Nice! This will be an outstandig feature If want an additional challenge - or maybe in case that the variable floor is not possible: the reel can be moved forward and backward as well, to fit to the table position and the different grain conditions...and there is usually a horizontal knife for harversting canola as on the picture below. The drum package looks really good - and the panels below are offering a realistic shape! Maybe one idea for an improvement - without giving you a technical idea how to solve this: the biggest drum in the middle transversal bars across the machine instead of teeth. Maybe you have an idea to give it a nice shape? The current drums look a little bit like a "shredder". The rotors look brilliant. Especially that you somehow managed to put two rotors into that narrow space. The driveline is from the backside of the rotors - because in reality there is no space for gearboxes or PTO shafts in the front. Maybe you can put some kind of "return floor" below these sieves. Of course an active movement of this floor will be difficult - but close to reality! 100% agree...it's usually pneumatic suspension for this class of combines. Keep up that brilliant work and have a nice Christmas Time!!

Yes, the rearwheels are the drive ones. The frontwheels of the Terratracs are only "rolling" (as well as the midroller) but of course necessary to have enough tension on the belt and keeping up the friction between the wheels and the belt. Therefore the wheels are pushed to the outside with hydraulic cylinders. Yeah i agree - the belt will be the problem, especially if you want to have the belt moving. A Vario header will be cool - i'm a little bit afraid how to move the table to the front without opening a hole in the table. In reality it's build with overlapping sheetmetal, which is pushed out by hydraulic cylinders and then pulled back by gas pistons. But i'm sure, you will find a way :) In the existing mod of kneisibricks he created a Cerio header with a rigid table. This is possible as well - but not in that size. The largest available Cerio header is 30ft - and this does not really fit to your setup with the foldable unloading tube. Totally agree - the threshing and separation mechanism is so complex in reality that i makes sense to focus on the main elements. In my opinion this is a working feederhouse with "transport function" to the three primary threshing drums (two threshing one transport drum) that are working 'cross' in the machine. Here you can seperate "the big from the small parts" with some kind of sieve. The big parts could be transported forward to the secondary threshing area - while the smaller parts fall through the sieve and can be transported to the grain tank with the eleveator you already implemented. The secondary threshing area with the huge lenghtwise rotors could be quite more difficult because of the pneumatic functions (you already mentioned) - so maybe just a conveying element to tranport the bigger parts to the straw spreader?! I know, it's way more easy to talk about than building these functions :D

Wow, this concept looks really cool so far. I’m following this topics for a few weeks now as a guest. To be honest, I’m not so familiar with the building process – it’s more than 20 years now, that I build the last model. But I’m really familiar with combines – especially with this beautiful seed green products, so maybe I can add some helpful information. Gearbox and drivetrain: as 1gor and Jundis already mentioned, the LEXION has hydrostatic drive like the JAGUAR. The headland protection mechanism is only necessary for the JAGUAR machines, because it’s mainly made to protect the surface on grasland. Based on your description, you built a 4-gear gearbox with differential locking. That’s unusal for machines with TerraTrac. The have a regular 2-gear gearbox without differential locking system. In addition to that, 4-wheel drive is not a common option – it’s possible, but not often in the market. In general the 4-wheel drive is a complete hydrostatic solution, so no PTO shaft between front and rear axle. Maybe you can simplify this concept a little bit and get more space for your pneumatic function in the bottom of the machine? You asked for opinions on the planned pneumatic functions: to be honest I would skip this left panel / right panel / ladder functions, because they are not existing in reality. Maybe you can use these free switches to support the threshing functions (or driving the straw spreader). Concerning the header: what kind of header are you planning to build? At the moment it looks like a 40ft / 45ft header? A realistic option could be a 40 or 45 ft Vario header – or (and that’s my preferred solution) a Convio draper header (here). This fits to your large foldable unloading tube and I guess it looks quite cool with these belts in it and it could be more easy to build because of the missing header table adjustment, like the Vario has.
