In case someone else needs this information, I just discovered the 7000 series uses a Sauer model BDU15 Hydrostatic Drive pump and according to thier web site in the
BDU15 Manual it states:
Fluids
Ratings and data for Sauer-Sundstrand products are based on operating with premium hydraulic fluids containing oxidation, rust, and foam inhibitors.
These premium fluids include API CD engine oils per SAE J183, Type F automatic transmission fluids, power shift transmission fluids meeting Allison C-3 or Caterpillar TO-2 requirements and certain specialty agriculture tractor fluids. For further information, con- sult Sauer-Sundstrand.
At continuous operating conditions, fluid viscosity should be above 55 SUS (9 mm2/sec). Minimum fluid viscosity should be above 45 SUS (6.4 mm2/sec) at intermittent operating conditions.
I have been using the premimuin fluid at Tractor supply for my 7254 for the past 3 years with no problems.
