The Hayter T424 Mower is a diesel engine powered self propelled machine with hydraulic systems for ground
drive, cutterhead drive, cutterhead lift and steering. The machine operates in four wheel drive at all times, how-
ever, the transmission system can be operated in both ‘work’ and ‘transport’ modes. These modes can be select-
ed by the operator. In order to optimise machine performance and reduce transmission system wear it is advis-
able to operate the machine in the appropriate mode. ‘Work’ signifies cutting operations and ‘Transport’ signi-
fies travelling between work sites. A differential lock function may be selected.
