I looked at three new Huskies today, a 235, 435 and 450. The 235 remminded me of my Pouland, both 235 and 435 were hard to pull, much harder than the 450 (which and a larger engine). The 450 was much higher in price but the same bar length as the 435. Are there 2 grades of the Husqvarnas ? Does anyone know if the 235 and 435 series are any good and why the larger 450 was easier to pull?
