I also have a Jabalina 1 tractor. In decent shape but headed for restoration when i can get to it. 14hp Briggs, hydro and 3pt lift. I also have two D4-10 models with Wisconsin TRA10D engines & 4 spd trans, 2sp forward, with 2 speed rear end. The D4-10 has an automotive style clutch and rear pto shaft. Both these are in rough but drtiveable condition. Here's some pics. Jabalina first.
This is my 3rd D4-10. Picked up in St. Louis this summer...$50! Had it running the next day....driving too! 2 weeks ago at local show, it took honors of "Ugliest Garden Tractor"! I was actually proud....and not a Bush Hog insult as she is quite ugly at the time!
