anyone ever run into a 718 grasshopper lawnmower with the 600d engine in it? just got one for free and it will turn over great but wont start sounds like it wants to but never does ive primed it it gets fuel i get white smoke jsut wont run i just bought the glowplugs and tonight when i get home im gonna try that.

when you turn the key over should i wait to start?  my question is should it have a first click in the switch to warm up plugs? because if thats the case when i turn switch to the first stage my glow pluge relay doesnt get andy juice to it but when i actually turn it all the way and while its cranking over my glowplug relay has 12v

It maybe that you turn the key backwards to get the glow plugs to work then the right way to spin the engine over. Does it sound like the engine is turning fast enough, they have to spin pretty fast to star. Does it have an electric fuel pump, if so is it coming on when you turn the key to run, you should be able to hear it. If it does, you can bleed the fuel lines all the way to the injector pump fuel inlet, then crack the injector lines loose to see if you are getting fuel to the injectors.

Hi,
I don't know how Grasshopper did their diesels, but Cub Cadets that used the 600D had a setup where you turned the key switch counterclockwise to energize the glow plug relay. You manually held it there for however long you needed it (10-30 sec)
before turning to start. It would make sense that the glow plug relay kept energized for a few seconds after engaging the starter.
imo, once the new glow plugs are installed, it will run!
Good luck.

Chuck

However they do it, there needs to be some way to pre heat before you turn the engine over. Try what was suggested above. The glow plugs can be tested with an ohm meter. Should read low ohms.

Old Kubotas always start hard.  They are cold natured.  Glow plug the heck out of them and they will fire right up.

 

Turn the key backwards for glow.  On is just ignition on, the glow plugs will not work, and start should have the glow plugs engaged, so it sounds like your wiring system is working just fine. 

 

I don't know how you managed to be in the right place at such a right time, but free for a diesel 'Hopper is not bad!

Yep, even my Kubota D1005 that came off a blacktop crack sealing machine used the CCW key for glow plugs.  It's now in "Hogzilla", and I retained all the original wiring system.

As stated above, Make darn sure your glow plugs are working or all your going to get is smoke. 

Good luck.

I am a heavy diesel mechanic and worked on couple 600D Kubota in the past. I got to ask couple questions first. When was the last time this engine ran? Was it run outa fuel? I have had trouble with these engines loosing the prim at the pump. It usally blows white smoke when attempting to start if air is in fuel.

Try loosening the fuel injector lines that run from pump to injectors. Loosen all a turn or two and crank the engine. Look for bubbles in the fuel that is coming out. If there is air keep cranking until bubbles stop, each will stop at a different time. Ones bubbles stop close that line. Once 2 lines are primed the engine will start. Then close the last one.

I would try this first if the machine been sitting
