CK20 wouldn\'t start

For anyone interested. I was cutting up some trees that blew over and was hauling them away with the tractor, I was on and off a few times, I was all done and standing talking to my neighbour who was helping, when I went to leave, the tractor just rolled over and over and wouldn't kick, the first thing I noticed that there was no white vapor coming out the exhaust which is usually an indication that there is no fuel present, so the first thing I suspected was the fuel shut off. Good guess, the solenoid didn't pop back out all the way to open up the fuel valve, must be getting sticky. I just flipped it the rest of the way out and away she went. First sign of any problem with my second most favorite baby (first grand daughter born two days ago became #1). My Kioti is now 14 months old with 160 hours now. Reliability is what I expected when I bought it and it hasn't let me down yet (knock on wood).

Congratulations on the grandkid, my first is 16 mos., they're a lot of fun.

Good to hear you fix that little problem so fast.. Congratulation on your #1 baby /forums/images/graemlins/blush.gif...cag

Re: CK20 wouldn\'t start

So you use the fuel shut-off valve to shut off the tractor.
I just use the key and it works fine. I assumed the fule shutoff valve was for emergency only.

Also were you shutting off and turning on the tractor constantly while you were "on and off" it all day. Diesels are made to idle and they love it. I would just kick down the rpms to low idle and leave it running. I don't think those fuel shut-off valves are made to be used so frequently.

Just a thought. Thanks for the info.

I have a new-ish CK20 also. Much of my work (OK, play) is moving huge piles of chips and dirt and smoothing them out. That's pretty steady. But when I'm pulling stumps, moving rocks and shrubs, etc. I'm often jumping on and off the machine. Sometimes it's 15-30 minutes between actions.

People here have expressed strong opinions about the OKness or not of long idling. Dealer says it's fine; others say that the engine doesn't like running at one speed for a long time.

Any way to get an authoritative opinion? Startup seems like more stress on the machine than idling. I also noticed in the book that the "hour" meter assumes 2200 RPM. So I guess it actually counts revolutions, and not minutes.

Re: CK20 wouldn\'t start

I have heard from many, many, many diesel mechanics that idling is not harmful to a diesel engine unless it is still in it's "break-in period" of 20-25 hours. This is when you do not want to leave the engine at the same rpm speed for a long period of time.

Startup is rough on a diesel, the air is cold and the whole idea behind these engines is that the air will heat up to a self combustable temp by being compressed and injected with a small amount of diesel fuel. Obviously, the colder the air = the furthur away from it's combustable point it is.

Tractor trailer drivers (long haul) leave their trucks idleing all night long for heat and to keep the engine warm while catching up on some sleep in a rest area.

It will not harm a diesel engine, primarily because of the more effective lubrication system.

Have I confused you yet ? /forums/images/graemlins/cool.gif

Re: CK20 wouldn\'t start

It's my understanding that most diesel trucks has variable idlers to avoid steady speed idle. Most of the folks I know say it's always best not to run for long periods of minimum idle because the lubrication is lessened, but that all out running in high idle is just fine. I don't really know for sure, but I try to vary it a little if I'm off the tractor for a while rather than let it stay at minimum idle the whole time. I figure it couldn't hurt to listen to the old timers that know more than I do. My previous experience had always been with gas.

Re: CK20 wouldn\'t start

Derek,
Your all over the map /forums/images/graemlins/grin.gif, I just use the key and it works fine. ,this is all I do to shut mine off.
Also were you shutting off and turning on the tractor constantly while you were "on and off" it all day. No, I was only on and off a few of times and usually don't shut it off, the last time I was off for a half hour or so and was talking so I shut it off to hear. Diesels are made to idle and they love it. I would just kick down the rpms to low idle and leave it running. I don't think those fuel shut-off valves are made to be used so frequently. I don't think they're made to idle, and yes, I do think the shut off valve is made to be the main shut off, if you look at the set up, both the solenoid and the pull cable are both attached to the fuel valve. My old Kubota of 18 years, well the only way to shut it off was to pull the cable to shut off the fuel. The kioti was made to energize the solenoid to close the fuel supply for 5 - 10 seconds after the key is shut off and then reopen the valve. One time I put my old Kubota away in her shed after plowing snow about 1:30 in the morning and went to the garage to get something, got side tracked and ended up in bed (comments inserted here). Went outside the next morning and thought I could here something running. Well I guess long periods of idling is not a detriment to any motor. As far as knocking it back to an idle, mine just about always does go back to an idle as I have a gear version of the CK20 and use the foot throttle to control my speed and hydraulic functions. Also most of the trucks in the company I work for (probably a half dozen or more of the long haul ones) have an auxillary diesel heater for heat when bedded down for the night, they are much more efficient then running a truck at idle for extended periods of time. Have you seen any of the newer trucks with sleepers, I mean homes built on them, double bed, fridge, microwave, fold down tables, i could go on and on (well I guess I am). Thanks for your time and patience.

Re: CK20 wouldn\'t start

Is the pull knob to shut down the tractor a fuel shut off or a compression release?? I have a Yanmar 3GM motor in a boat where the shut off is clearly a compression release system. Is that not the case with the Kioti? (Sorry I cannot check mine as it is 80 miles away).

I use the pull knob rather than the key based on habits formed from boating. Only problem is sometimes you forget to shut the ignition off.

Re: CK20 wouldn\'t start

The pull is for fuel shut off, at least it is on mine. The compression release is not hooked to anything on mine, it maybe on yours, not sure. Next time you see the tractor flip the hood and you should see the compression lever at the end of the valve cover next to the firewall. There two pulls side by side, one is the fuel shut off the other is flashers.
