The Deere Ztrak 540R uses a Tuff Torq TZ17-M hydro units. From the literature it stated that these are sealed
units and non serviceable but have an auxiliary fluid tank on the unit. I stopped by my dealer and confirmed this.
He stated that the Tuff Torq hydros in the 900 series do have filters for service. I have a Hustler Sport which uses the
Hydro Gear EZT which is not serviceable. The Z300 series also uses the same Hydro Gear EZT units.
As much as I like everything about the Z540R and the Z535R I am very concerned that such a larger and
heavier machine cannot be serviced like most of the competing mowers of similar size from SCAG, Toro etc.
Should I be?
As a side note: While searching I went to the Tuff Torq website and they have no info on the
TZ17-M and D models that Deere has in their literature.
They describe similar units but with different model numbers as TZT-7 Type II and TZT-7 Type III.
