T-849/1359/2012DEUTZ-FAHR, AGROMAXX 55 (4WD) TRACTOR-Commercial (Initial)16.4 Salient Observations:16.4.1 Laboratory tests:16.4.1.1 PTO Performance:i) The backup torque is observed as 27.1%.ii) The specific fuel consumption corresponding to maximum power wasobserved as 261 g/kWh against the declaration of 265 g/kWh, which meet therequirement of IS: 12207-2008 with regard to tolerance.16.4.1.2 Drawbar performance:During drawbar performance ten hour test, creeping of LHS & RHS rear tyre overthe rims was observed as 35 mm & 60 mm respectively, which was considered onhigher side. This should be looked into for necessary corrective action.16.4.1.3 Mechanical Vibration:The amplitude of mechanical vibration on various assemblies marked as (*) inChapter-8 of this test report is on higher side especially at left foot rest, right footrest and steering wheel. This calls for dampening down of vibrations to improve theoperational comfort and service life of components.16.4.1.4 Linkage drawbar:Some of the parameters of linkage drawbar conform to Cat.I and some of themconform to Cat.II. In view of the spirit of standardization, necessary improvementmay be incorporated.16.4.1.5 Operator’s seat:The Length of seat, Inclination of seat towards rear direction and Vertical distancefrom seat index point to the center of steering wheel does not meet therequirements of IS: 12343-1998. This should be looked into for necessary correctiveaction.16.4.1.6 Location and operation of operator’s control:Working clearance between position control lever and the mudguard does not meetthe requirement of the IS: 12239 (Part-2)-1996. This should be looked into fornecessary corrective action.16.4.2 Field performance test:16.4.2.1 Wetland cultivation (Puddling operation):No ingress of mud and / or water was noticed during puddling operation of thetractor and meet the requirements of IS: 11082-1984 (Technical requirements ofagricultural tractors for wetland operation). Therefore, the tractor is recommendedas suitable for wetland operation (Puddling).16.4.2.2 Haulage test:(i)The distance travelled per litre of fuel consumption with four wheel trailer wasobserved as 3.72 km/l against the declaration 4.25 to 6.5 km/l. This does notmeet the requirement of IS: 12207-2008 and therefore, should be looked intofor necessary corrective action.(ii) The fuel consumption with four wheel trailer was observed as 46.84ml/km/tonne against the declaration 25 to 40 ml/km/tonne. This does not meetthe requirement of IS: 12207-2008 and therefore, should be looked into fornecessary corrective action.16.4.3 Wear assessment and final inspection:During wear assessment and final inspection, the axial clearance of big endbearings was observed as 0.50 mm and which approaches to the discard limit of0.50 mm, that too, in 99.7 hours of tractor operation. This should be looked into fornecessary corrective action.CENTRAL FARM MACHINERY TRAINING & TESTING INSTITUTE - BUDNI Page 45 of 48
