I store my 4100 in my garage, the garage is insulated and thus it never gets very cold ">30 deg". How long should I let my tractor warm-up before I get going?

thanks

I usually wait until I see the needle start to move on the temp guage. You could hold your hand on the water jacket and start working it when it starts to get a little uncomfortable to the touch. By then the pistons are good and toasty and the oil ought to be warm enough to flow well.

Bgott, Thanks, that is what I thought.

Nuru,

Since the 4100 has nothing but idiot lights, you just have to let it idle at a half trottle of a few minutes. Mine just puts out a some smoke for the first few seconds and with the typical diesel rattles and shakes.

Just yesterday, I fired my up and it rattled and shook and whined for a few minutes. I let it run for a minute or two in the shed, backed in out into the garden area, and let it sit for about 5 minutes. The HST squeeled and the power steering whined. After a minute or two, the noises were normal.

Think about it, don't you whine and squeel and feel a little tight when you start up on a cold, winter morning!! /w3tcompact/icons/wink.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/smile.gif

The manual for my JD 670 (Yanmar produced) says to idle at 1100-1200 RPM for about 5 minutes. This applies during warm and cold weather.
My tractor is also garage kept...so I can't idle inside (the garage is in the basement). After about 30 seconds, I move my 670 outside for a few more minutes of idling.
Normally, after 5 minutes or so (long enough for a cigaret), we're ready to work.

However, even being garage kept, I'm still going to install a block heater. I've owned diesel pick ups...the ease of starting is just so nice...you know you're extending the life of the engine.

The 4100 also has glow plugs installed to aid cold starting. This information is not mentioned in the owner's manual but is in the TM.

By turning the key switch to the RUN postion it energizes a timer controlled 3 sec preheat cycle. Repeating the sequence over several times preheats the pre-combustion chamber to enhance fuel ignition during cold weather starts. Less smoke and noise on startup.

I check fluids first, then start and run her around 1300 RPM while I grease my FEL then clean hands.I then feel the oil filter, and if she feels warm, I take her for a slow lap around the yard before I get into any serious work. My 750 has to-late lights too, not gauges.On cold mornings, I turn my key CCW for 10 seconds first (glow plugs for preheat).

DFB,

I was wondering about having glowplugs in the 4100. You answered my question. Thank you.

Yesterday, when I started it, I turned the key to the run position for a couple of seconds and then hit the starter. Fired right up with no hesitation.

About the tecnical manual, what other kinds of info are provided. What other manuals do you recommend?

Terry, the JD tech manual for the machine covers a lot of ground. It details component location and theory of operation, along with troubleshooting charts, diagnostic test proceedures,and covers adjustments & repair. Once before I commented on how I thought it was one of better shop repair manuals I have. Well written and easy to understand. Couple that with the parts manual and you'll know your machine inside and out.

JOHN DEERE is well noted for their literature. A lot of it is AG oriented and relates to larger tractors and farm machinery, but there is also info for compacts and lawn tractors too! The list of available publications can be found at their web site. If you or anyone else is interested in them here's a link; Manuals & Publications

I park my JD 4100 in my basement garage. I found that a sump pump discharge kit - 25 ft. of plastic 1 1/4" hose and a slip in adapter to 1 1/2 NPT - for about $7 will slip right over the exhaust. I run that outside, start the tractor and let it run for about a minute (I haven't tried to see how long it takes to melt the adapter /w3tcompact/icons/blush.gif) and drive it carefully outside for the rest of the warmup. I leave the hose on until I get it outside, unless it looks like I might run over it or it pulls off. I still have to work on that and a permanent through-the-wall connection. It seems to work quite well, especially in getting rid of the heavy starting smoke. I have a small squirrel cage blower I have thought of incorporating, but haven't tried that yet. This whole thing is somewhat inspired by the exhaust evacuation systems in some fire stations.
