Has anyone ever come across anything or any way to keep the
underside of a mowing deck (tractor in this case but same with my
pushmower) clean of debris? I have lawn tractors that are 32,
24, and 3 years old respectively and only one is no longer
functional - it barfed its guts all over my driveway one day when
I was using the sweeper. The other two are in the Fair and Very
Good categories respectively. But both have corrosion under the
deck, which is always the first thing to go on a lawn tractor it
I do admit to having heavy use; about 1 1/2 acres weekly this
summer at least, and 4 acres three times a season to keep it from
going to brush, but it was 4 times this year.
It's not too hard to wash off the top of the deck, but the
underside is never easy to get at and the grass likes to stick to
it, no matter what Iv'e used to coat it with (paint wise).
Without lifting it way up so it's completely visible and
accessible, you just cannot completely remove the grass from it
which results in a clump/s growing and eating the metal.
Please don't advise about only mowing late afternoon, low
humidity, etc.; I know those things. I'm only interested in a
finish/covering/method that will prevent grass collection damage
under the deck. The best I've found so far is alk enamel, gloss,
and mulching blades for the extra air movement, but it's far from
a long term fix at best. Yes, I resharpen the blades three
times a season.
I was reading some manuals at Sears the other day: Would you
believe there are actually recommendations now to use ONLY
compressed air for cleaning, because a hose might cause damage?
They didn't say what to, but there was a vague mention of the
electronic ignition. I don't think we'll see any improvements in
the decks real soon. Most of the mfg's seem to think "12 Ga" is
a special, extra thick metal; or so they'd like is to believe.
Even John Deere, one of the best out there, has the same problem.
