We just got a new 299d3xe and are trying to run our older attachments, specifically a FAE mulcher head and a Davco feller buncher. Both attachments have hydraulic lines for high flow and low flow and use both for separate functions. High flow for the cutter heads and low flow for a feed door on the mulcher head and for accumulator arms on the feller buncher. We have figured out the high flow jumper but are running into issues with the control operations in the cab. It seems as though the same buttons are controlling the high flow and low flow, so you can spool up the high flow turn the continuous flow on but then the only way to control the feed door is the same button or toggle and that shuts the high flow off.
I feel like we are just missing something. We've run both attachments fine on our Terex machines but that has specific on or reverse buttons for the high flow and the low flow functions are controlled with the toggle button.
Any help would be aappreciated!
