Case 444 won't start

[Roadnuts]

Finally got her to crank over and start! As it turns out, something very stupid on my part. I re-read all these posts and decided to try checking the hydraulics. I found the rear hydro engaged and after putting it in neutral it cranked over great! Lesson learned. Just need to figure out why it stalls when that same lever is put "on"? Possible frozen valve? It seems to dead-head the hydraulics. Any ideas? Thanks to all for the great advice and wisdom.
