42157 - Skidder John Deere 948L-II

[mpj]

A bit overpriced... 190 Euro for 1500 parts. 

Compared to other pneumatic sets:

42128 is 10 Euro less for 500 more parts.

Still better than 42144 which is 120 Euro for the half of the parts!

and maybe kept in place by half-pins.

But it's still weird to find a Technic piece with holes at slight-more-than-integer distance between holes.

That said, if the expectation that it's 16 long is correct, then the triangular parts have a 1:5 ratio, which would be half the angle of a 5:12:13 triangle which is known to have almost exactly the same angle as the #3 and #5 angle connectors.

It's not that weird if the part in question is at an angle, like this piece:

We don't have a beam that can span the holes of the middle section.

Pretty much what I wrote on page 1 of this thread but I did not want to type it out again...

Oil and energy prices are still driving up inflation, not sure how things are now compared to last 2 years but it's still not what it should be. But there's also 4 huge wheels and tyres, more pneumatics, the large grab pieces and some large frames. It would be interesting to compare the weight of the skidder with 42128 as that would be a better indication of their relative value.

Price per part is not always a good measure. This set has more pneumatics and a massive tyres that cost more to produce. It also has a license.
The same way that it really shouldn’t be argued the Eiffel Tower is a very good value (€630 for 10001 pieces), when thousands of the parts are just 1x1 plates or variants of it.

But this part has an angle of 90 degrees, and both ends are in a flat grid, that is, they can be connected, and in this new frame, the two ends cannot be connected by a straight beam.

That's right, this set also has new "A" shape frames whose price should be important (new molds, etc)

[SNIPE]

Soo

1 smol turntable for the claw

2 smol turntables for the pendular rear axle

2 large turntables for the steering/boom pivot

3 pneumatic switches

5 XL pneumatic cylinders, (one in yellow , four in dark bluish gray)

2 smol linear actuators

2 daytona large bevel gears

2 heavy duty diff cases

2 daytona small bevel gears

4 hubs (probably just hubs from 42125 and not planetary hubs, I dont see any portal hubs)

2 green 3x19x1 girder frames

2 new claw pieces

2 new A frame girders

engine, plenty of gears, plenty recolors, big tyres

I will for sure replace the pnumatics with XL linear actuators and add control plus and buwizz 3.0!

Removing pneumatic elements and replacing them with CON+TROLL? That's a paddlin'.

Anywhen, to keep things on topic, here are some Deere facts!

948L-II Skidder

• Gross Power: 224 kW
• Gross Torque: 1,369 Nm 
• Max Grapple Capacity: 2.07 m² 
• Operating Weight: 22,484 kg

Is that a biscuit frame in yellowish orange next to the diff?

I was considering the same. Looking forward to how you will tackle providing the claw's LA with power but having the claw still swing freely (motor inside the claw will be too bulky I reckon)

[AVCampos]

Keeping the claw pneumatic would solve that problem: it only needs to be fully open or closed anyways, and pneumatic has the advantage of applying constant force, which is good for grabbing claws.

Could also be a normal axle connector.

I see normal wheel hubs. But for the front axle, they are only secured by axles and not pins? Would be kind of wobbly imho...

Not sure but at first glance I don't think so, I think it's just the straight connector. To me it doesn't look like there's enough space for a biscuit frame and pinion gear in that 4L high assembly of green frames, based on this photo:

Am I the only one who thinks that the new claw piece looks really like a banana?

Well, the banana gear might have a say...

[AVCampos]

They are two bananas. One of them is a gear, the other is a claw. Together, they fight crime!

Can we assume the steering mechanics will be similar to the 42136 set, just larger? It's a very simple and effective means. 

 

I definitely see this as a good base to install some PU capabilities. 

The functions can be seen in the official video:

for noobs like me this distinction was not immediately apparent.  Thanks for pointing that out...

Okay, so this model definitely has a swiveling seat in it, which allows the vehicle to travel in both directions, and definitely has a suspension system of some type as we see towards the end of the hyperlinked video. This video does not show the model's piston engine in action, however.

Now I'm wondering how difficult it's going to be to control that steering mechanism with a PU L-motor. I guess I'll have to find out later this year!

It actually looks like  banana. Maybe this part will come in another mario donky kong set?

[R0Sch]

If you want to know exactly how the claw operates and how the cylinders are connected to the frame, here's my WIP: 42157.io

[Zerobricks]

I see the reason, they used the yellow, stronger diff. The front axle does not use the usual 5x7 frame to hold the diff and gear in place and without it a normal diff would probably skip if overloaded. Also the A frames are exactly 16 modules long, I think the flip flop beam is just attached in the bottom and uses a half pin somewhere to keep it centered on the A frame's... frame.
