I HATE DECK CLEANING !!!!

[Mower manic]

I speculate that most of your problem lies in your grass. I am arriving at this assessment because my grass does not stick to the under side of the deck, (we have very different types of grass). I know from reading your past posts that you do not cut wet grass and your grass is quite fine, at least compared to southern grasses...So I'm of the assumption that because your grass is so fine, it clings to the under side of the mower. The moisture that resides in the grass itself facilitates this adhesion...so it accumulates.
I suspect the way to deal with this problem is to use the pressure washer more often and avoid the scraping part of your cleaning. Try pressure washing every 10-15 hours and perhaps you won't have to scrape at all. I would also suggest fabricating a low pressure, 180* (or less degree angle) device to wash build up before it gets a chance to dry and harden, using the pressure available from your well or public/municipal connection
Such is the cards you are dealt my friend. You can deal with it more often with less work, or 2-3 times a year with more work.
As far as coating your deck goes; I don't think any oil will get you to where you want to be. Nothing short of a very expensive teflon coating will create the surface you are looking for. If you could get it very clean and there is paint on the under side yo may want to try a silicone product, but only if you still have a comprehensive painted surface.

The manual for my 1000 series Cub Cadet says never to use water to wash the deck since water could get into the spindle bearings. Now that I have greasable Oregon spindles installed, I wash it.

The only noticeable difference between the stuff that comes out from underneath my riding mower decks and horse poop is I don't THINK that the deck grass spent any time in a horse. That being said, I've been somewhat satisfied with that non-stick spray cooking coating, but even then, it's a chore.:frown:

Get a deck wash if you can it makes the job 5 times faster:biggrin:

My new mower has a wash port and it works well but you need to use it regularly not let it build up.
It sure beats laying under it with a hose.

Two ideas, one is a replaceable poly-plastic liner, similar to those used by painters in their pails of paint.
The second is a plastic deck (Honda uses one).
No matter, the grass will stick anyway.
The third, and best, is to have a goat "mow" the lawn, better yet, a horse and have in essence, no lawn.
Work is something that a man cannot escape.
The deck manufacturers can give some engineering thought to this.
Maybe HF will introduce to the buying public a cheap deck scraper (rounded edges).
With my "lawn", I must stop and scrape every 5 minutes, as another alluded, the scrapings look to be one step short of horse manure !

Just thought I'd mention that in passing...:ashamed::laughing:

I'll bet that the manufacturers don't want to spend the money on a really long lasting deck because there aren't enough people that would pay for a mower that would last "a lifetime". An aluminum deck with a Teflon coating comes to mind, but it would be susceptible to mechanical damage, like when your mother in law cuts a bratwurst in half on your Teflon coated Calphalon pan..:frown:

Hey JDGreen, have you thought of buying a mower jack?

 

[JDgreen]

That WOULD be a huge asset to cleaning the deck but I dont think they market them yet for a 3100 pound CUT.

If you don't want grass to stick, get a paint brush and some motor oil, and put a coat of it on the underside. That will stop most grass sticking

This is a bit of a silly idea but thought I would float it out there. How about adding fuel injectors to the underside of the mower deck that spray cooking oil (or something lawn/yard safe) to prevent grass from sticking. Using this system one could perhaps even cut wet grass?
