Looking at the scene, it is was taken here in Queensland around 1964 where sugar cane is a major industry on the tropical coast .The harvester is a Massey Ferguson model 515 which is side mounted to the tractor and powered by a 24hp Wisconsin petrol engine. Output about 15 tons/hr in average conditions and was up to 40 tons per hour in good conditions. The bin on the trailer would vey likely be a small railway wagon carroed on rails on the trailer. Once the bin is full, it is transported to a railway siding where it is rolled onto the tracks and then taken to the sugar mill. There narrow gauge train transport systems are still in use today here. I found an almost identical photo in a Power Farming Technical Annual machinery guide except that the tractor was a standard MF65 - not the hi-clear version shown here. The cane has also been burnt to remove leaf matter, rodents and snakes! Today, most of the cane is harvested "green" or unburnt. This was the first cane harvester designed & built by MF here, being developed in 1958. If you follow this link, it covers the development of this harvester. http://www.engineersaustralia.org.au/si ... vester.pdf
A copy of the sales prochure of this harvester can be seen at http://www.farmphoto.com/thread.aspx?mid=841944
