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.

I wonder if you have the draft plate for a 41 deck instead of a 48. there are pictures of the two somewhere on this site.

if you do have the wrong ones, I have plenty of them for 48" decks, and will swap one with you if you want.

Personally I like a tall cut height, but thats a separate discussion

you can change the draft plates on a mule drive, there is only one bolt that holds them in. your comment also looks like this has never worked right for you, which also makes me suspect.

can you take a tape measure and check how long the straight part is where the draft plate mounts to the mower itself.


One other question, approximately how high are the blades compared to the bottom of the deck skirt? I don't have a 48 to check, but maybe the po did a mix and match rebuild? Just a thought.
