I am building a simple root crops harvester attachment. The attachment has cutting discs in front of it to prevent weeds from jamming it. This is the almost finished machine.
The problem that I am facing is that the bearings I used are not stiff. That is, they tilt on the shaft axis along with cutting discs. I want the cutting discs to be straight. To counter act that, I can use 2 bearing as shown in the image below. The problem with this approach is that my shaft is pretty short (it barely fits 2 bearings) and I lose the option to position the disc left and right on the shaft.
How do plows, harrows or potato harvesters attach cutting discs? Is there a special type of bearing (and bearing housing) that prevents tilting? Should a bushing be used instead? Thank your for your answers.
