The leaf blowers that last longest from the Stihl range are the petrol backpack leaf blowers, so you can reduce the number of times you need to refuel. With a full tank, a number of the Stihl petrol backpack leaf blowers can last up to 120 minutes, helping you to complete any job without the interruption of refilling and whilst maintaining a very strong amount of power. The smaller cordless electric blowers have a shorter run time of between 10 and 20 minutes, making them well suited to smaller landscaping jobs.
