I need a tough push mower

I need to purchase a tough push mower. It will be used primarily to mow my river lot, and some for trimming around the house & flower beds.
The river lot is rather rough. I'm wondering if the mowers with the huge back wheels are any easier to push & pull on bumpy ground?
I will be getting the power assist which helps move the mower but their are still times you have to push or pull it to get the job done.

Any brand recommendations or pointers on what might work well for me would be...
