Claim 17:
18. A drive assembly for a work vehicle comprising:
a drive housing comprising at least one housing element forming a stationary reaction member;
a first drive shaft rotatable about a drive axis relative to the stationary reaction member;
a planetary gear set coupled to the first drive shaft and configured to selectively rotate an output element, the planetary gear set having a first-stage sun gear coupled to the first drive shaft, a first-stage carrier, a set of first-stage planet gears supported by the first-stage carrier and engaging the first-stage sun gear, a first-stage ring gear circumscribing and engaging the first-stage planet gears, a second drive shaft rotationally fixed to the first-stage ring gear, a second-stage ring gear, a set of second-stage planet gear circumscribed by and engaging the second-stage ring gear, a second-stage carrier supporting the set of second-stage planet gears, and a second-stage sun gear engaging the set of second-stage planet gears;
one or more input clutch arrangements configured to selectively interact with the planetary gear set to effect a rotation speed of the output element; and
a control clutch arrangement interfaced with the planetary gear set and the stationary reaction member, wherein the control clutch arrangement is configured to selectively decouple the planetary gear set from the stationary reaction member to damp a torque transmitted to the output element.
