Abstract
A method of controlling a machine drive having a driveline PTO establishes a driveline torque perturbation via conversion of internal inertia through two transmission neutral conditions. In an example, when a request is received, e.g., from an operator, to shift the driveline PTO from a first mode to a second mode, the transmission is automatically modulated between its first neutral condition and its second neutral condition while the driveline PTO is shifted from the first mode to the second mode, thus minimizing torque lock and facilitating mode changes.
