How to troubleshoot a Gravely Lawn Mower when the engine will not start?
The Gravely Lawn Mower engine won't start if the speed control lever isn't in neutral and the PTO switch isn't in the Off position. Also, make sure you have enough fuel and that it's clean. If the air filter is clogged, clean or replace it. For spark plug issues or safety interlock problems, consult the Engine Manual or your Dealer.
What to do if my Gravely Pro 150 Lawn Mower will not move or mow?
If your Gravely Lawn Mower won't move or mow when the engine is running, the transmission or mower belt might be broken, worn, or off the pulleys. Check these belts for wear, damage, and correct positioning. Replace them if needed, referring to the Service and Adjustments section for guidance.
Why won't my Gravely Pro 150 move on an incline?
If your Gravely Lawn Mower won't move when operated on an incline, check the steering and brake linkage for any debris or damage, and repair if necessary. Also, worn or damaged traction belts could be the cause, so inspect them and replace if needed. If the transmission shaft pulley is excessively worn, it should be replaced. For adjustments, see Service and Adjustments. For pulley replacement or linkage repair, see your Dealer.
What to do if my Gravely Pro 150 Lawn Mower will not crank?
If your Gravely Lawn Mower will not crank, the suggested solution is to charge the battery or replace it.
What causes changes in sound or vibrations in my Gravely Pro 150 Lawn Mower?
Changes in the sound or vibrations of your Gravely Lawn Mower can be due to loose or missing fasteners, so check all fasteners and replace them if necessary. Also, this can be caused by a mower blade problem, so refer to the mower Owner/Operator Manual.
