Some models require installation of harness clamp. If your unit does 

not have a clamp follow these directions.

1.  Remove shield and gear housing as an assembly.

 

a.  Loosen two (2) screws (M) that clamp the gear housing to the  

shaft.

 

b.  Remove locating screw (N) at the top of the gear housing.

 

c.  Pull shield and gear housing assembly from the  

 

drive shaft assembly.

Prevent the flexible drive cable from sliding from the drive shaft 

housing. If cable does slide free, clean dirt from cable and re-lubri-

cate with lithium based grease prior to re-assembly.

2.  Remove front handle.

 

a.  Remove screws and nuts and back plate from  

 

handle.

 

b.  Remove handle.

3.  Install clamp.

 

a.  Slightly spread clamp and slide up drive shaft.

 

b.  Do not tighten clamp at this time.

5.  Install Blade (I) on upper plate pilot. Blades must be installed so 

that rotation arrow on blade faces gear case. Secure blade with 

Lower fixing plate (J), and 10 mm nut (K). Turn nut counter-clock-

wise on PTO shaft to tighten. 

6.  Align hole in upper plate with notch in gear housing, and insert 

Locking Tool (A) to prevent splined shaft from turning.  Arrow on 

gear housing points to notch.  Tighten 10 mm nut securely.

7.  Insert split pin (L) in hole in PTO shaft, and bend pin legs around 

shaft counterclockwise to retain 10 mm nut.

Never reuse a split pin - install a new split pin each time a blade is 

installed or replaced.

 

8.  Remove locking tool.
