Front end goes out again!!!

[bfloyd4445]

Let's stop and think about this a second.

A. Pretty heavy load of rock in the bucket

B. In 2wd it starts spinning. Well what does that tell you? Does it say the rear wheels are off the ground or extremely limited in their weight carrying ?

C. Engages 4wd . . So now all the weight and all the drive requirements are on the 2 front wheels.

D. Now this has happened multiple times where the front end transmission goes out?

E. If this were a hydraulic problem the pressure relief would have kicked off. And that didn't appear to happen that it was the hydraulics. So if the front wheels were sliding or moving and you shift it into 4wd, it would set gear teeth against gear teeth. Was the rear differential lock also depressed at the same time?

Normally I'm always in 4wd before I start lifting a heavy load.

You made a very good point. With the rear w spinning its an open and shut case. I have trashed jeep front axles and diffs by loading up the front axle then dropping into low range like a dummy shifting the entire weight I'm winching onto the front axle wheels cannot turn but engine can something has got to give. AxleHub you hit the nail on this one i believe these incidents were caused by operator error

If I can't toss a hand full of rocks in a loader and use 4 wheel drive, what h___ good is four wheel drive??? If the loader will list it, with today's relief valves, you can not be overloading things. If dealers , salvage yards are telling you there is a problem with this model, that's all there is to say. Open and shut case. What about the 3 times the front axle failed and no rocks were involved. What about the steering cylinder??? This particular has from end issues.that is open and shut case, admitted to by an agco dealer and 2 different ag salvage yards.

You can but you have to have the weights balanced from front to back so the load is evenly distributed between both axles when you fill your loader. Its really very simple, as simple as a balance scale or beam. I searched the net and i found no documentation of this being a major issue. All brands and all system have failures but when one person has multiple failures when no one else has it indicates his methodology must be causing the issue. Its time you listened to the constructive help from multiple posters and analyzed the way you are using your tractor in order to ascertain your error then correct it. Add rear wheel weights and more weight in your ballast box and I'll bet the problem goes away. My wife is mean vicious and her new car has had the turn signal arm broken off twice and she has dented the steering wheel face which she blames on the dealer. She is like that with everything when she gets worked up she destroys and doesn't even realize she is doing it. I sincerely hope you are not like her.

Best wishes

I doubt there’s a single compact tractor on earth with over 100 hours and a loader that hasn’t sea sawed over the front end a few times. That shouldn’t bust the front end.

But if you are in 2wd and your wheels are spinning and you pull the lever to engage 4wd while the rear wheels are till spinning. . . It will then.

Yeah, given that the maximum load is governed by the relief valves it's poor engineering to not build a tractor to withstand that standard case.

I've also never seen mention of it in any user manual aside from stability, unlike how you see for backdragging with a loader.

:thumbsup:why is that so hard for people to understand<smile>.....the wheels are spinning cause all the weight is on the front axle then you slap it into gear with the engine reved somethings gonna give.

I'm not trying to be disrespectful or sarcastic, but I also never seen listed in any of my new car owners manuals that driving into a brick wall may damage your new car. They cannot list everything. Most manuals have several pages of common sense stuff in the front put there for people without any.

Yep, I agree. Everyone that uses a loader has felt the bounciness of the rear a time or two but i think most take that as a warning and adjust the load or proceed with extreme caution.
Don't you think so? Most learn from the experience

I'd agree if I hadn't seen every manual talk about backdragging the loader in an extended position(even in our '81 Ford manual!). Both the Ford and Kubota manual talk about ballast but neither mention anything about blowing out a front end and honestly I think we'd see a few more threads on it if that were the case.

Built plenty of consumer stuff over the years and you *always* design for worst case because if you sell ~100k units even that 1/1000 means you've got 100 pissed off people kicking up threads like these which can have a huge impact on how people perceive what you're building.
