Seasonal: Sharpen/replace blades, fog engine for storage, check tire condition.

WARNING! Always refer to your specific model's manual for exact intervals.

Engine Service

Procedures for common engine maintenance and repair.

Oil Change: Run engine to warm oil. Drain via plug, refill with recommended SAE grade.
Air Filter: Replace paper element or clean foam pre-filter as needed.
Spark Plug: Gap to specification (typically .030"). Replace annually.
Carburetor Adjustment: Set idle and high-speed screws per engine manual.
Fuel System: Inspect fuel lines, replace filter annually, clean sediment cup.
Valve Clearance: Check and adjust intake/exhaust valves (refer to engine specs).

CAUTION! Engine components are hot after operation. Allow to cool.

Electrical System

Diagnosis and service of starting, charging, and safety interlock systems.

Component	Test Procedure	Specification
Battery	Load test with multimeter.	12.6V static, >9.6V under crank.
Starter	Check amp draw, inspect solenoid.	Draw within engine manufacturer specs.
Alternator/Charger	Check AC output at stator, DC voltage at battery with engine running.	13.5-14.5V DC at high RPM.
Safety Switches	Continuity test in engaged/disengaged positions (seat, PTO, brake).	Circuit open/closed as per switch logic.
Wiring Harness	Inspect for chafing, corrosion, loose connections.	Clean, tight, insulated connections.

Drive System

Service for hydrostatic transmissions and gear drives.

Hydrostatic Drive: Check fluid level, inspect cooling fins, test relief valves.
Belt Adjustment: Adjust idler pulley for proper deflection (typically 1/2").
Pulleys & Idlers: Inspect for wear, cracks, and smooth rotation.
Axles & Hubs: Check for play, lubricate as specified.
Brake Adjustment: Adjust linkage or caliper for proper stopping.

Tip: Always relieve hydraulic pressure before disconnecting lines.

Hydraulic System

For models equipped with hydraulic lift or attachments.

Fluid Type: Use manufacturer-recommended hydraulic fluid (e.g., ISO 46).
Filter Change: Replace spin-on filter during fluid change.
Pump: Check for noise, leaks, and proper pressure output.
Cylinders: Inspect rods for scoring, check seals for leaks.
Hoses & Fittings: Inspect for cracks, bulges, and secure connections.
Bleeding: Cycle system to remove air after service.

Troubleshooting Guide

Common problems and solutions.

Symptom	Possible Cause	Corrective Action
Engine won't start	Dead battery, faulty solenoid, bad spark plug, fuel issue, safety switch.	Check battery/connections, test spark, verify fuel flow, bypass switches for diagnosis.
Loss of power	Clogged air filter, old fuel, dirty carburetor, weak compression.	Replace filter, drain fuel, clean carburetor, perform compression test.
Poor cutting performance	Dull/bent blades, worn deck belt, low engine RPM.	Sharpen/balance blades, adjust/replace belt, check governor setting.
Hydrostatic drive weak/no movement	Low fluid, worn drive belt, internal pump wear, linkage out of adjustment.	Check fluid, inspect belt, test pump pressure, adjust control linkage.
Electrical failure	Blown fuse, corroded ground, faulty ignition switch.	Check all fuses, clean battery ground, test switch continuity.
