摘要：
A method of guiding farm equipment is provided. The method includes the steps of attaching a trench forming device to a tractor in front of the rear wheels of the tractor, traversing ground with the tractor equipped with the trench forming device set to a desired depth, forming a trench for guiding farm equipment in front of the rear wheels of the tractor as the tractor traverses the ground, engaging guide wheels attached to the farm equipment in the trench, and guiding the farm equipment by tracking a path provided by the trench. A trench forming device is also provided. The trench forming device includes a trench forming mechanism for forming a trench in ground traversed by a tractor equipped with the trench forming device. The trench forming device is attached to the undercarriage of the tractor and located behind the front wheels and in front of the rear wheels of the tractor such that a trench can be formed in front of the rear wheels when the tractor traverses the ground and the trench forming device is set to a desired depth and engaged in the ground.
