1.  Raise the hitch arms (#4) and the hitch supports (#5) from the deck.  Remove the 

bolt holding on the top link (#6).  Line up the end holes on the hitch supports with 
the holes on the outside of the hitch arms where you just removed the bolt.  Bolt 
the hitch arms, hitch supports and top link together with the bolt you just removed 
using two flat washers and a lock nut. 
 

2.  Connect the PTO shaft to the gearbox.  A snap ring holds on the PTO shaft with 

a shear pin.  Make sure the PTO guard (#3) is bolted in place. 
 

3.  Re-check all the fasteners.  There should be free movement of all pieces held 

together by a bolt and lock nut. 

 

 
All cutters have the required holes for mounting the chain kit.  The use of this chain kit 
will help reduce the possibility of injury to persons or property by stopping many thrown 
objects.  
 
1. 

Bolt the front chain holder (#1) to the front of the cutter using 3/8” x 1" hex bolts, 
lock washers, flat washers and hex nuts. 

 
2. 

Use ¼” x 5 link chains (#8) at the front.  A chain is pushed through each slot from 
underneath and a 3/8" rod is threaded through the top link of each chain.  Hold 
rods in place using the cotter pins supplied.   See parts list for correct length of 
rods. 

 
3. 

Bolt the rear center (#3) and rear side (#4 & #5) chain holders to the rear of the 
cutter.  Use ¼” x 5 link chains (#8) along all rear edges.  Thread rods as in front 
using lengths as shown in parts list.
