In two 4" plastic pipes screwed to a piece of plywood and fastented to the stone guard on the operators' platform. I got the idea from posts on TractorByNet.
I don't have need for chains all the time but when I need one, I just throw it in the floorboard of the cab up against the seat mounting. It is out of the way there and for sure wont fall off and get lost. I suppose that if I wanted to haul it all the time, I could place it behind the seat, but in doing that, I would likely eventually whack the cab glass back there and break it. Most of the time mine is stored by the door to my shop coiled up on the floor patiently waiting for me to need it for something. I have a 20 foot 5/16" and a 15 foot 3/8" that I use for tie-downs on my trailer and for dragging trees over and out. My BIL and I occasionally combine his 2 chains and mine to attach to a tree to pull it when cutting them down so they go the direction we want as most of them are hung up with each other and don't want to fall. He puts his on his bush hog and occasionally forgets that they are there. One time his chain fell into the deck hole for removing the blades and all of it ended up in the stump jumper and took some maneuvering to find the end and fish it all back out, that is after we finally found it in there. Amazing how that chain crawled in there like a snake.I like to have my chain with me at all times but haven't found a good place to put it on my tractor. How do you deal with this? Thanks.
