What can I expect to pay for this?

Its a 36" with sulky. He wants it gone asap so he can buy a ztr. He says the only thing wrong is weak starter or voltage regulator and needs a new pto. Doesn't know how many hours is on it. He has a cover for the deck, just took it off for pics. View attachment 333075 View attachment 333076

As the title says, what's a good price and what can I expect to pay for the 2 items that need replacing.
