For almost 2 years now after trading off the Z9 for the X758, which I made the trade because the Z9 was very prone to getting stuck, a lot.

In fairness to the X758, it’s rained here every day for 2 weeks straight, been having to use the X758 to mow the entire yard over the past 3 days, just too wet to get a tractor with the batwing out on the lawn without rutting things up.

This was the First time I ever needed to mow everything with the X758.
It’s taken me 13 hours over 3 afternoons and evenings. At the very end tonight I was pushing it closer and closer to edge of the pond, finally got a little too close and sank the right front all the way to the frame in a split second I was totally stuck. Lol😁

No big deal really, took longer to wash the mud off then it did to pull it out. . Lol
I guess you can get one of these Awd X758‘s stuck after all. 😝

Did the 4720 even know it was pulling something? 😁

Well the 4720 got upgraded to a 5115M last month, and no it really didn’t notice it was pulling anything at all.😁 lol

Also Thanks for the reminder, I have now updated my signature with currently owned green machines .

I like seeing photos of other people's stuck equipment.

I also noticed that with my 1026, 4 weights up front works better then 5 for mowing.

Looks like the deck got you hung up. If it wasn’t for it, probably you could have backed out? How well does the 4wd work on the X758? Does it spin the front wheels like the larger tractors? I’m just thinking about getting a 758 and don’t know if it’s worth the extra $.

No big deal. I’ll just pull it out with one of my other 12 tractors.
What we’re you trying to mow? Dirt with one weed that just had to go?
Looks like something I’d do so I didn’t have to use the weed wacker lol

The AWD on the x7 is not a standard 4wd axle like most tractors.

The front axle has an independent hydraulic motor for each front wheel. The is a hydraulic valve linked to the steering that acts as a "differential" and changes the power to each front wheel when making turns. Turning the wheel to make the stuck wheel the "inside wheel" in a turn will send more power the wheel wheel that still has some grip.

The rear axle is independent of the front axle with no mechanical linkage. The rear axle works exactly like you would expect a hydro axle with a differential lock to work.

When stuck or close to being stuck you will generally spin 1 front and 1 rear wheel.

More often than not the diff lock on the rear axle will give you enough traction to back a front tire out of a hole. The one time I got my x738 stuck was when I high centered the tractor on the mower deck trying to get over a much higher than expected lawn edging.

I've been thru mud mostly covering the front wheels without the deck on and not gotten stuck.

The AWD on the x7 is worth every bit of the cost.

Thanks CJ! Never knew it was hyd motors for the front wheels. I just assumed it was mechanically driven. I’d love to see one in person, but none close to me. Thanks for your explanation.

Myself being the owner of an x758 for several months now still am not sure as to fully understand the front wheel drive traction.
I know the two hydraulic motors turn the front wheels.
And as mentioned wheel speed on turns is controlled by the right linked control rod.
There is no differential just two hydraulic motors always fed fluid from the rear axle.
Always supplying each front wheel motor hydraulic power.
Aren't both front wheels always pulling just at different speeds on turns?
I have never gotten close to losing traction
even last winter in the snow.
So I have never seen wheel spin front or rear. .
Like a typical differential front axle on
Only one front wheel spins during loss of traction say like on a 1 series...
I think both should spin/ pull on the HFWD front axles...??

Exactly. LOL 😁
I think I had it pulled out of there in under 10min.

I had been back filling this area in last fall, and it was starting to get weedy so I was gradually working my way out further and further seeing what all I could get mowed down.
I was headed for this one last pass and sank it.
The area right in front of where I sank it is what I was after.
I got it or most of it once I pulled it out.
I went around and pulled straight in and back out till I got most of it.
I can be stubborn that way.

Exactly, even with the diff lock I could not back it out since the bank was still pretty wet and slick, and I was partailly hung up on the deck on that right side where the right front sank into the pond bank.

I never had any issues with getting stuck at all with the X758 not till till last night. Totally my fault.
I was just pressing my luck working my way further and further out toward the bank on ground I knew was wet and I could easily get it stuck. I just thought I could watch it close enough and catch it before I would get hung up. That bank is really rough and steep in spots. I was watching my left side mowing track and should have been watching my right side when I was that close to the waters edge.

I finally got around to doing the RIO and seat overrides last weekend and now that I can get positioned on the side of the seat I can mow some crazy steep ditch banks with it now. I could mow them before, but the seat switch would shut off the tractor whenever I would lift up to change balance positions. The X758 is easily the most capable machine I have ever owned when it comes to adverse terrain.

Nothing wrong in getting stuck. It’s how you can test your machine and know how far you can push it.

If a front wheel loose traction or say is dropped into hole totally suspended in the air or say a pond in my case yesterday. The front wheel with no traction will just spin, the other front wheel will provide no assistance in that sort of scenario where one front wheel looses all traction. The diff lock will lock the rear wheels and most of the time, that can get you out of being stuck.

The valve linked to the control rod is a proportioning valve. It changes the fluid flow to each wheel which in effect drives one wheel faster and one slower when turning.

In the case where one wheel has lost all traction on the front axle that one wheel will spin and steady most of the power from the other wheel. You can cheat the system a bit by cutting the wheel hard to one side to close the proportioning valve and try to force traction to the other wheel. That only works to a point though and sometimes stuck is just stuck.

If you are going to use it for mud bogging you need a winch on that thing

Once the wheels load up with mud (or packed with snow) it's a done deal - might as well be running slicks.

Kinda sad to hear the hydrostatic FWD is not much better than the old differential side/spider gear differential axles when stuck going straight ahead only one wheel drive....
