While my Honda 35cc is considered heavy by most at nearly 15lbs (trimmer head included), it is far smoother than any trimmer I've ever used. These will accept a blade...and coupled with a ton of low-end torque and overall power, I think you'd be impressed. The padded handles coupled with a cable drive help to absorb vibrations throughout the unit. Craftsmanship through and through. This is a true 4-stroke requiring no mixed fuel as it has a separate oil sump and will run on reg unleaded.
