It's a similar issue.Until you get to the full sized tractors, the front axle is usually a locked differential when engaged.
If the front axle is a locked differential when engaged, you still get driveline tension and wheel hop; in this case, the tension will be between the front and rear diffs (because the front axle will still be turning at a different speed than the rear) as well as to the right and left of the front diff (between the front diff and each of the wheels) because once again the left and right front wheels will be turning at different rates.
The same thing happens in the rear when you lock the rear differential and try to turn.
I stated "4wd truck" in particular because 4wd systems are generally considered to have a solid connection between front and back (ie, transfer case) as opposed to a center differential, which may or may not be lockable (generally considered to be "AWD" and specifically called out in my posting).Not sure about trying to compare it to a 4wd truck which would have an open, remote, or automatic differential locking system.
