Power Reverser quick question. JD 5100e potential purchase

[Dadnatron]

I am looking at a used JD 5100e 2015 with 500hrs.

I've never driven a tractor with a power reverser, and while I like the idea, I don't know about how well the one on the tractor I am thinking about is working.

When I move it from forward to reverse or vice verse, it gives a significant 'jerk' into the new direction. I was watching a video explaination on YouTube, and the guy was on a NH, and changing directions was very smooth.

The more I think about it, the more convinced I am that there might be something 'wrong' with the Power Reverser on the JD. I can't imagine getting whiplash like that when I use the FEL, and while it isn't really whiplash... there is NO SMOOTH change. It is a real time 'jerk/jump' to the other direction. Nothing like this video.

I am going to ask to drive a new tractor and see how it changes, but I'm not liking how that one is moving. If they decided to 'fix it' (since its under warranty for another year) would you have any problems with the purchase? The price is good $47,500 with a 260 FEL.

There should actually be a slight pause before changing direction.

 

[TractorGuy]

Were you reducing the engine speed when changing direction?

 

[brasco426]

Isn't it still under warranty?

Yep..but it's just a fraction of a second.

I have a power reverser in my Deere 4520...still in the habit of using the clutch for direction changes (since my previous tractor with a sync-reverser required use of the clutch.). However, I'll occasionally change direction without using the clutch...it does seem abrupt, but hasn't hurt the tractor.

My Yanmar with Powershift hits RIGHT NOW when I shift. I use the foot throttle and let off it when I shift. When shifting from F to R it helps to be stopped or use the clutch.

Not with the 5065M here, it's a very smooth transition in direction, it takes 3-4 seconds to reach full speed in the opposite direction even throttled up but the 5000M series is definitely not a 5000E series tractor. Most everyone here still clutches, old habits die hard ;-)

Now take the CaseIH 5140 it'll practically snap your neck.

There should be adjustment in how hard in shifts. They actually sell a kit where you can make changes to the shift speed on the fly.

 

[Dadnatron]

No, I wasn't slowing revs. I thought the idea was that you merely switched directions. If it's a slow, clutch etc, then in my opinion, the utility of the reverser is much less useful.

I'm going to drive a few tomorrow and see if there is a difference. I like the smoothness of the NH in the YouTube video, but like I said, other than the couple minutes I drove the 5100e, I have no experience with them. I've always clutched and shifted.

And yes, it's under warranty, but that doesn't help me know if it's working as designed. The folks on this site can help me more than the guy wanting to sell it to me.

I have 2 old Fords, an old case dozer and a 2004 New Holland that have power reversing transmissions. They're all the same, you know when you throw it into reverse. There's no hesitation, in an instant your going in reverse. I drive in to a pile at high rpm's with the differential lock down (sometimes), throw it in netural and raise the bucket, let the rpm's go down to 1100 or so and reverse out. If clutch tractors are all you've ever owned, it will take some time getting use to. If your rpm's are to low when you drive into a pile while raising the bucket you'll stall the tractor. Once you get the hang of it, you'll never want a clutch again.

I drove a 5100M and the 5100e that I'm looking at this morning.

The abrupt shift in direction was noticed more in the very low gears compared to more normal 'working' gears. Both were similar, so I believe that the quick action is just how things work. I spoke with the Technician who works on them as well, and he said unless you have the option which allows you to adjust the speed of reversal, this is pretty standard and won't cause damage to the tractor or transmission.

Thanks for your input. I feel much better about it after hearing your experiences and checking it all out again.

I agree with the technian as long as it doesn't shift really hard its better on the clutch to execute a crisp shift as opposed to slipping particularly if the revs are high

Correct, there is a kit that you then can change fill pressure settings for forward and reverse. lvb25727 (verify this # based on unit s/n though) and is not terribly expensive. M series units would already have this feature std.

I'm buying an m series but don't recall it as standard feature but an option.

 

[bigdeano]

It's probably easier on the parts to throttle down before reversing direction. I always did that on the Cat D3 I had.

It was not std. on the 5065M but my wife and son them put it on there and no matter where you set it, you can't tell a spits worth of difference, I don't think the dealer programmed it properly. The direction change is very smooth in every gear I've tried but I rarely drive it so can't say about every speed or RPM setting. One strange thing I find is that the reverse speed is a tad faster in each gear than forward according to the manual.

Sorry, what I should have said is that it is standard for current production machines with the 32/16 tranny. Did not mean to mislead, it is not std for all transmissions.

On the 6430 it seems a bit jumpy but I'm still used to the clutch.
I once ran down the road at 25 mph and wanted to turn the signal on and put it in reverse instead. No difference in direction in that case. It killed the engine.

Well I didn't know that either. Thanks for the info.
