Frequently Asked Questions

 The advantages of using GPS over laser are that you are not limited to operating close to the base station you can move up 4km from the Base. A field design surface can be loaded into the PC for the controller to allow the blade to follow in the field. This can be a flat plane, a combination of planes or even a ‘curved’ surface for more undulating fields. The only boundaries are the field boundaries.

The vertical accuracy of the GPS is typically 10 to 15 mm. Combined with other inaccuracies associated with land leveling, such as hydraulic lag, tyre flexing, field trash and clod size, it on a par with or better than laser systems used in agricultural land leveling.

Distance from the Base. The vertical accuracy is affected by the distance the rover is operating from the base station. However up to about 4 km from the base station there is very little change in accuracy.

Field Designs. 3D desing software such as OptiSurface Designer can be used to create simple designs with planes and ‘curved’ surfaces through to more complex ones with many multiple planes, banks etc.

Design Services  OptiSurface  or one of our many partners around the world can either create designs or help find a local designer who can do this for you.

Simple grading for building ditch pads and drains There is no need to have a field design on the PC for simple designs. The best part about this is this can be done from the tractor seat and these grades are stored in the PC so if you wish to return to this ‘design’ latter on it is easy.

AutoSteering and Leveling These functions can both happen together if you wish. This requires 2 Rover GPS’s to be mounted one for autosteering the tractor with the antenna on the bonnet of the tractor and one for controlling the blade with the GPS antenna on the bucket.

What sort of implements can GPS Machine Control be attached to? GPS can be used on any implement with a blade. Hydraulics on the blade need to be external (not three point linkage). Even landplanes and grader blades (with hydraulic wheel lifts) can be operated with GPS.

What sort of hydraulics are required? On larger later model tractors, such as Case, New Holland and John Deere the hydraulic remotes can be used to control the blade in automatic mode. With other brands of tractor a proportional valve will be required to operate the blade.

Can GPS machine control be used manually? Yes can be used either manually or in automatic operation. In the manual mode the operator follows the display on the screen to raise and lower the blade, in automatic mode the computer operates the hydraulics on the implement.
