Why is my Jacobsen AR-522 Lawn Mower step cutting?
- J
  Joseph AriasSep 10, 2025
  Step cutting in your Jacobsen Lawn Mower, where grass is cut taller on one side, can occur due to several reasons. It might be caused by: * Uneven height-of-cut settings between cutting units. * Worn roller bearings or deck caster wheels. * Restricted cutting unit movement. * Variations in turf density. * Uneven machine ride height from side to side. * Uneven cutting unit height from side to side. To resolve this, check and adjust the height-of-cut, replace worn bearings or wheels, remove any restrictions to the cutting unit's movement, change your mowing direction, ensure proper tire inflation, and adjust for even mower weight distribution.

  A Jacobsen Lawn Mower engine that's hard to start or runs poorly may be due to several reasons. Check if the fuel level is low or if the fuel or fuel filter is dirty; if so, fill with fresh fuel, change the fuel filter, and bleed the fuel lines. Also, inspect and replace the air filter if it's dirty. For issues related to the injectors or fuel pump, or if you suspect a more general engine problem, consult the Engine Manual.

  If your Jacobsen Lawn Mower engine suddenly stops, the fuel tank may be empty; in this case, fill it with fresh fuel and bleed the fuel lines. Another reason could be that the interlocks were not set before you left the operator’s seat. Make sure to engage the parking brake and set the mow switch to OFF before leaving the seat.
