Why would new front tires make this tractor shimmy much worse? Where should i start to fix it. Happens on a road at higher speeds.
 
Odd, my experience was just the opposite.

The front tires on my TO 35 were worn down, it would shimmy on the blacktop. I gave it some toe out and that stopped the shimmy on the road. I later bought new tri-rib front tires and was able to set the tires back to approximately 1/4" toe in an now it drives fine on the road.

Note to file: be very careful if you try to tighten up the old steering gearbox, you do not want to bust a gear.
 
Well, when you think that tire shops balance tires for high speeds, not slow... I would start there. You most likely have a bent rim that isn't noticeable at slow turns, but if this just started since you got new tires, you got to have them balanced the old fashioned way, for the old fashioned reasons... btw, might want to loosen them up, see if they just weren't put back on flush, that would be the cheap easy lucky fix huh?
 
Old timer tire man trick, let the air out of the tire(s), get the tire free from the rim (you don't have to completely dismount the tire from the rim), rotate just the tire a half a turn, then air it back up. You can do it with tires with tubes but it will take more work so you don't damage the tubes. Sometimes it works, sometimes it doesn't.
