I recently bought a '93 Altec drum "whisper chipper" for my landscape company and have not been to impressed with the performance. It has the 300 ci straight six ford engine and runs perfect with about 2000 hrs. The clutch is new and the drum bearings. I just don't think the knives are set right or something it is a major pain to get it to feed well. Occasionally it will grab a limb and eat through it in a second or two but for the most part you have to really work it to get it to take the limb. I am only chipping small diameter brush from 1"-3". Does this sound normal or is something not set up right or not sharp? I believe it is a 12" drum. If someone knows a good person for service in S.W. Ohio let me know.
