John Deere has developed an advanced engine system that uses cooled gas exhaust re-circulation and paired it with an exhaust filter.  We also gave it historic power that breaks through the 400hp barrier among grow crop tractors.  That power meets IT-4 emissions regulations using just one fluid – diesel.  We call this integrated approach the new John Deere Power-Tech PSX 9 liter engine.
