John Deere’s D-Series Knuckleboom Loaders Boast Higher Productivity and Fuel Efficiency
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 PowerTech™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, and auto idle, which shifts the engine into low idle when levers haven’t been operated for a few seconds, conserving fuel.
