Tiger Mowers JD 5085M-105M ユーザーズマニュアル

Assembly Section 2-12

Manual, cable controlled (Husco control valve) boom mowers require check valves 

with integral restricting orifice (#06502036) installed in the control valve work ports that 
are connected to the gland ends of the main and secondary boom cylinders.  This check 
valve allows oil to free flow into the gland end of the main and secondary boom cylinders, 
but restricts flow out of the cylinder, thereby providing proper boom control.  This check 
valve, #06502036(Vendor #1968R-.063) is similar in appearance to hose adapter #33271 
and Adapter #34396, with.06 orifice.  These components can be identified as follows, and 
are to be installed per parts section for the lift valve.
