SR21 Survey Receiver for Agriculture Grade Control

The SR21 linear survey laser receiver is the latest component in the Trimble GCS21 plug-and-play grade control system for today's agriculture environment. Designed for use with a wide range of agricultural and construction machines> for land leveling, drainage, water management and earthmoving applications, the innovative laser receiver mounts to the blade to provide grade control and topographic elevation information to the operator.

Features include:

• long reception height
• multi-strike laser rejection
• lost beam indication
• expandable plug-and-play operation over a Controller Area Network (CAN)

3 Modes of Operation Standard

• Survey:  Ideal for collecting information on your field, elevation data can be easily downloaded to a laptop or hand-held computer allowing you to calculate more precisely the amount of material to be moved. In Survey mode the SR21 tracks and records the elevation of the laser beam as the machine travels over the field.
• Indicate:  Increase productivity with or without using full automatics. Indicate mode shows the blade position relative to the design elevation, providing the operator with the exact amount of cut or fill needed to get to the design elevation.
• Control: Automatic control allows you to get to grade faster with fewer passes, increasing production, productivity and profits.  In Control mode the operator selects the position of a laser to automatically control a machine blade to grade through its hydraulic system.
