A power distribution assembly integrated into the lower engine housing of an internal combustion engine, the assembly having a drive train with a T-box output configuration and power take off driven by the crankshaft of the engine. The drive train may power the input shafts of a pair of independent, variable drive transmissions. In one embodiment, a single actuator engages a manual clutch/brake mechanism that controls the output shaft of the power take off. In other embodiments, an electric clutch affords control of the power take off mechanism. In further embodiments, a hydraulic clutch/brake assembly allows control of the power take off, and an additional hydraulic clutch assembly may be used to control the outputs of the T-box.

1. A power distribution assembly comprising: a housing comprising a first engine housing joined to a second engine housing to form a sump;an engine having a crankshaft, wherein the engine and the crankshaft are disposed in the housing;a clutch mechanism disposed in the housing, the clutch mechanism
1. A power distribution assembly comprising: a housing comprising a first engine housing joined to a second engine housing to form a sump;an engine having a crankshaft, wherein the engine and the crankshaft are disposed in the housing;a clutch mechanism disposed in the housing, the clutch mechanism comprising: a rotatable outer carrier configured to be driven by the crankshaft;one or more clutch plates secured to the outer carrier;one or more brake plates secured to the housing;a rotatable inner carrier configured to occupy a first position where the inner carrier is engaged with the one or more clutch plates and a second position where the inner carrier is engaged with the one or more brake plates;a spring biasing the inner carrier away from the first position and toward the second position;a rotatable shaft driven by the inner carrier; andan actuator assembly having a first end disposed inside the housing and a second end disposed external to the housing, the actuator assembly configured to occupy a resting position and an active position, wherein in the resting position, the actuator assembly is disengaged from the inner carrier, and in the active position, the actuator assembly is engaged with the inner carrier to oppose the bias of the spring and retain the inner carrier in the first position. 2. The power distribution assembly of claim 1, wherein the spring is disposed about the crankshaft. 3. The power distribution assembly of claim 2, wherein in the resting position, the actuator assembly enables the spring to retain the inner carrier in the second position. 4. The power distribution assembly of claim 1, wherein the outer carrier and the one or more clutch plates are configured to rotate in unison with the crankshaft. 5. The power distribution assembly of claim 4, wherein the rotatable shaft is configured to rotate in unison with the inner carrier. 6. The power distribution assembly of claim 5, wherein the inner carrier is configured to rotate in unison with the crankshaft when occupying the first position. 7. The power distribution assembly of claim 6, wherein the inner carrier is configured to arrest rotation of the rotatable shaft when occupying the second position. 8. The power distribution assembly of claim 1, wherein the actuator assembly comprises a rotatable actuator handle, an actuator shaft affixed to the actuator handle, and an actuator fork affixed to the actuator shaft, wherein rotation of the actuator handle induces rotation of the actuator shaft, which induces rotation of the actuator fork, and wherein rotation of the actuator fork applies a counter force against the inner carrier. 9. The power distribution assembly of claim 8, wherein the applied counter force opposes the bias of the spring and motivates the inner carrier toward the first position. 10. The power distribution assembly of claim 9, wherein the actuator assembly further comprises a thrust bearing disposed between the actuator fork and the inner carrier such that the counter force is applied against the inner carrier at least via the thrust bearing. 11. The power distribution assembly of claim 10, wherein when the actuator assembly occupies the active position, the thrust bearing directly contacts the inner carrier. 12. The power distribution assembly of claim 10, wherein the thrust bearing is disposed about the rotatable shaft. 13. The power distribution assembly of claim 1, further comprising a transmission gear splined to the crankshaft above the outer carrier. 14. The power distribution assembly of claim 1, wherein the inner carrier comprises a flange disposed between the one or more clutch plates and the one or more brake plates. 15. The power distribution assembly of claim 14, wherein when the inner carrier occupies the first position, at least one of the one or more clutch plates applies a torque to the flange of the inner carrier and the inner carrier carries the torque toward the rotatable shaft. 16. A power distribution assembly, comprising: a prime mover disposed in a housing;a first rotatable shaft disposed in the housing, wherein the first rotatable shaft is an engine crankshaft driven by the prime mover;a clutch mechanism disposed in the housing, the clutch mechanism comprising: one or more clutch plates configured to be driven by the first rotatable shaft;a rotatable carrier configured to occupy a first position where the carrier is engaged with the one or more clutch plates and a second position where the carrier is disengaged from the one or more clutch plates;a second rotatable shaft driven by the carrier;a spring biasing the carrier away from the first position and toward the second position;an actuator assembly configured to occupy a resting position and an active position, wherein the actuator assembly comprises a rotatable actuator handle, an actuator shaft affixed to the actuator handle, and an actuator fork affixed to the actuator shaft, wherein rotation of the actuator handle induces rotation of the actuator shaft, which induces rotation of the actuator fork, and wherein rotation of the actuator fork applies a counter force against the carrier, which opposes the bias of the spring and motivates the carrier toward the first position; andwherein in the resting position, the actuator assembly is disengaged from the carrier, and in the active position, the actuator assembly is engaged with the carrier to oppose the bias of the spring. 17. The power distribution assembly of claim 16, wherein in the active position, the actuator assembly causes the carrier to occupy the first position, and in the resting position, the actuator assembly enables the spring to retain the carrier in the second position. 18. The power distribution assembly of claim 16, wherein the actuator handle rotates in a first plane, the actuator shaft rotates in a second plane, and the actuator fork rotates in a third plane, the first plane, the second plane, and the third plane being parallel. 19. A power distribution assembly comprising: an engine disposed in a housing;a crankshaft driven by the engine and disposed in the housing;a clutch mechanism disposed in the housing, the clutch mechanism comprising: a rotatable outer carrier configured to be driven by the crankshaft;one or more clutch plates secured to the outer carrier such that the one or more clutch plates are configured to be driven by the crankshaft;one or more brake plates secured to the housing;a rotatable inner carrier configured to occupy a first position where the inner carrier is engaged with the one or more clutch plates and a second position where the inner carrier is engaged with the one or more brake plates;a spring biasing the inner carrier away from the first position and toward the second position, the spring being placed to be disposed about the crankshaft;a rotatable shaft driven by the inner carrier; andan actuator assembly having a first end disposed inside the housing and a second end disposed external to the housing, the actuator assembly configured to occupy a resting position and an active position, wherein in the resting position, the actuator assembly is disengaged from the inner carrier, and in the active position, the actuator assembly is engaged with the inner carrier to oppose the bias of the spring and retain the inner carrier in the first position.
