Hydro help

alpinebigfoot · Feb 29, 2016

I took the snow plow off the tractor 186D. Pto hitch will not go up now so I looked and the fluid is really low. I pulled the dip stick for the hydro fluid and all the fluid started throwing up out of the hole. The tractor is cold and was not started today. Why is this happening? Thanks for the help Yanmar gods!

Fluid throwing up out of hole after filling to correct level?

No. I knew it was low. I got some fluid today and was going to add some. I checked it to see how much to put it. I looked back and it was puking

Anyone? Should I just drain it all ? How can there be pressure in there if the tractor has not been started?

I am confused, nothing unusual about that though. Wondering if your pump is picking up air and if so it would puke through the return into the transmission. Maybe just needs some fluid? :confused3:

I unplugged the snow plow is there a valve or something to shut? It was just 2 quick disconnects.

I don't know how your snow plow is plumbed. If there is a control valve before the quick disconnects then unplugging them should have no ill affects. If the two disconnects are before the control valve then you may have dead headed your pump.
