Have a Woods Batwing finish mower model 9204RD-2 Issue: L/R wings will not move enough to lock into transport latches without manual help It use to be only the left wouldn't latch without help but now it's both. Noticed today that the piston on the ring has not retracted and has at least 1 inch of the rod showing. The cylinder on the left has maybe 3/8 inch showing. The rear wing latches every time without issue Got to think what could cause this. I'm assuming one side is hydraulic fluid and the other side is just air. There are no leaks on cylinders. What might be the cause? The nut is backing off on inner piston or something else
I don’t think it’s a piston coming off or you should have oil leaking out the air / barrel side. Is it possible there is debris in the bottom of the barrel stopping full travel? Try putting the wing on the ground then pull the rod end pin and see if it will fully retract with no load.
Not sure about pressure drop, don't think so because everything else I use seems to work same as before Another guy mentioned that it could be that the piston is leaking fluid past the seal to the bottom. With no exit this could mean it just reaches the point were it can not move anymore due to oil on both sides I tried removing the bottom plug (where a dual action hose would connect) with 3/8 ratchet but could not budge it. Going to try again tomorrow with a breaker bar
Mine has a ‘breather’ on each wing cylinder. Ever so often, a little oil is purged on lifting wing. Mower before this one, one spring, would not lift either side…until we figured out it was oil locked. Removed plug you are getting ready to, all was good. Best of luck with yours.
It should have a breather on the bottom. It probably is building up some oil in the bottom that can’t get out.
Thanks No breather just a pipe plug, and when removed and cylinder retracted it belched out some oil. Going to drill maybe a 1/16 hole in the plug for now
