You need balast or you will trash your front axle!!!! really?

...And here's an example of a broken front end: http://www.tractorbynet.com/forums/parts-repairs/353044-broke-front-hub.html
Playing armchair warrior and with all due respect to the poster with the broken front hub my personal feeling why he experienced a failure is due to not enough counter weight. If 4wd was required to move around the gravel to maintain traction (ie stop rear wheel spin) then there wasn't enough counterweight being used. I know from my personal experience a rear blade while not a bad counterweight is not enough for heavy loader work. (I'd have to use 4wd) But the same work with a real counterweight (in my case a concrete barrel) is plenty that I find I basically never need to use 4wd except in extreme circumstances (mud) where I need a little more traction. And in those instances I only use 4wd momentarily and then go back to 2wd.
Again - I'm using the above as an example of what could be the reason for a failure to happen. Might not have been root cause, just my 2 cents. Something to consider when you're using your tractor.

I saw my first yellow jacket of the season. That's one nice thing to not worry about during winter.

I was walking the shoreline of one of my ponds a couple days ago and a frog jumped in!!!!! I was very surprised. Personally had never saw one this early.

I'd rather have frogs than your yellow jackets......

Plesse support this with some logic in reference to the pics of the failure point.

Not to stir up a bees nest but- Sure seems that (style) of end Knuckle seems to be in more threads when there is a leak or problem, than some other styles, but I could be wrong??
This thread the question was asked
http://www.tractorbynet.com/forums/kubota-owning-operating/183502-4x4-kubota-front-axle-hub.html


and that thread referred to these statements in another thread:

What do you consider the fault to be in this design? For some reason kubota seems quite attached to it and I personally like the obvious benefits of this design. Of course I haven't had a leak yet.

The grand L front axle was a departure from previous designs - which were inherently stronger because the king pin housing was in double shear, with bearings above and below the axle joint. The grand L kingpin joint is cantilevered. I wouldn't go so far as to say it is a faulty design, it just doesn't have as big a strength margin, and with vigorous use it seems to have had a higher incidence of seal and bearing failures.

I think there is merit to this exchange, and this thread showed a comparison of 2 designs, http://www.tractorbynet.com/forums/kubota-owning-operating/123302-need-help-w-kubota-l3710.html



Agree also that more ballast on the 3 point would probably have been beneficial.

I have an idea as well....
