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 Deeres Dubuque, IA, factory.
