What are the key specifications and installation notes?

The spindle height measures 6 15/16 inches and includes a pulley preassembled to the spindle shaft. Installation requires basic hand tools and following torque specs—reuse or replace mounting hardware and blades as appropriate. Check belt condition and blade balance while the deck is disassembled for best results.
