Is there a position control like one for depth and draft control and another for float on the 3pt? I bought an 830CK in June. Now using it on an 8ft. blade for snow. I have a U 302 Super MM that has the two positions in the 3pt. lever. Upper part is float and lower part is depth. I see there is a long flat lever under the seat on the floor board that has three holes in floor to adjust it. I was wondering if that was it? The hydraulics on the MM are acting up so I put the blade on the Case.
