A get off the tractor button. I would love a switch that would secure the tractor with one button. How many times have you wanted to hop off, but you have to step on the brakes, lock the parking brake, put the tractor in neutral, throttle down, get off grab the one thing and then reverse the whole process.
I have been doing a lot of underbrush clearing lately and I have a lot of wild grape vines growing in the woods. These are not the edible type of grapes but instead just long 1 to 2 inch thick vines that can be 100 feet long and need to be cut up because otherwise then tangle up and just pull everything out of the bucket as you try to back up.
I would love this for my zero turn mower too so I could quickly hop off, grab that one piece of trash and get back on.
