I'm new to gardentractor talk, just today, and have owned JD garden tractors since 1977.

I just bought an already restored 318 last week, but the serial number decal had been sandblasted and painted over. I'm pretty sure it is at least a 1987, since it has the Onan P218G engine with Spec # I/10608D and Serial # F943184180.

Is there any way to find out for sure what year the 318 is. I want to buy the Operators guide and other manuals for it. :confuse:

The biggest difference in the 318's is the hydro linkages. You can match them to JDParts.com and narrow it down enough to get the correct manuals for it.

This post made me think back to when I bought my 318 & 400. All I asked about was how many hours it had, and how much it cost. Never dawned on me to ask what year it was....lol

Thanks for the jdparts.com suggestion. I wasn't able to use the hydro linkage to tell the year, but did find that the seat and springs assembly changed for 1988. Mine matched the pre-1988 picture, and with that and my engine starting in 1987, pretty much makes the tractor a 1987. So I have a range of serial numbers. I'm happy for now, cause that should let me get to the correct manuals. :smile1:

Welcome to the forum! JDParts is a good resource to keep in mind when looking for info. Engine serial no. is always useful as well. Now that you know it's birthday maybe you could post some pic's of your tractor.

based on the seat it sounds like you narrowed it down to 222001-475000 (83-87). You should be able to look at the hydro control (listed under power train). The first version is 222001-372595 (83-86) and the second version is 372596-485761 (86-88). The easiest to see difference is the control that you grab to move the hydro - on the early it has a big dog leg bent into it and on the second version it is straighter and is attached to a sheet metal bracket.

Hey, long time no post! I did a little more digging and looking at the tractor and now believe the seat was replaced from an earlier model tracter. Based on the "Transmission Control Linkage" and "Brake Pedals and Neutral Return" diagrams at JDparts and in the Technical Manual, i'm pretty sure my tractor is in the serial number ranges 485762 - 999000, or 010001 - 104040.

But I have another problem. The steering had a lot of play in it. The spindle bushings on the left end of the axle (power steering side) were badly worn, so I replaced them. I also tightened up the two cap screws on the axle to cut down on the front to back play, but it is still a little loose. There is some play in the power steering cylinder, between the back attachment to the frame and the front attachment to the Left spindle, but I'm not sure I can do much about that.

Does anyone have any suggestions?

Also on a related question, should the tie rod be curved. The parts diagram appears to show it is straight.

Any help would be appreciated.

Thanks for the engine serial # suggestion. The Serial # is F943184180. I found a place on the internet that deciphers the serial numbers for Onan engines, and it says the "94" near the start is the year it was made. Looks like I have a replacement engine.

Good Morning:

 

While trolling the Internet looking for stuff for someone else's post, I found info on another Garden Tractor forum about serial numbers. They said there that 318's with serial #'s above 600,305  started making you depress the brakes in order to start it. JDparts seems to verify that. Can anyone here verify that? Mine works like that, so I appear to have a lower limit on the serial number.

 

Also, does anyone know if there is any kind of crossmatch listing of tractor serial numbers to transmission serial numbers? As I said when I started this post, I don't have the Model/Serial No. decal. Also, the engine serial number appears to show I have a re-power.  But it is likely that the transmission serial number is original.

 

On a completely unrelated note, we just got over 10 inches of snow (other nearby towns got a lot more) so I thought I would post a couple of pictures.

Looking SE from the deck (50 to 60 foot high trees):

Lots of stuff shut down around the area.
