Well, I have a couple of questions, I May have the opportunity to buy a 60 or a 620 there is both available maybe. I would need to run it some on the road where does one top end at?, a buddy said his dads 50 would run 15 but he is one of those people that may not know just exactly what he is talking about. The second is hydraulics, On the 60 do you have to shut the remotes off to use the rockshaft (3 point hitch)? And a third. I"ve noticed that the P.T.O. is off center on the ones with live power. Does that have any ill effects on the driveline such as wearing out u-joints faster than normal? Thanks for any help you can provide.
