4.       Note:     It is possible to install the engine to mower   deck drive belt   CP/N

 

6111)  at  this  time; however,  our  engine  manufacturers  have suggested  that this  
belt  be installed  after  the  engine  has  been  fully  serviced  per  manufacturers'  
suggestions  and  allowed  to  operate  at   1/2  to 3/4  throttle settings  for  
approximately C3)  minutes.     This   will  place  the initial  start up  of   the  engine  
in a no load  situation  and  allow  complete  engine lubrication.

 

Adjustment:

 

1.       Install engine to mower deck drive belt (P/N 6111).

 

2.       Check and adjust tire pressures.

 

Front  19  to  21  psi;  Rear  a  to 12 psi.

 

Tires may have been over inflated for   shipping purposes.

 

3.       Place the mower on a level surface.     Using  the lift   handle, raise  the  mower deck  to  

a  height   which   will  allow  measurements  to  be  taken  from  the  surface to   the  tops  
of  the  two  outer   mower   deck  cutter   blades  CP/N  6321).

 

4.       Align  both  outer  mower  deck cutter  blades  to  obtain  a  side  to  side  measurement.     

Starting   with  the  left   blade  as  viewed  from  operator's  position, secure   
measurement   from  level  surface   to   the  bottom  of   the  cutter   blade  tip rotate   
blade   and  check  measurement   on   opposite   end   of   cutter   blade.     Tip to tip   
measurement   on   the   same   cutter   blade   should   not   vary more than   l/8th of an inch.     
Maintain measurement   taken   and verify against   the right   outer   cutter blade.     If   
adjustment   is   required, loosen or   tighten   the nuts on the   two rear   L—rods.

 

5.       Align both outer mower deck cutter bla

des   front   to rear as viewed from operator's   

position.     Measure from surface   to the   bottom of   the   cutter blade tip,   at   the 
rear   of   the mower   deck.     Using  the  nut   on  the  single 

front   L-rod,  loosen  or   

tighten   as  required   to  place   the  mower   deck  at   an 

attitude  of   approximately  

l/8th   of   an  inch  higher   in   the   rear   than  the 

front   of   the   deck.

 

£.       Recheck  belt   routing and  alignment,  start   engine,  burnish  in  electric   bl

ade

 

clutch   using   at   least   C5)  engagements   at   3/4  to   full   throttle   settings.     Each 
engagement   should  last   approximately  C5)  seconds.

 

Note:     The  completed  adjustment   places  the  mower   deck  in  an  attitude  or 
position   which   will  produce  a  quality  cut.     Ground   speed,  grass  

conditions, 

types   of   grass,   tire  pressures,   dull  or   bent   blades   and  loose   belts   are 

just   

some  of   the  factors   which   will  cause   poor   cut   quality.
