I haven't had a chance to do much in the last week. It's raining so much I can't get to my job.
I took it out to a little 1 acre job and went to work. With the new engine, and the new pump the increase in power at the head is huge. This little job was in the Pinon & Juniper, so nothing huge got mulched but I did do a couple of 6 or 7" Pinon's. I finished the 1 acre job in 3 1/2 hours.
The bug's

: The fan on the Deutz was a pusher. The fan on the Yanmar is a puller. I didn't think much of this until it got to about 140 degrees in the cab.

Evidently Yanmar doesn't make a pusher fan blade, so I'll have to figure something out. Maybe electric, maybe make the Deutz fan fit, or maybe move the condensers up top and see what that does.
Bug #2: I guess I've got something wrong in my wiring to the starter, because when I went to start it after doing an acre nothing happened. Feeding power back through the solenoid somehow. Total melt down! But that's ok, Yanmar only wants $750 for a new one.

:mur:
Other than that, it's working great, and I love it. It's going to be worth the effort in the long run, but in the meantime the Bobcat will be carrying the slack.
I'll let you all know what I do when I figure it out.
