My front line tractor (don't fucking laugh, it's the best one my dad left me) would barely pull itself out of the shed the other day. Of course haying season is upon me, and I really need that machine, but it needs a clutch unbeknownst to me until now). So I brought it to my shitty little shop that at least has a concrete floor. It's not flat or level, but it's barely better than dirt and offers some shade.
Well my idea of using an engine hoist on the front half was not gonna work.
So, I had a bottle jack, some scrap 2" square tubing, and these aluminum wheels with bonded rubber tires ( that came from a ski tuning machine I scrapped years ago).
I farmer welded it all together and got it in place, with an old hydraulic jack from a Harbor Freight pipe kinker to hold up the back end.
I have to say, it worked surprisingly well. I can only imagine how well it would work on a good floor.
