A tractor mounted front end loader with a swingable boom assembly carrying a bucket, there being an ejector assembly for the bucket. The boom arms are shortened to place the center of gravity of the bucket proximal to the front tires of the loader, to place the cutting edge of the bucket closer to the center line of the front axle of the tractor; to place the boom to bucket pivot proximal to the surface upon which the loader is working and the cutting edge of the bucket in a horizontal plane slightly below that of the boom to bucket pivot, as compared with a loader without a bucket ejector assembly, to the end that bucket capacity is increased, reach and dump height are increased, cycle time is reduced and greater breakout force can be developed inasmuch as the bucket can be dumped, by use of the ejector assembly, while in a horizontal position. The ejector assembly includes upper and lower swingable panels within the bucket, hinged together with means for sealing the hinge. Rollers are provided at the normally forwardmost edge of the lower panel, for engagement with the bucket, and a scraper is provided in front of the forwardmost edge of the lower panel for cleaning a pathway in front of the roller during operation of the ejector assembly by a pair of cylinder driven arms.
