The Gannon 3 spool Hydraulic Top and Tilt Kit ties in to the power beyond circuit. The price in Sept 1999 was $1150 including the 3 valves, 2-(top and tilt) 4" cylinders, hoses, and installation. The placement for the valves on the fender is very natural when doing fine grading. The standard kubota valves seemed hard to reach for me (I have been told that I am not a small guy).
