How is the Turning circle with all axles on the ground?

Only a few of 4000 parts are done

This is absolutely correct and follows the standard excavator controls.

this is the plan

Thank you very much. For all which are using the standard undercarriage. Does it drive better ore worse on carpet than in the vid?

With two C+XL at 1:1 gearing the speed is satisfying Edit:

With the orange yellow Liftarm, the green button will be pushed. edit: 2 XL with 1:1 gearing instead of 1 XL with 12:20

Undercarriage version 4 Hopefully it drives better than V3

Doesnt have a idea how much parts this boom has. it is even not final yet.

moving the front sprocket a half stud forward was a good solution on my undercarriage. The Mainboom seems to need a second motor

My face shovel? Two xl actuators are enough to push the liebherr around while digging. On the Backhoe we will see... edit: same reduction as in the set.

@rathodsandeep The prizes at amazon are daily prizes. They changes sometimes more than once a day. Check Brickmerge (< link) for finding the best prize.

Not mde yet, is this neccessary for a play model?

The first Digg of Pins will tell what is possible

The simpliest one is 1 stud thick, round and 2 studs long when you dont need forced trailer steering.

Brick controller 2 is able to do this.

I have a question: Is this digging depth enough? edit:

In original it is to reduce space while moving.

there is room for two V16

small progress, but nothing final.

Seems to work, but the stick looks still unfinished.

Lets go to give a backhoe boom a try Backhoe boom stick by Michael Wirth, auf Flickr edit 42100 backhoe bucket by Michael Wirth, auf Flickr Not Tested Yet. Order on your own risk https://www.shapeways.com/product/L4K4Z5TKS/backhoe-bucket-for-42100

Yes, only the last part on the picture, the yellow pin with pinhole is an error. they are included in the set.

The Partlist with the extra parts for the modified boom is available and hopefully comnplete https://rebrickable.com/mocs/MOC-30260/efferman/modified-face-shovel-boom-for-42100-r-9800/#tab_bi
