Just had to reweld my brackets on my mid mount deck this last week
during change over. 15 min project turned into a 2 hour project. Metal
fatigue had torn 3 of the 4 sides. If I did not have a welder a
sandwich plate would have been my solution.

I was doing some cleaning up of my deck, and noticed some cracking
around where one of the arms connects to it. Now I understand
something I had been wondering about when I repainted it years ago -
where the other arm connects to the deck, there is a metal plate
attached on the underside. I'm guessing the previous owner put that
there to reinforce the attachment point, perhaps due to cracking. It
was either welded on or JB welded on, not sure (and the bolts holding
the arm on go through that plate).
I was thinking about doing pretty much the same thing to the other
side - get a sturdy piece of metal from our machine shop, drill some
holes in it, and run the bolts through it. I figured I'd also coat the
connection point with JB Weld, and thoroughly seal and reinforce the
crack above with JB Weld. Does that seem like it should work? It's
apparently been working fine on the other arm for many years (I've had
it for something like 7 years).
As a point of interest - this is what I believe to be one of the early
style decks, with the L railing on top of it in a triangle shape. I
think I recall reading something about these being more prone to cracking?
On a completely different note: I started trying to take apart one of
my wide deck motors. And this reminded me that if I were President, I
would ban the use of flat-head screws. I hate those things - they're
always stripping on me. I took the RTV goop "caps" out that covers the
screws on the bottom of the motor, so I could get to the screws
underneath (which I think hold the armature in from below?). They're
flat-heads, and not particularly deep ones. I tried turning one, and
it didn't want to budge easily, so I decided to try squirting a lot of
PB Blaster on them so I can hopefully get them out tomorrow without
stripping them.
Oh, and lastly - on the large deck motors, how is the top held on? Is
it the two phillips screws? Or the long bolts with nuts on them?
Thanks again,
Mike
