Replacement of the blades is necessary when the operator notices increase of power absorption
during tilling, or when the blade dimension is significantly reduced compared to the original.
The use of the machine with blades in bad condition compromises the quality of work.
Before perform replacement of the blades:
 idle tractor engine, set the parking brake, disengage tractor PTO, and wait for all moving parts to
come to a complete stop;
 place the tiller slightly lifted from the ground on safety blocks or mechanical stands;
 lock the control lever of the hydraulic lift of the tractor;
 turn off the tractor and remove the key.
To perform the replacement of blades:
 remove the two bolts and washers clamping the blade to the rotor flange, then remove the blade;
 position the new blade exactly instead of the worn blade, then tighten the bolts, referring to the
tightening table of this manual for proper torque values. Be sure to install the blade with cutting
edge in front of the direction of rotation;
 repeat the same procedure for all the other blades.
At the end of the replacement, make sure the blades have the right helical arrangement, as shown
in the figure:
Periodically check the tightness of screws and nuts, and tighten if necessary.
IMPORTANT
Remove and install one blade at a time to ensure blades are correctly oriented when installed.
Replace worn blades only with original parts.
CAUTION
Worn tines may be very sharp!
