What to do if my Ferris FW15 engine will not turn over or start?

  Elizabeth WaltersAug 21, 2025
  If your Ferris Lawn Mower engine won't turn over or start, several factors could be at play. First, check if you are out of fuel; if the engine is hot, allow it to cool before refilling the tank. If the engine is flooded, move the choke control to the closed position. Other potential issues include a faulty, fouled, or incorrectly gapped spark plug, which should be cleaned, gapped, or replaced. Water or old fuel in the tank can also prevent starting, so drain the tank and replace with fresh fuel.

  If your Ferris Lawn Mower is difficult to drive or handles poorly, it could be due to improper tire inflation. Check the specifications for proper tire inflation and adjust the tire pressures accordingly. Another cause could be bent or binding motion control linkage rods. Inspect these rods and repair or replace them as necessary.

What causes excessive mower deck vibration in my Ferris Lawn Mower?
- D
  Dennis HawkinsAug 25, 2025
  Excessive vibration in your Ferris Lawn Mower deck can stem from several issues. Start by checking if the blade mounting bolts are loose and tighten them to 50 - 60 ft. lbs. (68 - 81 N.m.). Also, inspect the mower blades, arbors, and pulleys for any bending and replace if necessary. Ensure the mower blades are balanced after sharpening, and verify the belt is installed correctly. Reinstall the belt if needed.

Why does my Ferris FW15 engine stall easily with the mower deck engaged?
- M
  Michael RileyAug 23, 2025
  If your Ferris Lawn Mower engine stalls easily when the mower deck is engaged, it could be due to several reasons. Ensure the engine speed is set to full throttle. If the ground speed is too fast, decrease it. Also, check if the cutting height is set too low; if so, cut tall grass at the maximum cutting height during the first pass, then at the desired height for the second pass. Finally, make sure the discharge chute isn't jamming with cut grass; cut the grass with the discharge pointing towards the previously cut area.
