Built to grind. Built to last. Since 1966!
Commercial tub grinders and bale processors for feed, bedding, and biogas. Built in North Dakota. Sold and serviced in 20+ countries.
Small chop.
Big performance.
Real profit.
The right particle size changes everything. Set it with the screen. Hold it with the Big Bite hammermill. Bank it at the end of the season.
Precision.
You choose the chop length. Swap the screen, and the Big Bite hammermill delivers the same consistent cut, bale after bale. No drift. No sorting. Every particle the size your nutritionist specified.
Performance.
Consistent pre-chopped feed means faster mixing, better rumination, and more from every animal. The machine performs too: more tonnes per hour than anything in the field, from Siberia to Saudi Arabia.
Profit.
Better nutrition means more milk and more beef. Your TMR mixer finally works as a mixer and lasts years longer. And a HayBuster holds the best resale value in the business: plenty still running after 20+ years.
Three materials. One machine.
Hay & Straw
Round bales, square bales, loose, ground evenly for consistent nutrition, soft bedding, or feed mixing.
Grain
Corn, sorghum, and all cereal grains ground to exact particle size for optimal digestion and nutrition.

Biomass & Biowaste
Manure with long straw, old bales, corn stalks, rice straw, chopped so it feeds through biogas reactors.

60 Years of Published Research
Six decades of peer-reviewed science behind why mechanically processed forage and biomass outperforms unprocessed material. This isn’t marketing. It’s published data.
Daily milk increase per cow with optimized forage particle size
Improved feed efficiency with proper bedding management
Per head savings over winter with processed bedding
Methane yield improvement with reduced particle size
Built for Your Operation
Dairy
Optimized particle size for TMR consistency, transition cow health, and bedding that keeps SCC low and milk premiums high.
Beef & Feedlot
Process hay, cornstalks, and crop residue into consistent feed cattle clean up with less waste and better gains.
Biogas & Biomass
Smaller particles mean faster digestion, higher gas yield, fewer floating layers, less wear on pumps and agitators.
Custom Contractors
Built to grind commercially. 30+ bales per hour, day after day. One operator reported 95% of customers become repeats.
Farmer Tested. Farmer Approved.
Real words from real operators. No scripts, no actors. These are the people who run HayBuster equipment every day.
If you want the best, buy a HayBuster. All the rest don’t even compare with it.
The chopped straw from the HayBuster is exactly the material we need. Better than anything else we’ve run.
We’ve had our HayBuster for 25 years, on our second machine. A very solid machine.
Watch It Work
No script. No production crew. Real machines, real operators, real jobs getting done.

Joe Anderson Started It All in 1966
In 1966, Joe Anderson, a farmer in Jamestown, North Dakota, got tired of watching feed go to waste. So he built his own tub grinder. It worked so well his neighbors wanted one too. Sixty years later, HayBuster runs in 20+ countries across 300+ dealer locations. The machines are bigger, the engineering is better, but the idea is the same: build it tough, build it simple, build it to be passed down.
