    Power Take-OffThe 3YM30 engine has front power take-off (PTO) capabilities.

    Operating Condition:

    1. A-type shows an example with an overhang distance (L) of 30 mm (1.182 in.). When the overhang distance differs in value, calculate the capacity with the following formula. (Limit of distance is 50 mm [1.97 in.])
