Header Swivel Gearbox and Hitch Swivel Gearbox
There are two gearboxes located on the rotary disc pull-type: the header swivel gearbox that transfers power to the rotary
disc pull-type cutterbar and conditioner roll timing gearbox, and the hitch swivel gearbox that transfers power from the
tractor to the header swivel gearbox. Both gearboxes consist of upper and lower gearboxes.
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.
