When you own a piece of Gravely equipment, whether it’s a robust zero-turn mower, a powerful tractor, or any of their other high-quality machinery, you understand the importance of keeping it in prime working order. Gravely has built a reputation for durability and performance, and that reputation is maintained by using the right parts and performing regular maintenance. This guide will walk you through the best ways to find replacement Gravely parts and shed some light on crucial aspects of their upkeep, such as the specific type of hydraulic oil you should be using.

Where to Find Genuine Gravely Replacement Parts
Finding the correct replacement parts for your Gravely machinery is crucial for ensuring it continues to operate efficiently and safely. Using aftermarket or incompatible parts can lead to premature wear, decreased performance, and potentially costly repairs down the line. Fortunately, Gravely provides several reliable avenues for obtaining genuine parts:
The most direct and often the best way to secure genuine Gravely parts is through an authorized Gravely dealer. These dealerships are specifically trained and equipped to handle Gravely products. They have access to the official Gravely parts catalogue, allowing them to identify and order the exact components you need for your specific model. Furthermore, their technicians are knowledgeable about Gravely equipment and can offer expert advice on installation or any other maintenance queries you might have. You can usually find your nearest dealer by visiting the official Gravely website and using their dealer locator tool. This is especially beneficial if you need a part that requires specialised fitting or if you’re unsure about the exact part number.
2. Official Gravely Online Store
Gravely also offers a convenient online store where you can purchase parts directly. This is an excellent option for common wear-and-tear items like filters, belts, blades, and spark plugs, or for those who are comfortable with DIY repairs. The online store often features detailed part diagrams and compatibility information, making it easier to find what you're looking for. Keep an eye out for special promotions, such as the Labor Day Sale mentioned, which can offer significant savings on online parts orders. These sales, like the current offer of 10% off plus free shipping on orders over $39.99, make stocking up on essential spares even more economical. Always ensure you have your Gravely model and serial number handy when ordering online to guarantee you receive the correct parts.
3. Reputable Online Parts Retailers
Beyond the official channels, several reputable online retailers specialise in outdoor power equipment parts. While some may offer genuine Gravely parts, others might carry high-quality aftermarket alternatives. If you opt for aftermarket parts, do thorough research to ensure they meet the quality standards expected for Gravely equipment. These retailers can sometimes be more competitive on price, but it’s essential to balance cost with quality and ensure the part is specifically compatible with your Gravely model.
What Information You’ll Need
Regardless of where you purchase your parts, having the following information ready will streamline the process:
- Gravely Model Number: This is essential for identifying the correct product line.
- Serial Number: This is critical for pinpointing the exact specifications and build date of your machine, as parts can vary even within the same model year.
- Part Number (if known): If you know the specific part number you need, it will speed up the ordering process significantly.
Understanding Gravely Hydraulic Oil
Proper lubrication and hydraulic function are vital for the smooth operation of many Gravely machines, particularly those with hydrostatic transmissions or hydraulic lift systems. Using the correct hydraulic oil is not just a recommendation; it’s a necessity for the longevity and performance of these complex systems.
What is Hydraulic Oil?
Hydraulic oil is a fluid used in hydraulic systems to transmit power. It acts as a lubricant, a coolant, and a means of transferring force. In Gravely equipment, hydraulic systems are often responsible for functions like powering the drive wheels (hydrostatic transmission), operating mower decks, and lifting attachments. The oil needs to be able to withstand pressure, maintain its viscosity across a range of temperatures, and protect components from wear and corrosion.
What Type of Hydraulic Oil Should You Use for Gravely?
Gravely typically specifies the use of a high-quality hydraulic/transmission fluid that meets specific industry standards. While the exact specification can vary slightly depending on the specific Gravely model and its intended use, many Gravely machines, especially those with hydrostatic transmissions, require a fluid that offers excellent anti-wear properties and consistent viscosity.

Important Considerations:
- Check Your Owner's Manual: This is the definitive source for the correct fluid specification for your particular Gravely machine. Always consult your owner's manual for the precise type and grade of hydraulic oil recommended.
- Hydrostatic Transmission Fluid (HST Fluid): Many Gravely zero-turn mowers and tractors equipped with hydrostatic transmissions require a specific type of HST fluid. These fluids are formulated to provide superior lubrication and protection for the internal components of hydrostatic systems.
- Viscosity: The viscosity grade (e.g., ISO VG 46) is important for ensuring the oil flows correctly through the system at different operating temperatures.
- Quality Matters: Opt for reputable brands that are known for producing high-quality hydraulic fluids. Using a generic or low-quality fluid can lead to increased wear, overheating, and reduced performance.
When to Change Hydraulic Oil
Regularly changing the hydraulic oil and filter (if applicable) is a key maintenance task. The service intervals will be detailed in your owner's manual. Generally, hydraulic oil should be changed:
- At the hours recommended in the owner's manual (e.g., every 100, 200, or 500 hours of operation).
- If the fluid appears discoloured, milky, or contains debris, indicating contamination or internal wear.
- After significant hydraulic system repairs.
General Maintenance Tips for Gravely Equipment
Beyond specific parts and fluids, consistent maintenance is the bedrock of keeping your Gravely equipment running smoothly for years. Here are some essential tips:
- Regular Cleaning: After each use, clean off grass clippings, dirt, and debris from the mower deck, engine, and chassis. This prevents rust and corrosion and allows for easier inspection.
- Inspect Belts and Blades: Check mower belts for wear, cracks, or fraying. Sharpen or replace mower blades as needed to ensure a clean cut and reduce strain on the engine.
- Check Tyre Pressures: Properly inflated tyres are important for cut quality and machine stability.
- Service Air Filters: A clogged air filter restricts airflow to the engine, reducing power and efficiency. Clean or replace them according to the manufacturer's schedule.
- Change Oil and Filter Regularly: Engine oil and oil filters should be changed at the recommended intervals to keep the engine lubricated and clean.
- Lubricate Moving Parts: Greasing zerks and lubricating pivot points ensures smooth operation and prevents premature wear.
