I did some experimenting today while using the tractor on the airfield.
what I was told wasn't correct.
on the ford 5000 the start safety interlock is also only on the high - low gear lever.
there is no interlock on the 1-2-3-4-R gear lever.
... I wish people would confine themselves to facts when they tell me things.
what I'd like to know is what oil lubricants are called out for these tractors.
it is in the user manual but not in the servicing manual.
don't have a user manual.
