Deere Puts Load-Sensing Hydraulics in 14-Ft. Backhoe

John Deere converted its popular 310 SL 14-ft. backhoe to a pressure-compensating, load-sensing hydraulics for the new L Series. Electronically controlled variable-piston hydraulic pumps facilitated adding the all-new 310SL HL heavy-lift. It and the 410L can deliver up to 25% more backhoe-lift capacity under normal conditions than comparable K-Series models. The hydraulic system also offers a new Lift Mode that can be engaged with a push of a button. The mode sets engine speed at 1,400 rpm and the machine maximizes hydraulic pressure for an additional 10% to15% craning capacity.

The L-Series meets U.S. EPA Tier 4 Final emission regulations with PowerTech Plus diesel engine on the 310L (93 hp), 310SL (99 hp), 310SL HL (110 hp), 315SL (99 hp) and 410L (113 hp), and a certified Tier 4 Interim Deere PowerTech engine on the 310L EP (70 hp).

A five-speed PowerShift transmission for smooth on-the-go clutchless gear changes achieves speeds up to 25 mph in the 310SL, 310SL HL, 315SL and 410L. The Autoshift option employs fuel efficient direct drive, lock-up torque convertor mode and automatically selects the best gear for a specific load.

The six new models in the L-Series lineup – the 310L EP, 310L, 310SL, 310SL HL, 315SL and 410L – are all built in John Deere’s Dubuque, IA, factory.

An Economy-mode choice is standard equipment, and limits maximum engine speed in both loader and backhoe operations when activated, to save fuel

Redesigned pilot towers have fingertip electrohydraulic (EH) controls for auxiliary hydraulics and extending dipper sticks

A new “palm-top” loader-control grip integrates controls for clutch disconnect, quick shift, auxiliary proportional roller and momentary front-wheel drive

State-of-the-art, multi-language monitor offers improved diagnostic information

Electronically controlled fan automatically changes speed as needed to control coolant temperature

Stacked coolers are hinged and tilt away from the radiator for core cleanout
