Cutting efficiency and air flow
The efficiency of a rotary cutting unit is directly
related to the air flow within the deck.
Inspect and
clean out
periodically to
maintain air flow
The underside of the cutting deck should be
examined periodically. The air flow is significantly
affected if the deck is not cleaned out periodically.
Blade Removal and Installation
Impact gun -
blade removal
only!
Start bolt by
hand and
properly torque.
It is very important that the blade retainer nut/bolt be
properly tightened.
If the retainer is not tight enough, the blade may
loosen during operation. If the retainer is too tight,
thread damage may occur and compromise the
integrity of the fastener.
