Understanding Gravely Zero Turn Mowers

A Quick Overview of Gravely

Gravely has built a reputation for strength, precision, and comfort. Their zero-turn mowers are popular with homeowners and professionals who need speed, maneuverability, and durability.

Key Features

• Superior maneuverability
• High-speed mowing
• Durable decks and frames
• Reliable engines designed for heavy use

Average Lifespan

A well-maintained Gravely zero-turn mower can last 10–15 years or roughly 3,500–4,500 hours of operation. Neglect maintenance and that lifespan can drop significantly.

Factors That Affect Longevity

• Frequency of use
• Terrain type
• Storage conditions
• Quality of maintenance

Why Maintenance Matters

Think of maintenance like caring for a car. Regular checks and simple tasks prevent small issues from turning into expensive repairs, and keep performance consistent.

Daily Maintenance Checklist

• Inspect tires, blades, and belts before mowing.
• Remove debris from the deck.
• Check for fluid leaks.
• Clean air vents after mowing.

Weekly Maintenance Routine

Checking Blades

Sharp blades make clean cuts and reduce engine strain. Inspect blades for nicks and balance.

Tire Pressure Checks

Keep tire pressure even to maintain mowing patterns and reduce uneven wear.

Monthly Maintenance Essentials

• Change oil and replace filters as recommended.
• Inspect battery for corrosion and secure connections.
• Check spark plugs and replace if needed.

Seasonal Maintenance Practices

Pre-Season Tune-Ups

• Grease fittings and pivot points.
• Check hydraulic fluid levels.
• Inspect belts and replace if worn.

End-of-Season Storage Tips

• Drain or stabilize fuel for long storage.
• Store in a dry, covered space.
• Disconnect the battery if storing long-term.

Blade Care and Sharpening

Sharpen blades every 25–30 hours of use, or replace them when worn. Dull blades tear grass and increase engine load.

Engine and Oil Maintenance

Clean oil keeps the engine cool and lubricated. Gravely typically recommends oil changes every 50 hours or annually—use high-quality SAE 30 or 10W-30 oil per the owner’s manual.

Fuel System Care

Use fresh fuel, avoid ethanol when possible, and add stabilizer before long storage to prevent gumming and carburetor issues.

Hydraulic System Maintenance

Hydraulic fluid powers the drive system. Check levels every 100 hours and replace hydraulic filters on schedule to avoid costly failures.

Deck and Belt Inspections

Keep the deck clean to prevent clumping and uneven cutting. Inspect belts for cracks or fraying and replace them before they fail.

Storage Tips to Extend Lifespan

• Store indoors, away from moisture and extreme temperatures.
• Use a breathable cover to keep dust out without trapping moisture.
• Keep fuel stabilized or emptied for long-term storage.

Professional Servicing

Annual professional service catches hidden issues early. A trained technician can fine-tune the engine, hydraulics, and electrical systems to keep your mower running reliably.

Conclusion

With simple daily checks, scheduled servicing, and proper storage, your Gravely zero-turn mower can be a dependable workhorse for many years. Regular care today saves time and money tomorrow.
