A floor finish applicator including a cart having wheels and a body member constructed and arranged to receive a source of floor finish. The floor finish applicator also includes a pump coupled to the cart and operable to deliver floor finish to a floor, a floor finish feed conduit in fluid communication between the pump and a container supporting floor finish, and a transmission assembly coupled to the cart. The floor finish feed conduit supplies floor finish to the pump. The transmission assembly includes an axle coupled to and driven by a wheel of the cart, a drive gear connected to the axle, a drive shaft having a driven gear for engaging the drive gear and driving the pump, and a hand-actuated spring-loaded clutch for selective engagement of the pump and the drive shaft with the axle.

The floor finish applicator of claim 1, wherein the drive gear includes a one-way roller clutch. 3. The floor finish applicator of claim 1, wherein the driven gear is a bevel gear. 4. The floor finish applicator of claim 1, wherein the drive shaft includes a first shaft with the driven gear and a second shaft, the first and second shafts interconnected by a pin and slot arrangement. 5. The floor finish applicator of claim 1, further wherein said hand actuator is a user-operable bail coupled to the clutch. 6. The floor finish applicator of claim 5, wherein the bail is located on a user-operable handle of the cart located remotely from the clutch. 7. The floor finish applicator of claim 1, further comprising a user-actuatable cable coupled to and extending from the pivotal bar member to the hand actuator which is at a location remote from the clutch. 8. A floor finish applicator comprising: a cart including a body member adapted to support a reservoir of floor finish;a handle coupled to the body;a pair of wheels coupled to the body member and at least partially defining a pivot point of the body when force is applied to the handle;a pump coupled to the cart and operable to deliver floor finish to a floor;a floor finish feed conduit in fluid communication between the pump and a container adapted to hold floor finish, the floor finish feed conduit configured to supply floor finish to the pump; anda transmission assembly coupled to the cart and including a first shaft rotatably coupled to the pump to drive the pump via rotation of the first shaft,a second shaft coupled to and driven by at least one of the wheels, anda hand-actuated clutch drivably coupling the first shaft and the second shaft to each other, wherein the hand-actuated clutch includes a thrust washer mounted on the first shaft and a pivotal bar member for engaging the thrust washer and being pivotally mounted on one end and coupled to a hand actuator on the other end, the hand-actuated clutch having a first state in which the second shaft is drivably engaged with the first shaft to transfer rotational motion of the second shaft to rotational motion of the first shaft, and second state in which the second shaft is disengaged from the first shaft to permit rotation of the second shaft independently of the shaft, the hand-actuated clutch biased into the second state. 9. The floor finish applicator of claim 8, further wherein said hand actuator is a user-operable bail coupled to the clutch. 10. The floor finish applicator of claim 9, further comprising a cable coupling the user-operable bail and the clutch. 11. The floor finish applicator of claim 9, wherein the bail is located on a user-operable handle of the cart located remotely from the clutch. 12. The floor finish applicator of claim 8, wherein the first shaft and the second shaft are drivably coupled to each other in the first state via intermeshing gears. 13. The floor finish applicator of claim 12, wherein the first shaft and the second shaft are drivably coupled to each other by a first gear coupled to the first shaft that in a second gear coupled to the second shaft, and wherein the first gear is releasably engaged with the second gear. 14. The floor finish applicator of claim 8, further comprising a user-actuatable cable coupled to and extending from the pivotal bar member to the hand actuator which is at a location remote from the clutch. 15. The floor finish applicator of claim 8, further comprising a spring attached to the first shaft and biasing the clutch into the second state. 16. The floor finish applicator of claim 15, further comprising a user-actuatable cable coupled to and extending from the clutch to a location remote from the clutch, wherein actuation of the cable generates a force counter to the biasing force of the spring. 17. The floor finish applicator of claim 8, wherein the first shaft is slidably mounted for releasable engagement of the first shaft and the second shaft. 18. The floor finish applicator of claim 17, wherein the first shaft and the second shaft are drivably coupled in the first state of the clutch via at least one gear. 19. The floor finish applicator of claim 8, wherein rotation of the at least one wheel generates rotation of the first shaft in the first state, and wherein rotation of the wheel does not generate rotation of the first shaft in the second state.
