Yow, and you a better wrench turner (better looking too) than this old gap-toothed hillbilly!  But, out in my field I ain't got'a nuff rocks to stack that tractor on whilst I crawl under to fetch a pump. 

Removing it from the top side is quite possible and certainly another option for those of us with bad saw horses.  A great mechanic like yourself working in a shop with the proper tractor stands and hoists, no doubt can beat the clock everytime, which I will always prefer when I'm paying the hourly shop rate.  I suppose it's nice to be young and limber too.  That, I ain't!
