I 'm watching and I also am laughing because I have a Whisper Chipper with a ford V8 16 inch by 10 inch throat and when I feed it I can almost hear it say MORE MORE. You have to have all the wood ready to feed it because it eats it so fast like you I have to watch the branches will whip as they go in 60 miles per hour past you.
Oh you have the big Whisper! Most are Ford 300 straight 6 and 12 inch drum. Dang good chippers though. Yours must be a monster like ours. Thanks for watching and commenting brother 👍
