R4780-140 HPThese models have some common designfeatures which make the Gregoire-Bessonplough well know :A great choice of safety devices to adapt to all the conditions• Simplicity• Performance• RobustnessA robust shaft adapted toextreme usesThe shafts of the Gregoire-Besson ploughare at the same time compact (limitingthem efforts on the shaft) and dig(improving its impact resistance, by onebetter absorption of the constraints).Supports (specific) mouldedwith strong resistancecapacitiesTo ensure a good resistance in the time ofthe elements, the body is a welded castsolid part mechanic. The moulded supportis hollow, which increases its solidity byabsorption of the shocks. With the fleeingcontour of the body, the vegetable residuesare evacuated easily.Specific safety for the easygrounds (C)The body is made in only one block. Oneshearbolt with shearing ensures its safety.In the event of shocks, it is sheared,making it possible the body to swivelaround the obstacle.A safety bolt for the heavysoils (B)Rupture of two bolts of shearing onthe level of the articulation ensure thewithdrawal of the body in front the obstacle.According to the soil conditions,various resistances of bolts (90 to 130 kg)are available. The whole of the body iscast solid what limits articulations andwearing with time.A robust mechanical nonstopdevice protectionwithout maintenance (N)The spring, placed inside the elementhas at the same time a capacity of shockabsorber which absorbs the shock In caseof obstacle, and a capacity of restitution,allowing a fast return of the element inthe ground. The system is assembled ona double linkage ensuring broad releaseof the body and the best reliability intime.A hydraulic safety highperformance (Y)Hydraulic safety not-stop is one importantcharacteristic of the range. Gone upon 4 independent kneecaps, each bodycan as well move from top to bottomthat from left to right without the articulationbeing damaged. This systemof non stop safety uses a double linkageand a jack fixed in end of body. Thisspecificity ensures reliability of the system.Double frame: a great robustnesswithout excess of weightThe Gregoire-Besson ploughs are equipped witha double carrying frame until last body. Thistechnique specific to Gregoire-Besson makes itpossible to work in 8 faces. It is the guaranteeof a great solidity of the plough while limitingthe extra weight of the plough.A connexion frame-headstock byparallelogramThe adjustment of the first furrow (offset) isdone by a mechanical turnbuckle (or hydraulicsin option).The adjustments of the offset and the alignmentare independent what makes it possibleto adjust one without modify the adjustmentof the other.To adjust your working witheasilyTo adapt your working width in allsimplicity; the link between the body andthe frame is made via an adjustable support.It is then possible to modify the workingwidth of each body following 5 positions:12, 14, 16, 18 and 20 inches.R47Transport kit: to simplify andmake safe your travels115 mm120 x 120 mm3 4 5 6 (RC 47)90 / 10073 / 78 cmC, B, N, Y11 à 20 ‘’/ 12 à 22’’1150 1300 1480 170080 110 130 140Great amplitudes of adjustments for betterproductivityThe adjustment of the working width of the first furrowis carried out via the internalturnbuckle. Thecapacity of adjustmentmake it possible to hitchthe plough whateverthe internal way of thetractor.The adjustment of the realignment of the plough comparedto the tractor iscarried out thanks tothe external turnbuckle.In option, this one canbe replaced by a automaticram of realignment(strongly advisedfrom 4 body).Hitch: priority with the facility of attachmentTo fulfil the requirements of each one, various types of hitches are available(fixed, automatics, …). Facility of attachment of plough and the resistance ofthe locking pins are two characteristics which brings reliability and comfort forthe user.Frame: use of high quality steelsA very particular care is taken for the frame. Forthat, we use steels with very high yield stress andof dimensions of tubes especially studied to answerthe most extreme conditions. Each drilling for thefixation of furrow is reinforced using spacers toimprove longevity and the efficacity of tighteningon the carrying element.RJL RTTL 92 DRL 20Lateral depth wheels: to limit the spaceThis type of fitting limits to the maximum the overflow of thewheel.The RJL wheel can be used with a transport kit. The RTTLprovides the function of control depth and transport with asimple passage of one to the other. According to the modelchosen, different tires fittings are available. The RJL model isjust able to control the depth, when RTTL and DRL 20 modelsare also taking care about the transport.RL 93 RJR RTT85 RTTA92Rear wheels: optimum control of the working depthAll the models of this range are offering a wheel in rear position with various type oftires. This system is appreciated for its facility of adjustment and the improvement ofthe carry forward of load. Here still, various models of wheels exist, combined (RTTA92)or independent (RL 93, RJR). Do not hesitate to ask to your retailer.Wheels RL, RJR, and RJL can be supplementedby this kit to reduce the effortson the raising of the tractors, while improvingcomfort of the driver.600 x 9Tires200 x 14,510,75 x 1226 x 12,0-12
