Because of all the extra work involved I am not worried about fitting hydraulic hitch.yeh spot on @craig .. 3 x cetop3s, manifolded, in me VA-r plus a hitch valve too ... fed by a prop. aux pedal ...
buttons for tilt, rotate & Aux .. toggle for the hitch function .....
the issue is finding a small enough rotary coupling to transfer the fluid to the lower half of the set up ... I found Roemheld make some excellent rotaries ... 2, 4 and 6 gallery .. but at a price ... they can be found on ebay s/hand at a lot better rate than new price though
this is a 2 gallery https://www.ebay.co.uk/itm/Roemheld...051670?hash=item4219d24316:g:qFQAAOSwZtNa1ilY
this is a dinky one and cheap too ... 2 gallery though https://www.ebay.co.uk/itm/Roemheld-New/133141829556?hash=item1effdf17b4:g:Y4IAAOSw5cNYfSLz
and a 6 gallery ... not seen one like this before . https://www.ebay.co.uk/itm/Roemheld...094100?hash=item1ef8237c94:g:YR0AAOSwNSxU2U1n
.. my four and six gallery spare ones I have are all the same as the first link but taller ... the one I have in my VA-r has been performing fine since it was installed several years ago
ON EDIT ... that first link looks like a 4 gallery on closer inspection ... has an A and a C port so must be 4 gallery
'bout a quarter of new price that
