Husquvarna here. I had a 455 Rancher and used it to cut over 1 million lbs of timber off my ranch. I moved up to a 545 XP and then I added a 372 XP to the line up. Mostly, I used the 545. I use the BRUTUS 372 XP is truly PRO Grade but its is HEAVY! IIRC fueled and oil + chain turn into about 19 lbs or so. It's a saw that comes with a bonus as a Gym Membership.
Starting these Huskys is not easy that I will say. Best to set it in the sun to warm it up because they don't start below about 70 F, they are NOT cold starters for sure.
Way back, I got a Stihl, but it was nothing but problems, and the local dealer just said Do this and do that, don't bring it back. Finally, I did bring it back and demanded my money back. All they gave was lip service, telling me there was nothing wrong, I just was not pulling hard enough other words but they never took it into the shop. It was still in warranty and I forced them to give me my $.
What we need is a chainsaw with a Starter on it...LOL
