Cub Cadet SLT 1550 PTO Help

[dangerous]

I attempted to engage the PTO after changing the mowing blades today. The tractor started fine, but the PTO would not engage. I could hear is a clicking sound coming from the right side of the of the engine. It appeared that a wire moved when pulling the electric PTO switch. I need to mow the lawn tomorrow. Could anyone recommend a list of things to check? Thanks in advance.

Thank you for the reply. I know the steps recommended should have been my first actions. I was working too quickly yesterday and rushed to judgement that something could be wrong with the PTO switch/clutch/wiring. It turns out I had belt problems.

Thanks again!
