I recently pruchased a B6100D and I'm having problems turning it off. The Operators Manual states that the lever should be slow when pulled back and fast when pushed forward. On my tractor, it is just the opposite. Any suggestions on how this can be corrected? I believe that this will help solve my shut off problem as well. Thanks!
Accelerator Lever
- Thread starter Tr4RIguy
- Start date
I can't speak for other models, but on the B7001 it is back (towards the operator) for higher rpm's. I can't imagine Kubota making one model of the B series different, but ????
I have had a shut off problem with mine since I bought it.
There are two springs inside the governor case. The longer one is the governor spring, which controls operating rpm. The shorter one is the start spring, which is supposed to put the rotating arms at the correct idle position, then when you push on the linkage it will shut off the fuel, then return to the idle position when you release the linkage.
On mine, the shaft appears to be a bit out of alignment. When a start spring is in place, I can not shut off the fuel and have to use the decompression lever to stop the engine. When I remove the spring, the shut off works fine, but the engine will not find its own idle speed - I have to work the throttle so I don't slow it down too far and stall it.

Thanks Stuart for the reply. According to the Operator's Manual, the engine shoulld accelerate when the lever is pushed forward and decrease when pulled back (towards the driver). I'm hoping that Service Dept. Vic has some input as to why it is this way. Also, once the engine has slowed down with the switch "off", the engine doesn't shut off. Everything around the rod, including springs, looks normal. It doesn't look to be missing any spring or anything like that.
Most all small tractors/lawn mowers push fwd to acc. and pull aft to de-acc. and Foot feed do the same. Most/all larger tractors pull back/down to acc. and push fwd/up to de-acc. Sounds like yours is wrong (by the book), maybe previous owner reversed a bellcrank or lever to get it to work in reverse of the book and more like a large tractor??? Follow the linkage and see if you see a place where linkage can be reversed up/down, left/right to make it work backwards. The throttle will get engine to idle, do you shut it off with the throttle, pull another button or turn the key off???
On my B 7100 that I had the throttle worked like this. It raised the RPM's when the lever was pulled back and lowered when it was pushed toward the front. The ignition switch is not supposed to kill the engine on these models. Mine had a small yellow lever kind of under the right side of the dash that had to be pulled to the rear to kill the engine. Hope this helps.

I realize I was not clear about this. the two springs are inside the housing, it takes a few minutes to open that up. When I put the new spring in, we tried to shut down using the throttle lever only - push forward to stop engine. I had forgotten about the little lever mentioned below - never used it ('cause it never worked before). So, I have to open up the housing again, replace the start spring and test the lever. I don't think that will help because of the alignment problem, but in a few weeks I'll have some spare time.
If you search back to September or so in here or the grey market section, you will find the set of posts about the problem.

Thanks for the information. I did notice a lever under the dash that when operated, it moves the accelerator rod further forward which i assume shuts down the engine. I will give this a try in the next day or so. Thank you for relying to the posts!!! Chris
