Murray riding mowers come in several sizes and power levels. When there is a problem with the engine, the discharge of the grass or the evenness of the mowing, several troubleshooting tips may help to find and solve the problem.
Check the seat switch and wiring harness
If the engine of a Murray riding mower stops while the blades are engaged, check your position on the seat. You must sit toward the back of the seat for the engine to remain on. If your seating position is correct, the seat switch may be faulty or have a bad connection. Make sure the seat switch is connected to the wiring harness. Replace either the switch or the harness if necessary.
Inspect the blades and underside of the mower
If the grass is not discharging properly from your riding mower, first make sure that you are not driving too fast. Also, if the grass is excessively tall or wet, it will not discharge properly. If neither of these issues is the problem, check the blades. If they are dull, sharpen them. If they are bent or damaged, they must be replaced. If the blades are fine, check for debris building up underneath the mower housing and clean it.
Take the tire pressure
If the mower is not cutting grass in a level, even manner, check the tire pressure. Inconsistent tire pressure can cause uneven cutting. Also, make sure the mower housing is properly leveled, and level it if necessary.
