MtnViewRanch said:I'm sure with a few tries that you will have it figured out.I'm guessing here, but if it were me I would get the cut depth set with the 3ph and then set the gauge wheel down so that it just touches without lifting the blade. Then you should be set to go and anytime that you lift the blade, only use the 3ph and as long as you always lower the hitch back to the same position with the position control you should be good to go again, I think.

Good luck and keep us informed. Oh yeah, remember the pics.![]()
Actually, from the RBT45 manual...
The gauge wheel provides accurate depth control when
grading, leveling or terracing. The height of the gauge
wheel is determined by adjusting the ratchet jack or
hydraulic cylinder.
Hydraulic Gauge Wheel Adjustment
1. If the gauge wheel cylinder is attached to the selector
valve, make certain the valve lever is set to operate
that cylinder.
2. Operate tractor control lever to change gauge wheel
height up or down.
IMPORTANT: The top center 3-point link can be
removed from both the blade and tractor before
using the gauge wheel accessory with the blade.
So...
You actually completely remove the center link from the 3-pt to use the gauge wheel correctly.
Normally with a rear blade, as the front of the tractor goes up or down a hill or "whoop" in the road, the tractor rotates around the rear axle and the blade is forced in the opposite direction. By removing the center link and adding the trailing gauge wheel to control the depth of cut, the system acts much more like a road grader.
