The STIHL YARD BOSS® pick tines cultivator breaks up weeds and hardened soil in the garden without disturbing nearby plants. The pick-style tines deliver exceptional control while effectively loosening hardened dirt or mulch. This is the standard attachment for the MM 55 and MM 55 C-E STIHL YARD BOSS® lawn care systems, so you can prepare soil for planting and keep your garden areas perfectly maintained – no assembly required.
