Abstract:
An agricultural vehicle includes a chassis (16), a lift arm (18) movably coupled to the chassis (16), a lift actuator (21) coupled to the lift arm (18), a header (14) coupled to the lift arm (18), and a controller (120) operably coupled to the lift actuator (21). The controller (120) is configured to: receive a header type signal corresponding to a header type of the header; define a lift height limit of the header based at least partially on the received header type signal, the lift height limit being a first height limit when a first header type signal is received or a second height limit when a second header type signal is received; and output a lift signal to the lift actuator (21) to vertically displace the header (14). Header vertical displacement is limited to the first height limit if the first header type signal is received or the second height limit if the second header type signal is received.
