Officially, there has only ever been one Technic combine. The
other is actually an alternate model but is so good that it stands up
to the other in every way. These are both very large models which
both have the accurate appearance of real combines, albeit of very
different ages. Feature sets are very similar. Both have a
corn head with rotating threshers driven from the wheels. Both
can raise or lower the head and deploy a side chute. One does
with pneumatics and the other with gear systems.
Tough to pick a favorite here. You better buy both of them.
