This bale wrapper is suitable for use with tractors of a 0.9 minimum class and 
with power more than 30 KW equipped with a set of weights on the front axle. 

Its design is adapted for it’s connection with the Three Point Hitch of the tractor. 

       The Rotation frame shown as number 3 on the previous page placed on the lower frame shown as 
number 2 is connected aligned with the main frame shown as number 1 and is suspended on the three-
point  system of tractor. The  lower frame together with the rotation frame is secured against deflection by  a 
movable locking pin. Unloading  the bales from the bale  wrapper is possible after unlocking the pin and after 
the bale  wrapper is raised using  the Three Point Hitch of the tractor. It then unloads as the lower frame is 
tilted and the frame is rotated thus unloading the bales 

       The movement of the rotation frame and the rotation drums shown as by the number 5 on the previous 
page is carried out by the operation of the hydraulic motor, number  6 with overload valve wihich is operated 
by the hydraulic pump of tractor. This overload valve provides for smooth starting and stopping  of the  
machine. It also protects the  mechanical components of the drive from damage as a result of excessive 
load. The valve is factory-tuned to the engine and sealed. It should not be adjusted  unnecessarily.. 

       The drive from the engine is transmitted via a 5/8” (10B) chain on the chain wheel  of rotation frame.  
This provides for a rotation of  the  bale along the vertical  axis. Next,  power is transmitted  to  the  drums  
welded   via  a  conical  toothed  gear  and two chain transmissions.  This  provides  a  rotation  of  the  bale  
with  the  appropriate  ratio in the horizontal  axis,  this   causes   a  partial   overlapping  film  layers  and 
tightness of the layer. Roll of film is placed in the feeder (4).  The  film  is  stretched through the two tension 
rolls connected  with  toothed  gear,  which   ensures  tight adhesion of subsequent layers of film. 

The transmission ratio  is  chosen   so   as  to  ensure 
the  optimal  stretching  the film, however,  if 
necessary, stretching can be  adjusted  by   
tightening  the  nut pressure  of  film.  The  maximum  
extension/elongation  of   the   film   should   not 
exceed 70% of original length. That is,  segment  of  
film  with  the  length  of  10  cm after stretching, 
should not be longer than 17cm. should be applied a 
polyester film, stretch film,  self-adhesive  with  
stabilizer  of ultraviolet rays with a thickness of 0.025-
0.03mm  and the width of 500 or 750  mm.
