Claim 0:
1. A material collection system, comprising:
a vacuum generator comprising a fan to develop an airflow and draw material into a material inlet of a conduit;
a transmission to control a drive of the material collection system;
a power source to selectively power at least one of the vacuum generator and the transmission;
a variable power divider engaged with the power source and the transmission and selectively engaged with the vacuum generator such that an output from the power source is divided by the variable power divider into a first variable input to the transmission to control a speed of the transmission and a second variable input to the vacuum generator to control a speed of the fan; and
a control system to control an output speed of the power source, the first variable input, and the second variable input based on a first mode in which the variable power divider is disengaged from the vacuum generator and a second mode in which the variable power divider is engaged with the vacuum generator,
wherein in the second mode, the control system relationally controls the output speed of the power source, the first variable input, and the second variable input based on power needs of the material collection system.
