I like the operation better on the Ferris because:
The handle bars on the Ferris are in a more comfortable spot which allows the arms to be down naturally which eliminates the possibility for back/ shoulder pain.
The hydros feel better.. The machine seems to handle smoother than really any other walkbehind out there today.
the ferris in my opinion has been easier to handle.. simple controls (cruz control bar and two handles that require light fingertip pressure).
I've ran this ferris for going on 3 years now and its been a great investment and I do use to have back pain and this machine has not caused any pains.... and its a hell of a lawn cutter and is really low on maintenance costs.
Its a little bit more money but you get what you pay for and at the end of the day you want to be cutting more grass and making more money with less hassle.
