Shuboxlover 474 #1 Posted March 15, 2011 I am starting to think about spring, but i can't get the nuts loose so I can sharpen the blades on my 60" deck on my 520....does anyone have any tricks they have used to get the nuts loose? please let me know... i have soaked them in penetrating oil to no avail.... :thumbs: Share this post Link to post Share on other sites
sorekiwi 761 #2 Posted March 15, 2011 I use a $15 Harbor Fright 1/2" drive rattle gun, with a piece of 2x4 standing on end under the blade to stop it turning (mower deck standing up on its rear wheels). Share this post Link to post Share on other sites

Kelly 1,028 #4 Posted March 15, 2011 Impact wrench they come right off, take it with the socket to a shop near you, I'm sure they will zip them off. Share this post Link to post Share on other sites

tarcoleo 119 #6 Posted March 15, 2011 Impact wrench at friendly auto repair shop worked for me last year. Put nuts back with an easy-off on threads to prevent problem next year. Tom in RI Share this post Link to post Share on other sites
tarcoleo 119 #7 Posted April 8, 2011 The problem for me arose again with a 48" SD unit purchased recently. This time instead of going to the friendly neighborhood auto repair shop to use his impact wrench, I was able to free the difficult nuts using a robust 1-1/8 open-end wrench. The technique simulates what an impact wrench does; the impact wrench delivers many impacts to the nut before it is finally loosened. The regular wrench (with a wooden block on the blade) was hammer-struck many times until the nut loosened. It just takes a little more time than with the rattle wrench.
