Stakes - Gardena

Gardena Stakes 4090-20 (Reference: 4090-20) - 100-piece kit for professional fixing of your robotic mower''s perimeter wire. These German-quality Gardena accessories guarantee a durable and reliable installation of your automatic mowing system, ensuring optimal maintenance of the guide wire in all weather conditions.

Applications and benefits

These stakes are essential for all robotic mower owners wishing to maintain their perimeter wire in perfect condition. They are intended for individuals during the initial installation of their robot, landscape professionals for their projects, as well as experienced users performing extensions or modifications to their mowing circuit.

The 100-stake kit effectively secures a medium to large perimeter, placing one stake approximately every 75 cm according to manufacturer recommendations. This density ensures uniform fixing that resists weather, trampling and regular mowing operations. Gardeners particularly appreciate these stakes during periods of strong growth when the repeated passage of the mower puts more stress on the wire.

Technical characteristics and compatibility

Made from UV-resistant plastic, these Gardena stakes feature an ergonomic shape designed to facilitate insertion into the ground while firmly maintaining the wire. Their double-branch design ensures optimal stress distribution, preventing wire deformation under tension.

Compatibility extends to all Gardena robotic mower models (Sileno, Sileno+, Sileno Life, Smart Sileno) as well as the majority of mowers from other brands using a standard perimeter wire. The dimensions have been optimized to accommodate 2.7 mm diameter cables commonly used in the mowing robotics industry. The mechanical resistance allows use on all soil types, from loose ground to more compact soils.

Installation and practical use

Installing the stakes requires no specialized tools. Position the perimeter wire according to the defined layout, then push in the stakes by hand or using a rubber hammer for firmer soils. Maintain 75 cm spacing on straight lines and tighten to 50 cm in curves to maintain signal precision.

For optimal installation, slightly tension the wire before fixing, without excess to avoid breakage. In high-traffic areas, push the stakes in until the wire is flush with ground level. This technique prevents snagging while maintaining magnetic signal efficiency. Maintenance is limited to seasonal checking of wire tension and replacement of damaged or lost stakes.

Expert advice and optimizations

Professionals recommend ordering this kit in anticipation of future needs, as stakes constitute the main wearing part of robotic mower installations. Always keep a reserve of 20 to 30 stakes for emergency repairs, particularly after freeze-thaw periods which can destabilize certain fixings.

To maximize the lifespan of your installation, combine these stakes with Gardena splice connectors during wire connections. This combination ensures perfect electrical continuity and facilitates maintenance interventions. When extending the perimeter, plan 15% additional stakes compared to theoretical calculation to account for terrain specificities. Experienced gardeners also use these stakes to temporarily secure the guide wire during landscaping work, thus avoiding costly accidental cuts.
