    Default First time blade change Hardee Tiger T972 LT Bush Hog,Helpful Tips

    Want to change the blades for sharper ones I have. Looks like 1 7/8" nuts in the access hole. Any tips? I just ordered the socket from Grainger and have a 3/4" breaker bar. Should I change the bolts also???

    Welcome from Va. The bolts should be good for years. Put some penetrating oil on them a few days ahead of time and let it soak in.

    Great tip Ed. Will do that. That should make busting those large nuts a little easier. Thanks for your help!! JM

    I've heard PB Blaster is good stuff, will take your advice and get some. Years ago when I had a repair shop we would use Liquid Wrench, may still exist,as some use WD -40. Not sure that's as good. Thanks for the tip !! JM

    Somewhere on TBN is a rating system for penetrating oil. Liquid Wrench was good, Kroil was better, Ed's Red (equal parts acetone, mineral spirits or kerosene, and Dextron III ATF) was the best.

    WD 40 and PB Blaster were not as good as these three for breaking rusted nuts from the bolts.

    Ah, found the thread:

    If all else fails don't hesitate to heat the nut to dull red and it will come right apart.

    Thanks for enlightening us all...sounds like fingernail polish remover and mineral spirits, but I've got some atf (dexron 111) around too. Maybe I'll put a little of all of these on for a couple of days before I crank on these nuts. Acetone will evaporate quickly though, especially in the heat here in SC. Just waiting for my big socket to arrive from Grainger.
