How to fix McCulloch M175H38RB that will not start?

  Travis RamirezAug 20, 2025
  If your McCulloch Lawn Mower won't start, several factors could be the cause. It might be out of fuel, so try filling the fuel tank. The engine may not be choked properly; refer to the 'TO START ENGINE' section in the Operation section. The engine could be flooded, so wait a few minutes before trying again. Other potential issues include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), water in the fuel (empty the tank and carburetor, refill with fresh gasoline, and replace the fuel filter), loose or damaged wiring (check all wiring), or engine valves that are out of adjustment (contact an authorized service center/department).

  Lynn SmithAug 25, 2025
  If your McCulloch Lawn Mower is hard to start, consider these possibilities: a dirty air filter (clean or replace it), a bad spark plug (replace it), a weak or dead battery (recharge or replace it), a dirty fuel filter (replace it), stale or dirty fuel (empty the fuel tank and refill with fresh, clean gas), loose or damaged wiring (check all wiring), or engine valves out of adjustment (contact an authorized service center/department).

  Connie BlackburnAug 27, 2025
  If your McCulloch Lawn Mower engine won't turn over, make sure the brake pedal is depressed. Also, ensure the attachment clutch is disengaged. Other possible causes include a weak or dead battery (recharge or replace it), a blown fuse (replace it), corroded battery terminals (clean them), loose or damaged wiring (check all wiring), a faulty ignition switch (check/replace it), a faulty solenoid or starter (check/replace them), or faulty operator presence switch(es) (contact a service center).

Why McCulloch Lawn Mower blades will not rotate?
- S
  Sarah MartinAug 28, 2025
  If your McCulloch Lawn Mower blades won't rotate, there might be an obstruction in the clutch mechanism (remove it). Alternatively, the mower drive belt could be worn or damaged (replace it). A frozen idler pulley (replace it) or a frozen blade mandrel (replace it) could also be the cause.

Why McCulloch Lawn Mower engine clicks but will not start?
- G
  Greg ColeAug 30, 2025
  If your McCulloch Lawn Mower engine clicks but won't start, the battery may be weak or dead, requiring a recharge or replacement. Corroded battery terminals could also be the issue, so clean them. Check for loose or damaged wiring. The solenoid or starter might be faulty, in which case you should check or replace them.

Why is my McCulloch M175H38RB cutting unevenly?
- J
  Joanne WrightSep 1, 2025
  If your McCulloch Lawn Mower provides a poor cut that is uneven, the blade might be worn, bent, or loose; replace the blade and tighten the blade bolt. The mower deck may not be level, so level it. There could be a buildup of grass, leaves, or trash under the mower, so clean the underside of the mower housing. A bent blade mandrel (replace it) or clogged mower deck vent holes from buildup of grass, leaves, and trash around mandrels (clean around mandrels to open vent holes) could also be the cause.

Why does my McCulloch M175H38RB Lawn Mower have excessive vibration?
- R
  Rhonda ScottSep 3, 2025
  If your McCulloch Lawn Mower has excessive vibration, the blade might be worn, bent, or loose; replace the blade and tighten the blade bolt. A bent blade mandrel (replace it) or loose/damaged part(s) (tighten loose part(s) and replace damaged parts) could also be the cause.

Why does my McCulloch M175H38RB Lawn Mower have poor grass discharge?
- J
  Jessica LoweSep 6, 2025
  If your McCulloch Lawn Mower exhibits poor grass discharge, ensure the engine speed isn't too slow by placing the throttle control in the 'FAST' position. Avoid moving too fast; shift to a slower speed. Wet grass can cause this issue, so allow the grass to dry before mowing. The mower deck might not be level, so level it. Check the tires for proper air pressure. Other possible causes include a worn, bent, or loose blade (replace and tighten), buildup of debris under the mower (clean underside of mower housing), a worn mower drive belt (replace it), improperly installed blades (reinstall with the sharp edge down), using improper blades (replace with listed blades), or clogged mower deck vent holes (clean around mandrels).

Why are the headlights not working on my McCulloch M175H38RB?
- R
  Renee GoldenSep 8, 2025
  If the headlight(s) on your McCulloch Lawn Mower are not working, first, ensure the switch is turned 'ON'. If not, the bulb(s) or lamp(s) may have burned out, requiring replacement. Other potential causes include a faulty light switch (check/replace it), loose or damaged wiring (check wiring and connections), or a blown fuse (replace it).

What causes McCulloch M175H38RB battery will not charge?
- E
  ericmcmahonSep 10, 2025
  If your McCulloch Lawn Mower battery will not charge, it could be due to bad battery cell(s), so replace the battery. Check and clean all connections to rule out poor cable connections. A faulty regulator (if so equipped) might be the problem, so replace the regulator. Alternatively, the alternator might be faulty, so replace the alternator.
