Figure 13. — Drott Feller -Bunaher , Model 40 LC. The tree is severed at the base by the 

 shear 3 and controlled for bunching by the locking arm. 



Figure 14. — BM Volvo SM-880 Processor. The felled tree is grappled and returned to the 

 holding arm. On the return travel of the boom for the next tree, the tree in the 

 holding arm is prelimbed by the knives on the edge of the grapple arms; the tree is 

 then automatically transferred to the limber feed rolls and pulled through two 

 wraparound, belt-type knives. The tree is topped by a circular saw.
