Control the ride and load with Auto Ride Control
Auto ride control
Overview
Auto ride control is based on an adjustable ground speed setting. When the set ground speed is reached, ride control will be turned on, creating a smoother ride for the operator and reducing spillage from the bucket. When the machine drops below the speed setting, ride control will be turned off, allowing for maximum productivity with the loader. Auto ride control is now the only ride-control option. This option eliminates the need to manually turn the feature on and off during load and carry applications, boosting operator ease of use.
Benefits
- When activated, front loader cylinders function as a shock absorber, smoothing the ride over rough terrain and reducing material spillage
- On/Off functionality is controlled by ground speed and can be adjusted by the operator in the cab’s display monitor
Additional Details

- Speed selectable in monitor
- Turns on ride control when ground speed exceeds setting in monitor
- Turns off ride control when ground speed drops below adjustable setting
Set it and go to work with AutoShift
AutoShift transmission setting
AutoShift allows the operator to be more productive by keeping the unit operating at its peak performance. When enabled on the sealed-switch module (SSM), AutoShift automatically shifts the PowerShift™ transmission to the appropriate gear, enhancing the operator experience. Simply set the control lever to the highest gear desired, and the transmission will optimally shift based on engine rpm and ground speed.
- The transmission will optimally shift based on engine rpm and ground speed
- Improves the operator experience during transport or load and carry applications
- Smoothest shifting automatic transmission in the industry
- Improves operator comfort by reducing the number of times the transmission control lever (TCL) needs to be actuated during Loader operation

New Pressure-Compensated, Load-Sensing PCLS Hydraulics
PCLS Hydraulics
Pressure-compensated, load sensing (PCLS) hydraulics, provide better multifunctioning, smoother machine control, and up to 15 percent greater craning capacity with Lift Mode, collectively providing a distinctive customer experience and unmatched machine reliability. PCLS are highly valuable for Underground customers due to its productivity, lift capacity, quality and reliability. The machine delivers all the advantages of PCLS hydraulics in the 14-foot digging-depth category, enabling operator efficiency and productivity through improved multifunction control. For additional performance, the 310SL HL has up to 5-percent-more rear-craning capacity and 10 more net horsepower.
- The variable displacement axial piston pump creates hydraulic flow on demand, increasing hydraulic efficiency, decreasing fuel consumption, and lowering the daily operating cost for your customer.
- Selective flow auxiliary rate selection has been moved into the monitor, eliminating the need to get out of the cab and adjust a manual knob on all PCLS machines.
- Buttons for the horn, selective flow, auxiliary proportional roller, and extendable dipperstick have been incorporated into the pilot controls.
- The 310SL HL uses the proven hydraulic architecture of the 410L, including the same hydraulic pump and valves.
- The 310SL utilizes the same rear valve as the 310SL HL and 410L, for improved swing metering and return-to-trench accuracy
- The PCLS system enables excellent multifunctioning ability at all engine speeds.
- Faster cycle times improving trenching productivity by 16 percent over the prior design.
- Trenching operation can be conducted at a lower engine rpm, reducing fuel consumption and jobsite noise.
- Precision mode reduces hydraulic flow by 55 percent, allowing accurate, detailed backhoe work to be performed without sacrificing overall hydraulic-lift performance.
Powerful John Deere PowerTech™ EWL Engine
PowerTech™ Plus engine
The engine has been updated to the John Deere PowerTech™ EWL that eliminates the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) system. Underground customers will appreciate the increased power, improved torque, and greater reliability compared to the previous design.
