John Deere 240 disc mower

I know the 240 is a older mower and not very wide. I have some steep hills to mow so I’m looking for a lighter mower.
What can you tell me about the JD 240? I noticed the one I seen for sale locally doesn’t have a hydraulic cylinder. So I’m not sure how you would transport it.

Is there any way to add thicker shoes to the 420 to make it cut higher? Right now I’m using a drum mower and I hate how low it cuts.
