Mushy ride / hard to turn

I bought the 2009 850d used about three years ago. Appeared to be in good shape and has served me well for easy lawn chores. But, now hauling wood. From day one, it's had a bit of a saggy ride even empty, seems more saggy on the left side. I notice lately when I am hauling firewood, loaded down, it's close to bottomed out. Of course, depends on how much and how heavy the wood. But wondering if it's 'normal' for a Gator to have a pretty mushy ride and if there is anything one can do about it and if one 'should' do something about it. I can live with it if it would be an expensive fix, lol. I am not where my Gator is or I would look. Is it shocks or springs or both?

This Gator has also always been kind of hard to turn. No biggie for me but curious if it's 'normal.' To make a big, slow turn, you gotta tug on that steering wheel.

Thanks for feedback on what is 'normal' for a Gator's ride.
