Any updates on this moc? I'd love to see the completed bodywork and how it all fits together! -
I like it!

Green tractors need love too.... ;)

I would have liked to use two pumps to speed up the steering, but there just wasn't any room left. Initially the steering was going to be done by 2 small linear actuators, but I just couldn't find any setup I liked, and they wouldn't pivot freely in all directions. There was also an autovalve in place to shut off the compressor, but it was unreliable and too slow to act so I just left it out.

[MOC] Crane Truck

Absolutely beautiful moc with very well executed features. Love to see huge models like this. -
There are many good ways to do suspension, and a lot of them don't use the standard shock absorbers. NicJasno has some excellent designs that use 1x and 2x plates to simulate leaf springs, and there are also walking beam type suspensions that allow full axle movement but don't move up and down so much, which is perfect for a big heavily loaded truck. As long as all the wheels stay on the ground all the time, the suspension is successful.

Thanks again for all the kind words! I_Igor, I really like your tractor too, and using turntables for the tracks looks just right for it.

Here are a couple of hitch ideas, first an articulating hitch for towed equipment. It pivots in all directions and requires no mods to the tractor: And a 'quick hitch' type attachment for things that would normally go on a 3 point hitch:

Here is an implement fitting for a tractor this size, a large pull-type scraper. This one is based off of an Ashland 215, which has a 21 cubic yard capacity. It pivots where the tongue attaches to the pan and has a sliding ejector to push the dirt out once it is full. The hitch pivots and swings in every direction and is very similar to the ones currently used on real scrapers. Cutting edge with spoil door, which lifts when the ejector is pushed forward. I needed more travel than one cylinder would provide, so I paired a V2 cylinder with an older V1 with some 3x5 arches: Ejector all the way forward: Rear view with push bars and hitch point for another scraper: Thanks for looking!

Thanks all for the kind words! The hood was one of the toughest parts, since the real one slopes, forward, down, widens, slopes, and narrows but I think it turned out fairly nice. Agrof, I definitely wanted to do stickers, if I could have found some at the right scale, they would really make it look complete. I will try to have some implements coming soon! Brick_Sticker

Mechanical Chain Counter

This is an excellent idea, could also be used for displays in a moc, such as a gas pump or an odometer. -
Thanks, I have a few ideas for some implements, this tractor definitely needs to be put to work!

Hello All, Since we now have tractor tires, let's build some tractors! Here is my version of the Case 620 HD farm tractor, rated at 620 hp and designed for large farms: First, the real thing: Now the Lego version: This tractor features 4 pneumatic remotes, as well as pneumatic steering controlled by a servo and switch. Other features include seperate PTO, drawbar, recovery cable, opening hood and pivoting center section. It is driven by one XL motor, and the pto and air pump are powered by M motors. There wasn't room under the hood for two receivers, so an sbrick is used to control all functions. Additional pics: Short video clip of steering: Thanks for looking, other pics and LXF file are available at http://www.brickshelf.com/cgi-bin/gallery.cgi?f=568801 Brick_Sticker

Looks good, I like the bull bar on the front especially.

It happens to me as well on multiple browsers and devices, but only in the threads. If I click on a particular index, technic or otherwise, it will load each page properly when pressing next or selecting the page number. But in any thread, regardless of page count, pressing a button does nothing, and I have to select the address bar, hit enter, then it takes me to page I selected. No idea why, though.
