55 gal barrel on the roll around wheel thingy and a hand crank is easy and pretty cheap. Just don't trust the tractor fuel gauge...'cuss it's really slow catching up with the tank volume...mine says 3/4 tank when it starts running out on the concrete...learned that the second time.
By the way, I haul 2 barrels to the off road diesel store in a trailer and welded about 4' of 1/4" chain on each side of top ring of the barrel (before filling them the first time) and this works great to pick up barrels, full or empty with the bucket or backhoe.
BTW...cabs are great and so is the heat and A/C...can't believe I suffered for so long out in the weather...yeah...I'm getting old and soft.
