IH Lowboy 184

Postby leeedwin9 » Mon Apr 20, 2015 5:39 pm

I have three IH 184 lowboys, each with a LB59 Woods finish mower. My favorite 184 began to stumble last summer and by season's end wouldn't operate the mower deck. It just goes slower and slower to the point that the engine will die unless the clutch is depressed. Then the engine slowly recovers RPMs and the process begins again. I switched decks so that the best deck is now on that tractor, but it didn't help. The latest deck has great bearings and sharp blades. As a test I removed the deck belt and turned on the electric PTO. The engine pulls hard even with the belt off of the PTO pulley. Regarding the engine, it has smoked some for the past 5 years or so, but always starts right up. I replaced the spark plugs and the coil last fall hoping for an improvement, but didn't see much difference. My local dealer was a Farmall dealership, then reduced to a Farmall Parts dealership, but now he only sells and services Cub Cadets, no IH stuff. I live in N.E. Indiana. Can anyone suggest a person/shop within a reasonable distance that might refresh my 184 for me at a fair and reasonable cost?

Sounds like a great candidate for a cubfest.

If you can trailer it to the western chicago suburbs id be glad to help you with it. Have you checked your governor linkages and springs? You said you replaced the coil. Hows the rest of the ignition system, points, plugs, wires, distributor cap, rotor, etc.?
A good ole' carburetor cleaning did wonders on my 154.

You said it happens even with the PTO belt off. Does that mean it doesnt happen when the PTO is switched off? Only when the PTO is switched on?

Yes, sir. It runs and drives quite well until I switch on the electric PTO. Then with the PTO spinning, even with no load on the PTO, it becomes weak and the engine runs considerably slower. The governor may be the issue. I do not know much about governors.

Just spinning the pto pulley wouldnt pull enough horsepower to cause the engine to bog down...unless maybe the bearings on the pto shaft are binding up causing the engine to struggle to turn it. Do you hear any unusual noises went you switch the pto on?

A couple of thoughts come to mind with the 184.
1) The belts turn all the time. If friction increases significantly when you turn on the PTO switch, then there may be a bad bearing or a misalignment of the PTO shaft.
2) The electric PTO clutch eats a bit of electric current. Perhaps the electrical load on the alternator is exposing some issue in the electrical system such as a bad connection to the battery? The alternator is more than capable of providing the amperage, I am just proposing a far reach attempt to help.

Interesting possibility that I hadn't though of. I think there is a connector at the PTO pull-in coil. Unplug it there. Then try throwing the PTO engage switch. If it still pulls down, there is some electrical problem between the switch and the coil (probably a short of some type). If it doesn't pull down, use a second battery and jumper wires to engage the PTO. If it doesn't pull down, the problem is likely to be electrical, the PTO coil. If it does pull down, you are back to a mechanical problem such as a bearing in the PTO.

This is all still assuming the problem isn't the governor, which is the first thing I would verify.
