DK40SE Squeal When Moving in Reverse.

grsthegreat · Jun 10, 2011

Not sure if they use same parts or not..ill wait till my parts book gets here. All i know is my DK45 HST has 60 hours and no squeal. I do like this tractor more every day i use it.

The service and parts manual are all inclusive for the group of tractors. The only callout differences are the motors as far as I can tell. I also believe we have 2 squealers here on this thread that are DK45SE (dourobob, Kiotikarl) and DK50SE (cshollr) owners. Did I miss any others.

As for the factory assembly lines I don't know how they are organized. I could imagine that a box or pallet of bad or differing charge relief springs or spacers would only effect a small number of tractors close in manufacturing range. Its not the tractor this design is tried and true.

Funny how there is a small group of us with new tractors bought right around the same time with the exact same problem. Since this occurs within the first couple of hours and it takes and hour more to heat the fluid before the squel shows its self I can't belive something broke.

This smells of an out of spec part plain and simple. I have worked on several factor floors over my life. If Kioti's plants are anything like what I have seen it would be very easy for a box or 2 of DK30SE or CK20 springs to have ended up in the DK40/45/50SE line. I wonder which tractor has a charge relief setting of say 165 PSI maybe.

This is all speculation but this would not be the first time I have see something like it happen (not with tractors though).

First off let me say that i do not own a Kioti, i am in the market and was seriously considering a DK45 or 55 until this post, so i do not have any insight into their equiprment beyond whats on their website and i read here.

Tnewburn and Kattywumpus, Thank you for all of your hard work and tenacity in trying to find a solution; your insight and generosity in sharing information is what makes this forum such a great repository for everyone.

After reading this post it seems like this problem only effects the DK40, which is very interesting. In today's production environment most companies try to utilize the same parts on as many models as possible to reduce overhead. Has anyone compared the Hydralic systems on the 40 to the 45/50 so see if there are any simularities/differeces?
- Hydralic lines.
- Pump specs.
- Relief valves.
- Transmissions.
- Etc, Etc, Etc
there may be one small item in the DK40's that is a carryover from the smaller tractors that is the limiting factor causing the problem that they changed on the 45/50 and larger tractors.

I am still interested in the Kioti tractors but with the unsatisfactory response from the dealers and Corporate i am a little leary on purchasing one of their products. Other than the HST system how would you rate their tractors? Thanks again for your hard work.

Hi, Dave. I have a DK35SE HST which according to the manual is part of the DK35/40/45/50 family. It just turned over 60 hrs. It has exceeded my expectations and I can't think of anything I consider a deficiency.

I felt guilty purchasing the DK35 to replace my Kubota L245 DT which was in perfect shape and did everything I asked. However, the new tractor's improved stability, ease of use (HST instead of gear), and comfort immediately erased the guilt. I am 68 and am sure the new tractor will increase my ability to remain on an acreage longer.

I am not demeaning the L275, it is a great tractor and the new owner will be thrilled. I also considered a Kubota L3540 which closely compares to the DK series. I'm sure I would have been just as pleased with it.

Also, the HST system on my DK35 seems fine.

The DK35se is in fact quite a bit different than the 40/45/50 despite being part of that series. It presumably has different hydraulics as it has different hydraulic output. Not sure if the HST is the same or not.

That's an easy one. It seems to be a very small number of tractors with this specific problem. Get it in writing from the dealer that is a squeal develops you get a repacememt tractor until yours is fixed no matter how long it takes. Not all dealers would agree to that, but mine would and I am sure lot's of others would too.

My DK40SE Hydro is around 3 years old and quickly coming up on 500 hrs(now that hay season is here). It has done more than I expected and things that I broke or lost due to "operator error"(a complete set of tail light housings, a rad fan, a bunch of oem pins & clips) were very reasonable to fix/replace. I run my tractor hard, my pastures are rough as heck(on the tractor and my kidneys), but I keep on top of maintnance and all fluids are full synthetic(except hydro fluid).

Coyote, as an independent observer of this thread, I would have to agree with Tom that it has been your aggressive and inappropriate badgering that is the problem. Tom owes you no further detail than he feels comfortable posting. It was your nastygram that was out of line a few days ago and Tom reasonably did not like it. I can understand you want answers however I suggest you save your demands and pontificating for Kioti management.

IslandTractor, Feel free to observe all you want, but until you have a squeal like those of us who do have you will not likely understand what it is like to put up with it. Agree with whomever you choose to. My way of managing drawing out more information from those who seem to have it, and want to share it when they feel is the right time according to their own agendas, may not suit your way of doing things; to which I say, to each their own.
Nastygram, that's cute, a twist on Blazing Saddles.

Yes, I'm trying to get answers, as well as let people who view this thread know that if they are considering buying a DK-40 series Kioti tractor that they may want to know what is going on in terms of this particular problem and Kioti's corporate response, or in this case their lack thereof.

As most who read the Kioti owner's threads on a regular basis know I'm on my second Kioti tractor in less than a year; and I fully respect the sturdiness of the tractors and their engineering savvy with a few exceptions. I would not have bought either Kioti if I did not feel they were well made. I switched from the DK-35 to the 40 for the benefits of the stronger loader, and its quite a bit higher lift capacity; and having 4 instead of 3 cylinders etc.

As to pontificating, I suspect it is a subject you are familiar with from your own posts.

Now, can we all get back to trying to solve the problem?!

Here's something I just thought of to contribute to fixing the problem.
Could everyone who has the squeal noise occurring in their tractor regardless of whether it is a DK-40, 45, 50 please post their tractor's serial numbers so we can see if there is any useful info that might come from where the numbers are in relation to sequence, etc. I will give mine to start;
JT6500016 As I remember it being decoded it was built in Jan of '10 and was tractor # 16 of that day's production.

Excellent idea...

KH1500038

The Service Manual states the first letter is year of manufacture.

H = 2008
I = 2009
J = 2010
K = 2011

Next 3 are the model number.

T65 = DK40
T66 = DK45
S28 = DK50

The remainder is the serial number.

I guess H15 is the DK40(C). So I would decode this as the 38th DK40C made in 2011. Thats strange I received it in November of 2010. I know this came directly from NC it was never on the dealers lot.

Possibly Kioti does what many car manufacturers do: they start the 'new year model' in Sept. or some other arbitrary cut off date- for their own reasons, usually to get a jump on the next year's production...

Update: Spoke with my selling dealer today and asked about what the status is on the squeal issue. He says Kioti knows about it and they have the transmission manufacturer in Scandinavia working on the problem. He further says Kioti will NOT tear apart a bunch of transmissions to find the cause only to find whatever it may be thought to be is not really the problem. Once they find the actual cause and effect they will fix the problem. He said further, the various bolts with taper or not is known by them, and has been for quite some time, and it will not solve the issue.

I asked why people who have had zone reps come to see their tractors are being told it never happened when speaking to Kioti corporate. He says they don't want anyone to know about it.
He says further that we are covered for four(4) years on the internals of the engine and transmission, so what Kioti is seeking from us is patience while they look for the cause and fix it.

Please remember, I only report the news, I don't create it. And I'm not saying what I'm told makes any sense one way or the other. Its just info- use as you see fit.

CM out.

Almost bought a DK 40 and would have if the dealer would have ever got back to me. I called 4 times. Went to the dealership and still no quote. Bought a Mahindra instead.
