Friend Al,
You can just come up for a visit as I have two GT-14's....
You can come and compare for yourself....

But to answer some of your questions... It was built starting with the model year of 1969, then built until 1973. But almost no one has seen a 1973 model. (Perhaps 1973 was a very low production year.) This is the "heavyweight" of wheel horse tractors at the time.....other than maybe the 18 auto and later the D series). I believe it weighs in at 980lbs. dry weight. Add gas, oil, fluid and an attachment and you are well over 1000lbs. They are all hydraulic lift and hydrostatic drive. Most all attachments were unique to the GT-14's, but a snow plow from almost any later model year will work on them. And most 48" mower decks (70's era) can be made to work with some parts and fabricating. Otherwise there was a 48" mower deck, tiller and I believe a snowblower that were made specifically for the GT-14. One of mine is fitted with an Ark 500 loader.
Most came with 3pt. hitches, but both were swiped off of mine......

They of course have a 14hp kohler engine. Very unique gas tank up front.... And that about covers it unless someone else has something to add.
I don't have the C-125 you have.... But I have the C-195. I believe the GT would be about the same size as your C-125...but a lot heavier of course. My C-195 is the same size but about 4 inches taller if that comparison helps. I do believe the front end is built much heavier than the C-195. I also believe the axles are 1 1/8" dia. on the GT.
It is so far...my favorite tractor.
