Just a dumb observation and question...Growing up we had a 147, now I have a 149. I remember coasting down the big hill we had out back with the hydro release lever pulled and letting it go after about 200 mph and it would lock the tires up. Not that that is recommended but we were dumb kids and kids tend to beat their dad's equipment when their dad's aren't home. With my 149, I've never have to pull my release lever to push it around...you can move it around freely. BTW, the 147 ran good until my dad traded it in on a gravely. Never had any hydro problems...Just wondering if they changed something or if my 149 has any problems. Thanks, Nick
