BX-2200 Grass Catcher

Just noticed this post.

I have similar problems with my bagger of the same vintage. All other pins/bolts got chewed up regularly. I've made the change to rolled pins and have had much better success. Things are a pain in the spring (winter sticks and twigs in fan) and fall (too heavy leaves and/or sticks and twigs), but only pop one or two during the course of a "regular" summer. In spring/fall, I've popped two pins in a single mow. I have LOTS of trees, though.

I'll certainly check the oil in the two gear boxes in the bagger unit. Haven't thought about it. I now have a trailer sufficient to carry the bagger, so perhaps I'll send it in along with my tractor at my 200 hour service.

I engage my PTO at idle, especially with MMM and Bagger installed. Never get anything beyond a puff of smoke. I then throttle up to just off WOT. Makes a big difference in how much noise eminates from the deck and it still cuts great.

We have sold a bunch of them with only a few complaints on the shear bolts. Make sure you don't overtighten the bolts, Engage at an idle and then rev up and make sure you are using Kubota shear bolts. It is designed for Grass and Leaves, So pick up the branches.

Ok, so the change of gear oil did not fix the problem, broke (3) more shear pins!!! After looking at the issue a lot close with my dealer, we are sure that the lock washer has no spring left in it, causing the nut to loosen up, giving the bolt just enough play to be "sheared" by the axle onto the shaft. I replaced the split washer and lock-tite'd a new nut. I have not busted a shear pin since...that was three lawn cuts ago...hopefully this has fixed the problem.

That sounds like the right answer. Any pin will shear much more readily if there is play in it. Before I saw the last post I was thinking that the bolts might be just a bit small in diameter. At any RPM there is quite a snap when the PTO engages!
