I guess you're right since I haven't tested that option. Lower RPM certainly make this case even stranger. Maybe space constraints in the back part do not allow for the gearing mechanism to be placed or stronger motor is required for the 3rd power function which I can't figure out. I think the real question is which of the following options has the best cost/benefit: 1) 1 pump + 1 M motor = cheapest / lowest speed / smallest space consuption in the back cabin b) 1 pump + 1 M motor + gearing up mechanism = cheap / sufficient speed / modest space consumption c) 2 pumps + M motor = expensive / sufficient speed / significant space consumption d) 1 pump + L motor = maybe cheaper than option "c" / performance unknown / small space consumption e) L motor is needed for B model or 3rd power function

I'm arriving late to the discussion but I guess they've opted for the L motor because of the double (large) cilinder configuration that lifts the log. Those cylinders have large volume that needs to be filled quickly in order to have decent lifting speed, at least judgeing by this video https://tinyurl.com/ybwk5ntb where small pump and M motor supply one cylinder at the time. Or maybe it has something to do with the B model where they need additional power.

Is this that mysterious 40th anniversary commemorative brick? xD I've just marked the location of the bricks as the pictures are quite large to post them.

20:10 12:6 3:4 22:3 25:2 32:1 Reasons why: 20 - Backhoes are my favourite and this one has many design features true to the real world counterparts that unfortunately 8455 lacked. 12 - Polished out to the last detail. Basically ready to be packed into a box and sold. :D (Would give it 9 points if I could) 3 - If one more function was added that thing would explode. xD Simply stunning how compact it is. 22 - Simple, powerful and sexy. Looks like a lot of fun. 25 - You don't see that every day. Interesting choice and very nicely executed. 32 - Nice basic chasis. It has a lot of potential to be aestetically upraged to fit any era.

Now that I've rewatched designers video of the Tumbler ( https://www.youtube.com/watch?v=riPTENi587w ) presenter sad tires will be introdced for the first time. My mistake ^^' P.S. ...now back to the man subject. ;)

I guess parts have to be made in large quantities for them to pay off and since sets with "exclusive" parts are in most cases are expensive ones this "one time deal" of "exclusiveness" would never actally pay off. :/

Tumbler tyres from 76023 set were also exclusive but here we have them repearing again in last years Drag racer set 42050 :P

That jet looks like F-35 with a bad paint job. :D Since it's has power functions maybe it will be capable of doing something like this:

Boat, BMW bike and Container transport machines look really nice. Color variety and combinations definitely make them more life like, unlike second half of the sets that are more or less two toned. :)

Nice pictures. :D Seems like that turning knob on the B model can't be placed on the other side of the axle because it would interfere with the bucket bellcranck. :/

That was my initial tought too, but it seems like this mechanicm is some kind of a "claw" so I suppose it doesn't affect it's main purpose that much. Unless that atachement is used as a fork(lift). Worst case scenairo is that you put that knob on the other end of the axle.

In demostration video it can be clearely seen that steering wheel is connected to some sort of "clutch gear assambley" situated in the middle of the drivetrain, so I supprt this theory.

That Xerion wheels and steerig could be the solid foundation for JCB 4CX backhoe loader. Not to mentin uprgraded pnaumatics. Unless someone mods the set maybe next year 8455 finally gets a decent successor.

Outriggers are definitely not fasionable but I like different design approach. They are compact, easy to deploy, and safely lock in place. This desing has great strenght necessary to hold all that weight.

Judging by the box art (or the lack of space to add new pictures/information) I would agree on that one. We are probably overthinking the whole subject. As far as new pump design goes I would say that new pump has sping encapsulated in the piston to prevent any "catching"...for smoother operation.
