I have two very solid units here, HUSQVARNA RANCHER 51 and HUSQVARNA RANCHER 55. These are some of the best firewood saws ever made, good power, usually cut a pickup load of firewood on a tank of fuel. Power heads only. 16 and 18 inch bars are best. For more info on what has been done to each saw let me know. 225.00 for 51, 250.00 for the 55. I also have a 455 Rancher with a 18"bar and chain, it runs good and is in good shape 225.00.
