Purpose Built Front Linkage
Cat wood chip and coal scoops have the unique capability of maximizing your production by both dozing and carrying a load with each pass. A purpose built hydraulic system is optimized for use with this work tool to maximize machine productivity and efficiency. Dual lift cylinders provide hydraulic lift capacity matched to the demands of the application.
Oscillating Rear Axle
The fixed front axle and oscillating rear axle ensures four-wheel ground contact for optimum traction and stability. The front axle is rigidly mounted to the front loader frame, while the rear axle is allowed to oscillate. This configuration allows the operator's view of the scoop to remain constant as the rear axle oscillates enabling the operator to maintain a smooth and properly graded work area in any underfoot conditions.

Operating Costs

The 834K has several features to achieve greater fuel efficiency:
  • Positive Flow Control Hydraulics – Provides only the hydraulic flow required by the implement and steering systems for improved fuel efficiency and greater rimpull.
  • ACERT Engine – Advanced engine controls maximizes power and efficiency.
  • Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
  • Lock-up Torque Converter – Transfers more power to the ground and optimizes fuel efficiency in all applications.
  • Advanced Productivity Electronic Control Strategy (APECS) – All new APECS transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.
Machine configuration, operator technique, and job site layout can impact fuel consumption.
  • Machine Configuration – Select the correct work tool and tire type based on machine application. Ensure proper inflation pressures.
  • Idle – Set the parking brake to engage Engine Idle Management System.


We can help you succeed by ensuring your 834K has design features to reduce your downtime.
