What did you do on or to your LS Tractor today?

[GSVette]

Just to clear up what could be some confusion about the turbo failure. It had nothing to do with DPF regeneration. Rather it had to do with oil weight being to heavy and revving the motor to quickly after startup when it's really cold.

So the software will disable the throttle if ambient and coolant temperatures are within a set of parameters. It may also follow NH and recommend 0-40 oil.

That’s what I recall from the NH TSB. I reached out to LS after the NH oil issue was brought up and was told there was nothing from LS. Has the Spokane dealer given you a TSB reference?

Got the grill guard upgraded to hopefully keep the LS from getting a black eye.

Looks very good! That should help prevent some damage for sure!

I wonder if that has been addressed through start up procedures? My LS, purchased in Fall 2019, explicitly states to run the tractor at idle for at least 1 minute before raising RPMs to allow proper oil circulation to the turbo.

That very well could be that they did as you stated. Not sure if LS made software changes as well like New Holland did. Makes sense to limit operator error.

Watching egts it's just as important to idle for cool down as well in summer heat.

I should have mentioned in my original post, it does same the same about cool down. Bring it down to idle for at least a minute before turning off.

It's been my experience that it takes longer to cool down. For example, a 80 degree day mowing for hours will take mine about 5 minutes to cool down. That is parked with the AC off. The other day it was 1°F and it took about 1.5 minutes to cool.

I monitor the EGT probe through the obd port and I look for 350 degrees or less before I shut it off. So if you don't have a gauge I'd suggest letting it cool a bit longer.

My LS Dealer came out and did the software update that limits the throttle until the Turbo is sure to have oil. A 6 hour drive in a blizzard for a 5 minute update! That is a dedicated Dealer.

Good to know.

Can you provide a description/picture/explanation of how you did that? It seems to me that would be a very useful monitor/gauge to have. It is unclear to me how much a tractor really needs to "warm up" before operating. (We don't think anything about hopping in a car, cranking it over, and heading down the road at 50 mph).

Is it a couple minutes to get the oil flowing freely to the turbo, and then taking off? I hear of people running their tractors for 30 minutes to warm up on cold days, which doesn't make much sense to my (admittedly) ignorant self.

Having a quantitative measure of the engine temperature would be useful.

Your question on warm up will give you many answers. I will say where it's stored in the winter is the most important, outside is 10 below or in a heated shed. Idling for 30 minutes is just something I wouldn't do myself.

Here is a link to a picture of my monitor.
