This is my first tractor but I have an older Diesel truck, a 2000 Ford Excursion with a 7.3 diesel, and it seems like guys really like to build up their diesels and there's lots of aftermarket parts to get more performance. I was just wondering if there's anything similar for diesel tractors? Digital propane injection, exhaust upgrades, etc.. Any way to get a 19hp Kubota stock motor to put out an extra HP or two?
