My NX6010

1. ) I informed my dealer of the slipping out of med range . He said he would bring it up at the dealer show coming up.

2.) Today clearing snow there was about 3X that the tractor acted like it was in neutral and wouldn't move F or R. Was in M and the instrument panel showed M range but wouldn't move. After about 30 seconds of fiddling around it took off. Dunno

3.) Does your tractor defrost work very well and do you have any solutions to lots of fogging. Only thing I have done is put a big roll of paper towels next to the seat and it's a constant cleaning action and it's still not great..solutions? (Have set on outside air)

3) Turn the a/c on with the heat. It will dry the air and keep the glass clean.

Will try the A/C trick next time.

I have always pressed the forward pedal slightly to coax it into gear. My dealer told me to do that when I had my CK35...now I do it on my NX...

Although I have not looked in the service manual, typically in automotive applications, a temperature switch will not allow the AC clutch to run if is it below 32-35 degrees fahrenheit. I've grown tired to wiping fogged up windows and so I ordered a Frost Fighter defroster kit (1216-1725-L Clear View kit) for the rear window. If it works out well, I'll add defrosters to the doors as well.

The lack of defrosters was one of the things the Kioti lacked that I had counted on adding before I put the tractor into service, but I was getting family pressure about blowing the whole month of July, 2014 modding up the tractor, and so I didn't get around to knocking everything out that I had originally planned.

Comancheflight, call me crazy, but your point 2 made me wonder if this might also be related to hydraulic flow, rather than simply the range selector linkage. The same thing happened to me a few times as noted in post 1071, but on one of those occasions just raising and lowering the loader while pressing on the forward peddle, rather than fiddling with the range selector, the tractor started moving again, as if nothing had happened. This seemed odd, but I know very little about how the valving works on the NX series, so I report this only to add a data point. The other few times this has happened, I fiddled with the range selector rather than the joystick to get moving again.

Something else, while we're on the subject of range selection: Once in awhile I'll have trouble shifting from neutral into one of the three ranges, as others have occasionally reported on the NX and DK HSTs. No big deal, because I've just nursed either the forward or reverse pedal a moment or two and the selector slips into gear. In fact, I think this is common from time to time across other makes of HST tractors. It has worked for over 20 years with my Kubota B2150HST.

HOWEVER, last night I was going through the NX series owner's manual and came upon something in section 4-36 that I hadn't recalled focusing on. It says:

"Follow the instruction below if a problem occurs during shifting this [range selector] lever:

1. Put the range shift lever into the neutral position.
2. Depress the pedal slightly [doesn't say which pedal!] to prevent the gears in the transmission from rotating.
3. Shift the range shift lever into the desired position with the brake and front/rear driving pedals depressed."

Now I'm wondering what this section in the manual really means! Should we be depressing both the forward and reverse pedals simultaneously?? Is there yet another pedal involved, as well? What other pedal would "prevent the gears in the transmission from rotating"?

We're due for more snow tomorrow, so I'll try to get out and try some different things. I'm going to feel a bit silly if pressing both directional pedals simultaneously makes it easier to get into range.

Input from Eric, other NX and DK HST owners, in particular, and anyone else welcomed!

The technique is to hold the brake, and very genteelly press with the forward or reward HST pedal a little bit (as in a feathering motion, if you follow). The low-medium-high range selector gears are not synchronized and without blocker rings, the gears need to be aligned in order to shift.

Shifting wise, I haven't had my transmission jump out of gear since I aimed a video camera at the thing, but my tractor is getting warmer in the winter because I'm not starting and stopping all the time, I'm jumping in, starting it, allowing the oils to warm up a bit, selecting medium, plowing my driveway, then selecting high and driving 5 miles down the road to plow out my new parcel, and a neighbor. What is interesting is that even after plowing a 1/4 mile driveway, my hydraulic fluid is still not warmed up, as I bog down on a hill right past my driveway in high, then later on when coming home after several hours of running that same hill doesn't bog down my tractor in high.

As a result of thinking about how and when I've had the transition pop out of gear, I started to think it may be an oil problem or oil temperature problem. I am using the recommended Mobilfliud which I have enough on hand right now for my 400 hour service and so it will be awhile before I swap to a different hydro trans fluid.

What I can say is that when tractor has popped out of gear, the gear selector pops forward. As a result, I've never had it pop out of high gear. Also, when ever it has popped out of range, it has done so from a dead stop, while attempting to begin moving as the engine has revved up, and as the transmission is transferring the load, but hasn't really even begun to move yet.

I shared my thoughts with the service manager at my selling dealer about my temperature thesis, but nobody wants to mess with it until I can offer proof with a video because the dealer doesn't believe they can duplicate the issue in their parking lot.

My jumping out of gear was exactly as yours. Med range and jumps forward and always from a stop. My dealer actually asked those questions and said they would Check it out..I told them to wait till spring if it is still doing it. He said that was fine and he would report it to Kioti.
I also forgot about the temp A/C switch but excitement overcame.

I was just looking in the NX service manual and I couldn't find a dedicated AC low-ambient temperature cut-off switch, so try it. I know the light comes on, but I cannot hear the AC clutch kick in even in summer.

 

[comancheflight]

I will try it...I can't hear the clutch in summer either, nor any engine load..I did pop the hood and look at the clutch and it instantly kicks on. So worth a shot. Gonna clean the windows again although I cleaned them a few weeks ago using one of those thin cloths you put in hot water and wring out and use without any type of chemicals. I use them on my cars and they can be almost black from the stuff they remove and our vehicles never fog. (They used to before I bought these )..

Shaving cream keeps windows from fogging too.

Most (all?) cars use the AC in defrost setting to dry out the air before it is blown onto the windshield. That way it doesn't condense and make the fog on the windshield worse.
Generally, an AC system will have a high and low pressure cutout switch, but no ambient temperature switch (automatic systems in cars that choose when to run in recirc mode excepted).
