| Some of our roads/firebreaks are so curvy that I use the inside brake to get through. Guess this makes the inside discs 'dig in ' and I wind up with a banked road. Any way to prevent this? Thanks! |

| Disc must be level side-to-side. Raise the front gangs up some and let the rear gangs pull the dirt back in. Less severe turns would help if you can. If you use the left brake going one way, I'd think you'd be using the right brake coming back ???? |

Thanks Dr Allis. I can try lowering the back gangs with the top link. Have to negotiate around trees in quite a few places and I do use the inside brake both ways. Not that big of deal but a level road would be nice I'll check my lift arms too. |

Lift the disc!!! 3PT equipment was not designed to go around corners. I know everyone does it, that is why so many of the 3PTs on D10/12/15 tractors are ready to fall out from under the tractor. If you MUST turn with lowered ground equipment make up some stabilizer irons like Ford tractors use. this will take some strain off of the 3PT. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

| Snap coupler hitch is actually better for contours and turning !! |

| Raising the disc would work but I don't want a gap in my firebreaks. My 3 point is an aftermarket Cross? , pretty robust. Doubt the D 15 could hurt it . I do wonder if a snap coupler disc wouldn't work better. Thanks! |

Being on the left coast everything is different,  as to growing things as well. So I am shooting in the dark. How often do you till the fire brakes, how much growth? Could you use an angle blade on some of your passes? Pushed the dirt back where it came from.Here we would run a old style offset disc without wheels. With hydraulic ram, we remove angle of set in the disc. So the only cutting action is from the turn with no angle of set in the disc. Even if you could find one in your area, no idea if the non wheel part would work at all for you. Again just differences in how things get done in different places. Not that ether one is best.

Any of the 3PT hitches except for the AC built (wishbone style) adapter as Dr. Allis mentioned will not tolerate turning while lowered with a working implement for long before the 4 bolts attaching them to the bottom of the housings will begin to loosen up. then once they are lose the damage begins. The Di5II I have was so bad when I got it the lift housing had to be replaced, luckily the transmission housing was savable. It is now a Snap-Coupler tractor as the factory 3PT went on the scrap heap.
