The shaft #9 is what the drum is on and what Norm was talking about. TRANSMISSION_INTERNAL: Yanmar Tractor Parts
And just so I know...what is the name of part #9?

Have you taken the bolt out ?? Hope it don't break off.. That thing is pretty rusty.. After you get the bolt out.. The drum is probably going to be rusted to the shaft
Is your axle housing built like the one shown on figure 57 in the 276 parts manual? Reference #2?
It took a LONG time, but I got the left brake cleaned up. Took a lot of juice and a wire wheel on my grinder but it actually looked pretty decent when I put it back on. I don't think I will need to replace anything but I will need to order another gasket for both sides. Anyway I tried my hopeful theory about the brake was locked up and causing it....wrong.Worth a shot and got me semi hopeful for a short time.
When I turn it on and put it in gear, both wheels turn but I can grab the left axle with a gloved hand and stop it. So it is only turning because it is not under any load. While it was running I also went to the right side and slowly pushed down on the diff lever while holding the axle from turning. You can feel the diff engage and at that point you cannot hold the right side.
I have taken the right brake off now and got it all cleaned up. Tomorrow morning I will put it back together and back in, shouldn't take but 30 minutes and then back to find the problem.
It looks to me like I have to take off the seat/bracket and the ROPS. Once those are off I can take the cover to the final gear and see down in there. At this point I am assuming that is where the problem is. I still believe it is something on the left side but when the drum was off (on both sides) the 4" end of the final spindle coming through where the brake drum was turns if I turn the wheel axle on that side.
Any suggestions that I am not thinking of? I'm not frustrated yet and have not taken anything apart that concerns me yet. The brakes were filthy. After cleaning, there is very little pitting anywhere and it isn't bad. The shoes are almost new thickness.
Thanks again guys
I have the pto cover off. Big ring gear on left and right off of axles. Main ring gear in center. If I turn the right axle it engages the spider gears and turns the big ring gear in center. If I turn left axle, the ring gear from it turns and but the main gear in center does not turn at all. Is this normal?Taking the PTO assembly off now. We will know shortly.
It took a lot of working around and trying different positions but the PTO assembly is now out. Time to check the gears....

Just for clarity I will call the large gears on the axle shafts "final gears". The large differential gear is called a ring gear and is driven by a pinion gear. Any chance of pictures up in amoungst them? Wondering if the bolts are sheared that hold the ring gear on the differential housing? Should be about six of them.
