Cause detail: AN OPERATOR RIGHT-OF-WAY MOWING CREW WAS OPERATING A FRONT-MOUNTED TREE CUTTER NEAR A DRAINAGE DITCH. WET CONDITIONS DUE TO RECENT RAINS AND FLOODING CAUSED THE TRACTOR'S FRONT TIRE TO SINK INTO THE BANK OF THE DITCH CAUSING THE TREE CUTTER BLADES TO CONTACT THE EXPOSED PIPE UNDER THE WATER SEVERING THE PIPE AND CAUSING THE PIPE TO RUPTURE AT THE LONGITUDINAL SEAM. THE TRACTOR AUTOMATICALLY SHUT DOWN ON POWER TAKE OFF (PTO) STRESS SO THERE WAS NO IGNITION OF THE LEAKING GAS. THE TRACTOR OPERATOR RECEIVED A HEAD LACERATION AND WAS TREATED AND RELEASED.
