Horsch co 4 updates

[Fish]

I thought I'd show a few photos of our latest project, which is to convert this old co to dd, to convert the fan to hydraulic drive and at the same time replace the head stock with an updated one + we may try and fit a dry fert tank.
So far we have remove the markers and fix all the worn out bearings and seals, all 12 of the centre wheels had to be done + a full set of metcalf openers fitted.
I wil post other photos as we progress, if anyone is interested.

Looks interesting, I’ve bought a co4 myself this spring and I am looking to convert to possibly metcalf openers. How much are they roughly I’ve never been brave enough to ring for a quote.

Watching with interest. Are you planning on updating the rear wheel axles? Looks like you still have the white plastic wear block system.

fully enclosed seed boot. Does away with the seed tube that wears away in no time.

Looks great

No seed bouncing out, no plugging, dap tube at the rear. No swapping to beans either, suits larger seed too. Uses the metcalf point.

The Metcalfs are around £70 each, compleat, as I'm only 15min from their workshop I just picked them up.

No plans to upgrade the wheels, as of yet.
The new headstock should be ready by sometime next week. I think fitting a dry fert tank will be the challenge, l have some ideas but I will have to build a new Venturi.

Looks interesting, but I think we will stick the Metcalfs as is for the moment. I have a neighbor who has run Metcalfs on a Sprinter for 2/3 years so I'll be guided by his experience for now.

Got a bit further with this today, fitted the new head stock.

Gone for 2.5inch Dutch openers in the end. Hopefully ive made the right choice

The advantaged of a hydraulic fan is that the fan speed and the tractor forward speed are completely independent, as is engine rpm + I hate ptos with a passion.

Actually, looking at your new swivelling headstock it would be harder to accommodate a pot fan anyway.

That's the plan, no way back now.

@Fish Any developments on dry fert tank? Also did you home make the headstock?

I put the 1 inch Dutch on mine, but it needs something to put soil back in the slots. I am going to put a row of tines in front of the press wheels as the discs only do the back row of openers. I will also put a row or tines after the press wheels.
Only use mine for beans notill.

Er no developments re the dry fert tank, but we have ideas how to do it, just need time.
The front headstock, the bit that the tractor arms mount to is from a horsch pronto, the mounting is home made.

The drill today

h. Hydro fan fitted, not painted yet, but tested, runs perfectly, no vibration at all, even up to 5500 rpm.
We can get 4000 @ 21 ltr/per min.

Did you modify the existing fan with a motor or did you find a new fan? Looks a cracking bit of kit though!!
