Does such a mower exist?

Just moved to a new house with a much larger yard (wife got a new job in a new state)

I am going from a 6000 sq ft (.14 acre) flat yard to a 1/2 acre yard with a medium grade in the front and a slight grade in the back. My old electric push mower (and my body) are not up to the task.

Looking for my first ride on mower but I have a limited storage can only fit a 30” mower.

Does a 30” ride on mower exist that can handle medium grade hills. Most I am seeing most are about 10.5 hp which is, according to reviews, is not enough for medium grades.

Oh, and my budget is $2k, maybe $2.5k

Any suggestions would be amazing.
