HST popping out of mid-range into neutral on downhill

[beowulf]

So when it has happened to me I'd put the blame on the driver, who is otherwise blameless

Cougsfan - I am not glad to hear it happened to you but am glad you told me it happened to you as well. And, well. . . yeah, I have to blame the driver as well. Lesson learned.

And on a downhill run it is scary as it really takes off on you. And I would rather blame the driver for this one than have something major wrong with the tractor. It is cheaper to 'fix' the driver than the tractor.

I stick my water bottle down by the gear select on the MX because it doesn't fit in the cup holder and it has knocked the selector to neutral a time or two. It is scary. And yes it's my fault.

Few or any tractors especially CUTs have front brakes.
With any FEL loads going downhill U should always be in 4WD (AWD) as you then have engine compression working for you.
Loaded FEL removes most weight from the rear wheels.
That or be real fast at dropping your load in order to skid to a controlled stop.

LOL, been there done that! (changed my shorts)

I too have had that happen on my LS. I am pretty sure I did not fully engage gears and knocked the shift lever out with my knee while traveling over rough ground.

If this was a problem with an automobile there would be mass recalls, headlines, and Congressional hearings.

I'm not sure if running in 4WD will help your braking if the transmission is in neutral. Your tractor is 20+- years old, but how many hours are on it?

Why not? With 4WD engaged, the front axles is tied directly to the rear axle. Doesn't matter if the tractors is in gear or not.

Brain cramp, that's why.

I could see a transmission coming out of gear in those situations;
heavy load in the bucket the front tires are compressed shortening the loaded radius considerably,
that in turn calculates into a much decreased loaded circumference, this will take the front axle from a small lead,
to a lag compared to the rear axle.
The rear axle is almost unloaded but is giving a pulsing traction slippage this is the same as backing slightly of the throttle and unloading the gears to shift a manual transmission without using the clutch the down grade is likely giving just a bit of weight to the shifter, the traction pulsing is loading and unloading the transmission the little bit of weight is enough to be like a two fingered clutchless shift.
