Hydrostatic Drive System: General Information
The TIMECUTTER® series of mowers use Hydro-Gear hydrostatic transaxles.
There are 4 different models used; ZT-2100, ZT-2200, ZT-2200 long axle, and
ZT-2800. All the drives use the same type of fluid. The oil must have a minimum
rating of 9.0 cSt (55 SUS) at 230°F (110°C) with an API classification of SL is
recommended. A 20W-50 engine oil has been selected for use by the factory
and is recommended for normal operating procedures. An oil volume of 54
fl oz for the ZT-2100 and 56 fl oz for the ZT-2200 should bring the fluid to the
correct level in the transaxle.
See the Hydro-Gear manufacturer's manual for servicing.
