Grade control


O’Connell Drainage Plows is pleased to supply our customers with multiple options for GPS and Laser grade control.

GPS Single Control Options

Ag Leader Intellislope™ is an accurate Ag Grade GPS option for controlling either slope or elevation. The Ag Leader InCommand 1200 screen is Ag Leader’s top of the line control system that can operate all of Ag Leader’s technology on your farm including Intellislope™. 

Trimble Water Management can be used by contractors or farmers to minimize water costs and efficiently distribute water by maintaining grade—helping farmers see improvements in yields, water usage, and farm productivity. Choose from a variety of products based on your irrigation or drainage needs.. 

AMW Machine Control is an extremely accurate Construction Grade GPS option for controlling slope and/or elevation. The AMW Machine Control system can be used to control construction equipment, to the precision needed for DOT Roads and Ditches. The AMW Pipe Program is a construction grade tile software used in self-propelled tile plows and trenchers.

If you have RTK signal, both AMW Machine Control and Ag Leader products can utilize your existing RTK Globes.

GPS Dual Control Option

Trimble Water Management or AMW Machine Control can control slope and elevation at the same time allowing for more precise tile placement than controlling just slope or elevation. Both programs are used in self-propelled trenchers, tile plows, and cable plows.
