BX starting rough

[Cherokee180]

I was reading my BX manual and it said in warmer temps (I think like down to freezing or so) to only use like 3-5 seconds of glow plugs. Mine is in a warm garage, and after about 5 seconds and fires right up. Maybe I am not using enough????

When it's under 30 degree's I always use the 1-1000,2-2000 and so one even down to 10 degree's never have to get past 1-10000 [count slooow]. Throttle closed till oil presure comes up.It will smoke and idle a little rough for a few seconds normial for a diesel.Fuel treatment for sure,when the weather gets to 40 degree's I start adding it to my fuel,that way when it gets cold it's ready.

Since the cold, my still shiny BX 1860 starts rough. Smoke, trying to fire, then it sputters and fires up. I've let the glow plug go from a slow 25 count to a slow 55 count, no real difference. I haven't been using it that much lately, the last time I put diesel in it was probably a few month ago. It is finally ready for a top off. Is it likely the old fuel? Or should I count longer slower with the glow plug on? I've altered my timing with the glow plug, as well as had to start in 15 degrees, as well as 50 degrees with no real difference. Any advice is appreciated.

It sounds exactly like the problem that Jeepfreak had with his new B3200 where the timing was off by 8 degrees. His dealer readjusted it for him to 0 degrees and it works fine now, does your BX1860 shake a lot at low R.P.M.?


I would strongly suggest you contact the dealer as they have been changing the timing on the small engines when the tractors are assembled here to placate the EPA and the new pollution regulations for small "garden tractor engines".


I will either post the the new regulations if possible or link to them for everyones benefit here.

Are you certain the glo plugs are working??? In this weather mine starts with 5 seconds of glo. A cold diesel will smoke and sputter a couple seconds till it gets some heat in the cylinders.

You want to make sure the throttle is open a little, that helps a lot. I have mine at about 20% open. When its cold out, mine will sound pretty nasty at first, very rough. After a few seconds, it sound better. If its really cold, below zero, it sounds really bad at first.

This is a real good question that should be resolved 1st off.

you either have a poor battery, poor GP's, crappy engine oil or bad fuel..I do no use fuel adds, Amsoil oil and at 0f to -15f below NEVER glow more then 5 seconds MAX ....starts all the time...

I would expect that the start procedure for the BX 1860 is the same as all the other BX series tractors. The following is right out of the operators manual.

All levers in the correct position, parking brake set, etc.

Set throttle lever to about half way

Set key to on position and check dash lamps.

Turn key to "Preheat" position, 2 to 3 seconds for temps above 32F,
5 seconds for temperatures between 23 and 32F,
10 seconds for temperatures below 23F

Turn key to "Start" position and release when engine starts.

The following is my input:

If the engine is started with the throttle in the closed position, it is going to shake and shudder. Preheating for 25 to 50 seconds may shorten the life of the glow plugs.
Personally, I have never preheated for more than 5 seconds.

I'm having the same type of problem with my Massey.

1) Length of time for glow plug activation makes no difference.

2) 50 hours service just completed(replaced filter).

3)Glow plugs are working correctly, I pulled them and checked each one individually.

4) Air filter is clean.

5) Throttle position makes no difference, 1/4, 1/3, 1/2, 3/4, full throttle.

Tractor sputters, then shuts off..........usually the third try it keeps running.
Outdoor temp is about 17F degrees.

I'm leaning towards fuel quality.(about the only thing left).

Thanks to all for the response. Been out of town for the Holidays, and this is my first chance to read the replies. Any and all out there, I know nothing of glow plugs. First winter with my first diesel. I will try to cycle the plugs if I in fact knew what that meant?.?. I assume hold, count to 5, let go, repeat? Tractor is stored inside a sometimes heated barn. Once it is warm it starts great, don't know if that means anything. Is it possible that the clicking that I hear when I am pre-heating is fuel being pushed into the engine? Am I in essence flooding the engine by holding in the glow position for too long? The chugging being too much fuel? It's generally between 25-40 degrees in the barn. Or am I expecting my diesel to act like gas?
