Combine concave replacement

[Chezza]

Running a Claas Dominator 108VX combine and looking into overhauling the drum and concave.
Rasp bars are worn out on drum, Concave is in straight order and would maybe do a couple more seasons but ideally want to change the lot.
Quite fancy the Hardox steel concave made by “combine fabrications”.
Apparently It’s based on the Australian “Nichols” concave. Doesn’t require a de-awner rasp bar at the start of the concave like our current setup has, Should this be a concern?

Price wise I’ve been quoted £2000 for this concave which is pretty much the same as from the local Claas stealers. Our concave is a wired one in 3 segments but the hardox setup would be a one piece unit based on the frame that supports the segments in ours. Has anybody used one of these concaves and are you pleased with it?

I had a Nichols concave in my old 204. It transforms a combine. Better thrashing so you can often have a wider concave setting, a result of that is better fuel consumption, better sample, less damage to the straw making the sieves work less hard and it’s stronger. If it’s the same price as a standard concave I’m intrigued to know why you’re even asking the question.

Concave and cylinder upgrades are a hot topic in the claas world here. Many choose to go with sunnybrook conclaves and cylinders as well as impellers if a hybrid and mot a walker machine. I gave the sunnybrook cylinder and it’s pretty smooth but have deep wide rasp bars which is great on beans giving less damage but in wheat I feel they are too wide. Going to change the concave this winter to a stronger design as the claas ones tend to bow in the centre. Watching this thread with intrest.

To replace the original knackered concave on a JD 2258 I put in a Nichols one. Really strong stuff, wires won't break, deals with maize well.
It's a no brainer!

Put a Nicholson concave in our JD for this harvest and the difference is amazing, as said above wide concave settings, better thrashing, less fuel and less straw damage and a better sample.

The lack of de awning plates concerned us initially but despite the year it's the easiest we've had for getting the awns off barley.

The Nicholson must weigh easily twice what the standard one does, the frame is so much bigger and the wires are twice the thickness.

We have one sat in our shed that was in a 108sl Maxi. We changed back to the originals as we missed being able to change the concaves for broad-bean seed. I’ll try and get some photos if you’re interested in it. It’s very well made!!

Replaced the concave in our New Holland TF78 with a Loewen concave seven years ago and have been very pleased. This make doesn't require deawning plates either. Don't need to have the concave as closed up with the Loewen. I told the corn carter that it could increase the combine output by 50% to which he replied that i would be waiting for his return 50% longer.

Here’s some photos of the one out of our 108. PM me if you’re interested in it.

If we're selling stuff, I have a heavy duty JD concave for a JD 1075 available!
Forgot I had it, I think it's almost new.
