BX1800 getting a little hard to start

[4Kings]

My BX1800 with 750 trouble free hours has become a little tough to start. I've had it since new and I have always just turned the key and held it until I hear the first click, then fully turn the key to start it. Over the last few weeks I have found that I need to advance the throttle just a tad before it will fire.

Once it's started and warmed up, it will restart with the throttle in the up position. I did change both fuel filters this summer and I've always been on schedule with all the other maintenance.

Is this a sign that something needs attention. If so, what.

Thanks
Jim

I think the first click only means the fuel pump is on and fully primed. Are you giving the glow plugs time to warm up before cranking it? The book on my BX1850 gives some guidance on holding the key in the glow plug position for 5 seconds when below a given temperature - say 50 degrees, and to hold longer for times when the temperature is below freezing. Don't recall the specifics on the temperature ranges.

I always hold it longer after the first click, at least 5 seconds. It's stored in a warm garage so cold temps aren't a problem. Been starting it that way since new.

4Kings,

I don't think you are having a real issue here but in colder temperatures on the first start (after sitting a while), you need to heat it for a few seconds.

It has little to do with the heat in the garage but the heat in the combustion chamber, which is a function of cranking speed and compression pressure without the starting aid. It takes about 700 degrees to light Diesel fuel and you have to spin it up pretty good to get that kind of heat.

The glow plug will make things happen faster and the battery and starter life will likely be longer if you heat it first.

Good luck!

Dont know. My L3450 has gotten so it wont start at Lo idle -- ever. I always have to advance the throttle a bit if set lo when starting [hit the foot throttle in this case]. Starts and runs good. Runs at lo idle fine immediately after startup. I think the fuel is not feeding at cranking speed at lo throttle setting. I dont know if this portends anything. Im not worried because its seems a totally stable shift in characteristic. Like you, Im curious.

I believe the owners manual for my BX2350 says to crack the throttle something like halfway to start it. Mine also starts a little hard if its been sitting for a week and a couple seconds of glow plugs helps alot.

The manual for my BX 1800 recomends giving some throttle before firing it up. I didn't read that til I'd put 1000 hours on the machine starting without any throttle. I now have tried starting it with some throttle and it doesn't seem to make any dif. I am of the opinion that a bit more glow plug is the real key.

My tractor only has 50 hours on it, but it has been interesting to me that it seems to start just a *little* harder now when it's only getting used occasionally on weekends, than it did when I was running it every day or two in the summer.
Maybe I should use it to get the newspaper more often.

Could be ULSD?

How's your battery? I just put a new battery in my tractor and I can't believe how much quicker it starts. I didn't really notice that the battery was going before it completely died but once I put the new battery in I realized that it had been taking longer to start for the past few months.

So my recommendation is to check the voltage on your battery before you start it the first time.
