Mechanical Front Wheel Drive (MFWD) front axle

Overview

Mechanical Front Wheel Drive (MFWD) with limited slip differential.  The main MFWD on/off control is mounted on the RH console.   

• Limited slip front axle delivers 65% of available power to the tire with the best traction for true all-wheel-drive pulling power.
• Completely sealed axle has no breathers to maintain or service, promoting reliability (axle breathers can be susceptible to water and/or dirt intrusion).
• The machine will automatically disable the MFWD in 4^th gear to reduce tire wear. 
• Extend tire tread life with Momentary MFWD for ‘on the fly’ activation.  Controlled with a touch of a button on the loader lever.   Great for engaging a pile or briefly powering through sticky or slippery terrain. 

Powershift™ transmission

Overview

John Deere continues with its PowerShift™ Transmission and can be manually shifted by use of the transmission control lever.  4 forward, 2 reverse gears.

• Heavy duty transmission oil filter standard on all machines for increased reliability
• Hydraulically actuated clutch packs for smooth shifting and reliable performance under all operating conditions and loads
• Easy to reach twist grip Transmission Control Lever (TCL)
• More control at your fingertips. Repetitive tasks like shifting and changing direction can be done with one hand, right next to the steering wheel

John Deere PowerTech™ EWL Engine

Overview

The John Deere PowerTech™ EWL that eliminates the need for a diesel particulate filter (DPF) and exhaust gas recirculation (EGR) system.  Underground utility customers will appreciate the increased power, improved torque, and greater reliability compared to the previous design.  For models 310 P, 320 P, 410 P, 710 P. 

• EPA Final Tier 4 (FT4)/EU Stage IV emission certified. 
• 3–7 percent net horsepower increase (over Power Tech Plus configuration) with improved torque curve. 
• Removal of the exhaust gas recirculation (EGR) system and components (plumbing, cooler, and sensors).  
• Simpler two-valve cylinder-head design. Redesigned and improved fuel-filter location enables easy access when changing filters. 
• Does not require a DPF, reducing maintenance costs on the aftertreatment system.

310 P-tier backhoe

Overview

The open center control valve and pump combination has been used on Deere backhoes since 1997.  This field-proven system has served the product well over its lifetime, providing such benefits as high contamination tolerance, excellent swing control, open center pressure/force control, operator “feel”, and excellent multifunction performance as compared to other open center systems in the marketplace.   

The 310 P is configured with a single gear pump (28 GPM). 

• Very efficient system type for high productivity digging application.   
• Continuous oil flow for cooling and filtration, even with all functions in neutral.  Cleaner, cooler oil means improved system life and less downtime.   
• Inherent load feedback to the operator.  Lever position with an open center system delivers a certain force level to the cylinder.  Open center can provide a level of “feel” for experienced operators when fine metering through the cut searching for an object in the ground.
