I have that same Cub Cadet 524 that I picked up basically new for 80.00 .... only thing I did to it was clean the carb, install poly skids and put on an impeller mod, as the gap was very wide from the factory on those. Those zero turn levers are great and actuated at each wheel ... still uses the friction disc drive. I never had any problem and never had a reason to dismantle them.
I still have it in my fleet, and could sell it all day long for 500.00 here in CT.
