Jinma 254 snowblower chute hydraulic question

[acadian32]

Good day all.

I purchased a snowblower for my Jinma yesterday with hydraulic chute however not sure how to make the chute work? I plugged the 2 hydraulic hoses to the blower and the only way it works is when I use the up and down control for the 3 point hitch because the chute has a bolt on the chute to stop the rotation at example 180 deg what happens is the chute will turn example 180 deg once it hits the stop bolt then the 3 point hitch will go up or down however the chute will no longer rotate and if I switch the hose connection reverse in other words then it will just do the opposite counter clock example 180 deg then 3 point hitch will go up and down but chute will now stay in the stop limit position. I was sure I would have a separate spool control to control those 2 hydraulic outlet at the rear of the tractor but I'm guessing no at this point.

Thank you all for your upcoming comments / suggestions / help.

It looks like you do not have the optional multivalve block therefore the 2 outlets you see on your tractor is a pressure outlet from the 3 point hitch and the other one is a drain back to the hydraulic oil sump. Normally full pressure will build when you raise the 3 point hitch to its max upward travel but in your case the chute will travel first to either full right or full left first because it takes less pressure to make the chute move then to lift the snowblower, so in your case the 3 point hitch will only lift after you hit your mechanical stop on the chute.

You'll have to Tee off the pressure line before the 3 point hitch diverter valve coming from the pump and install a separate diverter valve to be able to control the left/right function of the snow blower chute separately. On my Foton 254 I have 3 control arms, one is for the 3 point hitch and the other two control the cute left/right and chute up/down.
