John Deere GM1072E Lawn Mower User Manual


 
Belt tension adjustment
The mower has an automatic belt tensioner. The tension is created by a spring
connecting a tensioner pulley to a fixed hitch plate with 3 positions (see fig. 14). Upon
delivery, the spring is located in the first position. When the belt stretches after use,
adjust the tension by relocating the spring in the other two holes. If the belt has
stretched to the point that the belt is not tight enough even in the last hole, then it is
necessary to replace the belt.
4.05 - Belt Replacement
If the belt has been stretched or damaged to the point where the proper tension cannot
be obtained it must be changed.
