I think you guys are right - it's a 641 with dual hydraulics.
This has been sitting in a garage for a bit.
Reverse on stick is up to the left, first to the right, I believe 2nd is down and 3rd to the bottom right.
I was able to get the blade in front to raise, and the bush hog behind was being stubborn - it eventually went up - almost as if the hydraulics had to be pumped up or something.
The choke didn't have a knob on it, but I since found where it was at.
At first run, in the drive way - I accidentally ran it out of gas.
It seemed to be starving for gas and had a clear fuel filter that I replaced. I removed the screw from the bottom of the carburetor and some crap came out of that.
When I ran it out of gas - it sounded great. Do you guys think I pulled crap into the carb?
Had trouble getting it started again - charging the battery overnight.
Some kind of guide on this thing would be great.
