Did you get a bleeder hose with your machine, and does it have a fitting on each end? If so, that should work for your bypass, too.
As for your engine issues, you were driving along and then it just slowed and stopped, and now you can't crank it with the starter? That doesn't sound good. With no compression with spark plugs out, with cold oil, you should still be able to crank it easily. Yes, your starter could be hung up in there, and I hope that is the problem, but..... anytime I've had an engine slowly loose RPMs and then lock up, it's been bad. Like seized pistons, crank bearings, out of oil, etc.... Let's hope for the best! :thumbsup:
Let us know how you do getting it out of the field.
Also, even with the bypass in, go nice and slow. When I had my bypass hose in, I was able to crank up the FEL arms off the ground with a ratchet strap, and then was able to push the machine around my driveway and garage very easily.
