2 tractors here ... 2 different breeds and 2 manuals and 2 different suggestions for starting.
1.) Montana 4340 .. Put the hand throttle to the middle, after start run at 1500 RPM fpr 5 minutes.
2.) Branson 5530 ...Put the acceleration lever to minimum, after start 1500 rpm for 5 minutes
Until this thread I always started either one at a minimum and let them warm up at a minimum ... which is about 8/900 rpm.
NOW what to do????? I thought I understood this ... gotta go... need to call the shrink!!

Take two pills and call us in the morning 
, all kidding aside, I thought it was pretty common knowledge when it comes to a diesel engine, It's not that idling is bad, other than it waste fuel, but low idle and cold conditions is not a good thing, Any diesel engine will suffer from it when they run cold and fuel doesn't completely ignite. This is why you bump the RPMs up anytime the tractor is sitting in a cold environment 32 Fahrenheit and below. 1200 RPM is usually good enough to avoid the terrible wet stack. Take care

20% throttle on my TC and then leave it there to warm up for several minutes.
No matter what type of engine, the oil has to circulate well for long engine life.

Do what the manual suggests, 1/4 sounds good.
I've had several old diesels. V-8 Perkins and so on. As noted before, the old ones were 2/3 throttle(light dose of either if needed) until they were running good, than i'd leave 'em at 1/4 to warm up.

I agree with that 100%. Not because of pressure, but because you get some oil to everything before the combustion pressures kick in. As for running a cold motor at high speed to build up oil pressure faster that is a myth. Oil reduces friction because of the dynamics which cause the oil to form a supporting wedge and it has little to do with oil pump pressure. The tiny pressure provided by the oil pump is negligible compared to engine pressures.
Take it easy on a cold engine.

Well, crud, this thread made me go look up my Kubota's starting procedure, i.e. I read the manual
I've been starting mine with throttle set at idle, & never a problem, always starts in an instance ('course I'm in FL) ... But the manual says: "Set the throttle lever to about 1/2 way."
Who knew??

In all aspects we probably "baby" our tractors way more than needed and worry about all this stuff needlessly
My neighbor has a 2004 Tn55?? and it sits outside all year long. The oil might get changed every 300 hrs (if it's lucky)and in talking with him yesterday he has never changed the coolant since new and the tractor has 1700 hours on it.
When I asked him if he let's his tractor warm up he laughed and said as soon as it starts he puts it in gear and goes, winter or summer. His tractor looks like it has gone through a war-fenders dented, seat looks like 12 cats had a fight over it, faded out paint, lights on the rops broken off .
What's frustrating he has never had any service issues whatsoever while it seems the guys who baby their tractors, keep them indoors etc always have things going wrong....just doesn't seem right
Kinda like women I guess. The ones that get beaten stick around while the ones you treat like a queen (high maintenace types) end up leaving you. LOL

Keep in mind, alot of guys like that won't tell you if they did have problems, or they ignore the stuff they consider minor problems. If it starts, they call it good.
