An alternative to GNSS satellite-based guidance for tractors working in row crops has been developed from a precision hoeing system to further increase accuracy and reduce operator fatigue when carrying out row-crop operations.
The Robo-pilot from British manufacturer Garford Farm Machinery links the high definition Gigabit Ethernet camera and image analysis software used with the company’s Robocrop weeding hoes to a tractor’s steering system.
Mounted on the front of the tractor, the camera views the crop ahead and image analysis identifies the centre of the crop row foliage; it can also guide a rear-mounted Robocrop hoe at the same time, all with a claimed accuracy of just 8 mm (0.3 in).
This combination provides the high-level accuracy needed for auto tractor guidance in row crops to make hoeing and similar operations less tiring for the operator and to allow work to continue at night or in daytime conditions of very poor visibility.
Components for the Robo-pilot system, which starts at UK prices from £13,500, include the camera and mounting bracket, a steering angle sensor, and a GPS speed sensor, plus a new control valve with auto cut out flow sensor to operate the tractor’s hydrostatic steering, or a steering wheel actuator.
In the cab, Garford’s Robocrop 4-quick touch! console gives the operator a view of the crop ahead, with icons used on the touch-screen display for setting up and adjusting the system.
The console has capacity for up to 6 cameras in total, so wide working implements such as the trailed Eliminator precision hoe and triple bed InRow active hoe – which takes out weeds between precision-sown plants as well as between the rows – can be guided along with the tractor.
