John Deer’s D-Series Knuckleboom loaders deliver higher productivity and fuel efficency
Posted on July 2nd, 2010
John Deere Construction & Forestry’s new Knuckleboom Loaders are bulked up over their predecessors for improved durability and performance.
Productivity-increasing features include the fuel-efficient John Deere 6068 Tier 2 PowerTechTM engine with a high-pressure common rail electronic fuel injection system for improved cycle times and new Pressure Compensated Load Sensing (PCLS) hydraulic pumps with a dedicated swing pump to deliver responsive, efficient hydraulic power to all functions.
Other updates to the D-Series 335D and 437D Knuckleboom Loaders include:
- Heavy-duty swing bearing and pinion with taller gear teeth reduce the torque load on each tooth for robust performance and unsurpassed reliability
- New improved hydraulic manifold
- New standard display monitor delivering the same information as earlier models with the addition of engine diagnostic information
- Auto idle, which shifts the engine into low idle when levers haven’t been operated for a few seconds, conserving fuel
- All John Deere cylinders
