I have a New Holland TT60 that only has 154 hours on the meter. First, a bit of history. Back in 2007 when the tractor only had a few hours, it would randomly die in the field, but would always re-start, sometimes minutes later and sometimes hours later. The selling dealership sent a guy out with a trailer and ran it back to the shop. He brought it back a few days later telling me that the solenoid on the injector pump was the culprit. Since that time the tractor hasn't missed a beat.
Now, fast forward to last Thursday. A buddy was disking a few acres when the tractor just died on him. We let it cool down and added about 5 gals of fresh diesel thinking it may have run out of fuel (gauge showed about 1/2 tank and we could see some in the tank, but tried new fuel anyway). After adding fuel, the tractor fired right up but while driving back to the barn, it sputtered and ran like crud. I let it sit till Saturday afternoon without doing a thing. When we tried firing it up, we couldn't get a thing other than cranking. I put a new fuel filter on and drained all the diesel (around 15 gallons). Thinking back to the fuel solenoid, I contemplated replacing it, but it is a $130 part and upon further inspection, realize that the part on my tractor is the original piece, inasmuch as I can tell it has never been removed (covered and sealed in original paint, same as rest of engine). Nonetheless, I took it off the injection pump, made sure the plunger was moving freely inside and put it back on. Tractor still cranked, but didn't run. Thinking to myself, "what could keep it from running?" I decided that the sensor under the seat might be the problem so I jiggled the wires at the connector, set the seat back down and tried firing up again to which it started right up without hesitation.
Now to the problem at hand. The tractor runs great at idle, up to 1600 RPM and above 1800 RPM, BUT at around 1700-1800 RPM the thing misses, sputters, bogs, etc. making no power whatever....What the heck? It does it sitting still as well as while driving.
Any thoughts? Remember it has fresh fuel and a new fuel filter. I also bled the fuel lines, checked the oil level, radiator fluid, air filter, etc.
