4.5.13 Header Swivel Gearbox and Hitch Swivel Gearbox

There are multiple gearboxes on the rotary disc pull-type: the hitch swivel gearbox , and the header swivel gearbox. Both
the hitch and the header gearboxes consist of an upper and lower gearbox. The hitch swivel gearbox transfers power from
the tractor to the header swivel gearbox through multiple drivelines. The header swivel gearbox transfers power to the
cutterbar and the conditioner roll timing gearbox.
If either of the gearboxes requires repair, remove it and have it serviced at your MacDon Dealer.
IMPORTANT:
The header and hitch swivel gearboxes appear similar, but they are NOT the same and they are NOT interchangeable.
