Is that the one that winches the log into the processor? I looked at them but haven't used one. If you can afford that model you can afford one of their big conventional processors. I looked at the sl as an inexpensive alternative. It was 35k as opposed to 38k for the next model up. Not much of a savings for a lot of hassle.
The salesman said the SL was primarily designed for processing in the woods on a small landing, hence it's ability to process unlimited length.
