We live in the Sierra Foothills with mild winters but hotter summers. I shear most of my animals yearly. The Super Ccara Llamas I never shear. I generally do just the main body. I use the Lister Star with premier llama blades. I send the blades to be resharpened to Premier in Iowa. They are fast and do a great job. I can shear 3 to 10 llamas per set of blades. They do wear out and Premier will send them back to you when worn out. There are other systems that will work but llama wool is unique and some systems will not work at all. Do not blindly buy something out of a catalog or online. Make sure it is recommended by a llama owner.
