i bought my ferris used and it had ag/bar tread tires on it....i thought it looked horrible! my buddy, that had just bought a new bota ztr, told me i was crazy for wanting to go back to turfs and that he'd love to switch his to ag......
well, being cheap i didn't and now have gotten used to the ag treads.......i had alway heard how bad ztrs were on hills, especially going across them......well, let me tell ya, i love this thing on hills.........i just add slight amount more on the oposite lever and it honestly has no trouble..........
i can say, however, that i can really see how they would be scary/dangerous on hills with turf tires and i wouldn't want to get on a hillside where i didn't have an escape path (you know, if you go down the hill you roll in to a ravine!).....
and, before you say it- because i did- the ag tread tires don't tear up the ground......i don't know whether mine are worn out or specially made but the bar lugs aren't that deep.........
i'll most certainly put ag/bar tires back on it......
