure: approx. 0.28–0.33 kg/cm² to protect substrate on wet ground.
- Hydraulically variable running gear width (expandable by ~400 mm) with options for 250 mm or 300 mm track widths; running gear length 1,650 mm.
- Separate hydraulic circuits for driving, on‑board functions and high‑performance power hydraulics.
- Full vehicle and winch control via ergonomic radio remote control (engine start/stop, speed ranges, winch, PTO, lights, etc.).
Attachments / Implements (examples)- MAX forestry cutter / MAX forestry mulcher (approx. 1,200 mm working width; various tool and flap options).
- Sowing-strip mulcher / sowing-strip cutter driven mechanically by PTO, milling depth up to 200–250 mm depending on specification.
- Forestry mulchers in multiple widths and tool types, with hydraulic flap options.
- Planter (Plantomat) with 50‑plant magazine and radio control; automated planting sequence with milling wheel and planting spade.
- Stump grinder (hydraulic supports, swivel ±45°, working depth up to ~620 mm, wheel Ø ~600 mm, carbide chisels).
- Auxiliary front cable winch (10 kN) and hydraulically driven traction winch for steep terrain operations.
- Personal protection screen for safer felling operations.
Operational features- Ergonomic radio remote: emergency stop, engine throttle, drive & steering (two speed ranges), reversible fan control, drift compensation for slope work, winch control, shield control, width adjustment, PTO on/off, auxiliary valves, horn and lighting.
- Proportional drive with two speed stages (0–3 km/h and 0–6 km/h) and gradual final speed preselection.
- CLEANFIX reversible fan (standard) for high cooling performance and automatic cleaning.
