1618?

I hear all the talk about the 18 Kohler on these tractors being less than desirable. So, whats the gig with the bad rap on this motor?

it has over head valves. if not properly maintained they dont get the oil or something and blow up. (not literally)
Also the valves sit on to of the cooling fins which allows dirt to build up very quicky. If you don't keep the fins clean, the head heats up and warps.
Mine is running just fine. Aside from keeping the fins clean, what else can I do to avoid expensive sounds and pieces falling from the engine room?

Keeping the fins clean is the number one thing to do. I've heard of valves getting out of adjustment as well so I would check every once in a while. Some folks just have good luck with them and you may be one. I didn't have mine long enough to worry about it.

Hi,

I have never owned one (K361).

One issue that I have heard and seen evidence of is that the head is made from aluminum and the valve seat inserts are steel of some kind. So if the head is allowed to overheat (cooling fins not clear) then the valve seats come "loose" and then all kinds of bads things happen.

And obviously if you do not have an oil pump to provide oil to the rocker arms on top of the head then long term you will have issues with that area.
I'm not sure how to address the lack of lubrication to the rocker arms.

Good luck.

Yep, I knew there was something I forgot. The valve seats. Thanks Chuckbob.

I haven't had mine long enough to really run it, but I will pull the tin off and blow out those fins. Anyone know the specs for valve adjustment on these? The other post about the steel seats/aluminum head makes perfect sense. I had a Cadillac that had an aluminum block with steel cylinder sleeves. Besides just being a rolling turd, if you got it hot just one time it was a goner. The sleeves would drop down and whack the crank as it rotated. The sound was not pleasant at all.

I went and looked at this tractor today. The 18 hp runs like new and the tractor is real clean for an 81. However, it just didn't do much for me. The guy wants 2 grand or thereabouts. Maybe it was the smaller tires in the front? Don't know but I'm glad I passed.
What do you guys think the value is on this tractor? its an 81, the paint is in good shape with all the decals on it. Hydraulic lift and snow blade. It has the smaller tires in front, not the 12's. The K361 does run pretty nice. I know pics would help but I don't have any.
If it only has the snow plow and no mower deck, I think I would offer more in line of around $1200-$1500 at most. Some prices here in the New England area are sometimes superfiscially high for some reason and people try to get more than some items are worth and often times they get it. Hopefully you can low ball him and meet somewhere in the middle.

Wait a minute, this tractor has the k361 AND the 8" wheels? Something isn't right. I don't even think they offered the 8" wheels in 81. I don't have my books handy but I think they all had 12" front wheels by then. I definitely don't think they ever paired the k361 with a tractor that had 8" wheels. Of course, as usual, anything is possible.

i thought the same. i thought by then everything had a number for a model, and the only thing with 8 inch front tires were the 1612s. its possible that something is not original, or we will one again be confused by the mysteriousness of the company.

By the looks of this tractor all appears to be original. It is without a doubt a k361 in there. The biggest turn off for me was the little 8 inch front tires on it, I was very surprised to see them on there as well. I now see he has it on C/L for 2500.00.
I have dealt with this guy before, in fact I got my 62 Economy from him.
Its funny how he always says this one I'm gonna keep, its for my boys blah blah blah. SURE!

I'll be the one to go out on the limb here and say that something is not original. I don't have a brochure from 81 but I do have one from 82 and they didn't even offer a model with 8" wheels at that time. Did he put a picture in his ad? If so, post it so we can get a look at this beast.

Was that the 4100 series Caddy? They were JUNK!

Might be this one: http://newlondon.craigslist.org/grd/2775877898.html

Looks like it has short wide rims.I thought I seen somewhere where wide 8" extra wide rims were and option but I have not had time to check.

Yes it was, and yes it was.
i remember seeing something about the wide option also, i think it was for tractors that already had 8 inches on the front. if he says he doesn't want to sell it i think hes lying. he posted on the 28th asking 2500 and today asking 1800, big drop pretty quick. i see quite a few posts from bethel, looks like he wants sell every thing individually.

Yes that is the tractor. I'd probably make him some kinda offer or trade offer. Problem is he knows absolutely nothing about tractors and he'll want to trade back should a problem arise, or he constantly calls with any tiny little issue.
