Query: ZERO Stars for McCulloch

Weak PLASTIC Sprocket gear strips out after about an hour of normal use. McCulloch has not been in business for years, will not repair or supply parts. Warranty useless.This could have been a good tool, but for the poor design of the PLASTIC GEAR. It is the weak point and fails rapidly with normal use.Perhaps designed to strip to protect the motor? But it cannot handle even normal torque.Unacceptable for normal yard use.
