INSTRUMENTATION PACKAGE FOR MONITORING TRACTOR PERFORMANCE Academic Article uri icon

abstract

  • An instrumentation package was developed to monitor tractor performance on a John Deere 4440 tractor. Performance variables measured included front and rear wheel rotational speed, ground speed by Doppler radar, engine speed, differential speed, drawbar pull, axle torque, and fuel consumption. Speed comparison tests were conducted to determine relative differences between travel speed sensors (front wheel and Doppler radar) and clocked measurements. Results of field performance tests were documented for three tractor/implement combinations. When pulling a JD 230 tandem disk, tractive efficiency and engine load increased 10. 6% and 33. 4%, respectively, when the operating gear was increased from second to third. Specific fuel energy requirements decreased 24. 6%. When 'shift up and throttle back' techniques were practiced, specific fuel consumption decreased 14. 8% when pulling a JD 340 offset disk and 8. 3% when pulling a JD 100 chisel plow.
