Extra reliability and long life with cast-iron blade spindle housings

On every commercial mower deck there are three 1-in. (25-mm) spindles that are cold-forged and heat-treated for strength. Spindles are supported by precision ball bearings that provide great performance and reliability.

Superior impact strength provided by ductile cast-iron material.
Gusseted design puts reinforcement where it is needed.
Strength of cast iron protects against damage from blade impacts.
Easy access grease fittings are mounted at the top of the spindle shafts for convenience.
Grease pressure-relief valve minimizes seal damage from overfilling with grease and keeps debris from entering housing.
Chance of deck shell damage is minimized with the 8-in. (20.3-cm) diameter housing and six mounting bolts that distribute loads and impacts.
Ability to be reliably rebuilt is provided by use of cast iron.
