First off, for a little background, I have a 1276 and a 72' GT-14 which I inheireted from my Grandpa who bought them new. Used both for a while until the hydrostat gave up on the GT and shortly thereafter, the motor on the 1276. Swapped the motor to have a good running tractor which left me with a "stripped GT-14" and somehow in the mixup, a turbo on the 1276 (which I will get into later).



Anyway, I started out by buying two bad 8 speeds with intent to make one good one and swap out the old wore out hydrostat unit and then power it with a v-twin or really just anything bigger than the Kohler that it originally started with. Ran across a good deal on a Yanmar 3-cyl diesel but now I have a dilemma on my hands..


What can I use for a shaft driven transmission? I think the 8 speed idea is getting scrapped in favor of some sort of shaft driven setup (preferably with a rear pto aswell). Has anyone done this? The only thing I can find are Cub Cadet transmissions, in which I really can't "find" to purchase one. Is that like totally against the rules in the Wheel Horse world? Haha.

You might get a lil ribbing for putting a CC tranny in there, but it's your tractor. You could also put a right angle gear box on the Yanmar & still use the 8 speed. Either direction is going to involve some heavy fab work. Of course we would want pics of the build, no matter which route you choose.

A right angle box was the first thing that came to my mind but they are super expensive and kind of weak. I found a source for a 12 puck pulling clutch that I really don't need, and that will allow me to run bigger injectors.. And I also just picked up 2 tiny turbos off a Volvo at the junkyard today.. See why this is called the snowball project?



I'll have to get some pics of the GT-14, I'm sure it will be totally out of hand by the time it runs so  stay tuned. 


I do have a pic of the turbo 1276 in which I just took a junkyard turbo that was way too big and bolted a carb on the front and it just kind of worked. That's the one I cut grass with weekly

Does the turbo actually work, or does the carb just pass through it?

      Another GT-14 in the Herd.
      Not perfect, but it runs & drives.
      Doesn’t smoke.
      New carb & fuel pump. New tires.
      I have a super nice seat for it.
      We’ll see what becomes of this one.

      Pair of Goodyear Sure Grip Lug tires, size 27x8.50-15. New, never been mounted. Bought these for my GT-14 project and then found something I liked better before I got to that part of the project.  Also stock size for MTD 990 and it's variants.  Can ship if buyer pays shipping.

      I actually work at a lawn and garden dealership. A friend of mine is trying to restore his GT-14 and he needs a clutch. Toro's IPL are incomplete but I managed to find the pdf for the parts list elsewhere. I came up with a number of 9656 for the electric clutch which subbed to a 101473; both of which are discontinued. So here is my question... Does someone out there have the manufacturers number for that clutch. I have access to about 30 different manufacturers so i could probably find a clutch that would work but most of them don't publish shaft sizes in an intelligible format. With the manufacturer's number I could probably easily substitute it.
      Any help is greatly appreciated - this sight has helped me in the past, personally and professionally so I know if anybody can help it will be you guys.

      I'm working on my GT-14 and the choke and throttle linkages are disconnected. Can someone please post some of how they are supposed to be hooked up?
