A little clearing/brush bow on a SD25.

A setup using the clearing/brush plunge type bow bar and under 50cc power head is a common sight at a Christmas tree farm over much of the USA and Canada. The Christmas tree is small and the typical felling operation is to reach under the limbs with the 20" long bar and make a single plunge cut. Ideal for a small bow type bar.  These bars are often 20" long but are only some 8" across the radius on the front where the cutting is done. You can run either .325" or 3/8" chain on the bar as there is no nose sprocket tooth pitch to worry about.  They might be .050" or .058 gauge depending on what area of the country they are from.
