One of the most important aspects of keeping this mower in peak condition is knowing its exact oil capacity and following a proper maintenance routine.
Gravely ZT HD 60 Oil Capacity
The Gravely ZT HD 60 with a Kawasaki FR730V engine holds 2.1 quarts (2.0 liters) of oil with a filter change, and up to 2.2 quarts total after topping off. Gravely recommends using SAE 10W-40 oil for most conditions, with 5W-20 for cold climates and 20W-50 for hot climates. The first oil change should be done after 8 hours of use, followed by every 100 hours or annually, with the oil filter replaced every 200 hours.

Why the Correct Capacity Matters
Using the correct oil capacity is essential to protect the engine from damage.
- Underfilling may result in inadequate lubrication, overheating, and premature wear.
- Overfilling can cause excess pressure, foaming, and leaks around seals.
By keeping the oil level at the correct range, you ensure the FR730V engine operates smoothly and efficiently throughout the mowing season.

Recommended Oil Viscosity
The oil viscosity you choose should match your local climate and mowing conditions.
- SAE 10W-40 – Recommended for most normal operating conditions.
- SAE 5W-20 – Best for very cold weather conditions.
- SAE 20W-50 – Ideal for extremely hot temperatures above 104°F (40°C).
- Synthetic blends such as 0W-40, 5W-40, or 15W-50 are popular choices for year-round use, as they provide strong protection across a wide temperature range.
Using high-quality oil that meets or exceeds API service classifications ensures maximum engine life.
