"D"- Man 827 #3 Posted July 3, 2013 No cool history here either but I think the model numbers have more to do with the rear wheel and tire sizes and the tire type: used turf or ag. Mark. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,040 #4 Posted July 3, 2013 Interested in knowing what the model and serial numbers are. Can see the ID plate below and up tight to the bottom of the dash housing in the 2nd picture. A bit of literature to get you started There is a lot more I should be able to dig up on a clear day.

fireman 1,021 #5 Posted July 3, 2013 Only real cool history I can tell you is the 1973 was the pre-cursur to the D series. That's why it's called the 18 automatic. Didn't really become the D160, D180 or D200 till 1974. They did offer an ARK550 loader and Brantley Backhoe for it! 1 Share this post Link to post Share on other sites

Hodge71 664 #7 Posted July 3, 2013 In the fall of 1971 Wheel Horse sales requested the R&D dept. to come up with a full size garden tractor with more power than the then big shot GT-14, a rear PTO to power implements and a category 0 3 point hitch. They ended up coming up with the 1973 18 auto which would eventually be the D180 in 1974. During their development they decided to go with a "divorced" hydro system with the pump being driven directly off the motor and the hydro motor being mounted to the transmission with a set of steel lines coupled to the pump to drive the unit. They called it the "in-line power train". They also had 2 hydraulic spool valves, 1 controlled the mid implement lift and 1 for the rear 3 point. There was a actually provisions to disconnect the rear rubber lines from the steel lines and use the spool valve to power rear mounted implements. Through the years there were improvements but the tractors were basically the same. In 1976 they improved the drive system by putting grade 8 bolts in the bull gear to help stop them from shearing off and damaging the transmission when they fell into it and also by putting an external brake band to aid the transmission's hydraulic braking with mechanical braking. 1974 brought the D-160 which was Onan Powered, and the D180 and 200 which were powered by Kohler 482 and 532 engines respectively. 1975 was the last year for D-180 and in 1976 the folks in South Bend entered into and arrangement with Guttbrod from Germany. They had them build a tractor for them which they rebranded the Wheel Horse D-250, it was based on the Guttbrod 2500 and was Renault powered. The D160, 200 and 250 all continued until 1981 when they discontinued the D-160 and continued on with the D-200 and 250. In 1982 both tractors disappeard form the line up of machines and the D was replaced by the C-195 or "Super C" for 1982 and 1984. In 1983 there were no actual C-195s built but there were a few 1982 leftovers sold as 1983's 5 Share this post Link to post Share on other sites
JackC 617 #8 Posted July 3, 2013 Very nice 18 Automatic. Speaking of loaders does anyone have any comparison information on the ARK versus the KWIK WAY? I believe the KWIK WAY has a smaller bucket. A loader, if you can find one, might run around $1,500. 1 Share this post Link to post Share on other sites
JamesBe1 82 #9 Posted July 4, 2013 Nice tractor. Welcome to the Dysfunctional D Family. 1 Share this post Link to post Share on other sites
brandonozz 168 #10 Posted July 5, 2013 Very nice looking tractor. Maybe some day my 200 will look that good but that is a ways off - function before fashion! Best part of the deal is the spare pump, transaxle and (hopefully) trans motor. D's are a lot of fun! 1 Share this post Link to post Share on other sites
