Every component of the RC60-B mower deck is mapped here, from the PTO universal joint to the lift arm assembly, with factory part numbers and exploded views across 31 pages. Fourteen pages of indexed parts lists walk the drivetrain end to end: bevel gear case, center pulley, tension pulley, blade holders, and both side pulley assemblies. Another 8 pages break down the chassis, covering the mower deck shell, wheel stays, linkage, discharge chute, and lift linkage for both standard and HST-type configurations. Match the multi-belt on your first call (size 118 inches), with each blade listed at 1.6 kgf (3.52 lb) so the spec is right in front of you. Bookmarked and keyword-searchable, it opens on any device and rides out to the machine with you.
