1. If you do cutting on well-kept surfaces without terrain irregularities, the mower can be 

pushed  without  lifting  the  machine  front  and  with  the  support  plate  sliding  on  the 
stubble.  Be  prepared,  however,  that  the  forward  motion  will  not  be  ideally  even.  Any 
unexpected bump can swerve the mower from straight direction. 

2. If there are some bumps on the surface such as molehills or natural terrain irregularities, 

it  is  advised  to  slightly  lift  the  machine  front  by  mildly  pushing  down  on  handlebars 
handles while pushing the mower forward. 

 

5.6.3 Cutting procedure. 
 

Set  the  engine  on  maximum  speed,  let  the  mowing  disk  rotate  at  maximum  speed 

(see chapter 5.3) and get the machine into motion (see chapter 5.6.2) against the sward to be 
cut. Mown grass is thrown away by the mowing disk to the right side onto the apron, which 
forms a swath. 

 
If  the  stand  is  very  dense,  grown  through,  rotten  or  lodged,  the  machine  working 

width  must  be  reduced  accordingly  so  that  the  mowing  disk  rotations  are  not  being 
excessively reduced and the cutting quality impaired. 
 
5.6.4 Problems at cutting. 
 

Choking of the space under the lower casing with grass shows as follows: 
 

a) Engine markedly loosing speed but not stalling: stop the machine without delay while 

slightly  lifting  the  machine  front  (by  pushing  down  on  the  handlebar  handrails).  The 
space  under  the  lower  casing  will  do  itself  a  partial  clearance  of excessive grass.  Then 
drive the machine against the sward again (see chapter 5.6.2). 
 

,

Be very careful while driving with the machine backwards! 
 

b) Engine  loosing  speed  and  stalling:  release  the  control  bar  of  the  mowing  disk  drive 

clutch  on  handlebars,  lift  the  machine  front  (by  pushing  down  on  the  handlebars)  and 
drive a bit back. Clear the space under the lower casing and spread the cut grass across 
the ground. Start the engine, switch on the mowing disk drive (see chapter 5.3) and once 
again drive the machine against the grass stand (see chapter 5.6.2). 

 

,

The  engine  must  be  always  switched  off  when  clearing  the  space  under  the  lower 
casing! 
 

,

Tilt  the  machine  always  only  backwards  onto  the  handlebars.  Be  always  very 
careful  while  moving  in  the  space  under  the  lifted  machine!  Secure  the  machine 
against motion! 
 

,

Be  very  careful  while  cleaning  the  space  under  the  lower  casing.  Cutting  edges  of 
the blades are sharp. You should be wearing protective gloves or you can also use a 
suitable piece of branch etc.
