Should I attempt to adjust the hydro and neutral for my redhawk, or just take it to a dealer. I started it, and had it in neutral, and as soon as I moved the throttle, it started doing circles backwards. If the mower is under warranty will a dealer adjust them for me, or will I have to pay. There is a dealer down the road from me, but i did not buy the mower from them. If not how much should it cost to get the machine completely adjusted.
