The Z915B is available with a choice of mower decks:
These mower decks use a vertical-shaft engine; the clutch is located on the bottom of the engine with the belt extending from the clutch to the deck and is turned on/off by an electromagnetic clutch.
On every John Deere ZTrak mower deck there are three 1-in. (2.5-cm) spindles that are cold-forged and heat-treated for strength without bulk. The spindles are supported by precision ball bearings, providing great performance and reliability.
The spindle housing is made of aircraft-grade ribbed cast aluminum. This unique casting design embosses reinforcing gussets in the housing, which adds both strength and cooling surface area that stands up to commercial applications.
These spindles can be greased from the top and require no disassembly to reach. Grease channels provide lubrication to both bearings.
The Z915B is powered by an air-cooled, vertical shaft engine:
Engine features include:
The hydrostatic drive features two 13-cc unitized hydraulic pumps combined with commercial-grade, heavy-duty wheel motors into a single unit.
One pump and one motor drive each wheel on the ZTrak B and M Series Mowers. This provides several benefits:
