1 Sommer - 02/13/03NIOSH Tractor Workshop1 Display of Stability Data for Safe Tractor Operation D.J. Murphy and H.J. Sommer The Pennsylvania State University NIOSH Northeast Center for Agricultural Safety and Health

2 Sommer - 02/13/03NIOSH Tractor Workshop2 Fundamental Hypothesis Operators can learn to avoid tractor overturn Safety training On-line sensors and display

3 Sommer - 02/13/03NIOSH Tractor Workshop3 Fundamental Goals Display Stability information Safe operation

4 Sommer - 02/13/03NIOSH Tractor Workshop4 Past Efforts 1/8 scale overturn tractor and terrain board Farm safety presentations across the Northeast Scientific publications Full-size umbilical agricultural tractor Annual presentations at PA Ag Progress Days exposition Scientific publications

5 Sommer - 02/13/03NIOSH Tractor Workshop5 Full-size Umbilical Tractor Ford 2080, 3580 lbm, 36 HP, rear wheel drive, 300+ overturns

6 Sommer - 02/13/03NIOSH Tractor Workshop6 Current Efforts Cost-effective commercial sensors Validate using full-size tractor Which implements are most often involved in tractor overturn ? Overturn tests with implements Psychology and ergonomics of display

7 Sommer - 02/13/03NIOSH Tractor Workshop7 FY1 Accomplishments New full-size radio control (R/C) agricultural tractor Selected MEMSIC dual axis accelerometer ($15) and Atmel processor ($5) Temperature compensation for zero shift and sensitivity On-line display and on-board camera Validation tests at Ag Progress Days 8/02

8 Sommer - 02/13/03NIOSH Tractor Workshop8 Full-size R/C Tractor New Holland TN65, 5300 lbm, 47 HP, four wheel drive, 30+ overturns

9 Sommer - 02/13/03NIOSH Tractor Workshop9 Full-size R/C Tractor New Holland TN65, 5300 lbm, 47 HP, four wheel drive, 30+ overturns

10 Sommer - 02/13/03NIOSH Tractor Workshop10 Ag Progress Days 08/20/02 (MPG)

11 Sommer - 02/13/03NIOSH Tractor Workshop11 Side Overturn (On-board MPG)

12 Sommer - 02/13/03NIOSH Tractor Workshop12 Near Miss (On-board MPG)

13 Sommer - 02/13/03NIOSH Tractor Workshop13 Sensor Validation

14 Sommer - 02/13/03NIOSH Tractor Workshop14 FY2/FY3 Plans CAN bus for sensor and display Overturn tests with rear deck mower Liaison with PA DOT (data logging on mowers) Liaison with John Deere (CAN bus) Review overturn reports involving attached implements

15 Sommer - 02/13/03NIOSH Tractor Workshop15 Future Plans Sensor/display interface standards Overturn tests with other implements Display Ergonomics Cognition Psychology

16 Sommer - 02/13/03NIOSH Tractor Workshop16 Major Resources 1/8 scale tractor and terrain board 2 acre enclosed overturn test arena Full-size umbilical tractor Full-size R/C tractor Full-size R/C skid steer loader Sensor/microprocessor/display design
