The FJD H39 PRO 3D Dozer Control System brings intelligent, automated blade control to bulldozers across all major brands. Using high-precision satellite positioning combined with multi-type sensor modules, the H39 PRO captures real-time blade position and attitude data and automatically adjusts the blade through the valve control module — delivering centimetre accuracy from the first pass and eliminating grade checkers, rework and guesswork.

Automatic Blade Control — Smarter Earthmoving

The H39 PRO precisely controls the blade on every pass using the 3D design and real terrain. Operators can switch seamlessly between manual and auto modes, and one-tap blade lift handles turns, repositioning and obstacle avoidance without breaking the workflow.

Flexible Operation Modes

Import design files directly into the terminal and work in Design Files, Depth or Elevation modes — with full gesture controls (move, zoom, select, 3D rotate) making on-terminal operation fast and intuitive.

• Elevation Offset — Operate based on elevation offset values for accurate, consistent results.
• Blade Wear — Quick blade-wear calibration so accuracy stays uncompromised as the blade wears.
• Hold Slope — Extend specified slopes across the designed work area with stable, continuous guidance.

Masterless Solution

The H39 PRO fits masterless machines without mast installation or on-site transport — giving the operator an unobstructed view, a larger working range for the blade, and faster site set-up.

Real-Time 3D Visual Guidance & Task Visualization

The 10.1" LED touchscreen (8-core 2.2 GHz, 8 GB RAM + 128 GB ROM, IP68) displays the blade's exact position relative to the target surface with live cut/fill indicators — so progress and grade quality can be monitored straight from the cab.

Built Tough — Designed for the Worst Conditions

The control terminal is IP68-rated; the attitude sensor is IP67 and rated from -40°C to +85°C; and the wiring harness is durable down to -40°C — engineered for mining, civil and infrastructure sites where conditions are tough and downtime is expensive.

OTA Updates & Remote Support

Firmware updates are delivered over the air and remote diagnostic support is included — minimising downtime without an on-site technician visit.

Application Scenarios

• Railway track bed grading
• Mining area levelling and bench preparation
