VibraStop / PowerPackDeep aerification and loosening is tough work, both for manand machine. If, for example, a tine strikes a stone duringoperation, the tine must lift the entire machine within a fractionof a second in order to overcome this obstacle. The jolts andvibrations that inevitably occur when this happens adverselyaffect not only the deep aerifier, but also the tractor and thetractor driver in the form of damaging jolts and vibrations.Consequently the quality of work suffers.To eliminate this fundamental drawback, <strong>Wiedenmann</strong> hasdeveloped two independently operating, exclusive dampingsystems - VibraStop and PowerPack. Together, they absorbperfectly jolts and vibrations caused by extreme compactionor stones. The result is unrivalled smoothness of running witha minimum of strain on the driver, tractor, deep aerifier andtools.QuickSetVibraStopQuickSetCrankshaftPowerPackPowerPackTwinDriveQuickSetPTO couplingSensing rollerTurf retainerOther machines on themarketThe tine strikes an obstaclein the soil.
