I got a similar model Kubota, and my indicator went out 3 years ago, and my plugs still work, only thing that indicator does is tell you the plugs are hot...
I have a Kubota B7100 and love it. It is a 1996 Model, HST, 4X4. 2200 hours. I have owned it 10+ years and it has been mainly trouble free. It had been missing some when I first start it but quickly smoothed out. However I went to start it a couple of days ago and it wouldn't fire a lick. Just a lot of dark grey smoke coming out. However when I keep cranking it for 15-20 sec it went ahead and finally started. But shut it off and try to start it again and it was the same thing. I've learned a lot about glow plugs watching your videos. I'm going to replace the glow plugs (Amazon $9.00 each), and the controller. Someone told me there might be a fuse on the B7100 just for the glow plugs. Do you know if there is one where it would be.
My Ford lost the coil years ago. I just stretched out the remaining wire, and reconnected. It still glows a little, but faintly. I do about a 30 count in my head, then start.
Daniel I think shes loosing some compression, If I were you Id change the injector nozzles, do a compression test, and do a valve adjustment, the valves might be to tight letting compression escape. If you get a feeler gauge and loosen them up it might get you just enough compression to help it start even better. Just a tip.
It's a trade off between not ruining your battery/starter or keeping heat in the cylinders generated by compression which is what it needs to start. Most people will just keep cranking to keep the heat in it, especially if it's really cold. He was lucky it was a warm day and it started fairly quickly =)
I also noticed that you have 3 gages located on the lower left of the 'dash'. May I ask what those are for and did you add them yourself? I've been wanting to find some way of adding a heat gage to to my B7100 but haven't figured it out yet.
Too bad your glowplug system failed like that. My 1982 John Deere 650 (16hp 2cylinder yanmar) has no glowplugs at all. It just has thermostart which warms the intake a little by burning some diesel fuel in the intake manifold and thats all it does. I have no block heater on it and it will start without preheating almost instantly in most any weather 50deg F and above. below 50 requires me to preheat for 20 sec. but it always starts knock on wood
diesels dont really need them. as long on they are warm its no big deal. hell, at one time they never had them. but you had hot bulbs and gasoline engines that could be switched over to diesel once it warmed up. R/C diesel engines never needed them, all you had was a little compression knob on top of the cylinder.
my kubota is 24 years old it has over 3000 hours on it. my uncle bought it new 5 years ago I bought it off him.I've known the tractor since it was brand new. it has never once used glow plugs, not once. it could be 0 outside its fires up every time without glow plugs. once diesel engine get used to them they need them just like starting fluid once you start you always have to use it. so diesels do not need glow plugs to start it just depends on how they are treated. people think they need them then the engine get used to it then very soon they have to have it.
This engine is a idi engine which usually means they have glow plugs and usually need a glow. Di engines do not have glow plugs and fire without any pre heat
You are implying an engine has a tendency to form habits. That's just not how it works. Diesels need 3 things to run. Fuel, compression, heat. A healthy engine provides 2 of the 3, a GP or intake heater provides the 3rd. They can be started without glow plugs but cranking times are extended plain and simple. This taxes the battery and starter. Perhaps not a big deal if everything is in good condition. I place the largest possible battery in my 275 plus I added larger cables. The best thing you can do for a diesel in cold weather - not 75* weather but COLD weather - is provide the biggest battery possible. Faster longer cranking speeds is the best way to build heat within the engine without using glow plugs or grid heaters.
That might need a engine rebuild because i have a yammar ym186 from 1980 and when is is 60 degrees out it starts in like 2 seconds

Damn, didn't know that was possible, I knew once started the glow plugs aren't needed, but I didn't know you could start without them
That looks exactly like by B7100. What FEL was that? I would like to purchase one for my unit.
yep....just keep winding...or maybe just replace the glow plug indicator..??...only question of time till you bugger the starter motor..:)
Hey the best way to start a diesel with no glow plugs it to crank a little bit stop, crank some more, stop, repeat till started,

Good thing it was 70 degrees when you needed it lol
Kubota B2650 much older than this;
So why would Glow Plug need a "controller" *???*
Only crank it like 5 seconds at I time, I think it lets the diesel drop on the rings there for boosting compression
Cool thanks for posting.

Until you can do the proper repair, jump the glow plug buss with 12v positive battery for a few seconds, should fire up.

Lol
just bypass the thing they are useless ...
