WM-FieldForm allows for mapping and implement control with new displays that have faster auto-design features
PTx Trimble, now a part of Agco, introduced a new digital system in mid-November for creating topographical field maps, drainage plans and the necessary software and hardware to control implements to carry out those plans.
WM-FieldForm is capable of controlling a single scraper to shape field surfaces. It is the first water management system from the company to be based on the Precision-IQ field application software used in its GFX-1260 and 1060 displays. It allows for improved visualization and faster auto-design features, according to the company.
“We started our ‘farmer first’ with a single scraper,” says Scott Azbell, worldwide water sales manager at PTx Trimble.

The U.S. Department of Agriculture’s crop production and world agricultural supply and demand estimates reports were released July 11 with the main focus on the wheat, corn and soybean estimates.
“Our next phase will be sub-surface drainage. Then we’ll come back in and go after the contractors with dual and tandem scrapers — two scrapers hooked front to back or side to side.”
Farmers can use WM-FieldForm to create topographic surveys of fields using RTK measurements with boundaries, interior points and calculations to report true acreage, using tools such as PTx Trimble’s WM-Survey II app.
Survey data can then be imported into WM-Form design software to create field surface drainage plans using Multiplane technology to define primary and cross slopes, orientation and preferred grades for more complex field requirements.
An RTK guidance system is necessary for WM-FieldForm to work.
“There are a bunch of different signals out there, but RTK is the only one that has vertical accuracy,” says Azbell.
“We need the vertical accuracy to be within two centimetres.”
The system allows farmers to do all of the work necessary to carry out a drainage operation from start to finish, which includes creating a drainage plan and getting the tractor and scraper to actually carry out that plan.
“We’ve been testing this for about five months now, making sure we got all the bugs out before we actually released it,” he adds.
“It’s very intuitive. The guys that were doing beta and alpha testing walked right through it. I say we wrote the code right because it’s user friendly. It does complicated work, but it’s simple to use.”
WM-FieldForm requires PTx Trimble’s newest GFX1260 or 1060 monitor to work. The change in software format the brand moved to a few years ago won’t allow it to work on older monitors.
“The displays today are Android based, the others were not,” says Azbell.
“You can use Android apps with the Survey II as a way to get your own (topographical) mapping, so we can use that on this display.”
Aside from the monitor and receiver on the tractor, the system relies on a receiver on the scraper as well.
