ABSTRACT:
A tractor includes a quick attach and dismount front end loader. The tractor is provided with rearwardly positioned side-mounting brackets which are adapted to lockingly engage the lower ends of uprights on the loader. A transversely extending mounting bracket is provided across the front end of the tractor for engagement with a cross frame member on the loader. A stand engages the cross frame member for supporting the loader independently of the tractor. Hydraulic cylinders on the loader for raising and lowering the boom are operated for mounting and dismounting the loader. When the front mounting bracket engages the cross frame member on the loader contraction of the power cylinder causes the loader to pivot clockwise about an axis through the cross frame thereby bringing the uprights on the loader into engagement with the side mounting brackets on the tractor. Extension of the power cylinders causes the loader to pivot counterclockwise for dismounting the loader. The loader is supported only at and by the front and two side brackets.
