This is heavy land. Fowler VF crawler tractor and an Allis Chalmers All-crop 60, an early combine harvester. It belonged to Victor Gray, New Hall Farm, Little Wigborough.

Bernard sent the photograph to Old Tractor Magazine, Sept 2005, with the caption:
Following a very wet harvest in 1958, an attempt was made to gather in the crop at New Hall Farm, Little Wigborough, in October using an Allis-Chalmers All-Crop 60 combine pulled by a Fowler VF crawler. Bernard tells us that it was so soft that a sledge had to be made to set the combine on. Note the spade, which was used to dig out the mud so that the starting handle could be inserted, and the fuse-holder laying on the left-hand track.

Date: October 1958
