I know this is an old thread but I have a LA435 loader for my B2301 with the dreaded quick connect which I absolutely hate. After about 300 hours and just out of warranty it no longer connects tightly so it leaks pretty bad. Now there is about a 1/4 inch gap when I attempt to lock it down and simply won't lock anymore. Can't figure out why but I am ready to convert to all single couplers.
I have single couplers on my snowblower and it connects fine and doesn't leak so I know the problem is that dreaded connector on the loader.
Anyone else having these problems and what was your solution
