Plough leg protection systemsfor all working conditionsAuto reset plough legprotection (Non-stop hydraulic)comfort1 - Adapting to all working conditionsDesigned for stony and / or heavy conditions the Non-Stop Hydraulic (NSH) system allows continuous ploughingwith the plough legs automatically folding out of workupon hitting an obstacle and immediately returning intowork again once the obstacle is passed. No need toget out of the tractor and no need to replace bolts. Thesystem also acts as an excellent shock absorber whenworking in pebbly or flinty ground absorbing all thevibration, increasing the life of the plough and increasingcomfort for the driver.VARIBAR system: An optional system allowing instantcontrol from the tractor cab of the NSH pressure at theshare point.MAXIBAR system: The Maxibar option allow the pressureat the share point to be increased giving an adjustmentrange of 600 to 2500kg yet conserving the supplenessof the system. The option is particularly useful in heavycompacted ground.2 - A unique conceptThe basic concept of the hydraulic non-stop plough legsafety system gives a rapid break-away when a obstacle ismet and yet an increase in pressure thereafter bringing thebody quickly and firmly back into work.Advantages of the NSH system:• Long life and reliability - hydraulic technology is more reliable with no wearor friction and fewer moving parts (just one articulation point andtwo moving parts per leg).• Weight saving - compared to a mechanical auto reset system the NSHsystem is 25kg lighter per leg.• Ease of use - the pressure at the share point can be quickly adjusted from600 to 1300kg by simply inflating or deflating the accumulator mounted onthe headstock.• Excellent performance - plough leg resetting is quick and positive once theobstacle is passed with no “drumming” of the plough bodies in work.• Compactness - the NSH tie rod is located inside the plough leg structureand the hydraulic cylinder incorporated into the leg profile for the maximumpossible clearance and minimum obstruction to trash and vegetation.• Exceptional obstacle clearance - the share point can lift 60cm vertically outof work and 20cm sideways.Heavy duty plough legarticulation and tie rod• All pressure points receive a specific heat treatmentprocess.• With just one articulation point all the forces put throughthe plough leg are transmitted in a straight line through aone piece forged and heat treated tie rod.25002000150012001000600Effort at share point (kg)MAXIBAR effectAdjustment rangeNSH KUHN 150 barsNSH KUHN 90 barsKuhn has chosen the mostadvanced auto-reset systemon the market for maximumcustomer satisfactionMechanical NS system10 20 30 40 50 60Lift height (cm)7
