Power Reverser Opereation

[MMH]

I just bought a 2000 4500 w/ a Power Reverser. What is the proper way to run a Power Reverser? I assume that I should be at a full stop when going from forward to reverse. Is this correct or can I be at a slow roll? If I shift at a slow roll will the wet clutch be abused & wear prematurely? Also, I assume that I can shift gears 1 thru 4 when on the move but must use the clutch. Finally, when shifting ranges, I assume that I must be at a full stop & use clutch.

Can someone please verify?

You can be moving even at a decent speed and switch direction without clutching. The faster you are going the more abrupt the direction change will be and of course it will be a little harder on the tractor.

The best way I have found to use a tractor with power reverse is to set the hand throttle at a certain level that provides good steering and loader response (maybe 1400-1600rpm or so.) Then apply throttle with the foot throttle when moving, let off the foot throttle when changing direction. This allows you to change direction more gently, but still move more quickly between whatever you are working on.

Unless you are really abusing it with lots and lots of fast, high RPM direction changes the wet clutch will give you no trouble at all.

The rest of your transmission operation sounds right. Shift on the move with the gears, stop for the ranges.

I wouldn't use it to change directions except when using the FEL in a lower gear. Avoid using it in high gear. It has 2 clutches internally, 1 for forward, 1 for reverse. Just like not taking off in a standard car in a high gear.

Keep the mechanism in the dash lubricated and don't slam it into park while still moving or you can break off an internal pawl that is $$$ to replace. These things last a long time with a bit of forewarned knowledge.

If you did not get an operators manaul with the tractor. Here is an online copy.

If you are going forward, you shift it to reverse. It will deal with directions changes up to speeds much higher than your body will like! The general steps I use are let off foot throttle until the rev's drop to idle then pull the reverser and get on the throttle again. Its ok in high range on my MF but it jerks you so bad I usually use the clutch to gently reverse.

Kyle and slowzuki are correct in regard to using the reverser in the higher ranges! You won't like the high G's and while the tractor will do it - probably for many years - commonsense tells you it's probably not a smart thing to do to your tractor...

I am surprised reverse is not locked out in the higher ranges. Who needs to go from 18mph forward to 18mph backwards almost instantly? :confused2:

On my JD 2030 Reverse is on the range stick, so no way you can be in both High and Reverse. The other stick is 1, 2, 3 & 4. When in High range they are 5,6,7 & 8.

On the 6415, It has 4 ranges, 4 speeds and a PowrReverser. I have not even considered shifting into reverse at speed!

I've got the sync-reverser which does require the operator to stop before shifting forward to reverse (and vice-versa).
Although the power-reverser does allow you to shift while moving, stopping momentarily will probably extend the life of the mechanism.

Yeah.... that'd be something for YouTube! Or Jackass III! Have to have a tape measure to see how far it would launch your body out of the front seat!

I couldn't agree more. My wife's operation has a CaseIH 5140 with power reverse and they darn near comes to complete stop before changing direction. I know it's meant to handle it without stopping but the tractor weighs about 12,000lbs by itself with weighs and fluids and that's lot weight just to be going along at 5 or 6 mph and jam it into the opposite direction.

Thanks for the link - it was very helpful. I also have the 48 backhoe for the 4500. Can you get me a link for the operators manual for the backhoe? I tried to navigate thru the JD site but could not get there.

Thanks.

Here is 4 links: 1) The link to online JD manuals, goes back to about 1999. 2) Link to 48 backhoe. 3) JDparts. 4) Sign-up for free and get parts availability and cost.

If you got a loader with your tractor link 1 you maybe able to find the manual

I think as long as you're reasonable it will last, I've never heard of a wet clutch on an ag tractor wearing out.

BTW On my 5455, it won't reverse over a certain speed, it will just put the shuttle in neutral and flash the reverser lights. I've never tried to go that fast, it already just spins the tires if you all going at a good clip.

Thanks again for the links. I do have the 460 loader. I could get to some of the pages for this loader, but not the entire 460 'file' as I did for the 48 backhoe & 4500 tractor. Is there anyway to do this? Also, is there anyway to get this as a pdf file?

 

[JD5210]

I only looked at a dozen pages, but had no problems with the 460 loader. I have included the URL.

On the pdf, you can order them from JD. I would go through a dealer, JD shipping is high. The operator manuals on cd are about $30. You can also check e-bay.

Just traded a 4600 for a 4520. 4600 was 12 years old with power reverser. Worked it bunches and bunches of times without clutching and in motion with never any issues. Learned quickly not to work it if tractor is moving too fast as some of the other comments indicated it jars you pretty hard when switching. The 4520 comes standard with the PW, wouldn't do without it. My 6100D also equiped with same.
