Claim 6
Dependent Claim
63 words
The invention claimed in claim 1, claim 2 or claim 3, in which the grapple means includes a first pivoted grapple arm which is bifurcated to define two spaced apart tines, and a second pivoted grapple arm defining a single tine adapted to pass between the tines of said first grapple arm when the grapple arms swing toward each other about their pivots.
Claim 7
Dependent Claim
112 words
The invention claimed in claim 1, claim 2 or claim 3, in which the arm means includes two offset arms depending downwardly from the frame member, the arms being pivotally mounted for swinging movement toward and away from each other, the roller means comprising two rollers, one in each of the said arms, the rollers in op-erative position being adapted to press inwardly against the lower side areas of one or more tree trunks clasped between the arms; and in which there is further provided an auxiliary drive roller adapted to contact one or more tree trunks from above, thereby defining with the first-mentioned rollers a three-point grip on the tree trunks.
