12 – Hoes replacement 

 

The  hoes replacement  must be made disassembling the roller group and placing the machine on 
the back side so that the hoes are parallel to the ground. Place the machine on a stable and safe 
plane.  When mounting the new hoes, be sure that the clamping nut fits well in its seat (Fig. 8 Ref. 
B); It is necessary to use new nuts, bolts and washers each time the hoes  are replaced. N.B. Use 
always  original  steel  bolts.  In order  to  use  the  hoes  as much  as possible,  the machine has  on  the 
sides  two  extensions(Fig.  6  -  Ref.  B),  this  allows  to  work  even  if  the  hoes  are  worn  out,  the 
consumption must not exceed the 2/3 of the hoe itself.  
N.B.  For  low-powered  walking  tractors  (8-10HP)  check  that  the  PTO  height  from  the  ground  is  at 
least 28-30 cms. If the height is of 25-26 cms. it is necessary to replace the hoes with shorter ones in 
order that the machine is in-line with the walking tractor or tractor.

While replacing the hoes, wear protective gloves. If the maintenance is made on a raised 
plane,  always wear safety shoes. 

 
All the maintenance work must be made with the walking tractor or tractor off and the key off. 
 
If  the  tightening  of  the  hoes  screws  is 
made  with  pneumatic  screwdrivers, 
put  on    ear  protections  and  protective 
glasses.
