garylewa 4 #1 Posted January 13, 2018 Gentlemen, Attached the snow-thrower to the B80 with no issue, when I lift the unit it usually locks in the raised position; I hear a click also for verification. This snow season the thrower never locks in the raised position causing me to continually keep the lift handle pulled towards the driver. Does anybody know where the "lock mechanism" is that does this? Thanks (again....), Gary Share this post Link to post Share on other sites
Racinbob 11,044 #2 Posted January 13, 2018 Since it sounds like it did work per chance did you install the 'flag' in the wrong hole in the rock shaft? That could cause the lift to try to raise the blower past it limitations and hit something before it latches in the raised position. This is what locks it. Pirated from the net. I don't know what they were measuring. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,032 #3 Posted January 13, 2018 This is from a later model and lift arrangement but the lift arms are the same and have the attachments lifted by the same holes in the arms. Garry 1 Share this post Link to post Share on other sites
Jerry77 1,218 #4 Posted January 14, 2018 The lift arm may just need some lubrication - try squirting some lube down the shaft...I have had them fail to work from just being dry.. 4 Share this post Link to post Share on other sites

Make sure your flag is in the top hole of the rock shaft (item #19) as shown in Garry's illustration in Post #3. Also, there are usually shims on the shaft between the flag and the lift rod. If there are to many shims, it will cause the lift rod to hit something up front before the lift handle can come back far enough to engage the lock mechanism. Hope this helps. 1 Share this post Link to post Share on other sites
Jakeshorsetuff 36 #7 Posted January 15, 2018 (edited) There should be a little piece of metal were the lift lever locks. I had this problem with my tractor when I lifted something heavy so what I did is put a stiffer spring in the lift lever and it works great now.

jeff lary 171 #8 Posted January 16, 2018 (edited) I always learn something when I read the forum. Mine is a 95 and I have never thought to lube the lift shaft spring mentioned by Jerry in post #4. Thanks Edited January 16, 2018 by jeff lary 1 Share this post Link to post Share on other sites
