About a month ago my tractor got hard to start it was very slow to get up to speed when starting. After started it would run ok. Then last week I had to hold the starter on until the engine got running, it seemed low on power and after about 5 minuets black smoke came out and it stop'ed and won't restart. I removed lines from injectors and very little fuel squirts when you run starter. Could it be the injector pump or the fuel injectors ? When I loosened the fuel supply line on Injector Pump lots of fuel flows and filter is ok. If its the injector pump where can I get one. I live in Monticello, Fl

I'd have the injectors tested before looking for a fuel pump

I found the problem the head gasket blown. What will this cost to fix ?
