Auxiliary lift system

The auxiliary lift system transfers the weight of the cutting unit
pivot wheel to the machine's front wheel.
The effect of the auxiliary lift system can be adjusted by
moving the gas spring up or down.
Maximum effect is obtained when the gas spring is placed in
the top hole.
No effect is obtained in the slot at the bottom.
When using the cutting unit, the gas spring must be mounted
in the top hole.
