We are discussing grinding our high moisture corn with our claas 940. Anybody do this?
How are your tons\hour or bu\hour?
How fine can you roll 30% corn?
How do you get the corn in the machine?


We have tried snaplage\earlage in the past and didn't like it as much as HMS for a variety of reasons. Space\quality\mold\compaction in field.

We currently grind with a haybuster 1100 tub grinder and can do about 1500 bu per hour but are hoping to get more through per hour this year.

Any other suggestions are appreciated.

Used to work at a Claas dealership and had some customers do this. Some observations.

Unless corn is harvested wet 25% or higher, the machine will not grind very fine unless you change to fine rolls.

Dry corn is extremely hard on the machine since it acts like a sandblaster on all components and wears things out very quickly.

It makes a very big mess of everything - machine will leak corn all over, the rads will become full of dust, the dust from the corn will blow everywhere on a windy day.

Where I currently work, we use a haybuster 1130 and it is slower then a chopper but much easier to control the product coming out and there are less messes and fewer whole kernels.

The other thing to consider is that you are using an extremely expensive, higher maintenance machine to do a job it was not really designed to do.

A haybuster is relatively cheap and parts are definitely cheaper.

As far as capacity, if it is set up right and you build a proper hopper to feed the machine with an auger, the capacity is very high-probably 1.5 times of a haybuster.

Well we ground a couple of truckloads of 35% corn with the chopper. I rigged a temporary front hopper out of 2 barrels and 4 ratchet straps.

We were grinding at a rate of 2400 bu per hour and the machine was at 10% engine load. Could have gone faster but for limitations of lift auger and barrel hopper system.

No doubt it is expensive and dirty but hay buster isn't free and neither is the tractor needed to spin it. That being said we are going into the season planning on using the hay buster 1100 again. we have also lined up a demo of a roto grind gg10.

Keep the Claas & Barrel combo waiting in the wings, just in case.
