The agriculture family of laser products was developed by the pioneers in laser and grade control use in agriculture – Spectra Precision® – now Trimble Dayton. Accurate grade control ensures adequate crop irrigation or drainage for maximum yields, while reducing water and installation costs. The control of subsurface drainage machines results in improved drainage, high installation speed and the elimination of manual surveying and staking.

GL400 Series
Versatile automatic grade lasers for level, grade and vertical alignment

The Spectra Precision® Laser GL412 (single grade) and GL442 (dual grade) lasers are cost-effective, automatic self-leveling lasers that do three jobs—level, grade, and vertical alignment with a plumb.

GL700 Series
Innovative series of grade laser transmitters

The GL700 series grade laser gives you the right laser for the right job. From an economical single grade transmitter to an advanced, long-range radio remote controlled steep-grade transmitter.

LL400
Durable, highly accurate Spectra Precision® laser level

The fully automatic, self-leveling LL400 laser level sets a new standard in rugged reliability. Even in tough jobsite conditions, the LL400 consistently delivers reliable, accurate performance to increase your overall productivity and cost savings.

HV401-3
Horizontal Vertical Laser with exceptional accuracy

This high-accuracy, longer range laser is ideal for elevation control over large jobsites, as well as slopes on grade. The HV401 laser provides reduced setup, one-person operation, and faster return on investment.

GCS100
Single control system

The GCS100 Grade Control System is a single control system that controls the lift of the machine blade. The basic grade control system provides very simplistic controls and functionality that makes it very user friendly and improves productivity and accuracy of agricultural drainage and leveling equipment by up to 50%.

GCS300
Single control system

The GCS300 Grade Control System is a single control system that controls the lift of the machine blade. The GCS300 series provide improved productivity and accuracy of agricultural drainage and leveling equipment by up to 50%.

GCS400
Dual elevation or elevation and blade slope control

The GCS400 Grade Control System is a dual-control system that controls both the lift and tilt of the machine blade. The GCS400 series provides improved productivity and accuracy of agricultural drainage and leveling equipment by up to 50%.

AgGPS Field Level II System
3-D leveling system for water management

The Trimble® AgGPS® FieldLevel II system for water management can help keep water costs down and efficiently distribute water by maintaining grade.

Topographic Data can be collected via the AgGPS FieldManager™ display while using the AgGPS Autopilot™ automated steering system, or connected to an RTK receiver stand-alone. Using the AgGPS 442 GNSS or AgGPS 432 receivers you can collect detailed topography data, allowing you to precisely match scrapers to the survey data when it is time to level. With the FieldManager display you can run AgGPS Autopilot for accurate passes at the same time as FieldLevel II further maximizing the efficiency of your equipment.

With a topographic survey you can calculate a best-fit levelling and section the field using the AutoPlane functionality right on the display, or use the AgGPS MultiPlane software to design more complex scenarios in your office and import the design back into the FieldLevel II system.

When levelling the field, AgGPS FieldLevel II system will automatically raise and lower the blade on the scrapers based on the tractors location. Dirt will be moved to obtain the MultiPlane or AutoPlane design.

AgGPS MultiPlane Software
Land Leveling Design Software

The AgGPS® MultiPlane software takes field collected topographic data from any AgGPS Field Information System (for example, AgGPS FieldManager™ display) used with the high accuracy AgGPS 432 or 442 receiver.

The AgGPS MultiPlane software operates 3D land-form designs for the customer to evaluate. The end result is a cut sheet and a design control file that will assist the contractor in the land forming operation using the FieldLevel II system.
