I replaced my 580 with a 590. The bushels harvested by each machine were the same but wornout items on the 580 were new on the 590 and I needed the stronger hydro in my hills. I am always in pursuit of better seed quality and higher throughput in my seedbeans. This cylinder is from Precision Farm Parts. Notice I arranged the bars in the middle to split the flow. I ran one in another 590 last year with good results. It runs smooth and quiet. The concave is from HHS and allows for easy concave element changes similar to the APS grates.

Tiger I am surprised how little wear your impeller has. Mine was wore pretty good in the center and I built up the tip of the "v" so it was the same height as the wear plates I put on.

Haven taken all the guts out of my machine it would have been nice to not work around the tires. With how wet it is it would be a good year to have tracks.

Wait......what? Sorry to hi jack the thread but is that an access to change the main concave in sections from the side in that pic? Or am I just seeing things?

Yes and no. The view you see is from the right side of the machine with the cylinder removed. This is where the cylinder drive pulley would be. To remove the factory concave is time consuming, but not very hard. It involves pulling the feederhouse. Luckily, the APS grates are easily accessible to change.

The concave pictured is a new design from hhsparts.com . It allows the front portion of his concave to be easily modified via the left access hole using the same APS grates.

Okay I see, I'm sure that removing the main concave would be time consuming. That is one major advantage to the rotor machines. Thank you

The HHS interchangeable concave is great, I love mine it really makes the Lexion an all rounder, in our conditions anyway and especially with the terra tracs, tyres would be a pain though.
