is 4x4 workig right? B21

They really do have 4-wheel drive. If you lifted a tractor so all 4 wheels were off the ground, engaged 4x4, and put the tractor into gear (or pressed the forward HST pedal)...all four wheels would be spinning. The action of the differential is what causes loss of traction when on surfaces of unequal grip.

PLACE two and only two of those tires on the ground....then you will understand....

yes ALL 4 WHEELS are driven.......but not ALL FOUR wheels can and will do work! Depending on the friction, one will always move faster/slower than the other side!

4 wheel drive and ALL wheels working no matter what are two entirely different situations!

any tires can be spun by the system - but once ONE tire is free, it will spin until friction is applied to it externally.

I***8217;m glad we aren***8217;t all at the same bar together having this conversation lol, from what I see y***8217;all are arguing the same point! The only thing I see is going after troverman for saying the open differential can essentially spin all 4 wheels at the same time. In the most perfect situation it could essentially spin all 4 wheels,but it would be very very rare to have the most ideal situation to have all spin together.

And trover has also brought it up that the path of least resistance is the way it will go which is correct and it***8217;s what everyone else is saying.

This thread is giving me a headache.

So to clarify:

if you have a fifth wheel hitch setup it only turns when you engage 5 wheel drive

I feel ya lol, glad these kubotas don’t have computer controlled 4wd systems!

How about a tri-axle dump truck? 6WD? What about a dooley is that 6WD or 4WD?

This is fun!

You guys are looking at this all wrong.

In 2wd, one wheel digs down into the muck. You'll need to use the FEL or backhoe to pull yourself out.

In 4wd with open diffs, 2 wheels dig down, getting really stuck. Better have a winch and a tree handy.

4wd with a locking diff means 3 wheels dig down so far the tractor is high-centered. Time to go get another tractor and some chains.

But with front and rear locking diffs, you can dig yourself in so far you'll need a crane to lift you out of the hole!
