The Model 621 Articulator utilizes six individual 21” high-lift blades, with each of the three
articulating decks housing two blades.
NEVER go near, or expose yourself or others in any way to the blades while the engine is
running!
ALWAYS disengage the blades, turn off the tractor, remove the key, and set the parking
brake before attempting to inspect, adjust, change or perform any other maintenance to
the blades!
Keep all personnel clear of all controls while inspecting, adjusting, changing, or perform-
ing maintenance to the blades!
Inspect all blades for proper installation, orientation, tightness, sharpness, and overall
condition. Be sure the lift fins are oriented to the top of the blades. Verify that the mount
bolts are secure, the blades are sharp, and free of any nicks, cracks, or bends. Always
replace any damaged, dull, or missing blades before operating the Articulator. The rec-
ommended torque value for the blade bolts is
75 ft./lbs

tions. Contact your Lastec dealer for further information about optional blades available.
