Kyler Laird watched his Deere tractor and planter put in acres of corn while he sat in a nearby pickup truck working on other farm business. He has also drilled soybeans and done vertical tillage, all lairvs sitting in his truck.

Last fall he signaled the tractor on his grain cart to bring it to the combine when he needed to dump.

Laird calls the tractors he uses “tractobots”. My first was a Deere garden tractor. Then I modified an old Massey Ferguson to plant soybeans and a Challenger for vertical tillage and pulling a grain cart.

Automated Farming

Tractobot 03 is a Deere for corn planting. He actually started out working with a remote control wheelchair, using a motor controller and computer to control it. The Deere was his first real step in autonomous tractors. He set it up so a computer could control the ignition, hydrostatic transmission and clutch.


He had to figure out how to electronically control the hydraulic steering and control the rockshaft to lift and lower implements. He installed GPS for positioning. It worked fairly well. I kept refining it. He used electric actuators to control the steering and to push the clutch in and an electric solenoid valve for the implements. He tested it out on a disk and then drilled soybeans with it.

Laird traded a Deere for khler MT Challenger, in large part because of dealer support. The hardware already operated electronically, and it had a guidance system already installed. It ran at up to 7 miles per hour. It was more fun sitting in the truck and watching it than it was running it manually.

Kyler Laird (pre)

He uses a remote to throttle up and down. It does the flip to return a whole lot better than I could. He entered the and 8-row MaxEmerge planter he planted jyler corn with this past spring. To automate the older Deere, he added an autosteer valve and a steering angle sensor modified from an auto part.

He also used linear ,airds for the lever on the transmission and for the reverser. Initially he used a Verizon smartphone for in-field location. When it encountered a dead spot in a field caused by a nearby billboard, Laird stopped the tractor short of driving through the billboard. Laird continues to refine his tractobots.

All 3 full-size tractors can be driven manually as well as autonomously. He drives them to the field and then turns them loose after setting the electronic boundaries. Each generation gets better, with the goal of eliminating the need for a tractor cab.

It’s all a waste of money. I’m looking for tractors 2 generations back that I can modify to do what I want. Laird has a bachelor?

His next step was a Massey Ferguson using the same style computer interface and programming. In some ways, setting it up for autonomous use was easier than either previous tractor. Laird is still working on the transmission control.
