My 422 would not start in 15 degree weather replaced spark plugs and still would not start, I found ice in the fuel line and filter was blocked I cleared that out and it started right away

Interesting idea. I'm not sure just providing a bypass path for the hydrualic oil would be good enough. Since it's an open-center system, the only resistance it's seeing now is pushing the oil through the hoses and valves, right? And in theory, the hydrostatic drive pump doesn't even do that...if the treadle is centered the oil is never forced out of the pump. For the gear pump, the oil is forced through the hoses and valves then back to the reservoir without doing any work. I suppose pushing it through a much shorter set of hoses would lead to much less resistance. I gathered from an earlier post that the majority of the resistance seems to come from the hydro-static drive pump...I guess just spinning the fixture that holds the pistons in the cold thick oil is high resistance.
In the other thread I started before I saw this one, I was thinking of possibly replacing the couplings to both pumps with some sort of centrifugal clutches. That way you could crank the engine with no resistance from the pumps, then when you increase the throttle, the pumps would engage. The only problem with this idea is that the clutch connecting the hydrostatic drive pump would need a way to "lock it"...otherwise you wouldn't be able to bleed the HS pump by unplugging the spark plugs and cranking the engine to slowly turn the pump.

Leigh: I haven't gone back and reviewed the whole thread, but your post may be the first mention of water/ice as the culprit. We all should have thought of it earlier, since a little water in the fuel is far from unusual, and ice sure will plug a filter.
A filter change and a bit of dry gas is probably a good idea for anyone having slow start problems.

Open center!!!! DOH! You are correct. I blush in shame /forums/images/graemlins/blush.gif

No blushing necessary... /forums/images/graemlins/wink.gif
Just out of curiosity, does your IH have open center or closed center hydraulics? I'll bet it has closed center because I *think* bigger machinery usually has closed center. To my understanding, this is because they tend to have more hydraulic cylinders, etc., that would be used simultaneously, and open center generally restricts you to one or two simultaneous independent operations because two or more combined generally exceed the relief valve settings, etc. (You've probably witnessed this when trying to turn and raise the bucket simultaneously, etc.)

I can't remember... I'll have to check. I'm pretty sure they are open center.
On the PT, I get lift lock when I have the steering wheel cranked all the way to one end or the other.

If Amsoil is used a heater will not have to be used.

Why don't you send me 10 gallons of that stuff gratis so I can do field tests for you? /forums/images/graemlins/tongue.gif
Just kidding. /forums/images/graemlins/laugh.gif
Better yet, send it to Paul where it actually gets cold. /forums/images/graemlins/wink.gif

Best ship in a heated box so that I can pour it out. /forums/images/graemlins/grin.gif

It's a balmy 21 degrees here this morning. We have a winter weather advisory issued(no kidding... they expect winter weather in winter) from 1PM this afternoon until 4AM Friday morning. I guess after that winter is over /forums/images/graemlins/tongue.gif
On a lighter note...
I put the half AMP trickle charger on the tractor for a couple of days. The other morning I went out at 5 degrees, removed the charger and gave it a spin... fired up almost instantly. So, I suspect the battery isn't holding a good charge for a long period. Hopefully the trickle charger will keep it topped off for the rest of the winter and I'll see how it goes over the summer. Then, next fall, I'll forget about it and the first cold snap I'll be replacing the battery while thinking of this post! /forums/images/graemlins/wink.gif
