The Konrad Highlander is a wheel harvester developed for steep terrain, working where other harvesters give way to cable cranes, in two versions: the four-wheel HL10-2 and the six-wheel HL20-2, both with a 212 kW FPT engine and a Woody harvester head.

Built for steep terrain
Developed specifically for steep terrain, the Highlander works where other harvesters give way to cable crane systems. Automatic level compensation keeps it stable on the slope, and an optional traction winch supports it on steep ground.

Crane and cab turn as one
The HL24 crane, with 240 kNm of lifting torque and a 10.8 m reach, turns endlessly together with the cab, and carries a Konrad Woody WH50-1 or WH60-1 harvester head.

Konrad HL10-2

The four-wheel Highlander, as suited to thinning as to final felling: a short wheelbase with two-wheel, four-wheel and crab steering, and four-wheel drive with an engageable hydraulic differential lock.

Drive: 4×4
Power: 212 kW
Pulling force: 235 kN
Operating weight: 22,500 kg

Konrad HL20-2

The six-wheel Highlander, mainly for medium to big timber: a portal tandem axle at the front, a balanced weight distribution for lower ground pressure on soft ground, and 272 kN of pulling force.

Drive: 6×6
Power: 212 kW
Pulling force: 272 kN
Operating weight: 25,500 kg

Harvester heads

Both Highlanders work with Konrad’s own Woody harvester heads: the Woody WH50-1 or the Woody WH60-1. The crane and the cab turn together, endlessly, on the slewing ring.

Built for steep ground

The Highlander climbs and drives with a synchronised stepping and driving motion, and automatic level compensation keeps the machine stable and its slewing moment constant on the slope. The HL20-2 adds telescopic extension feet. The TW90-1 traction winch, an option integrated in the machine, supports driving on steep terrain and can also be used as a rigging winch.
