36" side discharge mower issues

[rondo 0]

Haven't used the Horse to cut yet this year - until tonight. Set it up and have two issues. One is minor and I'll fix it - go into that in another thread.

Bigger issue is the deck. It misses lines as it cuts - like one or more of the blades (3 total) isn't turning, or at least not turning well enough to cut. I think it may have started to do it late last year, but it's not consistent. In fact, when I started out tonight it was cutting fine, then I could hear it change tone a little and suddenly it was leaving uncut patches about 2-3 inches wide. Hard to tell exactly where it's missing, it's not always exact - almost like something is slipping or mis-timed (if that's even possible). A little frustrated, but hopefully someone has dealt with this before.

By the way it's a B-100.

Thanks guys.

I had my 36" deck do that once, but could probably happen to any size deck. Do you remember hitting anything hard underneath the deck or with the deck at anypoint? Turns out I must have hit something or somehow bent one the spindles out of alignment so the deck belt didn't run a constant tension on all three blades at all times. It was especially noticeable when I was mowing either tall of thick grass. I replaced the spindle and haven't had any trouble with that deck in the two years I used it after the fix, of course I haven't used it this year either... Got a bigger horse with a wider deck

Just my thoughts

I've had this happen before on other decks and found out I had dulled just one end of one of the blades by hitting something. For whatever reason the "skipping" was random, but as soon as I resharpened everything the problem disappeared. Just a thought.....
