we do have a this two loader , the 950G even its just sitting idle or park its going down the bucket in 2 hours time while the 980 G goes down itself while in motion or even at work which is quite a problem for us
Almost sounds like your cylinders are bypassing or you have a problem in your lift spool valve section.
Thank you very much Chris will you be kind to send me some more info about this spool valve section and if you have some picture so I can visual check
you can me in my email [email protected]
First thing I would do is check to see if you have ride control on the hydraulics. If so turn that off and see what happens. Also if it is happening fast enough you should be able to hear the bypass( valve or cylinder). Another quick check on lift cylinders is see if one is noticable hotter than the other. That would indicate a bypassing cylinder. If you lower the bucket to the ground and lift the front of the machine off the ground what happens?
When I go back to work on tuesday I will copy some info for you. What is the machine serial # prefix?
Its Made in Belgium with serial # 9CM01869 2002 model for DRESSTA1: if i lift it up around 100 mm it will go down and bucket will tilt (for 950G) but in 980G it goes down in any position even while its moving.
It can also be the control levers in the cab that aren't centering when released, quite common. On the 980 you can take a load, raise and then flipping the implement lockout switch and see if it stops sinking
