42157 - Skidder John Deere 948L-II

[AVCampos]

I think it's better to baby-step builders than to handle complaints that "these legos [sic] don't work" from builders who didn't pay close attention to the instructions.

From the video ,  it is a good looking working machine , very big scale, and with some improvement it will be a fantastic  backhoe loader , which I have been waiting for long。

I always wonder how some people manage to get their hands on sets almost 3 months before release? Judging from review, Lego has to again baby-step the differential assembly and orientation and put additional bricks to prevent incorrect placement.

It's available in 2 weeks?

This is the channel of JB Spielwaren, which is LEGO shop. They get stock from TLG well before the release (even the reveal) date, all shops do. But this shop (and another one in Romania) decided to exploit the system and they use their own stock to create unboxing / speed build / review videos after the sets are revealed, but way before the review embargo of RLFMs. Technically they don't brake any rules with TLG, and apparently no one cares enough about it to change rules affecting all of their business partners. So the recipe is fairly simple, if you want to be first with LEGO reviews, you need to open a shop.

I'm still waiting for Sariel's review myself.

[AVCampos]

Me too. Sariel's and RacingBrick's.

The tires are mounted wrongly in the video

I noticed that as well. Read the instructions, people!

I don't understand his language but I think he put the diffs in wrong also.

If and when more progress is made I will make a dedicated thread unless someone creates a mod thread already for the original set, in which case I will post on there.

Here is my 42157 John Deere tractor WIP mod.

Pneumatics replaced with linear actuators.

As many motors as possible, connected to BUWIZZ 3.0.

@SNIPE I'm surprised no-one has made a 42157 mod thread so feel free to start one.

Only concern I have right now is the placement of the pneumatic switches. Seems like hard to reach when the boom is retracted all the way.

Indeed! and these new switches would be perfect to mount in the roof since the 5 hole wide base wont cause it to bend and flex like the old ones did

[Jockos]

Surely it was placed there due to aesthetics. Additionally, I would put some axle connectors on them

[Maaboo the Witch]

While we're hovering around the subject of aesthetics, I've just noticed that, in the set images, the axle on the roof steering gear isn't pushed all the way in.

I'm working on an alternate model, and this set is a pain to work with.

It has:

- 7 15L beams
- 3 flipflop 15L beams
- 5 13L beams
- 3 11L beams

The wheels are too big while the structural elements that match the scale of the wheels are too few.

There's also the problem of gears. This set has:

- 1 bevel 12z gear
- 1 bevel 20z gear
- 2 bevel thin 20z gear
- 12 bevel thin 12z gear
- 1 spur 20z gear

The lack of bevel gears make it hard to route drivetrains around so that the manual input is at the desired place and hard to gear down drivetrains.

Probably you can make something like this (it has articulated steering, rear 3 point hutch, rear drawbar and rear pto)... O suppose you don't plan to make helicopter of it ...

That's because sets these days aren't designed to have B-models.

[Ngoc Nguyen]

Oh and it has no gear rack either. Very barren set for alternate models.

You could only put 3 bevel gears in the differentials, that should save 2 gears per differential (4 total)

Also, even half bevel gears can be used as spur gears as long as it is not with a double bevel gear. E.g. a 16 tooth and a 20 tooth single bevel gear meshes just fine as a spur gear pair.

I think 2016 was such a good year for technic that that the only way up from there,  was down. Compare this set to the 42054 claas xerion (which came out along side 42055 and 42056) all 3 of which were flagship level in their own right. Also for 1h, we got the heavy lift helicopter.

Now we have 42157 and well... it has less parts, no "B model", no electronics, less functions and mechanisms, just as many new parts or recolours and about just as many pneumatics.

edit: oh, and someone made a 42154 MOD with 8 motors (drive, steering front, steering rear, front attachment, rear attachment, PTO, cabin rotation, pump), LED's with a PF switch, pendular front axle, two buwizz 2.0, 4 wheel drive with the newer CV joints , planetary hubs. etc. So, yeah while 42157 is "good" it's not "2016 technic good".

You're forgetting 42053!

Anyway, 2016 was indeed excellent but, for me, 2018 was the last truly great year for Technic. 2019 strayed close to the edge of the cliff, and 2020 is when the theme went over it.

[GoldVillage]

Come on guys we all know the 80's was the best ;) 

[AVCampos]

Technic was great until they ruined it in 1977.

;D

We had better and worse years. The lineup so far for 2023 is pretty solid, also considering the upcoming models. And I'm happy we are getting good pieces for MOCing of Deere machinery.

You cannot push that axle more in, it's a 4L axle with stop but there are only 3.5 modules of "layers" used below it with the connector, the panel, the gear and the half bush.
