many years ago..these old dozers just had a cable..that killed the engine..most drivers, would reset the cable, after killing the engine..truck driver hauling one, in cali...had to stop real quick..he didnt have chains on dozer..and the forward surge of the truck having to stop quick..restarted the engine..and dozer ran over the top of the pete..killing the driver...it then ran almost 2 miles, on hwy 58.in cali...before anyone could get onboard to stop it

Looks like a Caterpillar D11 which weight between 115 and 124 tons fully assembled and ready to go.

the tires are flattening, maybe too huge.

That is a HUGE bulldozer being hauled by that Pete.
