  1. Andre Lafleur

    Best Sawmill in the market, I purchased my Green Monster in June and have been cutting log up the 35” with a 1 1/2” wide blade and 24 hp, with the solid 24’ long frame you could level in a few minutes.

    I recommend it

  2. Lawrence Rohenaz

    seems to be the best available for the price

  3. Johnny Wilson

    I have had the big red for about 2 half years and have not had any problems. so far I have cut about 750 trees into lumber, I am working on building a boat shed for a customer and have cut 2 10×10 x30 feet into 2 3/8 by 10 by 30 feet, this is one bad machine and does what I want no question about the service, Highly recommend this saw. looking to up grade to the green monster 30 foot cut because of the number of people wanting longer lumber
