LS200 GNSS land leveling system working with a trailed scraper in a farm field
The LS200 Land Leveling System is an RTK-based GNSS land leveling system for tractors, graders and scrapers. Instead of relying on the operator’s eye or a laser beam that needs a clear line of sight, it uses satellite positioning and inertial fusion to locate the implement in real time and automatically raise or lower the blade, cutting high spots and filling low spots to a centimeter-level grade. The result is a flat or evenly sloped field ready for sowing, transplanting, irrigation, ridge forming and spraying.
By producing a more uniform soil surface, the LS200 helps save water, save land, save fertilizer and increase grain output: irrigation water spreads evenly without ponding or runoff, topsoil is moved less, seed and fertilizer land at a consistent depth, and crop establishment becomes more even.
The LS200 combines a base station, a GNSS+INS receiver mounted on the implement, an in-cab controller, and the hydraulic lifting system of the grader or scraper.
Satellite and inertial positioning: The receiver tracks Beidou, GPS and GLONASS satellites, fused with an inertial navigation system (INS) to keep position and attitude stable even in signal-shadowed moments.
RTK differential correction: The base station sends real-time kinematic (RTK) carrier-phase differential corrections, removing satellite errors and delivering centimeter-level horizontal and elevation accuracy.
Target surface comparison: The controller compares the actual blade height with the designed target plane or slope; a target surface can be created quickly from a single point.
Automatic hydraulic adjustment: Hydraulics raise or lower the blade continuously as the machine moves, holding the designed grade across every pass.
The LS200 uses RTK real-time kinematic carrier-phase differential technology to provide centimeter-level horizontal and elevation positioning accuracy. The control accuracy is configurable to match the requirements of different field scenarios, with a maximum control accuracy of up to 1 cm.
Centimeter-level horizontal and elevation positioning under RTK correction.
Adjustable control accuracy for light finishing, heavy rough grading, and different soil conditions.
Consistent grade on both flat planes and sloped land.
Heavy-duty implement frame and wide leveling blade
The LS200 is built to be quick to set up and easy to judge by the operator, without relying on experience alone.
GNSS+INS fusion: Satellite and inertial data are fused, and the target surface can be created quickly from a single point.
Automatic height calibration: The blade/bucket height is calibrated automatically before work starts.
Elevation error heat map: A visualized heat map of elevation error shows the leveling effect at a glance, so unfinished or over-cut areas are easy to identify.
Optimized auto-leveling algorithm: The leveling control algorithm is deeply tuned to reduce abnormal working conditions such as digging pits (pitting) and blade bounce (“flying shovel”) during the pass.
Trailed chassis with dual wheels and reinforced drawbar
The LS200 leveling controller supports both graders and scrapers, and can be adapted to mainstream grader and scraper models on the market. It is not tied to one implement type: working width, blade configuration and tractor power match can be selected according to field size, soil conditions and your existing machine fleet.
Beyond the implement-level control, the LS200 platform supports farm-scale precision operation:
Multi-constellation, all-weather operation: Beidou-based, compatible with GPS and GLONASS; satellite signals are not blocked by dust, fog, ridges or obstacles, so work can continue day and night in wind, dust and light rain.
Long-range shared base station: One base station covers a radius of up to 30 km, without repeated relocation, and can guide several machines working at the same time.
Guidance and field management: Built-in work-line and route design keeps passes straight and overlap low; it also supports ridge forming and spraying guidance.
Cloud data and expansion: Field data can be uploaded to a cloud platform for remote viewing and analysis, and the system can be upgraded to a full tractor auto-steering solution later.

The LS200 is an RTK GNSS+INS land leveling controller for tractors, graders and scrapers. It receives satellite differential corrections, compares the implement height with the designed target surface, and automatically adjusts the hydraulics to level or slope the field to a centimeter-level grade.
RTK carrier-phase differential positioning delivers centimeter-level horizontal and elevation accuracy. The control accuracy is adjustable for different scenarios, with a maximum control accuracy of up to 1 cm.
GNSS provides satellite position and elevation, while the inertial navigation system (INS) tracks implement attitude and motion. The fusion keeps positioning and height stable between satellite fixes and lets the operator create the target surface quickly from a single point.
It is a visual color map on the in-cab display that shows where the field is above or below the target grade, so the operator can see the leveling effect immediately and locate unfinished or over-cut areas without guesswork.
The system supports graders and scrapers and can be adapted to mainstream grader and scraper models on the market. Tell us your implement type, width and tractor model for a matching configuration.
One base station covers a radius of up to 30 km and can guide several working machines at the same time, reducing cost per machine and speeding up large-scale land preparation.
Yes. The platform already provides guidance lines, elevation feedback and cloud field data, and it is built to expand into a full tractor auto-steering solution when you are ready.
Because it relies on satellite signals rather than a visible laser line of sight, the system is designed for all-weather, 24-hour operation, including night work and light rain or dusty conditions.
