Well I decided to get my Hydro running yesterday so at about 10:30 a.m. I started to work on it. I knew it needed the coil and magneto because the guy I bought it from was going to part it out and already sold those off it. Luckily I had an extra one of each, so I put those in and tried to put the S/G belt on but it didnt line up with the flywheel pulley. They had the top bolt of the S/G bolted right to the gas tank tray and and the S/G bracket was missing. I didnt have an extra so I had to make one. Once I had the bracket bolted on I loosened the mount on the engine mount for the S/G to slide it out more but wouldnt budge, turns out it was the two bracket for the S/G were welded in the wrong spot, so I had to take the battery tray off nad take the S/G out to unweld the brackets, after those set backs put new fuel line on, and bolted everything back together and it cranked over. So I borrowed a carb from a running tractor and it fired up and sounded good, a little carb tuning and it ran like a top. :woohoo1::bannana::bananapow I took it for a ride after that but it was about dark and it was suppost to snow tomorrow so I put the plow on it. Finished putting it all back together at 7:00 p.m.


Today I put the stack off my '69 Sub 12 on it and a set of wheel weights on it and plowed for a while with it, they are fun to drive, but after only driving geared ones before it took some getting used to. I switched hoods and put the hood vents off a Super 12 on it. Enough talk, heres some pics.



You can see the horn button I got from the end of a cinnamon roll tube, fits perfectly. Still got to find some seat springs that fit like the originals.


Here is the S/G bracket I made with the "S" hook on it.

Out of all of them I bought I think this one gave me the most trouble to get going, but it was worth it, its fun to drive, runs good and the trans work good.

Last weekend my dad, brother, and I were looking at some ford parts at a guys house and I seen a chrome muffler off an old motorcycle laying in the corner of his shed so I picked it up and he said if you want it its yours. Awesome. Chrome is nice and pipe dia. is 1.5" perfect for a new stack. Sounds great at full throttle and can hardly hear it at idle. It will be going on my '69 SS 12 this spring. Also in this pic are my new used 8.5x12 ags.

Let me know what you think.

Awesome! How does she push the snow?
I was surprised how well it did with no chains, but I may add them later. The rear ends of the hydros must be quite a bit heavier than the geared trans.

Hats off to you and your Sears GT's! Very good tractors you have there, I do miss my '69 Sub! Nice work with the s/g too! :thanku:
Yep, just like that. lol Yours looks good.
Are these what your seat brackets look like? Is the short end the top?

Thanks, I've been pretty lucky getting ones that arent too hard to get running and run good.

SS12, Those are exactly what you need. Those are original seat springs. And for $14, I would grab them myself for spares. - Brad

Thanks, I will have to get them. So there is only a narrow piece that connects them at the top that the seat sits on?

Yes, Here are some pics of mine. You can see the little flat stock cross over peice. If you can't find one on ebay, A peice of flat stock will work fine. The only thing I don't like about this set up is that the seat isn't adjustible (very much). I'm 6' 5'', So i need a lot of leg room, And the hydro tracs seat differantly than the geared tractors. If you can't find that peice, Let me know I will get you the measurements. - Brad

Here are some detail shots of mine. I was incorrect about the nubs to prevent the seat from rotating - it is accomplished by tabs on the bottom of the seat itself.

These are pictures of my '69 - the '68 has a padded seat and might not show the details as well. That, and it is covered up for the winter.

From the back, showing the anti-rotation tab:



From the side:



From below. Looks like there are three positions for the seat and mine is all the way back. I have short legs so maybe I'll try moving it up a notch:

If you need other shots, let me know.

tractrjoe-
Thanks, I am rounding up some parts I need for it, but I kinda like the patina its got. I would like to put a little bit narrower tires on the front, dont really care for wide fronts, but might leave them on this one.
Once the hydrolic fluid warms up I'd say it easily goes as fast as a geared suburbans.

73Searstractor, could you post the dimensions of the cross piece for the seat brackets? That would be great, Thanks.

Sure no problem. I will get the measurements for you tomorrow, Its too dark to see right now. - Brad
Alright, cool thanks
Here you go SS/12. I got a couple pics of the bracket itself. Then I just drew a sketch of the peice with all the measurements. I used the bracket to trace the sketch, So if you print this out on a regular peice of printer paper you can use it as a template. The only problem you may have is making the little hump that the seat bolts to, That is necessary to clear the seat from the mounting bolts that connect to the seat springs. I would just make the bracket and then cut out a 3'' x 3'' plate and weld it on top of the bracket. That will be much easier than trying to heat and bend the piece. If you need anything else let me know. - Brad

Thanks for taking the time to take it apart and take measurements for me, its greatly appreciated. The additional pics will help too. I was also thinking of making it in three pieces and doing a slight overlap and fillet welding the edge to give it the look of being bent. I'll see about making this this weekend. Thanks for the help. I like the name you've given to your 19.9. Very fitting.
