Model for even better traction with a new design!Thanks to the new design, the spikes come together even more pointedly and penetrate even into the ground, giving your robotic lawnmower additional grip. WARNING: STAINLESS STEEL IS FAR HARDER AND THAN ALUMINUM SO DON'T BUY COATED AND OVERPRICED ALUMINUM SPIKES, CHOOSE STAINLESS STEEL DIRECTLY. Easy to assemble: Place the two spikes on the respective unscrewed wheel of the robot and screw on. The supplied precision screws connect the spikes to the wheel perfectly without protruding. The robot is immediately ready for use and can cope with any hill, even in bad weather and when it is wet. A wheel change remains possible without removing the spikes. The screw connection takes place directly on the wheel. STAINLESS STEEL spikes are 9 mm above the wheel and thus optimal traction and excellent grip. STAINLESS STEEL spikes are also great for upgrading worn-out wheels and giving them optimal grip again.<br><br>Size: 170mm Suitable for lndeg6 lawn mower robot for indego Xs 300 for Indego S 500 for indego M 700 for indego M+ 700 for Indego S+ 500 Colour:Silver Material:Stainless steel<br><br>Package Contents: 1x Wheel Assist Wheel<br><br>Only the above package content, other products are not included.
