The model is made in 18 scale, the details are divided so that there are no problems with printing (with the size of the printing platform). A text document is attached with the files explaining some of the assembly points, the dimensions of the metal shafts are also indicated and all drive pulleys are numbered. I tried to make it as close to the original as possible.

• self-propelled, radio-controlled model
• pistons are running in the engine (which creates sound. The pulleys and the fan on the engine are also movable.
• the keys of the straw man are moving from behind
• the side pulleys of the drives are moving - the conveyor of the inclined chamber is moving
• the reaper is fully movable (reel, auger, scythe)
• there is a mechanism for lifting the reaper
• the piggy bank will open
