Features

Electrohydraulic (EH) Controls

Interior view of wheel loader cab showing a steering wheel and a control joystick with orange buttons mounted on a black base

Electrohydraulic (EH) controls provide enhanced functionality, allowing operators to customize machine operations. This includes soft hydraulic stops and programmable joystick buttons. These features empower operators with increased productivity across various jobsite tasks.

Vision and Detection Systems

Interior view of a heavy construction vehicle cab showing an operator seated at the controls, wearing a hard hat and a high-visibility safety vest

Active jobsites present many operational challenges, including multiple machines, crew members, and bystanders. The John Deere Advanced Vision System (AVS) and SmartDetect™ can help enhance operator awareness to confidently navigate busy work areas.

Payload Weighing Systems

A front-end loader sits on a dirt construction site under a clear blue sky, holding a full bucket of soil raised slightly off the ground.

SmartWeigh delivers dynamic weighing without slowing down the job—no workflow interruption or boom reset needed. Easily viewed on the onboard monitor and integrated with the John Deere Operations Center, it’s available as a factory or field‑installed option.
