My CK20 hst tends to stall on take off

I'm not sure what the manual says about break-in but here is my personal opinion for what it is worth: I have done numerous overhauls on a variety of size and color tractors and about the only thing that drives me batty is extended periods of idling in the break-in period. Mostly because the lubrication is at its lowest point and also there is lower heat buildup in the internals of the engine. This could possibly result in the rings not seating as well as they should resulting in increased oil consumption during the life of the engine. High rpms don't bother me one bit after the first couple of minutes after the overhaul.
My advice has always been break them in like you are going to use them.
Don't be afraid to rev up the engine. In fact, lugging is far harder on an engine than the high rpm's will ever be.
I think from reading your post you just need to rev up the tractor. From there it is a matter of learning how to put the power to the ground most effectively.

WOW !!
We seem to have the same opinion.
That is how I have always done my breakins..

My dealer told me the same thing. I had my tiller on mine as soon as I got it home and tilled for an hour or two. i'm at 65 hours now.

I have to agree with the running like you were using it... personally the only time mine idles is when I am doing service work on the tractor (zerks etc) or waiting for the temperature to come up to start using the machine. I think of it like I do my truck... I bought it too use if it breaks in the process I must be using it like it was meant to be used (not abusing it, normal items that break). Let me use a truck for example every new truck I buy I take off road through as many branches as I can the first week of owning it. Once that is complete I don't worry about getting a small scratch or dent after all it is a truck or a tractor in this case. My machines get washed and bathed regularly all general maintenance done (daily before use) with services at normal times. Past that use it like a tractor and give it a little gas get the juices flowing!!

I have had pretty good luck with the break ins as well. My 2000 F350 diesel has 163k on without any prblem in the complete drivetrain, my yanmar in the John deere has 2900 hours on it without any oil burn or problem at all. I guess we are doing the right things.

Was the problem solved? John

This thread is well-timed for me. When I bought my CK20HST recently, the dealer was a bit vague on break-in RPM. I've kept below 2500 for the few hours I've used it (on snow), and closer to 2200. But that definitely isn't enough power for the heavy dirt work that starts this weekend.

I thought of idling it for 20-30 hours. That wouldn't use much fuel, but still seems a waste. Is it really OK to crank it up to 2800 RPM, and fully load the loader and hoe, with only a few hours on the clock?

Also, is it better to hose the whole beast down each time, or let the dirt pile where it may? Any areas to avoid soaking?

Thanks-

I follow that same advice. Most people don't run their equipment hard enough. Hard to over rev these little diesels anyway. Unless going down hill with something heavy.

Not only would it be a waste, it would harm your engine. Just idling at the same speed is a bad thing to do. Most diesel trucks even have variable idlers on them now to avoid problems.
Use the tractor at 26 or 2700 RPM, or even full out if you want, just be careful to try not to let it lug way down a bunch.
Getting it up to operating temp and working it is what it needs to seat everything. John
