Description
Sunseeker is younger on the German market than Husqvarna or Gardena—accordingly, spare parts are scarce in retail. If you’re looking for a new mowing disc for your V3 or X3, you often only have the option of going through the manufacturer with long waiting times. This disc is made in-house, with seven or nine pre-assembled stainless steel blades, shipped from the EU.
Why balancing matters for wide mowing decks
V3 and X3 work with a comparatively wide cutting unit. This brings speed to the area, but also makes the system more sensitive to unevenly distributed weight: the farther out a mass is positioned, the more strongly it affects rotational speed.
That’s why we manufacture the discs as a matched set and supply them pre-fitted. What matters during assembly is only the even tightening of the screws.
Practical consequence for operation: never replace blades individually. A fresh cutting edge next to worn ones weighs differently—and exactly this difference is transferred to the suspension.

Questions about Sunseeker replacement parts
Because the brand is still young in this country, most questions revolve around availability and fit:
Replacement on the Sunseeker
- Switch the device off and remove it from the charging station.
- Put on gloves and lay the robot on its side.
- Clear the mowing area of grass clippings so the disc sits flat.
- Loosen the old disc, fit the new one, and tighten the screws crosswise.
- After that, rotate it by hand and tap each blade— it must run freely.
Rotating it by hand is the most important step for wide mowing decks. If the disc rubs somewhere or a blade gets stuck, you’ll notice it here—not only after the first mowing run.

7 or 9 blades
For the V3 and X3, we offer two configurations. Both are mounted on the same attachment—the difference is how often a blade of grass is captured along the same path.
7 blades – for normal operation
The balanced choice for lawns that the robot travels over several times per week. Seven cutting edges deliver a clean result and distribute the load so that each individual edge retains enough material.
Where the growth is stronger or more collects between mowing passes, this is the more robust option.
9 blades – the finest cutting pattern
Nine cutting edges capture the grass blade more often on every pass. On a short-kept lawn with daily operation, this results in a particularly even look—especially noticeable with the wide cutting paths of these machines.
During longer mowing breaks, the advantage turns around: the same amount of work is spread over more edges, which dull faster. Then the 7-blade setup remains the more durable solution.
When a new set makes sense
Buy blades individually
Because with Sunseeker the entire set is always replaced and spare parts are difficult to get locally, it’s especially worth keeping a supply. The 60-blade replacement set including screws covers many replacements— and it’s in the shed when you need it.
