Shame on you Glenn /w3tcompact/icons/frown.gif I'm quite the opposite I guess. Being a dyed in the wool, board certified, card carrying, therapy seeking tool junkie I look at any task as an opportunity to add to my tool arsenal. Just ask my wife, but watch for that eye roll of hers /w3tcompact/icons/eyes.gif
Now if I were in your shoes I'd be looking at a 3/4 drive Ingersol Rand impact wrench for those blade bolts. That'll be handy to have with the tractor anyway. I don't have many 3/4 drive sockets so add a set of those. English and Metric. Shallow and deep. A few extensions, a breaker and a ratchet should round out that collection. Oh yeah, that'll probably need some dedicated storage and my tool chest is full so throw in a larger tool chest. Hmm, is my air compressor adequate for that wrench. Probably, but the shear size of that wrench compared to my little 3/8 drive will be an easy sell on the wife for a larger compressor. Now we're really on a roll. You mentioned a grinder. Of course, you'll want a sturdy pedestal grinder and a variety of stones and accessories. Can't beat a little die grinder for on the tractor touch ups. I also like a disc grinder when you need a bit more uumph. Better check storage space again, might be time to upgrade the tool chest again /w3tcompact/icons/smile.gif
