I changed the main hyd filter but the manual says there is a second hyd filter on T-Bar machines called (charge filter) on the left side of the chassis, beneath the ROPS/FOPS that should be changed with the main filter. This is all it says, no pics or anymore wording. I don't see any other filter without removing anything or lifting the ROPS/FOPS. Anyone on here know how to get to it? From under or need to lift enclosed cage? Thanks
