Mog is ag spec with a 3 way tipper and a cascade box. Chippers a tp 150. i can load that box to the top and its fine power wise although its a bit boat like on tight corners but you just slow down for that. i believe you can fit an anti roll bar and it helps the stability.
i will be fitting a winch to the front first though, nothing fancy just something to aid the pulling over of trees not for skidding out timber.
i seen your 406 on arbtalk. cool mog with plenty potential.
