Kioti CK3510SE HST - How The Hell Do I Engage the Locking Diff?

[seabumb]

LOL at this "read the manual" thread. I just took delivery of a CK3510 SE and it will not run for more than 30 seconds. So, I READ the manual, front to back, but sadly, no help. Now I have to email the dealer and hope they have a solution, but at least I can say, "I did read the manual".

Probably a waste of time to draw a distinction between understanding the functionality of the tractor's controls and troubleshooting an operational problem.

 

[seabumb]

RickB, I totally agree with you on that distinction. I was hoping the operating manual might tell me something like "open the fuel shutoff valve" which some tractors have (my Kubota) but that I could not see when visibly inspecting the tractor. No luck. But as is thread is pointing out, it never hurts to read the manual. I will say, I am very impressed with the detail of the Kioti manual. I have had three Kubota and the one TYM in the last 20 years and all the others just had a basic 8x11" thin manual with little detail, very few photos and more questions remaining than answered. This manual was refreshing.

Good luck with the machine. 30 seconds sounds like fuel delivery to me. Right to make dealer’s problem not yours

I'll give Kioti some credit for a decently printed and bound manual, but the contents... I've done a fair bit of reading in my manual and found a lot of things that are either missing, very vague, or flat out wrong. Seems to me they try to cover too many model variations with one printing.

You are right, but at least it is far better than the Kubota and the TYM 'pamplets'. Also great that this forum exists to kick us for the obvious or help us with what is neglected in all manuals.

lanolin based lubricant.'

Why lanolin? I worked with an engineer a while back who preferred it on O-rings.
Why not white lithium spray?

I have a 2021 CK3510SE HST. The darn diff lock lever below the left side of my seat feels stuck. It's been that way in the three months that I've owned the tractor. I've stepped on it, pushed on it by hand, tried it in gear, tried it in neutral and tried it after rocking back and forth a bit. NOTHING has worked! Am I doing something wrong? Maybe I have to hold my mouth just right. I don't want to haul the tractor 2-hours back to the dealer, so I'm hoping to sort this out on my own. Your suggestions are appreciated! THANKS!

I haven't been able to get min going either. Get a cramp when I try. Muscles not used to reaching back like that I guess. But it's stiffer than a sailor's member in a chinese brothel.

I honestly don't know as I've never heard of it or used it. I've just now 'Googled' it.

My Navy experience always went with the lanolin (or silicon grease or WD40).

The lanolin sprays, like Fluid Film, 'creep' into crevices and whatnot better. At least that is what they tell use when its used on airplanes - that it creeps into the overlaps, even 'uphill'.

I have a ck4010hst that the bar between the diff lock pedal and the actuator on the diff housing bent into a pretzel. I didn't stomp on it. Even driving in circles or having one tire slipping in the mud and applying pressure to the pedal would not engage it. Tractor is a 2018 with just over 100 hours.

 

[Raul-02]

I have discovered that slowly applying pressure to it while engaging the drive lets it slip in with less force.
Really this pedal thing is what I'd call god awful engineering. I'd prefer an actuator that I had to disengage when I wanted the slip.
You can find modifications online where people put a proper pedal there.

I have a 4210 Kioti and my differential lock lever appeared to be stuck at first but I found it can be moved with a lot of effort. It doesn't move very far so I'm not sure if its really working. Haven't gotten into a situation where it is really needed yet. Its such a ridiculously small lever.

I was working the tractor yesterday and needed the diff lock. LOTS of force on the pedal got it to lock, but to unlock it I had to stick my shovel handle under the pedal and pry it up, even after 100 yards of driving swervy to let it pop out. Is something bent inside the trans? I have been hitting the shaft where it goes into the trans case with PB blaster twice a week for a few months now.

Not sure what model or year of your tractor….but is the transmission oil at the proper level? Has the oil ever been changed? Manual Diff locks work by applying pressure to the lever and it will engage as the gears begin to slip out of sinc with each other, due to tire traction differences. Disengagement occurs when pressure is taken off of the lever and the spring pulls it out of the gears as they begin to sinc with each other as traction becomes equal from side to side. A good lube will help…

Hmm.. My diff lock pops up as soon as I remove my foot and apply a bit of throttle pedal. Its my 4x4 that usually refuses to disengage, though its getting better. I think they just need to be used more to 'break them in'.

2018 CK4010HST. 130hrs on it, oil has not been changed but the filter change was done at 50hrs at the dealer when I bought it used. Oil level is correct in the trans.

It’s been over a year since I started this thread. I am happy to report that I have successfully used the diff-lock lever on numerous occasions to get out of a sticky situation. Still, I don’t like it. I like what it does for me, but not where it is or how it is shaped.

It is not intuitive to stick the back inch of my left boot onto a slightly protruding round, curved bar and have to hold it down while I need it. When my boot is wet or muddy, it wants to slip off that bar. I would have preferred an electronic engagement by a switch on the dash. I do understand, though, why they don’t provide that option because too many people would leave it switched on too much. Barring that, my next choice would be an actual pedal in the same that could be more easily be found and pressed with a slick boot heal.

Still, it’s a minor issue. This tractor has been a real work-horse for me. We have gotten a lot done together.
