Why float valve for Boxblade tilt?

[wdchyd]

Adding float looks like a good idea, but how about adding tees at the top link hyd cyl fittings and connecting them together with needle valve between ports (basically does the same thing as "Hydraulink").... open the needle valve when float is needed....close off when not.....that way you don't have to mess with the control valve that operates the top link cyl.....of course you're dealing with different disp on each side of the cyl again, but wouldn't this be a less expensive alternative than the "Hydraulink"??

I don't see a reason for float on a top link other than with a rotary cutter. Before people get carried away with the Hydraulink, it looks to me that it is made for SCUTs. It is very small and only has a 4" stoke. Most CUTs and utility tractor top links have an 8"-10" stroke, or adjustment.

Yea, thinking about it again adding needle valve you are just making a S/A displacement cyl....Hydraulink must have an air pocket to allow the rod to retract in....

I installed a joystick 10 years ago to add two more remotes that I needed for a logging grapple. I have what amounts to a double top link set-up (one function of the joystick) and the other the factory remote control. The other function of the joystick (with float) is used for the grapple and w/a selector valve on the grapple, the winch. I put the float on these functions for a reason, If I am winching a log and need to relieve the stress for an emergency situation, float is in the same direction and saves the response time to reverse the joystick. That is how I use the float function in this situation. I also have a homebuilt back blade with down pressure and I use the float function there with the other function being the top cylinder which through geometry and design allows me to select between, above or below, the plane of the wheelbase track. Float is nothing more than equalizing the sides of the cylinder to allow gravity, or other forces in my case, to have their way. It was there so I used it to my advantage.

HydrauLink actually has a 6" stroke plus an additional 4 1/2" screw end for adjustments.
