How to check and handle common problems with lawn mowers

There may be minor problems with the mower after a period of use, which can affect the efficiency of mowing and even potential hazards. So how do you check when the mower has these conditions?

  1. Severe vibration

There are several reasons why this can happen:

  • (1) The blade is bent or worn and loses its dynamic balance;
  • (2) the crankshaft is bent due to impact;
  • (3) The cutter is damaged, causing the blade to rotate relative to the crankshaft, causing an imbalance;
  • (4) Loose engine fixing screws, etc.;
  • (5) The engine base is damaged;
  • (6) The blade hits a hard object.
  1. The grass collection effect is not good
  • (1) The long-term use of the grass bag is not cleaned, resulting in uncleanness and airtightness resulting in poor grass collection;
  • (2) The grass drain is not cleaned for a long time, and the grass is blocked by the grass drain, resulting in poor grass discharge;
  • (3) The blade is excessively worn, and the blade does not have a grass collecting effect;
  • (4) The engine wears, the power loss is too large, and the blade rotation speed is low, resulting in poor grass collection effect;
  • (5) The grassland is not flat, resulting in poor grass drainage.
  1. The engine is not stable

The throttle is at the maximum position, the damper is open; the spark plug line is loose; water and dirt enter the fuel system; the air filter is dirty; the carburetor is improperly adjusted; the engine set screw is loose; the engine crankshaft is bent.
Remedy: Lower the throttle switch; press the spark plug outer line; clean the fuel tank, re-add fuel; clean the air filter or replace the filter; re-adjust the carburetor; check the engine fixing screw after the flame: correct the crankshaft or replace the new shaft.

  1. The engine can not be turned off

The throttle line is not properly installed on the engine; the throttle line is broken; the throttle is not sensitive; the flame line cannot be touched. Remedy: Reinstall the throttle line; replace the new throttle line; inject a small amount of oil into the throttle active position; check or replace the flame line.
