Backhoe hydrolic oil

[paulie]

Need to change hydrolic oil. See my b21 has a hydrolic filter and the hst transmission filter. Is there just one drain plug for the common tank? Also is there a specific position the loader and the bachoe should be in to check the level of the fluid? Thanks in advance.

On my b7510 it is one resevoir with two filters and you are supposed to pull out the bango bolt on the suction line for the hydraulics and clean the screen on it. You should try to find an owners manual it's hard to figure out some of this kind of stuff and the adjustments without one.
