    Merge divider is because the tracks don't work on independent way . They only work together and the swing work slow. The tracks and swing improves when I use the bucket arm or boom.

    You should put some gauges and test the machine otherwise it is gonna be really hard to repair it

    I had checked front and rear pumps and the pressure is 370 bar in both. When I use every functions exept the tracks and swing on independient way. I think it is due to a deficiency in ps pressure in these moment.but I don't how to check it because I haven't a hydraulic diagram and check points location.

    The swing should be like all the other work equipment. But here you have both swing and travel problem so I do not think the divider is defected. Anyway it is not a classical behavior so try to call an expert at least to know where to start.
