Product Information

Full details

The Scheppach MS173-51 is designed for homeowners with larger garden spaces up to 1600 m² who need a reliable, high-performance tool to manage expansive lawns. Its standout feature is the powerful 173cc 4-stroke engine paired with a self-propelled drive system, which significantly reduces physical fatigue during long mowing sessions. While it provides excellent cutting versatility and a generous grass collector, users should note that as a petrol-powered machine, it requires regular engine maintenance and careful handling compared to electric or battery-operated alternatives.

FAQs

What type of oil should I use for the MS173-51?

You should use high-quality 4-stroke lubrication oil designed for small garden machinery engines.

Is the grass collector easy to remove?

Yes, the 65L collector is designed for easy removal and emptying, then reattaches simply to the rear frame.

Can I use this mower on uneven or sloped terrain?

The self-propelled drive helps significantly on slopes, but always mow across slopes rather than up and down for safety and better control.

How often should I sharpen the blade?

The blade should be checked at the start of every season or if you notice that the grass tips are turning brown or frayed after cutting.

Does this mower require electricity?

No, this is a petrol-powered mower, so it is fully independent of electrical outlets.

What is the maximum lawn size recommended?

The Scheppach MS173-51 is recommended for lawns up to 1600 m².

Troubleshooting

Engine fails to start

Check that there is fresh petrol in the tank, the spark plug is securely connected, and the fuel valve is in the open position.

Mower is difficult to push even with drive engaged

Ensure the drive cable is properly tensioned and that there is no debris jammed in the rear wheel mechanism.

Uneven or poor cutting performance

Inspect the mower blade for damage or dullness; sharpen or replace if necessary and verify all four wheels are set to the same height position.

Pros and Cons

Pros

  • Powerful engine ideal for large lawns up to 1600 m²
  • Self-propelled mechanism reduces user fatigue
  • Versatile 3-in-1 system covers collection, mulching, and side discharge
  • Sturdy steel deck construction

Setup, Compatibility & Care

Setting up the MS173-51 involves attaching the handle assembly and ensuring the grass collection bag is properly mounted to the rear frame. Before the first start, you must add the appropriate 4-stroke lubrication oil and fresh petrol.

Care instructions are straightforward but critical for longevity:

  • Post-Use Cleaning: Use the deck wash port after every use to prevent grass build-up.
  • Engine Maintenance: Check oil levels regularly and perform seasonal oil changes as per the manufacturer's intervals to keep the 173cc engine running smoothly.
  • Storage: The foldable handle design is optimized for storage in smaller sheds or garages, reducing the overall footprint when the mower is not in use.
  • Blades: Periodically inspect the blade for sharpness and balance; replace if dull to ensure a clean, healthy cut.
