Hello everyone  :wave:
 
Iam new here and hope I can get some help to get my little tractor going.
 
I bought a  gilson hydro 16 with hardcab, snowblower and snowblade to hopefully have more fun when plowing/throwing snow than with my regular walk behind snowblower :) Also hope that I can push some gravel and pulling a cart.
 
Gilson hydrostatic 16
Briggs and stratton
Model: 326437
Type: 0135 03
Code: 74 ...
 
Vickers t66 hydrostatic transmission
 
 
Wont go forward
Wont go backward
Raising/lowering attactchments wont work
Brake/(clutch?) wont work
Parking brake wont work
 
More or less everything that is driven by the hydraulics wont work?
 
I can push it forward and backwards even when brake/clutch is pushed down fully, forward or reverse is in or/and parking brake is on. Also when moving tow valve control up/down nothing happends, can still push it by hand.
 
 
 
So where do I even start? :)
 
Should I change oil and oilfilter, and see from there? (I read that this can get it going although I think its not that simple).
 
 
I have another gilson for cutting grass, but no hydraulic, so iam new to that.
 
When using hydraulic, Should I be able to hear that?
If so the pump/motor is not working? since I cant even hear it "trying".
 
 
Thanks

you can look in the manuals section while we are waiting for some Gilson folks to chime in. Never owned or worked on one myself.

If you're not hearing anything from trans, I would 1st verify that it is indeed pysicaly hooked up to the engine. Not knowing your brand off hand I can't say for sure, but look for broken/missing belts, loose linkage bolts, loose or broken driveshaft rag joints/universals, stripped keyways, or anything that is not turning from the engine back. Some pictures will help us help you better, and the more, the better! Welcome to GTT:)

Sounds like low or out of t fluid. And your tow pins stuck. With the tow not engaged you should not be able to push tractor. That is if your drive shaft is working as Stiemmy said.

Thank you all for welcoming me and for the help :)
 
I cant hear anything at all when putting in forward or reverse. Cant hear anything either when trying to raising/lowering attachment.
 
 
9. I think it should be pysicaly hooked up to the engine, shaft seen in picture 9 is spinning like crazy when motor is running.
10. This is the tow pin right? I can move that handle up and down and you feel it "click".
11. Is this where to fill it? Is it possible to fill it too much? When opening that its a spring and a little ball there
 
 
 
Sorry for all the dirt. I will give it a good clean next week :)

Is this that tow pin?

 

It is attached to that handle in picture 10.

 

I have been wiggle it a bit and pushed it in and out, but still can move forward and backward by hand however that pin is.

That is not where you check fluid that is a relieve valve, In your pic of shaft you can see the square head plug in t fitting. You turn the pipe up till filter touches bottom of pump. Fluid should be at bottom of the hole when you take plug out.

Ok thanks.

 

Do you know where to fill it with oil?

 

I have opened that one you are talking about, and its full of oil dropping out.

That is where you fill also. Did you lift pipe till filter touches the bottom of tractor. And as said make sure all linkage moving? Its easier fill with tire removed and jack up a little. 


  • stiemmy said thank you

No I didnt lift pipe anything, just opened that screw some days ago.
I took some pictures under there you can see below.
 
Also, look last picture, is this that tow valve/pin?
When that tow pin is in or out, it should not be possible to push tractor by hand?
What if it is to little oil in, does this tow pin stop working then?

That is a good couple of manuals to have. That is the tow pin if it snaps it's more than likely working. When you raise the filter pipe a couple inches makes a lot of difference in amount of fluid in pump housing. Yes if to low on t fluid there is no fluid pressure to bypass with tow pin.

I got that first one, but "Gilson Service" I have not seen and it had much good information. 

Thank you. Appreciated!

Alright, Thanks. I will update here when I have cleaned it and changed oil.

 

Btw. Should I buy so much oil so that I can flush system once with new oil, and then fill upp with new again?

Yes and no. Yes if fluid looks bad and you can get movement after filter and fluid change. No if no improvement after change possible pump damage or stuck valve.
