Tossing this out for discussion. I had not seen any of these before except for cars.
I'm pretty sure that I need one.
I believe I might want to make it a bit beefier since a number of my tractors are a little heavy like my Farmall Super M, the Super MTA, the 400-LP and the MF-165. I also believe that I would want heavier casters.
Since my shop floor slopes a little excessively (bad decision at the time of pouring) I would want very positive locking casters.
As you can see it is adjustable in length and you can also adjust the width of the rear axle supports. Just looks like a good idea. It also appears that it is easy to break-down for storage.
I'm on a lot of tractor sites and I am always amazed at how many tractors I see being worked on sitting on concrete blocks turned the wrong way (as if there is a right way :eek:).
