That kind of pump package is often mounted above the main, apparatus-driven pump system and can easily supply a 1.75-inch line and a booster reel, or a 100 gpm bumper turret. Fuel mix should be 4 parts diesel to 1 part gasoline. Pump and roll capabilities can also be achieved with the chassis pto system. This makes fire control strategies a vital component of forest management and emergency management in Canada. [5] In California these engines are staffed with one firefighter and used for patrols; for this reason the unit itself is sometimes called a patrol truck or simply "patrol". The chassis total gear reduction can be lowered, which would increase the pto output speed at the required road speed. A wildland fire engine is specifically designed to assist in fighting wildfires by transporting firefighters to the scene and providing them with access to the fire, along with water and/or other equipment.
