Yard Machines Lawn Mower Oil Capacity(For All Models)

Knowing the correct oil type and oil capacity is essential for reliable performance and long engine life. Yard Machines mowers use engines from Briggs & Stratton, Powermore (MTD), Honda, and Kohler, and each engine has a slightly different oil requirement.

Overfilling can cause smoking and poor performance, while underfilling may lead to overheating and engine wear.

This guide provides a complete Yard Machines lawn mower oil capacity chart broken down by mower type and model.

Guides for Yard Machines

1. Oil Type Recommendation: Most Yard Machines mowers perform best with SAE 10W-30 engine oil. For warm climates, SAE 30 can also be used in walk-behind mowers, while 5W-30 is ideal for cold weather. Always check your engine label or manual for specific viscosity guidelines.

2. Change Interval: New engines should have their oil changed after the first 5 hours of use (or first mowing season). After that, walk-behind mowers generally need oil changes every 25 hours, while riding mowers can go 50–100 hours depending on workload.

3. With vs. Without Filter: Riding mowers and tractors with oil filters typically hold more oil than push mowers without filters. Be sure to account for this difference during maintenance.

4. Check with Dipstick: Always confirm oil level with the dipstick after filling. Add oil gradually to avoid overfilling.

FAQs

How much oil for Yard Machine lawn mower?

Most Yard Machines walk-behind lawn mowers require 15–22 ounces (0.47–0.69 quarts) of oil depending on the engine size. Riding mowers and lawn tractors typically use 1.5–2.0 quarts of oil, with slightly more if an oil filter is installed. Always check your engine model and confirm with the dipstick after filling.

How much oil is needed for a lawn mower?

The amount of oil a lawn mower needs depends on its size and type. Walk-behind mowers usually hold between 15 and 22 ounces, while riding mowers use anywhere from 48 to 67 ounces (1.5–2.1 quarts). Zero-turn and V-twin models tend to require closer to the higher end of that range.

How much oil does a Yardworks 174cc lawn mower take?

A Yardworks 174cc lawn mower typically takes 18–20 ounces (about 0.56–0.63 quarts) of oil. Since this model uses a mid-sized engine, be careful not to overfill—add oil gradually and use the dipstick to confirm the proper level.

What kind of oil does a Yardman lawn mower use?

Yardman lawn mowers, like Yard Machines, are made by MTD and most commonly use SAE 10W-30 engine oil. In warmer climates, SAE 30 may be used for push mowers, while 5W-30 is recommended in colder conditions.

What oil does a Yard Force lawn mower take?

Yard Force lawn mowers generally use SAE 10W-30 oil, suitable for most operating temperatures. Some models may allow SAE 30 in warmer regions. For best performance, stick with a high-quality detergent oil designed for small 4-cycle engines and change it every 25 hours of use or once per season.
