Update... Been using the tractor to shred a few times the last couple of weeks and it's been running good. In between shredding, I changed the hydraulic fluid, cleaned out the metal strainer, replaced the o-rings on the hydraulic lines, cleaned the air cleaner out, replaced the oil in the air cleaner, drained the oil in the injector pump and replaced the oil. The steering is fairly sloppy and I've found out the pervious owners broke something in the steering that was welded back instead of replaced. More importantly, I went to fuel up with ag/red diesel after a shredding session and now the tractor won't start. Prior to this tank, the tractor had only ever been ran on normal road diesel. If I put the throttle at half throttle, like I normally do to start, it just turns over like it normally would to start, but never quite gets running. I tried to start it on full throttle and the cranking seems to be happening slower at full throttle. Over a few hours, I tried it several more times, but got the same results. I purged the fuel lines and injector pump and the red fuel flowed out as expected. I've always used Power Service Diesel Kleen +Cetane Boost and have done so in this tractor also. Anyone ever had issues going from road to red diesel? my understanding is that the only different is the dye. Please understand I'm not trying to start a debate on the quality of various fuels.
