That is an instruction manual better than any I have seen. Thanks for sharing that.

I tried to crank it and it would not start. We did all the things needed when running a diesel out of fuel but it would not crank and would run the battery down real fast. My buddy a a diesel truck mechanic worked on it and could not get it cranked.

Crank does not mean start. To crank an engine is to turn it over. You mention having it in "N" when towing. Do you mean the HST lever was in "N" or was the HST disconnected from the drive train..

A hydrostatic transmission is basically a closed circuit hydraulic system. A variable displacement pump feeds a fixed displacement motor. Usually they then go to a gear transmission although they can be direct drive. Some have a disconnect so unit can be pushed or towed. Four wheel drive is usually taken off the transmission after the hydro, and is disconnect able
When a hydro is towed there are bad things that happen.
1. the hydro gets no lubrication. Lubrication is done by the input or a charge pump. No lubrication destroys transmission, as metal seals against meta.
2The motor forces oil into the pump, usually blowing the relief valve causing heat. also why a hydro doesn't push
3. towing too fast causes parts to spin too fast, which causes excessive wear and damage.

Thanks for the info, I only towed it 1/10 of a mile or less ant 5-8mph or less. I was leaving to go work on the road and let it sit for about a year, when I tried and crank It would not start so my buddy who is a diesel mechanic came over and still couldn't get it started so he was going to take it to his shop when we went to load it on my trailer we found the wheels where locked up and would not roll. I thought the brakes were locked up from sitting so long. But after he couldn't get it running he talked to someone he works with that said if we towed it we damaged the trans and that is why the wheels were locked up.

There is a lot of "guessing" going on here
The OP did not mention if the Range shifter was in Neutral or not -- need clarification on this point

if the shifter was in neutral, there should be no problems with the tractor, for that short distance

if the shifter was left in gear before towing, then the HST is toast -- but only on the motor side
that means the pump side should still turn freely, and the "dragging" problem is elsewhere

Thanks, the range shifter was in Neutral when we towed it.

I don't know what you mean, if the HST lever is the forward / reverse lever then yes it was in "N"
Thanks

Here's the deal. The rear swash plate is still at an angle so when you rotate the drivetrain the driven angled swashplate pumps oil to a drive swashplate that is setting at 0 deg. I dont know what happens to the system but I think you better get it to a shop that knows HST.

I dont understand what this has to do with the engine starting but if your observation is correct ie.the trans seems to be engaged, then I think that further argues to get it to somene who knows about this HST.

That "N" does not disconnect the drive train It only sets the HST so it does not drive the output.

Buddy of mine had this same problem from an older JD compact with HST. Yanmar engine but same basic design as the Kioti diesel engines. Mechanical injection. We determined it was a fuel issue and replaced the lift pump, since even manual actuation of the shutoff didn't help and we kept getting air in the lines. Replaced pump and had the same problem with new lift pump. Actually worse. Chased our tails for an hour or so, then went to pull lift pump off to inspect and the plastic broke in half where the hose connects. Brand new pump was bad. If the starter is turning the engine, the glow plugs are working, and it still will not start, it's got to be fuel. Look at your filter, fuel shutoff solenoid and lift pump. Make sure all those things are working before you tear the machine in half.

Your locked wheel is likely a different issue. Sitting for a year I would suspect a brake hanging up. I'd be very surprised to hear that you damaged the transmission by towing it in neutral at walking speeds for a couple hundred yards.

I would think if the range selector (L/M/H/neutral) was not in neutral it was towed in gear and could damage the HST..

The owners manual on my chevy pickup tells me to put the transmission (automatic) in park and the transfer case in neutral to tow it. I've pulled it many miles that way. However, somewhere through your thread you started calling it a tractor, so I guess I'm confused as to what we're dealing with here.

He called it a tractor because it is a tractor......A Kioti CK2500 not a Chevy 2500 pick up truck......

That was easy, Thanks

The locked wheel is most likely related to my discussion regarding swash plates.

 

[MHarryE]

To be clear, is this a Kioti CK25 tractor? You say CK2500 and I don't recognize that model except as a Chevrolet pickup or Kobelco excavator. If it is the Kioti tractor, hydro version, you have 3 speed ranged with a neutral between - Low - N - Mid - N - and Hi. The tractor can be towed if the range selector is in either of the N positions. If it wasn't, and you towed it at 5mph, the tires should have been sliding on the ground.

 

[John Liebermann]

MHarry, well that sure negates my xplation. Sorry to the group for misleading. I assumed this was a hydrostatic. That's what assume does

After talking to a shop and reading all these comments I am going to work on it my self, to see if I can get it running or not. Thanks for your help and I will update when I have something to ask or tell.

The tire were not sliding so it must have been in N, It's been a long time now and I was in a big hurry that day but I do know to put anything in N before towing so I assumed I did.
Thanks and I will post when I have something.

Pictures of the carnage when you find the problem

 

[MHarryE]

On March 14 you wrote your buddy said the rear wheels were locked when he tried putting it on a trailer. This would happen if the hydro was in Hi, Mid, or Lo range. If in either of the 2 "N" positions, the tractor should have rolled onto the trailer.

I have looked at the transmission drawing for I hope to be your model and my assumption is that the short distance shouldn't have damaged any of the transmission components, the only parts rotating were the final drives, the crown and pinion that also carries the low, intermediate and high speed slider range gears and seeing that the tractor was in neutral whilst being towed, the parts would have been sitting in oil and would have self lubricated, the HST is independent of the transmission drive until a range slider gear is engaged with the cluster gear, and then the whole shebang rotates.

It has only come to notice that the rear wheel dragged whilst being loaded on a trailer after the tractor sat for 12 months, I feel that the brakes have locked up to cause this.

And the heavy turning of the motor, I wonder if the tractor was out in the weather and ingested some water into the cylinders to cause hydraulic lock.

DavJ82-- I would consider thinking about removing the starter motor and using a large flat blade screw driver or tyre lever and try turning the engine in direction of rotation checking to see if there is a resistance, also did you push the clutch pedal in when trying to start, this would relieve transmission drag.

Another suggestion would be to pull the injectors and spin the engine to blow out any fluid before you get into the transmission, only if the tractor was out in the weather.

 

[FredM]

Have a look at the drawing and see if I make sense, the pinion shaft is splined for most of its length to allow the sliders to shift for engagement.
