'10 ft. P.T.O. 'A.L.' Harvester: Oct 1939'
Tractor power-take-off drive shaft fitted to a 10 ft. 'A.L.' harvester. The power-drive is telescopic (male and female) to allow extension or reduction when cornering and for ground undulation variations. When the tractor power-take-off is used, 'grips' are no longer required on the main wheel.
