LX2610 glow plug timing discrepancy.

[mrrlyoung]

Several of us drive our LX2610. I hit the glow plugs for a few seconds at just above freezing when starting, as stipulated in the manual. One of us says the dealer said to heat them for up to a minute. A few seconds works for me, and a minute seems too long. Can the glow plugs be damaged if heated for too long? Seems like we have conflicting instructions. Any advice would be helpful. Thanks.

Yes, you can burn out a glow plug if powered for too long. Since day one, I've used 4 or 5 'steamboats' to preheat my BX23S, It's always started nicely. 5 years ago I changed to 5 flashes of the 4way signals, as they're always on when key is on.
technically you need more glow plug time the colder it is, as the block sucks away the heat, but yeesh a MINUTE ? Sounds like the dealer doesn't OWN and USE what he sells.

Go by what your manual says. The dealer doesn't have a clue what the hell he is talking about....or he wants to sell some glow plugs.

Old Kubota's needed a minute but none of the Kubota's in the last 30+ years need to be heated that long.
It really had nothing to do with how long it takes to heat the plugs, they heat within seconds, it had to do with how long it took to heat the space the plugs were in.
Old head designs used a large prechamber and had poor heat transfer thus it needed a long preheat time.

I use about 5 Mississippi's year round here in Central Oregon. 80F or 0F, don't matter. Starts right up.

I use about 5 seconds, and only when the temperature is near freezing. When it gets down to the single digits or less (F) I plug in the block heater for a half hour or so before starting.

Am I right that once the tractor has started and is running the glow plugs are completely out of the picture. They get juice only for pre-heating prior to starting and at no other time?

doesn't the LX#### have a dash light (glow plug indicator) that goes off when glow plugs have done their job and computer tells you its time to hit the starter?

if you hold the heater on longer than needed then the computer cycles it on / off? (or at least the light cycles on/off)

 

[mrrlyoung]

I think ours just has the glow plug heating light on when you hold the switch to that position. I don't think there is anything designed to monitor the plugs' temperature. I'll double check. My assumption is that when the 'heating' lamp is on they are being heated, otherwise they aren't, but they will keep heating as long as you home the switch.

The glow plugs have power in two positions of the key. In preheat position the glow plugs are powered. In the start (cranking) position the glow plugs are powered.

But when in the run position the glow plugs do not get any power (unless there is some sort of electrical malfunction).

Your first statement is true, the second is generally accurate but not 100% true but that is really nit picking!

Thanks. That makes sense.

They have the dash light indicator, but it will stay on for as long as you have the key in that position.

got it... on my L the light goes out (quickly when warm and when -30 it takes much longer) when preheat done and then hit the starter to go.

thanks

Between 4 and 7'mississippi' for me, depending on the temp.

In the cold weather (<40f), I also try to plug in the block heater for about an hour, as a general rule.
