LB1914 Grinding when shift into reverse

[Missouri Kioti]

hey all, got a Kioti LB1914 about 600hrs. For a while now, sometimes when I would shift into reverse, when I would let out on the clutch the gears would grind Usually I would shift it back into neutral or forward, then shift back into reverse and it would work. But lately it has suddenly gotten much worse, to the point I have tried to not position the tractor where I would have to back up, which obviously isn't feasible with normal use. And now sometines it does the same thing when shifting it into forward. And yes I always come to a full stop before shifting.

been trying to research this, have read on other sites for peoples suggestions for similar described issues, but opinions seem to be all over the board. but several things I read people said it could need the clutch adjusted. I have searched everywhere, but I cannot find any article or even a video that shows how to adjust the clutch on this thing. Does anybody have any information on how to adjust the clutch on a lb1914?

And if it's not the clutch, does anybody have any other suggestions of what it could be?

I have done all the maintenance to the Tractor for the past 5 years. Always changed all the filters, fluids, grease, belts etc. Getting close to time to change hydro fluid again.

Also ever since I bought this tractor, the shifter to change it from high gear to low gear is extremely hard to move. I have to get off the tractor and use both hands and even then sometimes I have to use my fist to beat the lever in order to get it to move from high to low or low to high . have used lubricant which helped some but it's still very difficult to move. I don't know why this would be normal as I have read some people basicly stating such... but is it??

Any input is appreciated

It appears to be a shift linkage adjustment issue, perhaps the linkage may not be fully engaging the gears. It may be somewhat related to the high range to low range shifting difficulty.
Does the engagement point of the clutch feel normal, or has there been a change? The clutch may not be fully disengaging due to need for adjustment or an issue with the release mechanism or release bearing.

Thanks for the Replies! Here's the Update... I got some time today and took a look at the clutch linkage, was pretty self explanatory on adjusting it. I did find the clutch adjustment specs, the amount of free play in the pedal was supposed to be between 0.8" and 1.2". But when I measured this one, the petal free play was only about 3/4"... so less than the minimum spec.
So I loosened the nut, removed the key and pin, and turned the rod coupler out several turns to lengthen it, reinserted pin and remeasured. I had went to far and the free play was around 1.5" now. So long story short, I adjusted it a few more times until a half of turn would get it between just over 1" to 1.25". So I turned it back a half turn and set it at what was just over 1". So its within spec now.

However, when I got everything fully reassembled and done, I restarted the tractor, put down the clutch, shifted it from neutral to forward and.... GRIND.... so immediately put the clutch back down, shifted it into reverse... it engauged no grinding. Shifted it back into forward and it engauged this time drove it around to the front of my barn and parked it, got to move it here shortly though.

So... i don't know. We'll see how it goes. I did double check the transmission fluid level, and its not low.
I sure hope it doesn't need a clutch or worse...

That may be something I have to look into next if it continues. Yeah I don't know why the hi/low range selector is so hard to shift. But from what I've read on some other sites from other LB1914's owners this is apparently a common problem, although from what they describe this one is still harder to move than most.

Did a little work with the tractor today, and unfortunately it is still grinding. I did notice that if I shifted from forward/reverse into neutral and then waited 5 to 10 seconds... then shifted into the direction of travel I wanted to go and slowly let out on the clutch, it usually didn't grind. But if I didn't wait "long enough", then it would grind. Didn't make a difference if it was at idle or 'higher' rpm, nor if I was trying to go forward or reverse.

Owned this tractor for about 5 years, never had to do this before. kind of strange... in any case, it seemed to do better (as in didn't grind as often) than what it was doing before i adjusted the clutch. As before I couldn't hardly backup at all, but it didn't grind very often when I was trying to go forward.
