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 image. These bypass levers serve as a
neutral for moving the mower while the engine is not
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.
The images to the right show the location of the
push rods.
