Engine Repair & Service

Procedures for common engine services (e.g., Briggs & Stratton, Kohler).

  1. Spark Plug Replacement: Disconnect wire. Clean area. Remove old plug with socket. Gap new plug to specification (typically 0.030"). Install and tighten. Reconnect wire.
  2. Oil Change: Run engine to warm oil. Stop engine. Place drain pan under drain plug. Remove plug and drain oil. Replace plug. Refill with recommended SAE oil type and quantity.
  3. Air Filter Service: Remove cover. Replace paper filter or clean foam pre-filter with soapy water, dry, and re-oil lightly.
  4. Carburetor Cleaning: Disconnect fuel line. Remove carburetor. Disassemble and clean jets and float bowl with carburetor cleaner. Reassemble and reinstall.
  5. Fuel Filter Replacement: Clamp fuel line. Remove old in-line filter. Install new filter in correct direction (arrow toward carburetor).

Note: Refer to your specific engine model's manual for detailed torque specs and procedures.

Cutting Deck & Blade Service

Maintaining the cutting deck is crucial for a quality cut and mower longevity.

  1. Deck Removal: Lower deck to lowest setting. Disconnect deck drive belt from engine pulley. Remove retaining pins or bolts from deck hangers. Slide deck out from side.
  2. Blade Removal & Sharpening: Block blade from moving with a wooden wedge. Use correct socket to loosen bolt (typically reverse thread on some models). Sharpen blade evenly to maintain balance. Reinstall tightly.
  3. Deck Cleaning: Scrape off built-up grass and debris. Wash with water (avoid electrical components). Allow to dry completely.
  4. Deck Leveling: Place mower on level surface. Measure blade tip height from ground at all four corners. Adjust deck hanger linkages to achieve even height (typically 1/8" lower in front).
  5. Spindle Bearing Inspection: Spin each spindle pulley by hand. Listen/feel for grinding or roughness. Replace spindle assembly if bearings are worn.

Drive System & Transmission

Service for the drive belt, pulleys, and transmission (hydrostatic or gear).

CAUTION! Do not attempt to disassemble a sealed hydrostatic transmission. Service is typically limited to fluid changes and external linkage adjustments.

Electrical System
