635H Skidder First Impressions


Forestiers R.B.E. Lasalle is a logging company owned by Richard Lasalle and his sons Eric and Benoit. Based out of Saint-Michel-des-Saints, Quebec, the company purchased the very first 635H skidder in March 2020. Once the machine clocked over 2,500 hours, it was a great time to catch up with Eric to get his impressions.
