The CR600 can be used as a hand-held or rod mounted receiver for a wide range of applications, including measuring cut and fill, leveling forms and footers, setting grade and measuring elevation changes. In addition, the CR600 can be used as a machine control mounted receiver for use on a backhoe, small excavator or skid steer loader. The CR600 is an ideal low-cost entry to machine control productivity.

LR30 Grade Display Receiver

For use on many types of grading and excavation equipment including dozers, backhoes, excavators
and trenchers. Five channels of grade information plus directional out-ofbeam indicators. Three
selectable accuracies meets job tolerances from rough grading to final finishing.

Grading and excavating display receiver.
 5 channel display - easier to find on-grade
 3 deadband setting to optimize accuracy v speed requirements
 2 Brightness settings to optimize visibility and reduced eye strain
 7" photocell height for large laser reception

LR50 GRADE DISPLAY RECEIVER
Built-in blade tilt indication helps the operator keep the blade level for increased production and accuracy. Can be programmed
to match an existing or known grade for slope matching operations. Center On-grade provides an equal amount of grade information
above and below on-grade. Use on dozers, graders, scrapers, and box blades. Built-in plumb indication for quick and accurate
grade checking for backhoes and excavators. Offset On-grade provides more information above grade using the entire receiver for
productive excavation. Up to six channels of grade information plus directional out-of-beam indicators. Three selectable accuracies
for each ongrade location. Use as a stand-alone display receiver or combine with the CB25 control box to create affordable
automatic blade control for dozers.

The robust Trimble LR400 receiver combined with the GL700 transmitter is designed specifically for earthmoving applications performed with larger machines like dozers, scrapers and excavators. The receiver features center on-grade for use with dozers and scrapers and an "excavator mode" for use with excavators and backhoes. Using the excavator mode, more above-grade information is displayed making it easier for the operator to lower the bucket and cut to the correct grade.

Features & Benefits

• Large LED display arrows indicate "high" or "low" with amber lights and "on-grade" with green lights so the operator can quickly and easily move the cutting edge to a desired elevation, especially on larger machines such as excavators, dozers and scrapers, for improved productivity.
• Adjustable accuracy bandwidths and distinct modes for specific applications and equipment provide flexibility to meet the machine needs and the accuracy requirements of the job.
• Selectable "on-grade" location and accuracy indicators provide improved efficiency and allow customization of the receiver to each unique application.
• Rugged, waterproof magnesium housing withstands tough jobsite conditions.
• Powered using its own battery or using the machine's battery.

Spectra Prince Albert 360° Receiver detects and provides 5 or 7 channels of grade information, with vertical sensing range of 7.3", mounts on tubing from 1 1/2" to 2" dia.

GradeEye consists of a portable laser receiver mounted on a mast on the machine that receives information from a laser transmitter to display on and off grade. The receiver can be used with a variety of Laser transmitters from the laser level section.

The low-cost, quick-mount EasyGrade-- with its 13 cm (5 in) laser-detection height and 240° reception angle-- allows you to check grade from the cab. The quick-release magnetic attachment is tough enough to hold under the demands of most digging conditions but is easy enough to remove with just one hand.

GGradePro® Using the GradePro Receiver, you don't need a dedicated "grade checker" on the job. The Receiver--with its 210° reception angle--lets you: Be more productive-get to grade quicker so you save time and fuel Get professional results-improve accuracy and reduce rework Be more efficient-check grade from the cab and keep your machine digging Be more profitable-save material and use your equipment more efficiently.
