Hi I have a 4 year old Z Force S 48. (cub cadet) For the few months it has been getting harder to start. Recently it wouldn't start at all. It was acting as if the battery was low and it would just "click" until it caught and started after several tries. The battery has a full charge. I removed the key switch and solenoid and had them tested at the Cub Cadet dealer and they are OK. I re-installed them and jumped the contacts on the solenoid and the machine started. However when I tried to engage the blades it would die. I jumped across the solenoid again and put the switch in safe mode (for reverse operation) and the blades engaged so that I could mow the lawn. Can you tell from this where the problem is? Any help would be appreciated. Key switch does not do anything.
