I think manufactures are just worried about ease of assembly on factory assembly line with little thought to repairs later. When it comes to ATVs and UTVs the customer are going to repair them whenever possible as you just don't throw away 8-10 thousand dollars machines.
I had the last ZTR customer spend 2,500 on a John Deere 925A Z-trak to get it back up and running. That one required removing both transaxles as they bolted together as one unit so I could just replace one of them. 10hrs of shop time. No way to remove the bolts otherwise. And it required a shop crane and two jack stands to do the job beside the other tools.
