i have a project in mind involving my tractor and my farming operation. what i want to do is use gps to steer the tractor for me (that i will be riding in at all times!) so i can focus on other tasks while doing tillage and planting. it will only have to drive in a straight line i will make the turns and line up for the next pass. my thoughts were have a pixhawk and piksi along with a stepper motor assm to manually turn the steering wheel. two methods i was thinking of were trimble ez steer or agleader. we have used a light bar guidance on our farm before but this year going to conservation tillage and need to drive over the previously placed fertilizer strip with the planter within 4" or better. with our small farm we can not justify the large expense of RTK.
what is everyone response or concerns to this idea? i appreciate any input or suggestion i can overlook some important details at times
