Make the change of hydraulic oil to a Hew Holland TT 75 and the Em-Peso Em-Peso team with a problem of not holding, upload and down and when the tractor goes out immediately empies down to lower will be the seals of the Alce cylinder or ???? Grasias for your help
Look to see that the circuit is purged, because if it has air or lacks hydraulic it makes you what you say; Another thing is that he did it before changing the oil. Some maneuvers to rise to the top and lower and then check it the level. Greetings!!
