Smokey, I noticed that your construction utilizes square tubing telescoping into square tubing. I'm curious how you deal with the weld seam inside the tubes.
Npalen- Google "seams impossible tool". It is a bearing sled for a 3/4" carbide burr that is shimmed to the tube ID and seam location. Works great, though it takes time to make the shims that locate it in the tube.

Before.

After trimming about 30, 0.5-3.5” limbs in 10 minutes. 1-2” limbs cut fast like being clipped at idle. Improving technique with experience.

Other jobs include trimming oak horizontal limbs 40’ long and larger than 20” diameter at trunk. Small Brush and grape vines cut use fwd/rev and loader control while running saw. Hard to get a meaningful photo.

Been low maintenance and rugged. Had yet to get bar stuck in kerf. Chain stall yes. Quick reverse then forward continues cut.

Generates a tremendous amount of limbs to move quickly. Can cut much faster than grapple and carry off. Cut most of time at idle with auto throttle on for moving.

Would be nice if the cut limbs would fall straight into the hopper of a chipper and get mulched without any more work.

How have you adjusted your bar lube since you started using the saw? How much have you added to your tractor?

I adjusted the chain oiler down but seemed to be dry on thick oak so adjusted back. It doesn’t use much oil. Time needed to run the saw is low because it cuts so fast. Added about 1.5qt some time ago to bring slightly above top line full. Still hanging around full after hundreds of cuts. All with original chain and 2nd bar.
