Hydraulic Pump Is Powerful, Responsive, Quiet

Designed for continuous, efficient and reliable operation, the forwarders axial piston hydraulic pump meets stringent requirements for noise, efficiency, controllability and durability. High load bearings are designed to ensure excellent reliability and long life. A spring assisted servo piston ensures rapid on-stroke performance, especially in low standby pressure conditions. The rigid casing design ensures that all internal forces are well supported. Hydrostatic swash plate balancing together with a rigid support mechanism enhances the power density and reduces noise emissions.

Valves Are Load Sensing, Pressure Compensated

The valve system has proven reliability in forestry applications with its fuel efficient load sensing pressure compensated technology. The valve has been given excellent simultaneous operating characteristics, which enable several machine functions to be operated responsively at the same time, regardless of the sizes of individual loads. Each section is designed specifically for the flow and pressure of the function, therefore optimizing machine functionality and fuel efficiency. Ramped and proportional crane functions saves mechanical wear and tear on boom structures. Steering sensors provide feedback through the IQAN control system to cushion stop points of the cylinders.

Tilting Hood Provides Easy Access

A forward tilting front hood assembly together with the side tilting cab design provide full access to the engine, hydrostat, and hydraulic components.

Better Diagnostics, Grouped Service Points

Simplified service and electronic diagnostics help to increase productivity and machine availability. Grouped lubrication points and lines reduce service times.

Easy Fluid Changes

Removable cover plates allow full access for cleaning and service. An electric refill pump to add oil into the hydraulic tank maintains system cleanliness by passing all added oil through the filtering system. A vacuum pump on the hydraulic tank reduces exposure to oil loss during service and repair.

Maximum Production, Comfortable Work

Spacious purpose built forestry cab with excellent sight lines to the work area. The forward positioned side posts provide maximum visibility for the loader working range. The ventilation system provides superb air flow for heating and cooling functions. Refined instrumentation and plenty of storage areas allow an uncluttered working environment.

State-Of-The-Art Controls

The forwarder utilizes the latest technology with CAN-Bus controlled IQAN, switch panels, and engine control. The IQAN MDL master control has a 165 mm (6.5 in) transflective TFT color display which includes excellent on‑screen diagnostics. Units are configured for English or metric display. Low effort ergonomic joy stick controls provide easy effort control of the loader functions. Loader functions are configurable for SAE or Forestry patterns. Loader control allows input into 3 selectable and adjustable operator interphases, plus a factory default. An automotive style, tuned hydrostatic propel system allows for all types of terrain and load characteristics.
