I recently purhcased a bobcat S175 used (460 hrs). So far I have been just using the bucket for snow removal. But in a few more weeks when spring hits I will be renting attachments (and probably purchasing a snowblower for next season) that use the auxiliary hydraulics. So I have not hooked up anything there yet. Is there some sort of test I can do just to make sure everything works before I get an attachment out to the house only to discover I have an issue with the auxiliary hydraulics?
