Turn off the Dixon mower and allow it to cool off completely before making any adjustments.
Engage the Dixon's parking brake. Lower the cutting deck to its lowest setting with the control arm.
Remove any dirt or mulch that is clogged up in the drive chain on either rear side of the mower. Oil the chains on both sides and check the chain tension.
Adjust the drive chain tension if it is slack. To do this, loosen the tension bolt on the midway point of the drive chain on each side, push the spring-loaded roller upwards to increase tension, then tighten the tension bolt with the socket set. Repeat this step for the chain on the other side, as well, if it is loose.
