959MH Tracked Harvesters


Simple and smart.

With the 909MH Tracked Harvester, we have combined the best of both worlds by giving you many of our time-tested, proven features, such as our best-in-class harvesting heads, while adding to your comfort and productivity with beefed-up engine horsepower and a cab that will make you feel like you are relaxing rather than working. Loggers meet luxury.

Key Features

  • Tier 2/EU stage II
  • Sealed switch module
  • Standard variable speed reversing fan

Productivity

All 900M models have a variable speed, hydraulically driven, reversing fan. The directional valve’s solenoid reverses the rotation of the fan, this feature prevents debris from building up on the coolers and can be set to automatically reverse or manually reverse at the touch of a button on the SSM. The reversing time interval is adjustable in the PDU. This valve also contains a reversing fan pressure test fitting.

The 900M and MH models have dual swing motors, this feature is important to harvester operations where the machine spends much of the time swinging to process a log. The dual drives offer a productivity increase due to the increased capability, located inside the swing housing is the rotary manifold this new location is much more accessible, so if service is required, the downtime is greatly reduced. The upper structure and undercarriage can be locked from rotating by pressing the swing lock button on the Sealed Switch Module (SSM), It can then be unlocked by simply pressing the button again.

Cab Comforts

The 900M and 900MH all use the same cab structure. One of the most noticeable changes with the cab exterior is the redesigned light package. There are six independent 24-volt flood lamps across the front cab brow. The top brow consists of four work lights and two centre drive lights, which allows the operator greater freedom to manipulate the lighting direction for maximum visibility. The lights above the cab door are split between one flood light and one drive light. The premium Light Emitting Diode (LED) system enhances the lighting package even more ensuring productivity can be maintained at a high level even at night.

The advantages to EH joysticks are numerous. There are no oil lines into the cab, which simplifies the overall hydraulic system. These machines also have low joystick effort. In a conventional pilot operated system, the operator has to develop enough force to overcome the force required based on pilot pressure. In an EH system, it is only required to develop the force to move the stick itself. The speed, acceleration, and deceleration of function speeds can all be adjusted to fit an operator's preference. This can be done globally or function by function and stored by operator ID in the interface. A setting for truck drivers who are loading is commonly stored onto the system for safe efficient loading

Maintenance

Service access on the 900M/MH carriers remains similar to the K-Series machines. One button on the SSM raises the enclosure on the right side of the machine for easy access to the daily service checks around the engine and hydraulic system. Four handholds allow for easy manoeuvrability between the cab and engine enclosure. The service access walkway remains standard on levelling units and is an option on non-levelling machines. This walkway allows the operator to easily check daily service points without having to continuously climb up and down the machine.
