kubota svl95-2s - loader arms fall freely - checked multiple things running out of ideas

[sepulchral]

kubota svl95-2s loader arm is falling freely.

If you push down on the ground you can lift the front end of the machine up and it will stay overnight.....

but if you raise arms a little they will just fall.

i checked float solenoid valve looks okay. lift arm spool looks okay. thought about bypassing in a cylinder but i would think it woudl bypass both ways correct? machine will itself off ground

i think i checked the float valve cartridge it looked good as well.


any ideas!!

I wasn't suggesting that someone pushed that lever...I was suggesting that whatever it is attached to may be compromised.

swapped overload relief valves, that didnt fix it.. ordered a bspp cap set to see if one of the cylinders is bypassing

i know. its a simple hose with an on off plunger valve. i did check the valve its normally closed, so its ok
