GNSS Land Leveling
System AG808

Plan a surface. Control the grade.

A GPS/RTK land leveling solution with a smart display terminal, GNSS receiver and ECU controller for guided grade control across day and night field work.

  1. 01

    Plan surface

    Set your target field design in the display terminal.

  2. 02

    Measure and guide

    GNSS provides real-time position and elevation, guiding the implement with precision.

  3. 03

    Control implement

    The ECU controller automatically adjusts the blade to follow the design and maintain the target grade.

One connected grade-control workflow.

AG808 brings positioning, on-screen grade guidance and implement control together in one field setup.

Smart Display Terminal
10.1-inch high-definition display with multi-touch instant response; dustproof, waterproof, shockproof, anti-magnetic interference, and stable performance.
Satellite Antenna
Receives positioning signals. Responsible for collecting satellite signals.
ECU Controller
Includes built-in wireless radio and hydraulic controller.
AG808 display terminal, satellite antenna and ECU controller
Supplied AG808 hardware imagery.

The field setup matters as much as the system.

Confirm these three items before ordering or commissioning AG808 for a specific machine.

01 / Design

Choose the target surface

Set a plane, single slope or dual slope. Record the benchmark and design values before work begins.

02 / Correction

Plan a reliable GNSS fix

The stated 30 km base-station radius is a maximum, not an accuracy guarantee. Check terrain, signal and local radio rules.

03 / Machine fit

Verify the complete installation

Confirm implement geometry, hydraulics, power, cable routing and manual override. Calibrate and test at low speed.

Review compatibility requirements

Details for a sound field setup.

Open the topics relevant to your machine and field before commissioning. Record the agreed design surface, correction source, machine offsets and installer checks in the job file so the setup can be reviewed later.

Correction source and base-station planning

The supplied presentation states a maximum 30 km base-station radius and says one base can serve multiple machines. This is an upper coverage figure, not a promise of equal accuracy throughout the radius.

Range and fix reliability depend on base placement, terrain, obstructions, radio environment, regulations and satellite visibility. Confirm the correction source before deployment and record it in the job file.

Compatibility and implement requirements

The supplied material lists telescopic leveling shovels, soil-loosening shovels, paddy-field leveling shovels and scrapers, and illustrates tractor-drawn and grader-style machinery.

Before purchase, confirm the machine, implement, mounting geometry, hydraulics, power, cable route, antenna position and manual override. Similar connectors do not prove compatibility.

For a compatibility check, share the tractor or grader model and year, implement type and width, hydraulic interface, available power, antenna position and correction-service details.

Installation and commissioning
  1. Inspect the tractor, implement and hydraulics before adding control hardware.
  2. Mount the GNSS antenna with a clear sky view and record its offset to the implement.
  3. Secure the terminal and ECU; protect cables from heat, pinch points and moving parts.
  4. Connect hydraulic control and verify raise, lower and manual-override directions.
  5. Enter dimensions, select correction, confirm a fixed solution and test at low speed.
  6. Record machine details, offsets, firmware, correction, calibration date and technician.

Safety note: This overview is not a substitute for the model-specific installation manual or trained installer. Do not operate automatic control until direction, limits, emergency override and safe clearances have been verified.

Calibration and final-grade verification

Calibration aligns the digital reference with the machine and implement. Use a stable benchmark, confirm antenna and blade offsets, verify correction and check the implement on a known surface.

Record the design mode, values, benchmark and correction source. Recheck after moving hardware, changing implements, altering hydraulics, updating firmware or seeing repeated grade differences. Verify final grade using the approved survey method.

Review the detail behind the workflow.

Use the technical documents and field-test report set to evaluate the system against your own conditions.

Practical planning questions.

Can AG808 create a slope instead of a flat field?

The supplied material describes plane, single-slope and dual-slope design modes. The operator enters the target values before work begins.

Does a 30 km base radius guarantee accuracy?

No. It is a stated maximum. Terrain, antenna setup, radio conditions and satellite visibility affect performance.

Which implements are shown as compatible?

The presentation lists telescopic leveling shovels, soil-loosening shovels, paddy-field leveling shovels and scrapers. Each machine and hydraulic interface still requires an individual check.

Check AG808 against your machine and field.

Send your machine model, implement dimensions, hydraulic details and intended correction source for a configuration review. Towaytek can then identify the documentation and configuration questions to resolve before quotation or installation.
