Could thoughts on the 318 off the top of my head...


- Two different Onan engines used in them... The B and the P series.  Both have their quirks.  If cared for 2,000 hours are possible out of either of them

- Carbs and intake manifolds can be problem areas.  The intake leaks where it joins the block

- Hydros are solid and last 

- Open frame design shared with the 316(onan)/322/330/332

- Like other Deere tractors, there were revisions along the way so serial number is necessary to figure of changes and fixes



I am sure there are others that I am forgetting

My only concern is this ...when I was in my early 20s my father bought a 318 worked great for a few years then started blowing the oil filter off ,regularly like every 5 minutes or so. That was way before I started tinkering on garden tractors etc...

I think, it's a good decision to enlarge the herd w/ a 318...

Hydro guy:


I bought my 318 in the fall of 2011, and I love it. Only had a couple of problems, wouldn't start which turned out to  be cleaning the battery cables and posts, and having to replace the main spindle on the 50" deck. It had been restored before I bought it, so it was it really good shape.


I would recommend it. Let us know if you buy it. I have some documentation on it that might be of use to you.


I see you are in Iowa. I grew up on a small farm in central Iowa, moving to Minnesota in 1968.

My parents bought a new 318 in 1987 and that tractor is still faithfully mowing their yard every week in the summer along with having plowed their driveway many years through the 90's and into the early 2000's.  Their yard is 95% on a fairly steep hill and the tractor ran it's 50 inch deck and a rear mounted grass collection system that ran off the rear pto of the tractor for many years as well.  About 4 years ago dad decided that the Onan in it was starting to use to much oil and also rattle and he opted to replace it with a new 23hp Briggs Vanguard re-power kit.  Other than this change and having to put in a new ignition control box a couple years after they bought it (due to being washed with a pressure washer and getting water in the box) the tractor has been completely trouble free.  


I know they are not cheap to rebuild but I personally think that he should have rebuilt the Onan and kept running it.  The Onan just had it's own sound and I loved running that thing with it in there, the Vanguard on the other hand has no personality to me and I don't care for the sound.  It works ok but it isn't the same to me.
