Is formula to figure out what year my 80 dump cart is made? The number is on a foil sticker, # 8417. The "chassis" is black, a late model. It doesn't have rust, just some minor surface rust. I'm guessing it's 1984-1988. How do you figure this our? Appreciate to figure it out.

I'd like to haul the grandkids around in the 80 with my 1976 68 rider. :-]

Welcome to GreenTractorTalk. You have a real treasure with an 80 Dump Cart. They seem to last forever. I have never seen a serial number breakdown on them, but mine is somewhere around 30 years old and has a stamped, riveted on metal plate. I don't remember when JD went to the stick on serial number plates, but someone may come in on this post with better information.

elarsen - Your very question has been asked on many John Deere Lawn and Garden Tractor forums across the Internet. To tell you the truth, and others will agree, there is really no conclusive direct answer for that question. The only answer anyone has come close to getting is what John Deere themselves are able to produce. Apparently John Deere didn't take as much care documenting SN for items such as Dump Carts as they did with their tractors when they began manufacturing such items. I don't think they believed items such as the 80 Dump Cart would eventually become a collectors item.

Below is a model number mapping of the date range for the 80 carts that comes directly from John Deere. Only the 1968 carts can be narrowed down to a single year model, as they have brass tags AND an E0900 model designation on their tags.

Carts with foil tags do not have a serial number but rather a "date code" which is most likely in the form of YYWW where the first two numerals are the year and the last pair are the week within that year(1 through 52) but this has never been confirmed as the official meaning, to my knowledge. I hope this helps somewhat.

Kenneth-
Thank you for the info!
Funny, that was one of my guesses, (yr/wk).

80 dump cart Value (1968-1969)

It looks like I have a 1968-69 80 dump cart. It is a little rusted but pretty still in good working condition. Could any one tell me what the estimated value of the cart would be?

I love my 80 dump cart. I've had that thing piled high with limestone rock and she was rock solid (pun intended)

Looks like I need to take a look at the serial number on mine as it appears it may be earlier than I thought it was (it's a white one - wish it were green)

 

[javjacob]

I know on the foil tag the first 2 numbers are the year and the last 2 are the week. So 8417 would have been made the 17th week of 1984.

 

[javjacob]

Also on the foil tags its a date of MFG which it says on the sticker, its not a serial number. many foil tag carts can have the exact same "date of mfg" numbers because they made more than one a week.

Jbanit,

MN is a pretty good market for 80 carts. I've sold several like yours in the $2-300 range. YMMV

Sorry I meant Jan 17

The date code on the foil tags narrow the production down to a week span of time and cannot resolve to specific day. Further, the date code in question here falls in late April as seen here:

I just brought home a nice 80 cart. Date code 8432. (April 1984)
Bought from the original owner. All original, with very little surface rust.
The tires still hold air.

 

[Chuckv]

Boonie,

Nice score! These are very robust carts. Glad to hear it got such good care from the original owner.

Your cart date code is not for April but for August of 1984. Here is the detail of the beginning and end dates of that week:

Week 32

August 6, 1984

August 12, 1984

Week 17 could be one of four dates depending on how a company pegs it's fiscal year. For example, if a company starts it's fiscal year in July (not uncommon), week 17 would be in October. I appreciate that this observation doesn't advance the discussion about trailer genealogy (which I'm here for, too), but I felt compelled to make the point.

And having just checked JD's corporate calendar, it appears their fiscal year starts in October, week 17 occurred in January.

I believe that the date codes that use year and week are all calendar year -- at least that is how electronic components are standardized as to manufacturing dates...

I also do not understand how "fiscal year" would limit the choices to just four dates...companies are allowed to have an arbitrary accounting year. It can be either 52 or 53 weeks in length for tax purposes:

• A fiscal year consisting of 12 consecutive months ending on the last day of any month except December --or--
• A fiscal year that varies from 52 to 53 weeks but does not have to end on the last day of a month

The ISO has a bit more formal definition:
An ISO week-numbering year (also called ISO year informally) has 52 or 53 full weeks. That is 364 or 371 days instead of the usual 365 or 366 days. The extra week is sometimes referred to as a leap week, although ISO 8601 does not use this term.

Weeks start with Monday and end on Sunday. Each week's year is the Gregorian year in which the Thursday falls. The first week of the year, hence, always contains 4 January. ISO week year numbering therefore usually deviates by 1 from the Gregorian for some days close to 1 January.

There are many on-line week number calculators based on the Gregorian Week definition and that is the one Deere almost certainly used....
The weeks of the year in a Gregorian calendar are numbered from week 1 to week 52 or 53, depending on several varying factors. Most years have 52 weeks, but if the year starts on a Thursday or is a leap year that starts on a Wednesday, that particular year will have 53 numbered weeks.
