Description:

Give John Deere fans an unforgettable experience and invite them to recreate every detail of one of the famous manufacturer's biggest machines. Engineering and farming enthusiasts aged 11+ will love learning about the many authentic features of the LEGO® Technic John Deere 948L-II Skidder (42157) including steering, 4WD and a running engine . They will also observe the pneumatic functions which, like on the real skidder, operate the 3 movements of the gripper, the blade and the rotating seat. The LEGO Builder app offers an intuitive building experience: kids can zoom, rotate 3D models, save sets and track their progress. This LEGO® Technic building set measures over 8” (21cm) high, 21” (53cm) long and 7” (19cm) wide.

More info coming soon.

Oooooh, that sounds very much like there's 5 pneumatic functions!

Could also meant in a way, that the gripper has 3 pneumatic functions and the others are just manual. To turn the seat with pneumatic doesn't make any sense to me :D

IF the blade is lifted with pneumatics, I wonder if the little 5L cylinders are sufficient or we get a return of these, maybe in DBG:

Maybe they have now pneumatic rotator? It could be used also for claw operation.

I did think that also (didn't want to mention it incase it lead to disappointment!) like if there's some new rotary pneumatic actuator (not continuous like a motor, but like 180 degrees or 270 degrees of rotation) it would make more sense of the description. It says three movements of the gripper, but on the real one, one of the three movements is the rotation of the claw. So if they have one there I guess why not add one for the seat also? So it would make more sense of the description but I don't want to get anyone's hopes up. I must not be disappointed if there is no new rotary actuator, only very very happy if there is one.

I think that it must be read:

They will also observe

- the pneumatic functions which, like on the real skidder, operate the 3 movements of the gripper

- the blade

- rotating seat

That indicates usage of 107mm tires since real machine is 3.5m wide

But the gripper has four movements, isn´t it?, I do not know if the gripper turns free or not.

Nope, it can move: 1) up/down, 2) forwards/backwards and 3) claw open/closed. These claws usually only have a "return to center" function to some degree or none at all for rotation.

Thanks, I thought it had some rotation to orient the gripper.

Nice to see TLG keeping the tradition of pneumatic forestry equipment alive as well!

Hope it will be in the same league as the Claas Xerion and won't be a LEGO exclusive set again like the smaller JD tractor. I guess we can forget about double wheels...

Actually, the 9R is widely available in the UK as of now, so you might want to sit tight.

Hmm but would be fun to mod it into a 768L-II:

Wow, I like this version, it could be a great candidate for a mix of large and medium tractor tires

I'm affraid medium size (81mm) is to small to maintain correct proportions...

I'm not sure I follow. The description says 3 movements and claw and seat rotation. To me that reads as 1) up/down 2) forwards/backwards 3) rotation and then we have claw open/closed and seat. But descriptions have been inaccurate before. Descriptions from promobricks tend to be more reliable though, so I wonder what they will say of it.

If it was the 6 wheeled bogie skidder version I think ithe proportions would work for the front wheels. The description already confirmed its 4x4 though. May be an interesting mod though.

Well, it is a compromise...on those skidders front tires are 30.5-32 (1877mm diameter) and rear are 780/50-28.5 (1525mm diameter)

the 3 movements of the gripper

The description says 3 movements and claw

It says 3 movements OF (not AND) the gripper.

But I agree, let's wait for pictures or at least a proper description.

Wonder if any of the green parts from Dragon will be reappearing in this set.

7 studs long beam with alternate holes ...

For anyone who isn't familiar with this 🐕, here it is again...

...and I am wondering how this model is gonna use the V2 pneumatic cylinders without being utterly mahoosive.

Maybe it will introduce a new cylinder.

Actually, I would be surprised if it included a new tire, too.

Either or both would make sense.
