HYDRAULIC SYSTEM
The hydraulic system on your FINN HydroSeeder® is designed to give trouble-free service, if
maintained as required. The most important areas of maintenance are the hydraulic oil and filtration.
The reservoir holds 22 gallons (83 L) of hydraulic oil. The hydraulic oil should be replaced per the
lubrication schedule or if the oil becomes milky or gives off a burnt odor. The hydraulic oil filter must
be replaced on schedule with a 5 micron absolute filter (FINN part number 008703). The hydraulic
system relief is factory-set at 2,650 psi (18,271 kPa).
At time of manufacture, this unit contains Finn Vulhydra hydraulic oil. The chart below illustrates the
operating temperature range of the Finn Vulhydra hydraulic oil as well as the closest ISO equivalents.
NOTE: The Finn Vulhydra hydraulic oil may be substituted for either of
the two ISO oils listed below. Please use the temperature chart to
determine what oil works best in your situation.
