Primero HK3967 Loader

wpe16.jpg (49295 bytes)

The Primero line of forest equipment is targeted to the requirements of the part-time contractors and the active woodlot owners.  The Primero line includes many features that are usually only found in equipment designed for professional users.  Such features are: a single beam frame, which enables the bogie and the stake frames to be moved to a desired position.   The trailer has hydraulic steering, which means that it has a side-shift feature which enables the operator to side-shift the tongue on the run.  That feature enables the trailer to follow in the tracks of the tractor.  The side shift can also be used to make sharper turns.  By side-shifting the tongue, one can also move the loader out, for longer reach.

The rotation torque for the boom is an enormous 9.5 kNm, which is rarely found even on professional equipment of the same size.  This great turning power comes from four cylinders and four racks on the turning mechanism.  The turning mechanism has other features usually only found on professional machines, such as roller bearings.  All joints have grease fittings, and every joint has a bronze bushing.

The loader is detachable from the trailer, and can be used independently on a tractor with a 3-point hitch.  A Valby woodchipper can also be hooked up to the "A" frame, and can be fed with the knuckleboom loader.
