Hydraulic Land Leveling Control — Automated Blade Guidance for Any Terrain

The W20 controller outputs PWM signals across 8 channels to drive hydraulic implements directly, adjusting blade position continuously based on GNSS positioning data. The intelligent soil unloading function monitors load distribution in real time — automatically redistributing excess soil to prevent engine stalling and reduce fuel consumption during heavy passes. Operators no longer need to manually manage blade depth through changing terrain conditions.

3D Terrain Mapping for Smarter Cut-and-Fill Planning

Before a single pass begins, the W20’s Smart Operation feature generates a true 3D terrain map with color-coded elevation data from one survey run. The system automatically calculates the optimal leveling model to minimize cut-and-fill volume — reducing the total number of passes required and keeping fuel and time costs down across the full job.

Compatible with the Implements Already on Site

The W20 supports horizontal, single-slope, and dual-slope leveling modes and works with AllyNav’s telescopic land leveler at 2.4–4 m, curved-beam scrapers, scraper loaders, paddy field levelers, bulldozers, and graders. The GNSS antenna tracks GPS, BDS, GLONASS, Galileo, QZSS, and IRNSS frequencies, with third-party CORS compatibility for cross-regional operation without internet dependency.
