I have a L4600HST. Tractor is running but only at low RPM. Linkages are working. Tractor will just not respond to throttle. More alarming is the fact that the crankcase is overfull. I drained around 4 quarts of very thin oil to bring the dip stick level to the mid range on the stick. I have heard that the fuel pump diaphragm may be the issue. I understand how this would explain the high oil level as diesel can enter crankcase. My question is, "Would this also explain the tractor running at low RPM but not responding to increase throttle?
My gut says it might, but wondered if anyone could confirm.
