Perfect KK mower

Designed to deal with heavier working conditions, the Perfect Van Wamel KK mower series will chop prunings up to 10cm (4”) diameter as well as grass and other vegetation such as weeds and cover crops. When fitted with the side chutes, the KK mower can be used to distribute organic matter at the base of the trunks to provide nutrients and act as a blanket barrier to discourage further weed growth.

For maximum security and minimum maintenance, the standard configuration of all KK mower models includes a Walterscheid PTO shaft, a heavy oil bath gearbox with spiral-toothed gears and multiple V-belts (depending on the model and working width) to secure an indirect flexible drive.

The unique Perfect flails are made out of cast steel (sharper and more consistent in weight) and comply with the highest demands regarding insensitivity for cracking and wear.

The standard 2.2 kg heavy-duty flail is less sensitive to obstructions, and chops wood up to 10cm (4″) diameter. The KK mower can also be fitted with special 0.9kg flails that feature a single flat cutting edge that provides a clean and neat cut and an excellent distribution of the cut material.

To extend the life of the mounting ears, extra strong 20 mm bolts are used to mount the flails to the flail rotor. And to keep vibrations to an absolute minimum, all Perfect flail rotors are balanced twice.

A rear roller with a large diameter (152 or 219 mm), large wall thickness and scraper is standard on all models. The easy-to-replace rollers are mounted using large diameter bearings with unique special covers to prevent mud, humidity etc. to enter which extends their lifespan.
