I spent 2 hours on saturday studying the lawnmower frame and how to detach the rear transaxle. I found and removed 4 bolts that attach the transaxle to the frame. 2 came off easily. I had to cut the other 2 off. There's a belt that goes from the engine to a pulley clutch and another belt that goes from the clutch to the transaxle.
I can loosen the big belt with the clutch, but I haven't figure out how the belt comes off in one piece. There are tabs acting as guardrails that keep the long belt in place. I can't seem to remove the belt without bending the tabs out. Seems like there is another way. I'm going to do some youtube research before I do anything with that. I might not have to touch that anyway. Other than detaching some springs, I think the transaxle is now only attached by 2 more bolts.
I think if I undo these bolts, I won't have to mess with the belts at all.
I spent the rest of Saturday fixing my virtual model of the center truss. The IRL frame has 9 cross-members. My model had 10. I spent most of Saturday taking measurements and trying to make my model match. It's tricky, because I can't measure to the center of anything. I have to estimate based on the distances at the intersections.
I'm glad I did, though. I already have to shift some things around in front because of the slightly different geometry.
