ION

17. TRANSPORT POSITION-Head Attached

The machine is transported in line to the rear of the tractor with a minimum of 11-1/4” clearance between the
tension link and the rear cross member of the tractor cab. 

18. TRANSPORT POSITION-Head Removal

With the flail head removed the arms are fully folded but the lift ram remains retracted. If the lift ram is extended
the weight of the arms will cause the balance of the machine to go over center causing the tension link to crash
into the rear cross member of the tractors cab. 

During transport the 'SLEW’ mode must ALWAYS be selected on the control assembly.
