I claim the ornamental design for a brushcutter handle, as shown and described.
FIG. 1 is a left perspective view of the brushcutter handle;
FIG. 2 is a top view of the brushcutter handle shown in FIG. 1;
FIG. 3 is a bottom view of the brushcutter handle shown in FIG. 1;
FIG. 4 is a right side view of the brushcutter handle shown in FIG. 1;
FIG. 5 is a left side view of the brushcutter handle shown, in FIG. 1;

The broken line showing of the brushcutter handle is included for the purpose of illustrating portions of the article and form no part of the claimed design. Any surface of the design not shown, including interior surfaces, also forms no part of the claimed design.
