jsp_333 268 #1 Posted October 31 So the other day I ran over a 1/16" steel bar with the mower deck. The blade the bar was wrapped around was spinning freely. Is there a sheer pin (like on snowblower auguers) that I should be looking to fix. I'm hoping anyway. Or is the whole spindle shot. I've put a washer on the spindle to tighten down the blade for the last mow of the season but want to fix it properly over the winter. Any help appreciated. cheers jsp.

ri702bill 8,421 #2 Posted October 31 (edited) First off - Ouch! Got a picture of the deck so we can Identify it?? No shear pins on these. The later decks have blades with a round center hole - it is a "squeeze fit" to drive it. Earlier ones had a "Double D" hole that did give a positive drive from the spindle shaft - both used 3 blades that are not timed. The very early gear drive decks had 2 blades that were timed to miss each other. BAD things happen when an impact disrupts the timing....

jsp_333 268 #3 Posted November 4 42 inch rear discharge deck with round centre hole for the blades. Sorry deck is back on the tractor. I guess it lost the squeeze as the blade was just spinning freely when I took the deck off. Put it all back together with no apparent damage - touch wood. Just curious as to how it lost the squeeze.
