KT-21 Kohler in tractors/other applications?

Recommended Posts

powerking_one

Just some historical background questions here in the KT series of engines; it looks like Kohler pushed the envelope of these (most typical KT-17 & 19's) to to the KT-21. Does anyone know of these engines applications in tractors, welders, generators, etc? The complete gasket set PN looks to be the same across all 3 platforms. It would seem this variation was a "white elephant" and saw very few production numbers. To me, the KT-21 is like what the OHV K-361 was; a failure. The wrist pin diameter is different/larger in all 3 variations and with the rod journal being 1.500". So the KT-21 is a punched out bore to ~~3.325". Has anyone dropped in one of these say into a 7117? I'd imagine the power increase/performance would be quite noticeable. See the link below for more specifics:

I also do not believe any of the KT 21's ever made it to a becoming part of the Series II line, only the 17's and 19's.

id="quote">I tried to google that Brett and I couldn't find it either, I really thought they made a QT21, but after looking at my manuals, I saw they included the KT21 in the manual with the KT17 and KT 19, I think I confused KT with QT. i still don't know of ANY tractors with the KT21, wonder if any skid steers used them.

I found a few references to Ransomes using a KT21 but not any real info.

A bit about Ransomes being owned by Jacobsen at the time (Ransomes-Jacobsen), and some other references to Jacobsen-Cushman

So maybe you could look in those directions ???

As I read it, the manual covers KT17 and KT19 Series II and KT17, KT19, and KT21 original series. No KT21 series II.John U

id="quote">Yeah, I'm not sure about that, but that's the way it reads, but that means there were no KT19 series 11 engines, but how can that be. I was under the impression that the series 11 came out in 1980-1981, would that mean they didn't put series 11 engines in later 919s or that they didn't make the 919 after a certain date? The same can be said about the 917, obviously they put series 11 engines in the 917, so did they just stay with the series 1 for the 919 or did they stop production of the 919?

There were KT19 Series II engines. There were Not KT21 series II. John is correct, the service manual for the KT series will support his statement.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
