The top of the range JENNY comes in a range of widths from 1.05 to 2.00m and is somewhat heavier in design than the JUPITER.
The Jenny is suitable for tractors up to 55hp, working off a 540 power take off system. Again all machines are double-skinned and are capable of cutting material to 5cm diameter. A 3 or 4-belt drive-line, powers a heavy duty rotor assembly with hammer flails, incorporating an 8 stud internal rotor bearing. Each end of the rear roller is fitted with taper roller bearings. An adjustable rear hood complete with heavy-duty rubber flap and front flaps are standard. The JENNY range extends to a two model reversible range with one having a central fixed headstock with a two position manual offset and a second model complete with hydraulic side-shift. A 1000rpm gearbox is the final option.
