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.
