Stihl Farm Boss 290 is a REAL chain saw. Great power, even for big jobs. Easy start. Great for on-the-ground work, but a bit heavy to handle up in a tree. If the blade is kept sharp, the saw "pulls itself" through the tree/cut with little effort your part. I use the saw primarily for cutting firewood for home heating and other jobs around the 21 acres (mostly wooded) that I own. The Farm Boss is a powerful saw. I've never had any problem with the oiler getting plugged. Always starts with just 4-5 pulls. It will cut through an 18" log of oak in less than two minutes. With a sharp chain, it practically pulls itself through the cut, requiring little effort on the part of the person doing the sawing. The only negative is that, if you do a lot of cutting up in trees, this model is a bit heavy. It might be best to consider a smaller/lighter model--Stihl has one for every job. Because of the power of this saw, be safe....kickback is deadly--with any chain saw.
