SERVICE SECTION
SECTION 1: HYDROSTATIC SYSTEM
The hydrostatic system on MZ models is a sealed lifetime
transaxle system, so no maintenance is required.
Under the rear of the mower, you will find the two levers
shown in the images. These bypass levers serve as a
neutral for moving the mower without the engine running.
Pull the levers out and lock them into place to activate the
bypass.
When adjusting the tracking on the mower, the length of
the pushrods can be changed by screwing the swivel joint
in or out on the ends of the rods. Shortening the overall
length of the rod slows the pump down. Lengthening the
rod will increase the speed of the pump.
