WE CONDUCTED AN OPERATIONAL MOTOR GRADER PERFORMANCE TEST

AN OBJECTIVE EVALUATION OF AVAILABLE MOTOR GRADERS WAS CONDUCTED TO WRITE SPECIFICATIONS FOR WISE PURCHASE. A WORK SITE WAS SELECTED FOR A FIELD TEST TO DETERMINE WHICH GRADER PERFORMS THE ESSENTIAL BASIC OPERATIONS BEST. THE PERFORMANCE TESTS THAT WOULD BE CONDUCTED WERE OUTLINED: DITCHING, BANK SLOPING, SCARIFICATION WITH REVERSE BLADING AND GRADING UP A SLOPE. THE SCHEDULED EQUIPMENT TEST WAS ANNOUNCED TO EQUIPMENT ENGINEERS AND SUPERVISORS IN THE AREA. JUDGES WERE SELECTED AND GIVEN SCORING INSTRUCTIONS. COMPETENCE OF THE OPERATOR OF THE EQUIPMENT INFLUENCED THE SCORING TO SOME EXTENT. THE JUDGES SUGGESTED SIMILAR EVALUATIONS WITH SPREADERS, TRACTORS, MOWERS, ROLLERS AND LOADERS. THIS FIELD TEST, COMBINED WITH OTHER FACTORS SUCH AS INITIAL COSTS, MAINTENANCE COSTS, EXPECTED YEARS OF LIFE, AVAILABILITY OF PARTS AND SERVICE, HELPS TO MAKE A FINAL DECISION TO PURCHASE THE MOST EFFICIENT MACHINE TO MEET OVERALL REQUIREMENTS.
