That's a nice looking rig. Do you pull trees or shear them off? Any weights on the back or fluid in the tires? Any issues with hydraulics running more than one function at a time? Your tractor should be an open system. I don't know what the neighbor's Maxxum 125 is and he doesn't either. Can you run the loader and tree mechanism all from your joystick? Do you have sealer in your tires to seal punctures. Do you have mesquite where you are?
