1. A working vehicle comprising:
- a vehicle body;
an air breathing fuel consuming internal combustion engine carried by said vehicle body;
an air intake system for said engine including a primary air filter and a pre-cleaner for collecting larger particles, said pre-cleaner having a conduit to carry away said particles;
a cooling system connected to said engine, said cooling system having a heat exchanger through which air flows to remove heat from said engine;
a device for removing debris from the air flowing through and upstream of said heat exchanger, said debris removal device having a conduit for carrying away debris;
a device for pulling air through said debris conduit; and
a venturi device interposed in said debris conduit and having a throat connecting to said particle conduit for removing particles from said pre-cleaner.

Abstract
A work vehicle operating in a highly contaminated environment has a radiator with a rotary screen debris removal device upstream of the radiator. The debris thus removed passes through a fan for disposal away from the work machine. The engine is an air breathing fuel consuming engine and has a pre-cleaner for removing larger particles of air delivered to the engine for combustion. A conduit extends from the intake air pre-cleaner to a venturi device adjacent to and upstream of the fan for continuously and effectively removing particles from the engine air pre-cleaner.
