I got too close to the landscaping rocks. Our snowblower picked one up and it got stuck between the auger and the auger casing. Twice. The first time I pried the rock out. The second time, it was too securely wedged in and won't budge. Looked on here for similar problems. One person with a chain wrapped around the auger was advised by Amber (with EGO) to remove the rotor assembly. But no instructions were given and I cannot find instructions on the internet or in the manual. EGO folks, can you provide me with instructions.
