voltage. If the battery voltage is satisfactory, check the cleanliness and tightness of the terminals and ground connec-
tions. A general understanding of electrical servicing and use of basic test equipment is necessary for troubleshooting
and repair.
Major overhaul or repair of the starting motor or charging system should be performed by trained technicians only.
Access to ZT2800 transaxles
The integrated pump/motor units are accessed by lifting the seat platform. The seat platform is hinged at the front.
To raise it, remove the lock nut and tilt seat platform up and forward.
If the seat is equipped with the optional arm rest kit, make certain to place the control arms in the park brake
position and pivot the arm rests upward before placing the seat platform in the full forward position to prevent
damage to the arm rests.
Hydraulic system
The FasTrak 48/54 is equipped with two Hydro-Gear ZT 2800 transaxles (FIG. 38).
IMPORTANT: Never use hydraulic or automatic transmission fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic system.
The hydraulic expansion tank is located in front of the engine and under the operator’s platform (FIG. 40).
Check oil level in hydraulic system prior to each use. Check more often if system appears to be leaking or otherwise
malfunctioning.
Fluid level should be at the “Full Cold” line on the expansion tank. Use only SAE 20W50 SL service motor oil.
Change the system oil and filters after the first 75 hours of use or 1 year whichever comes first. Thereafter, replace
filter and oil in each transaxle every 2 years or 200 hours, whichever comes first. NOTE: The filter guard must be
removed to access filter.
Each transaxle’s filter is located per FIG. 41. A standard oil filter wrench is used to change filter, threads are right
handed. Use a Hustler approved filter element only.
