A guide bar having fluid conveying channels at the opposed sides. The channel on one side provided by the manufacturer with holes or orifices for dispensing treatment fluid from the channels onto a stump being sawn. The other side provided with markings to guide the operator in making holes or orifices at the time the bar is to be inverted. The markings may be dimples to provide centering of a piercing tool. They may also be provided at the sides of the channel and different marking sets will provide for different sizes of trees being cut.

Guide bar for tree harvesting including stump treatment

A chainsaw guide bar includes a bar body and a nose member removably attached to the bar body by an elastic snap-in coupling, eliminating the need for separate fastening elements. The snap-in coupling includes dimples formed in tongues of the nose member, the dimples being received in holes formed in a web of the bar body. The dimpled portions of the tongues are elastically flexible in a thickness direction of the guide bar to enable the nose member to be inserted or removed.

Replaceable nose member for chain saw guide bars

A nose sprocket for the saw chain of a chain saw includes radially projecting teeth, each tooth having leading and trailing edges. Each of those edges includes a straight inner portion and an outer portion that deviates from a radius of the sprocket by a greater amount than the inner portion. The teeth are long enough to enter a space formed between side links of the saw chain.
