Hello all!

I have been searching high and low for an answer to this. I went out to my Brutus HD PTO to plow, started it and lo and behold the low hydraulic fluid light is on. I am baffled as to why because I don't see any evidence (stuff is dyed a bright color I am told). Dealership serviced it and "supposedly" topped my fluids off. Any ideas?

Thanks much!

The Hyd Fluid should not be coloured. It is just oil coloured.

Under normal operation there is very little loss but never the less it does slowly deteriorate or disperse here and there. The biggest loss, normally, is when connecting new attachments like the plow, blow or mower, that use the fluid to operate. Especially if the attachment has never been used before. It will fill itself for the first time from the machines reservoir. There's a little bit of loss at the connectors each time you connect/disconnect such attachments as well.

Well, I think I gained some insight to my problem and to be honest, I am kind of irritated. Dealer did maintenance on it at beginning of winter time, replaced hydraulic filter but did not top off system. I suspect this is why I ended up with the problem I have now.

Owner's manual requires 2879746 POLARIS Hydraulic Fluid

I was looking at my Bobcat manual, and Bobcat's part # is 6904026, the same oil used in other "Bobcat Compact Equipment",

Interestingly, the Bobcat 3650 manual gives a list of recommended fluids for use in the hydraulic system, including ISO VG 46 hydraulic oil, which is considerably less expensive than Bobcat ($40/gallon) or Polaris ($31/gallon).
