318 Deck Height

I picked up an '83 318 last fall which included the original 48" mower deck. I used the mower a couple times last fall and wasn't impressed compared to my old 112 with 47" deck. I didn't mess with it last year. I did my first mowing of the season last week and the day afterwards it didn't even look like I mowed.

Looking at it, it looks like the front is sitting way too low compared to the back but that's not what taking measurements off the blades say.
Today I went out and check the deck level. One thing I noticed is that with the wheels set at 2" (2nd hole from the bottom) if I set the deck level to put them 1/4-3/8" off the ground the height from the ground to the mower blades is over 3 1/2". I put the wheels all the way up and set the stop to leave them off the ground the required amount which should be 1 1/2" and it gives me a cutting height of 3" still. Quite a difference. I also measured the difference from front to back and I have the required 1/2" on the blades but the rear wheels are a good 1 1/2" off the ground while the front ones are 3/8". I just mowed again, not that you can tell from all the long grass still sticking up. Other than looking for a new model 48" or 50" deck I don't suppose there's anything else to do with mine but live with the lousy cutting.

Looking at it, it appears the front of the deck is way too low, but as I mentioned the measurements off the blades say different.

The wheels do not set the deck height they are there to prevent scalping. The height of the deck from the ground is controlled by the height adjustment screw on the back of the tractor.

There is really no easy way to get everything level, just takes patience. You have adjustments on both draft arms and you have the adjuster on the hanger strap on the left side of the tractor (sitting on it).


I have the 48" Replacement Deck on my 318 and the sticker regarding what hole to set the wheels at for a specific height does not agree with where they end up after I adjust deck.

Simply all I do is set the deck height where I want it and then adjust the wheel height to 3/8" to 1/2" off the ground.
