Description
0781 120 1117 – STIHL® Special Gear Box Grease (Genuine OEM)
STIHL® 0781 120 1117 is a genuine OEM special gearbox grease engineered specifically for high-load bevel gear heads, angle drives, and drive tube gearboxes used on STIHL brushcutters, trimmers, Kombi attachments, cultivators, and professional clearing equipment.
This grease is not interchangeable with HS hedge trimmer grease (0781 120 1109). It is formulated for slower-speed, high-torque gear systems where extreme pressure protection and long-lasting lubrication are critical.
