BP, yes, for now. A few teething troubles with this tractor. Got full crane power now with new pump, but didn't cure the odd steering symptoms. If standing stationary, cannot steer lock to lock at any rev. It gets so far fine, then goes hard and won't turn further. Both front and rear steering wheels same effect (it's reverse drive) , if put crane out back of rear wheels it goes a bit further towards full lock, if pick up a log out back it goes lock to lock. If move tractor a little, it goes lock to lock. Though it also seems to hesitate if you steer "without warning"! Which is scary in oncoming traffic.
We tried bypass test on steering ram and there was a small trickle bypassing. Various priority valves and such to check out next (when Mike the Mechanic returns) if that doesn't do it I suppose we'll change ram seals.
