3 point hitch - drooping

[lspringeradelphianet]

Hi Zetor Folks

My 6245 3PTH arms when carrying a load start to drop down , then kick back up. Seems to be getting worse. I assume I have some leaking o rings or seals. Anyone familiar with doing a fix for this. Do I have to pull the whole CAB off? I imagine I need to pull the lift arms and cover off.
Thanks

i would think that the hydraulic ram is leaking internally, hence it leaking down. the position sensing mechanism corrects this when it drops out of the correct range which explains why it jumps back up. im not completely sure, but i dont think you have to remove the whole cab only the rear seat and floor. im pretty sure this is the problem but it would be good to get a second opinion from one of the more established zetor guys on this forum

this problem can also be the assister ram leaking. not the main ram inside. had the assister ram leaking on a 7745 and it started to do this up and Down you describe. changed seal and never had prolem again.

Thank you all

I'll try replacing the external assist cylinder seals first and see if that does it.
