I forget the actual date of the move of production to Wisconsin, but at the oldest that is a mid-90's tractor due to it being manufactured in WI instead of NC.
Respectfully I don't think so. My late 1994 production tractor is model #987061, Shipped on 12/1/94, Sold to me 4/17/96, made in Brillion, does not have a Clemmons tag with an old style number.
His Ariens model number is 987004. His tractor has a Clemmons tag with the old number system showing model #050123. His group of tractors is in fact the last group shown on the parts radar with the old number system, and is also listed with the new number system.
This IPL, that I posted above:
https://www.gravelymanuals.com/pdf/Pro_G_IPL_0990.pdf
On the first page, clearly identifies his model number, 50123, and is clearly dated 09/90 as being the beginning point for that group of model numbers (50120 thru 50125 or Ariens 987001 thru 987006).
His tractor has the engine driven hydraulic lift, the group of tractors that my model number falls in has the original IPL dated 07/94 as the beginning point for that group of models (987058 thru 987063). That is the first group of tractors with the electric/hydraulic lift.
There are two other complete groups of Pro G tractors with 987XXX model numbers between his tractor and mine which would generally account for 1992, 1993 and part of 1994.
There are also "renumbered" Ariens numbers assigned to tractors older then his, the last of the 8000-G tractors.
There are also 987XXX numbers missing from the sequence that were never used.
But again, his model number is clearly identified as being introduced as of 09/90, with two other groups of G tractors between his and mine.
When did production move to Billion? I'm not sure. But the new model number system appeared with his group of tractors and was then clearly reverse applied to the last of the 8000-G tractors based on what is shown on the GRAVELY parts radar.
Was the move to Brillion during these overlapping model numbers? 1990-1991?
What we need is one of the guys with access to run the model and serial number thru the Ariens system........
