Model for even better traction with a new design! Thanks to the new design, the spikes come together more pointedly and penetrate into the ground, providing your robotic lawnmower with additional grip. WARNING: STAINLESS STEEL IS HARDER THAN ALUMINUM. DO NOT BUY COATED OR OVERPRICED ALUMINUM SPIKES. CHOOSE STAINLESS STEEL. 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 handle any incline, even in bad weather or wet conditions. Wheel replacement is possible without removing the spikes. The screw connection is made directly on the wheel. STAINLESS STEEL spikes extend 9 mm above the wheel, ensuring optimal traction and excellent grip. STAINLESS STEEL spikes are ideal for upgrading worn wheels and restoring optimal grip.
