DK45 Cab hydrostatic.

[dirtdevil911]

Ok we have 120 hours on our new DK45 cab that is hydrostatic. Its been in for her service at 50 hours with the dealer. As of late the tractor has been a little difficult to operate. I am sure it is just a small adjustment but I do not know where. I am a handy guy and don't really want to bother the dealer if it is a simple fix.

Problem is the tractor just started to be difficult at idle to go into gear. I find that if I just touch the forward peddle it will slip into gear easy. With out touching the peddle the Low,Med,High selector shifter has to be used with great force.

Once in gear even at idle the tractor wants to move in reverse on its own with out touching the peddle. Reverse with great power even at idle. If RPMs are up it will move quite well in reverse on it own. It all so seems to be able to go in reverse faster at full peddle then in forwards at full peddle at the same RPM.

To me it is in the hydrostatic peddle adjustments and I need to readjust for neutral. Can anyone walk me through it with pictures and very good descriptive writing?

Cheers Don.

For some reason your linkage is out of adjustment to say it on the simple side. You might find that there is something internal leaking to have your reverse activated with still having the rest of the transmission in neutral if the linkage is still adjusted correctly. I'd have it to a dealer if you can find that you have no dent linkages or out of place.

When the gear selector low,med,high is in neutral there is no movement at all.

It does kind of sound like the linkages for the reverse pedal is too short, perhaps one of the rods did get bent. If no damage, you could try lengthening the linkages by loosening the jam nuts and lengthening a shaft by a few turns. Just don't over do it and forget what adjustments you've made, you don't want to foul it up so badly you can't drive the tractor onto a trailer to get it to the dealer!

It might be just sticky pivot(s) on the pedal or linkage. Spray all the linkage with some type of good lubricant and work the pedal a few times with engine off then try it before adjusting any linkage.

SSdoxie I am with you on that. It needs to be something simple or that is needed to be adjusted after these are run for a bit. I am thinking that with out front fenders there is dirt up in that area from running the gravel road.

First, don't force it into gear, as you stated you need to do if you don't engage a f or r pedal first. Sounds like you need to inspect, clean and possibly lube before you do any linkage adjustments.
Check the areas under the tractor where something might have caught a linkage, like dirt, rock, stick, etc. Have someone move the range selector, ( H M L) through it's full range, with the engine OFF, while you check to see that it moves freely. There is a neutral lockout 'switch' under the range selector lever, which should not be hampering the range selector movements.
Personally I find my range selector may sometimes not want to go into a particular gear and I let off trying to force it and allow the tractor to coast a few inches forward or backward depending on where the tractor is inclined to want to go via gravity and then the selector will go right into gear, OR I can press one of the pedals and effect the same thing. Your situation sounds a little more complex because of the reverse movement, but not something that can't be solved fairly easily. Check what has been suggested to date and post back results. I also suggest buying a service manual.

The range selector works totally free when tractor is off. Nice and smooth. When tractor running is when it is difficult like the trans is getting pressure from the hydrostat controls. When just easy pressing the forward motion peddle the range selector move gear to gear smooth with the tractor running.

We will give her a good lube and look over and post back. I know 99% of the time trouble shooting is something very very simple.

Cheers Don.

Well my Kioti is all gears so I don't know nuthin about HST except what I've seen in the service manual. But it seems to me that the swash plate that drives the pump section of the HST isn't returning to the null position. As recall there has been a lot of chatter on this site (usually driving a little forward with no foot input). Reported fixes (as I recall) included everything from greased linkages to a new transmission.

IIRC, what you describe is a function of some CK, NOT DK Series Kiotis. I don't remember anyone having a major issue with DK's along the lines of what the OP stated were his symptoms. Obviously, I could be wrong... so if I am I'm sure others will chime in.

To the OP, the fact that so far the range selector works with the tractor off is a good first step in finding the actual issue. Keep looking...
And, after rereading your post, it seems you might need a slight pedal adjustment, if everything linkage wise turns out to be in order. Let's hope for the best.:thumbsup:
