ing a new wheel, screw the nut on and tighten by hand. Next, lower the wheels until 
they are touching the ground and tighten the nut to a torque of 100 Nm. 
 
Adjustment and lubrication of wheel bearings  
1.

 

Dismount the wheel (See”

Dismounting/Mounting Wheels

”

). 

2.

 

Remove the hubcap. 

3.

 

Take out the split cotter pin. 

4.

 

Tighten the castle nut 1/6 of a rotation until the hole is lined up with the axle. 
The hub must be turned just enough so that there is no drag on the bearing, yet 
there must not be so much slack in the hub that it jiggles from side to side. If 
there still is some slack in the hub, repeat the process.  

5.

 

Replace the split cotter pin. 

6.

 

Fill the hubcap ¾ full with lubricant and reinstall. 

For wheel mounting, see

General Information 

Avoid spilling oil on the ground. If this should happen, collect as much oil as possi-
ble and dispose of it properly.  
 
If the harrow is parked in an area of high humidity or dampness for a prolonged pe-
riod of time, apply oil or grease to the piston rods to prevent rust from developing. 
 
Cleaning and Inspection 
At  the  end  of  the  season,  clean  off  any  soil  or  plant  material  that  could  absorb 
moisture. This will facilitate later inspection of the machinery or any possible re-
pairs.
