eyes and clothing. Protect your face, eyes and clothing when working with a

for riding mowers. To assure optimum performance and continued
safety certification of the machine, use genuine Toro replacement parts
and accessories. Replacement parts and accessories made by other
manufacturers may result in non-conformance with the safety standards and
the warranty may be voided.
17. When changing attachments, tires or performing other service, use correct
supports, hoists and jacks. Make sure machine is parked on a solid level
surface such as a concrete floor. Prior to raising the machine, remove
any attachments that may interfere with the safe and proper raising of the
