Cold weather starting

[tonybada]

I just bought a B7500HST it did not come with an owners manual( I intend on getting one). My question is what is the procedure for cold weather starting? I have never had a diesel tractor with glow plugs.

Turn the key to the start position, and wait for the glow plug lite to go out then start the tractor.

Not sure about your model, but FWIW, on my B7800 the glow plug indicator light doesn't extinguish when it's ready to start. From the B7800 manual -

Over 32F

Preheating time 2 to 3 seconds

32 to 23 F

Preheating time 5 seconds

23 to 5 F

Preheating time 10 seconds


It also goes on to say:

COLD WEATHER STARTING

When the ambient temp is below -5C (23F) and the engine is very cold. if the engine fails to start turn off the key for 30 seconds. .... Make sure that the starter is not turned continuously for more than 30 seconds.

Hope this helps

Snoho3 is correct on starting procedure for the B7500.

Wow, the glow plugs work that fast? I thought I read somewhere on here that they were using the glow plugs for 1 minute. Well I will obviously try what you posted first. Where do you set the throttle?

[Snoho3]

The B7800 manual says to move the throttle "about halfway" prior to starting. Doesn't sound too exact. In fact, when I start mine I never move the throttle at all. Perhaps someone on here will tell me that I'm not doing my engine any favors, but I've yet to have a problem starting it.

One minute was for the older models. On my B7500 the above times work fine, just remember that seconds are not just counting to 3 unless you count real slow.

I do the same. In fact I start mine at idle. My thoughts are, the engine id cold and want the oil to circulate before increasing revs. Is this approach wrong?

[easygo]

I do about the same on my B7510 as it was described before. I actually give it 4-6 sec when it is warm outside and about 8-10 when below freezing. I start on idle too and when the oil pressure light goes out (about 1sec) I turn the throddle up to about 1500rpm. Let it run like that for a while. I always make sure that the temp gage needle moves noticeably into the "C" before doing anything besides slowly driving it to where I'm going to work. On very cold days I just let the tractor sit in the front of the house at 1500rpm, go in, have a coffee and start work after that. I actually plug in the block heater below 32F but there are many threads about that and warm up methods that people follow.

Idont start mine at idle ,but i never give it 1/2 throttle .Ido crack it open a bit [mabey 1/4] it does help it start right up.If i dont crack it ,i sometimes need to glow again.Idont like to many rpms at startup either as someone else said.
