GARDENA

If your robotic lawnmower slips on wet grass, spins its wheels on the spot or leaves uncut strips on a slope, the cause usually lies with the wheels’ grip rather than the operating schedule. Carefully selected Gardena spare parts from this category improve the wheels’ contact with the ground and stabilise the mower’s movement. Although the section name covers parts for lawnmowers and trimmers, the items shown here are designed for Gardena robotic mowers.

What Gardena spare parts can you find in this category?

This section contains six items belonging to two types of components responsible for the robotic mower’s traction: spikes and spiked wheels. The entire range is made from the same material: 3 mm thick stainless steel. These parts are compatible with three model families: Live and Sileno City, Minimo, and the R38Li, R40Li, R50Li, R70Li and R80Li models. It is this compatibility with the relevant series that ensures correct fitting without the need for modifications.

What should you look for when choosing studs or wheels?

Spikes are a good choice when the wheels are mechanically sound, but the robot loses traction mainly after rain, on compacted turf or when starting off uphill. Wheels with spikes are worth considering when wear affects the entire drive component or when you want to immediately improve driving stability. In practice, the choice is simplified by four criteria:

• exact compatibility with the model range
• surface type, from soft ground to damp grass
• extent of wear, i.e. whether the problem relates only to traction or also to a worn wheel
• material and stiffness, as 3 mm-thick stainless steel withstands loads better than thinner components

The price difference between the spikes themselves and complete wheels stems mainly from the scope of replacement. This is important when planning maintenance. In a small, level garden, improving traction is usually sufficient. Where there are frequent turns, ruts and longer inclines, it is wiser to consider complete wheels.

Why do Gardena parts wear out and how can you check compatibility?

Traction components wear out due to abrasion, the presence of sand, wet grass and repeated turning on the spot. Genuine Gardena spare parts are selected based on compatibility with a specific model and factory specifications, but a well-made replacement can work just as effectively if it has the correct geometry, is made from the right material and is the correct thickness. The advantage of parts that meet the specifications lies in predictable fitting, the absence of play and even power transmission, whilst a thickness of 3 mm helps maintain rigidity under load. Before making a choice, it is therefore worth starting by identifying the robot’s model and only then deciding whether spikes or complete wheels would be better.

FAQ

1. How can you tell if mowing problems are caused by a lack of wheel grip?

Slipping on wet grass, spinning on the spot and uncut strips on slopes are typical symptoms mentioned in the article. If the wheels look mechanically sound, the problem is most likely down to traction.

2. Is it safe to use aftermarket parts instead of original Gardena parts?

Yes — a well-made replacement part can work just as effectively, provided it has the correct geometry, material and thickness. Original parts, on the other hand, ensure predictable fitting and no play.

3. Why are the thickness and material of the spikes and wheels important?

The material and thickness affect rigidity and wear resistance. 3 mm thick stainless steel withstands loads and sand better, which translates into a longer service life and a more stable ride for the robot.
