Folks
I have a fantastic (very old) Husqvarna 244-RX, 2-stroke, Straight Pole Brush Cutter/Strimmer.
I always used a solid billet alluminium head. This allowed for x2 lengths of strimmer line to be inserted in a X pattern. Now I want to install a Brush Cutter Blade.
Unscrewing the Strimmer Head I am presented with a smooth flat disc cover. through which the shaft for attaching the head/blade etc protrudes. On this flat surface, sits a plastic washer. Do I just sit the blade over the shaft (there are no spline holes in the blade) and bolt up using the "blade cup" and left hand locking nut? or should there be a locating washer/ woodruff-key arrangement to stop the blade slipping between the flat and the cup?
I am thinking that the blade is maybe designed to slip if it contacts a fence post or something solid? This avoids the blade torquing the machine if it attempts to stop spinning.
So what I have is:
Flat surface with washer that spins.
Drive shaft that bade locates over.
Cup that locates over shaft and then is tightened down by left hand nut.
No locating pins/dowels/splines on the blade or the strimmer.
