PURPOSE:To know easily run performance by providing an unloaded roller, loaded roller, hydraulic pump, detecting means, recording means, etc. CONSTITUTION:The 1st and the 2nd speeds per hour are calculated on the basis of the outputs of the 1st and the 2nd detecting means 7 and 8 which detect the rotating speeds of the unloaded roller 3 and loaded roller 4 and displayed on a display means 13, and the run distance is also displayed on the display means 13 in response to the output of the 1st detecting means 7. Further, the fuel consumption after measurement starting time is integrated and calculated on the basis of the output of the 3rd detecting means 9 which detects the flow rate of consumed fuel and displayed on the display means 13, and the rotating speed of an internal combustion engine is displayed on the display means 13 on the basis of the output of the 4th detecting means 10 which detects the rotating speed of a crank shaft; and the specific fuel consumption is calculated on the basis of the outputs of the 1st and the 3rd detecting means 7 and 9, and displayed on the display means 13. The display means 13 records graphically said recording contents on a long recording form 14 with plural recording pends 15-20 provided breadthwise at intervals. |
