Dozer pushing dirt on a construction site
CHCNAV TD63 Pro

Automatic dozercontrol.

Automatic 3D blade control for dozers — dual GNSS, a 100 Hz IMU and the DO-Tech algorithm holding ±20 mm while you push. Fine grade without a single stake.

What it does

The blade follows the model

Push, spread and fine-grade with the design surface driving the blade — automatically, in real time.

DO-Tech precision

Dual GNSS, a 100 Hz IMU and the DO-Tech algorithm hold the blade to ±20 mm — fine-grading accuracy while you push.

Automatic blade control

Real-time hydraulic adjustment at varying speeds and in any blade position. Finished grade, automated.

10.1" tablet

A big, bright operator interface with a deliberately simple calibration process — no surveyor needed.

Pilot & PVG compatible

Runs with Pilot and PVG dozer valve systems, plus multiple coordinate and design file formats.

Built for harsh sites

Rugged, durable components designed to shrug off dust, rain and the worst ground conditions.

30-minute calibration

A single IMU sensor and a quick calibration — the dozer is fine-grading the same day we install.
