A tractor loader attachment system for efficiently attaching and removing a loader upon a tractor. The tractor loader attachment system generally includes a pivot bracket attached to a loader mounting pocket, an engaging member pivotally connected to the pivot bracket, an actuator attached to a first end of the engaging member and to the tractor frame, wherein movement of the actuator pivots the engaging member so that a hooked end of the engaging member engages or releases a shaft attached to the loader frame to selectively retain the loader frame attached to the tractor vehicle.

1. A tractor loader attachment system, comprising: a pivot bracket attached to a first mounting bracket, wherein said first mounting bracket is attached to a tractor frame of a tractor vehicle;an engaging member having a first end, a second end and a pivot portion between said first end and said second end, wherein said engaging member is pivotally connected to said pivot bracket via said pivot portion; andan actuator attached to said first end of said engaging member and to said tractor frame, wherein movement of said actuator pivots said engaging member into a release position or a catch position, wherein when said engaging member is in said catch position said second end engages an upper shaft disposed on top of a loader frame to prevent said loader frame from being removed from said first mounting bracket and wherein when said engaging member is in said release position said second end does not engage said shaft thereby allowing said loader frame to be removed from said first mounting bracket;including a control unit in communication with said actuator to control movement of said actuator, wherein said control unit is comprised of a valve unit fluidly connected to a pressurized hydraulic system of said tractor vehicle, wherein said valve unit is fluidly connected to said actuator, and wherein said actuator is comprised of a hydraulic cylinder. 2. The tractor loader attachment system of claim 1, wherein said first mounting bracket is comprised of a loader mounting pocket. 3. The tractor loader attachment system of claim 2, wherein said loader mounting pocket includes an upper slot, wherein said pivot bracket is attached to said loader mounting bracket with a fastener extending through said pivot bracket and said upper slot. 4. The tractor loader attachment system of claim 3, wherein said fastener is comprised of a threaded fastener and a threaded nut. 5. The tractor loader attachment system of claim 1, wherein said second end is comprised of a hooked end. 6. The tractor loader attachment system of claim 5, wherein said hooked end includes a cutout facing downwardly. 7. The tractor loader attachment system of claim 1, wherein said pivot bracket is comprised of a U-shaped structure defining a slot, wherein said engaging member pivotally extends within said slot. 8. The tractor loader attachment system of claim 1, wherein said actuator is comprised of a linear actuator. 9. A tractor loader attachment system, comprising: a tractor vehicle having a tractor frame;a loader locking guide attached to said tractor frame;a loader mounting pocket attached to said tractor frame;a loader unit having a loader frame and a shaft attached to an upper portion of said loader frame, wherein said loader frame includes a lower catch member to catchably engage said loader loading guide and wherein an inner end of said loader frame is positioned within a pocket of said loader mounting pocket;a pivot bracket attached to said loader mounting pocket;an engaging member having a first end, a second end and a pivot portion between said first end and said second end, wherein said engaging member is pivotally connected to said pivot bracket via said pivot portion; andan actuator attached to said first end of said engaging member and to said tractor frame, wherein a first movement of said actuator pivots said engaging member into a release position and a second movement of said actuator pivots said engaging member into a catch position, wherein when said engaging member is in said catch position said second end engages said shaft disposed on top of said loader frame to prevent said loader frame from being removed from said loader mounting pocket and wherein when said engaging member is in said release position said second end does not engage said shaft thereby allowing said loader frame to be removed from said loader mounting pocket; including a control unit in communication with said actuator to control movement of said actuator, wherein said control unit is comprised of a valve unit fluidly connected to a pressurized hydraulic system of said tractor vehicle, wherein said valve unit is fluidly connected to said actuator, and wherein said actuator is comprised of a hydraulic cylinder. 10. The tractor loader attachment system of claim 9, wherein said pivot bracket is comprised of a U-shaped structure defining a slot, wherein said engaging member pivotally extends within said slot. 11. The tractor loader attachment system of claim 9, wherein said actuator is comprised of a linear actuator. 12. The tractor loader attachment system of claim 9, wherein said pocket of said loader mounting pocket is formed to a shape of said inner end of said loader frame. 13. The tractor loader attachment system of claim 9, wherein said loader mounting pocket includes an upper slot, wherein said pivot bracket is attached to said loader mounting bracket with a fastener extending through said pivot bracket and said upper slot. 14. The tractor loader attachment system of claim 13, wherein said fastener is comprised of a threaded fastener and a threaded nut. 15. The tractor loader attachment system of claim 9, wherein said second end is comprised of a hooked end. 16. The tractor loader attachment system of claim 15, wherein said hooked end includes a cutout facing downwardly.
