Overview of Braking Behavior
The John Deere 310L backhoe loader does not rely on independent front-wheel brakes. Instead, the braking behavior hinges on the engagement of four-wheel drive (4WD). When the machine is set to 4WD and both brake pedals are applied, braking force is transmitted through at least three wheels and the open front differential assists in distributing stopping power across the drivetrain.
Operational Conditions for Four-Wheel Braking
This capability is conditional and linked to gear selection within the transmission. Specifically, the automatic engagement of 4WD upon braking only functions when operating in higher forward gears—typically fourth or fifth gears. In lower gears or drive modes, that automatic front-wheel braking feature may remain inactive, even if the option exists in the machine’s software configuration.
Development Context and Machine Evolution
John Deere’s L-Series backhoes, including the 310L, emerged as refined successors to previous K-Series models. They introduced pressure-compensated load-sensing (PCLS) hydraulics for improved multifunction performance, a standard that carries through to models like the 310SL and 410L. These models also added features like precision mode for delicate control, AutoShift for smooth clutchless gear changes, and optional ride control for smoother loader travel over rough terrain . Four-wheel drive remains an on-demand mechanical front-wheel-drive (MFWD) system, engaged via a switch on the loader control panel .
Technical Terms Defined
A grade operator once needed to move a full backhoe-loader across sloped terrain while keeping braking smooth and stable. By enabling the automatic 4WD braking feature and shifting into higher gears, the machine halted quickly and confidently on loose gravel—demonstrating the system’s real-world safety advantage for road travel or hilly conditions.
Recommendations for Users
John Deere’s 310L Loader Backhoe employs a drivetrain-mediated braking strategy, not independent front-wheel brakes. Four-wheel braking activates automatically only under certain gear conditions and when MFWD is engaged. Coupled with a robust PowerShift transmission and advanced hydraulic and control features, it delivers reliable braking and traction—especially useful on roads or softer ground. Proper gear selection and maintenance are key to harnessing this feature safely and effectively.

Technical Terms Defined
- 4WD / MFWD (Mechanical Front-Wheel Drive): A drive system activating front wheels momentarily for added traction.
- Automatic 4WD Braking: A feature where the front drive system engages upon application of the brakes, but only under specific conditions.
- Differential: A drivetrain component that allows wheels to rotate at different speeds, critical in braking dynamics here.
- Engine: Tier 4 Final PowerTech 4.5 L diesel producing about 93 hp @ 2,200 rpm
- Operating Weight: Approximately 14,600–15,000 lb (6,650–6,800 kg)
- Transmission: PowerShift with 5 forward gears (higher gears enable automatic 4WD braking)

Recommendations for Users
- Explore the machine’s menu options to verify if automatic four-wheel braking is activated—consult technician if unclear.
- On road or firm terrain, shifting into higher gears enhances braking capability significantly due to the drivetrain engagement.
- During low-speed or compact site work, treat braking behavior as primarily reliant on rear-wheel stopping—adjust planning accordingly.
- Keep brake components well-maintained (bleeding hydraulic lines, replacing worn pads or discs) to ensure consistent pedal feel and safety .
