L3400DT shifting

ArkCivEngr · Apr 19, 2005

After 9 hours on my new L3400 (LA463, BH75), I'm discovering just how much work I could have been doing the past 5 years had I taken the plunge sooner. This thing is built like a tank and has proportional power, and still is small enough to be very maneuverable.

However, I'm grinding gears whenever I shift out of neutral. /forums/images/graemlins/blush.gif And it doesn't matter which way I do it: either shifting from neutral to low range and then selecting a gear, or vice versa.

If I'm already in low range and shuttle into reverse, there is no grinding. Same for if I'm in reverse and shuttle into low range. Just a nice, smooth little click. /forums/images/graemlins/grin.gif

I have been doing as the sticker on the dash says and pushing the clutch all the way down (not just halfway) before shifting.

I must be doing something wrong. Any clues? And no "engineer-on-backhoe" jokes! I hear enough of those at work! /forums/images/graemlins/smile.gif

Interesting!! I have a brand new B7510DT (12 hrs) and I too have a bit of a "notchy" time shifting, especially into 2nd and 3rd gear. I have tried double clutching, slight rolling, 1st and reverse then attempt 2nd or 3rd, but nothing seems to help. I think I may have to go back to the dealer and see if the clutch needs adjusting. Any suggestions would be welcome!

Sure love to hear others enjoying their L3400DT as much as I do! Why did I wait so long???

If I am in a rush, I tend to push the shifter a little too quickly which howls back with a grind....makes me feel rather amateurish. If I pause long enough to inspire, and be certain I have stopped moving before changing directions, I find it to be smooth and silent.

At only 10 hrs on this machine, I have in NO sense mastered smooth operation.

I love this tractor!!

love my 3400dt. I scrape gears at times dont seem to do it iF I come to a complete stop. I was woundering if any one had same problem. I do love my 3400 great tractor for money for sure.

I found that I have to come to a complete STOP before shifting gears unless I want to hear the sound of grinding metal. Stopping takes maybe a second or two longer, but the $$ I will save on a repair bill is worth it.......

I'm aware that the transmission isn't synchronized; as I stated earlier, the grinding is when coming out of neutral, which is from a complete stop. And the grinding is from either stick: the R-L-H, or 1-2-3-4.

It seems to be getting less frequent over the past day or two.

The only time i haver ever noticed any grinding with my L3400 is when I shift from neutral to high or low range. To remedy this, I wait about 5 seconds after pressing in on the clutch to let the gears stop turning. No problems. When first starting out, this does not happen. When I notice it is if I set the brake, put it in neutral and dismount the tractor with it running.... Get back on, press in clutch, go for hi or low range and grrrrr goes the gears.
After pressing in on the clutch, wait about 5 seconds before shifting into gear.. Works for me, and hope it works for you as well.

I have the same problem shifting my l3400. I think we need to slow down and be patient. Let the gears stop before trying to shift, especially from neutral to a another position. Slowing your engine speed also helps since the gears are not spinning as fast. Newer tractors seem have this problem more than the old ones because they have 10w30 weight fluid instead of 90w like the old ones had. I keep telling myself to slow down but I will occasionally make them grind regardless.
