CK20S HST - Hi SUX!

[crabjoe]

Today I went out to move a bit of dirt; then went well. Then when I went to bring the tractor up the hill in high, the thing wouldn't move. Fact is, it stalled.

I brought the tractor back to the house in Hi and decided to see if it would move in Hi on relative flat ground. I'm taking about 4 to 6 inches of drop for 20 feet. It was a NO go. The CK20s HST TLB is a DOG in Hi range. In low, I have no problems with it.

Now, can someone tell me if they run into the same issue with the CK20 HST TLB? It kind of sux to think that I can only use Hi driving around on level ground.

That slush-pump drive eats a lot of HP

how many hours on machine?
They are a bit low on power in high, but usually once engine is broken it they work ok. Also be sure your fuel filter is clean, any restriction could make the problem a big problem.

=====================

Stalled! On a grade pitching 4-5" in 20'? No Way......are you sure the Parking brake wasn't set? It's easy to leave it on.

It definitely will put out more hp as it gets broken in. I can climb some pretty decent slopes in high gear, it all depends on rpms. I have 320 hrs so it's pretty broken in and whenever working/traveling in high gear, I run it at about 2800 rpms.

after reading your post I thought I would go give my CK20hst a shot in high range up the drive way. I didnt have a bit of trouble and it would accelerate the more I pushed the pedal. I all I have on mine is the FEL rear grader blade and the tires are loaded. Attached is a pic of my driveway.

It will gain more power as it breaks in.

Were you flooring the HST pedal? HST responds differently than a regular gas pedal. Flooring a HST pedal can mean less not more.

I had same problem with my new holland tc 21d in high. It won't pull a slight grade in high but will not think about stalling in low. My backyard is about 15 degrees and low gear it is for me.

I am at 8800 feet, dont have that problem. I can pull my driveway in Hi and it is about 10%. Now moving snow or something its low 4wd all the time.

The tractor has 5 hours on it and I don't see it getting any stronger. The 1st time, I stepped on it like I was in low. When it stalled, I tried to feather it. The dang thing ain't moving in Hi, up any grade.

Oh.. I did check to make sure I didn't have the parking brake on. That was the 1st thing I did when it stalled. And from what others have posted, I'm now wondering if my parking brake might be stuck on.

How does one check the brakes on a tractor? Does this thing have 4 wheel drums, discs or what???

We're talking 50 hours to break in, and maybe another 50 to get to full power.

I loved my CK20 but high range was a joke. Looks like it still is even with the 20S. I don't believe this is a engine break in issue. My CK20 had trouble in high range from the beginning and still did at 180hrs. It works fine with no load on very slight inclines but is useless with a BH or other load on anything but pancake flat roads.

It is time Kioti put a three range HST in this puppy before the Kubota marketing machine neutralizes Kioti's other advantages and cleans their clocks with the new B series machines. A three range or at the very least a lower high range would do the trick. I doubt there are many people driving 20hp CUTs along highways so whether they need a real high range is questionable. A range equivalent to Low and Mid would be much preferable for most users IMO.

There are several that responded to the thread that say, they have no problem with high gear. So.......perhaps there might be an actual transmission issue with Crabjoe's 20s tractor.

I wonder if it's just setup different from the dealer. Maybe there is a way to turn up the hydraulic pressure or crank up the hp just a few to help out. Either way, I know my dealer setup everything exactly the way it should be with the extra add-ons (grill guards, larger buckets, etc...) and I wouldn't doubt if they adjusted something so that this problem is lessened.

I would love a three speed range, I could use a higher HIGH gear since I do travel quite a bit down the highway to my sisters place one mile down the road. Surely not worth trailering it short distances.

I have loaded industrial tires, FEL, BH and a full metal cab and have no problem climbing hills and working on some. It's not a design problem, it must be the setup.

This is a "hill" that I could not climb with an unloaded (empty FEL, raised rake on 3pt) CK20 in high range. One photo looks up hill and the other down. I don't know the exact slope but it isn't really much. It may drop 30 ft over 900ft (I'm not talking about the very bottom which is steep).

I agree that 3 ranges would be better than losing high range completely but if I had my choice, I'd give up high for a mid range setting.

I've got about a 15ft drop over 200 ft, but it's not a consistent drop down. I tested it where, I know, it looks almost level and I could stall my tractor out in HI.

HI is useless for me, right now, unless I'm going down grade.

I don't have a CK20, but in it's defense with a TLB setup on a Kioti, you are moving quite a bit of weight with only 20 hp. With the right gearing you can get quite a bit of work done with 20 hp, but it won't do what a DK65 will do. Most all mowers now have more than 20 hp. Twenty hp really isn't much power when you have relatively high gearing and some weight. I just wonder if the gearing in high range with the TLB setup isn't just asking too much out of a 20 hp engine with the heavy Kioti.

It sounds like there isn't sufficient hydraulic pressure in high gear. Like Dmace said, there may be an adjustment that needs to be made to increase the pressure in the drive. What RPM are you running it at to go up the hill? Just checking. Or maybe it's just starving for fluid. Check the hydraulic tank. If the take up screen (or whatever is in there) is plugged, that could be limiting the flow. That sounds like something easy to check, I hope it is. I only know enough to be dangerous, but I'll put my money on a restriction in the hydraulic system. I believe the engine does get stronger after it's broken in a bit, but I don't think it gets strong enough to go from where you are now (only going down hills in HI) to where you want to be (charging up hills in HI). I hope you'll keep us up to date. Whatever you find out could be very useful to someone else in the future.

Precisely.
