Machines

2 basic types. 1) A hand-held machine, with the motor in the handpiece, with an electric lead. Use for small flocks, or dagging large flocks. Either 12 volt battery operated, or 240 volt mains electric versions.
2) An Over-head machine, with a 6 foot flexible driveshaft, and handpiece. Ideal for both full time-shearing, and crutching and dagging. Either 12 volt battery operated, or 240 volt mains electric versions.

Hang-up machines, with option of flexible or solid driveshaft, coming down to a handpiece. Choice of new handpieces, or buy without to use with your existing handpiece.

Also choice of traditional "pin-drive" fitting between the handpiece and driveshaft,
or newer, safer, "worm, or spline drive" fitting.
