Description
The SILENO series has been running in German gardens for many years – and is maintained instead of replaced. If you’re looking for spare parts, you want to keep using the device, not buy a new one. This disc fits SILENO life 750, 1000, 1250 and SILENO+ 1250, 1600 and comes with pre-assembled stainless steel blades.
Why swapping it on the SILENO is worth it
Gardena built the SILENO models to be robust. The drive and electronics can handle many seasons—what wears out first are the cutting disc and the disc it sits on.
That’s why so many replacement parts are searched for around these devices. A robot that works perfectly well except for a dull mowing deck is back to full performance with a new disc.
Our version replaces the original disc directly: just put it on, tighten it, done. No adapter, no adjustment, no tools beyond a screwdriver.

Questions about the SILENO mowing disc
With Gardena, the most common questions focus on two topics: distinguishing between the product lines and the cutting pattern at the edges.
Replacement on the SILENO
- Switch off the robot using the main switch and remove it from the charging station.
- Put on gloves and lay the device on its side.
- Remove accumulated grass felt—on older devices it is often dried and stuck in place.
- Loosen the old mowing disc, fit the new one, and tighten it evenly.
- Tap each blade: It must be able to rotate freely around its screw.
For devices that have a few years under their belt, it’s worth replacing the screws as well instead of reusing them. Worn-out heads make the next change unnecessarily difficult.

6, 7 or 9 blades on the SILENO
This is where the real lever for a better cutting pattern lies. More cutting blades mean more cuts on the same trip—exactly the improvement that many SILENO owners are looking for.
6 blades – factory configuration with center guard
The version that matches the original. The SILENO continues to work as usual, just again with sharp cutting edges.
As the only option, it includes a guard over the middle of the mowing disc—it is missing with 7 and 9 blades. With the SILENO models, that pays off because they often run in the same garden for years and, in the process, inevitably mow even in damp weather: Without the guard, the sticky clippings collect season after season at the blade attachment point.
For anyone who wants to keep using their device with as little maintenance as possible, this is the obvious choice.
7 blades – the noticeable difference
One more cutting edge, and the cut pattern becomes more even. For many SILENO owners, this is the answer to the dissatisfaction that otherwise leads to conversion attempts—no tinkering, no risk.
Especially useful when the lawn is kept short and the robot drives at short intervals.
Without center protection: In dry weather, it makes no difference; in damp conditions, the 6-blade version is easier to maintain.
9 blades – for a well-groomed ornamental lawn
The densest blade arrangement delivers the finest look when the SILENO runs every day and only trims the tips. Individual blades that remain standing—noticeable with six cuts—disappear here.
For longer mowing pauses and stronger growth, six or seven blades are more robust—the same work is otherwise spread across too many narrow edges.
Also without middle protection—during daily operation on short grass, hardly relevant.
How you can tell the timing
Buy blades individually as replacements
Gardena includes multiple sets of blades with the devices—having a supply is part of this series. The 60 cm replacement blades set including screws lasts for many seasons and makes the switch a routine instead of an ordering process.
