Need advice on my kioti

[K man]

I need some advise on my CK 30 HST which is useless going up hills when on the road. I drive in 2wd and in H range but when I start to climb steep hills it bogs right down to the point that I have to stop half way to change to M range and even at that it is still bogs or creeps and if I go down to L range then it just crawls up the hill and takes for ever to get to top. Any advise on what to do to make it better for climbing or am I doing something wrong. I have had gear drive tractors before but none ever crawled up hill like this Kioti.

Are you letting up on the pedal as it bogs?

 

[YLee Kioti]

Do you have 4wd?

I've learned on the CK4010 that in H range any steep incline will slow it down and possibly bog.
H range is for highway use?
As I was taking large stumps to the transfer station there is a steep city drainage system. It is a short incline yet it would stall. Had to go into M range.

For most hydrostat tractors, high range isn't much good for any inclines. Even in Medium range in my dk45se hst can have trouble too if its fairly steep. In many ways this is better for the engine and transmission, as the relief valve is opening before too much stress in placed on them. Gear drives, for the most part, will power through until the engine stall out.

But, if you find that maybe medium range should be able to climb a little better compared to other HST tractors of same power, check your relief pressure and see if it is to spec. If it is set to low, you will certainly be overly limited. Be super sure not to set it above the mfg suggested setting though, for obvious reasons.

Yes, but does not seem to help probably because it is in H range. Even in M range I release the pedal a bit and it sort of picks up but not enough then when I go to L then it picks up but just crawls up the hill.

Yes, I have 4wd drive but it is in 2wd when on the road.

now you got me lol I know nothing about relief valve pressure that you mention. How do I check that? My tractor is up for service in the next month or so will get mechanic to look it over. Thanks.

I expected my backhoe would do better than it does climbing hills. I have to downshift to 3rd gear for any decent incline.

I understand that on gear drive that you have a H and L range with so many gears to choose from but HST you can only use the ranges and lucky mine has L M H most just have L H. I guess the more I use it the better I will understand the HST versus the Gear drives.

 

[prof fate]

H range isn't worth much (ck3510 here). I just shift into/out of ranges as needed - low or m for filling the loader, H to move to the dump spot and back to l or m when back at the pile.

Keeping revs up (2800) helps on the road in H range.

 

[wagne223]

Do you have the throttle set at maximum rpm?
As far as the lever will move, aka wide open throttle.

For maximum performance, HST drives need pressure, flow and cooling. Achieved by running the engine at maximum rated rpm.

I can see having it bog in H but not in M
H is only for low load travel.

 

[K man]

I only use H range on the road or up and down in fields etc. When working the loader I usually use L with engine revs up. When I snow blow depending on how much snow there is, I would normally blow in M on light snow and L on deep heavy snow. The machine works beautifully until you start going up and down hills.

 

[Lockport]

The 25, 30 and 35 are the same frames with different engines. At least they were. Even the 35 is only suited for H on level ground with maybe a mower hanging off the back in transport. Definitely the "H" is for highway. There's nothing wrong with your tractor. I typically leave mine in "M" unless doing loader work.

running the maths

30 HP should pull a 3000 pound tractor straight up about 300 feet in a minute.

Half that for "efficiency factor", and you might be looking at a reasonable rate of climb.

Just a reality check. Next time you seem to be going slowly, bring a stop watch and mark your elevations. ;-)

The backhoe is only 4 speed. It’s really only meant to move around. The backhoe is essentially an automatic transmission with manual push button shift.

that's what I was thinking too, there is a big loss of horsepower somewhere!.. it makes you wonder how that tractor could do any useful work, if it can't even climb a hill easily!..

I’ve used a CK25 which is the most underpowered machine I’ve ever used and it still beats what the op is describing. Either his hills are more like mountain atv trails or there’s something wrong. Maybe something simple like a parking brake. I’ve never found a hill on the road I couldn’t climb in high range. As far as what’s a typical roadway grade there’s some pretty steep hills around my place.

Once again you're completely WRONG. You seem to like to come on Kioti based threads and make ridiculous comments not based in reality. The OP makes a thread title, also not based in reality, and gives no proof of anything other than not understanding how to use his tractor effectively. A better thread title would have looked like this...' having difficulty going up steep hills- please advise'...
The OP's tractor can and I'm sure does do 'useful work' all the time. It's not done in H, though, as it's NOT intended/designed to do so in the wrong gear... This IS an example of operator error, at best.

To the OP, get it serviced and check the relief valve pressures, as already stated. And next time ask for help or advice rather than an inflammatory statement from someone who does not know his machine well enough to incorrectly label it 'useless'.

 

[mrutkaus]

That is completely normal, I remember when I first got my 1005 CK30HST that irritated me also, but it has absolutely nothing to do with anything, that's just the way it is geared; shift to 2nd. It's a workhorse, not a racehorse!

I agree it sounds normal if the hill is a decent incline. On flat road with just the loader and rear tires, starting from a stop in H, takes a little while to get up to full speed. It's not a race car. It's not even a minivan When bush hogging, I have one steep spot, and just the incline there really slows me down in M range.

This can be even more of a problem - esp in H range - if the operator just mashes the HST pedal to the floor expecting it will act like a car. It behaves exactly opposite and the pedal needs to be engaged lightly and then slowly pushed down incrementally further as speed and engine RPM pick up. It will "just go" if you mash it, just takes a long time to get up to speed that way and won't handle much of an incline that way.

Also agree with above re Radios1 - another fine demonstration of nothing useful to add to any discussion.....
