Good sized tractor mounted PTO driven concrete mixer. Takes a good barrow and a half or more mix.
Has ram to tip, so you need spool valve on your tractor, I used this on an old International 674 - but it would fit on a more compact machine with cat 1 linkage.
Simple PTO drives a small diameter sprocket, and a chain reduces the drive to a larger sprocket on the drum.
Handy bit of gear - came from TRW engineering at Tavistock about 5 years ago for a specific job - not been used at all since.
Have book - BUYER COLLECTS PLEASE, can load with a small forklift on a pallet.
