Which Kress Replacement Blade Kit Do I Need? Complete Compatibility Guide (2026)

If you own a Kress robotic lawn mower, one of the first maintenance questions you'll eventually ask is:

"Which replacement blade kit fits my mower?"

Kress currently offers two genuine OEM replacement blade kits—KA0017 and KA0018. While they may look similar, they are designed for different robotic mower models and cutting systems.

Choosing the correct blade kit ensures your mower continues delivering clean, precise cuts while protecting the cutting disc and maintaining factory performance.

In this guide, we'll explain the differences between the two blade kits, show you exactly which one fits your mower, discuss how often blades should be replaced, and answer the most common questions Kress owners ask.

KA0017 vs. KA0018: What's the Difference?

Kress introduced an updated cutting disc and blade mounting system as its robotic mower lineup expanded. Because of these engineering improvements, newer robotic mowers require a different blade and screw combination than the original Mission Series models.

Although the blades appear very similar, KA0017 and KA0018 are not interchangeable.

The easiest way to determine which blade kit you need is by your mower model.

Why Use Genuine Kress Replacement Blades?

Your robotic mower may cut grass for several hours every day, often making hundreds of thousands of cuts throughout the mowing season.

Using genuine OEM Kress blades helps maintain:

  • Cleaner grass cuts

  • Healthier turf

  • Longer battery runtime

  • Better mowing performance

  • Reduced stress on the cutting system

  • Proper blade balance

  • Factory cutting quality

While aftermarket blades are widely available, they often vary in hardness, thickness, balance, and manufacturing quality. Genuine Kress blades are engineered specifically for your mower's cutting system.

How Often Should Robotic Mower Blades Be Replaced?

There isn't one universal replacement schedule because every lawn is different.

Blade life depends on factors including:

  • Lawn size

  • Mowing schedule

  • Grass species

  • Soil conditions

  • Sand

  • Twigs

  • Small rocks

  • Pine cones

  • Leaves and debris

As a general rule, inspect your blades regularly and replace them whenever they become dull, chipped, bent, or damaged.

For commercial properties and golf courses where mowers operate daily, blade replacement may be needed more frequently to maintain the highest quality cut.

Signs Your Blades Need Replacing

Watch for these common symptoms:

  • Torn or ragged grass tips

  • Brown grass after mowing

  • Uneven cutting quality

  • Bent blades

  • Chipped blades

  • Excessive wear

  • Reduced mowing efficiency

  • Increased battery consumption

Replacing dull blades is one of the simplest ways to keep your robotic mower operating at peak performance.
