Sizing
What size mixer wagon do I need?
Herd size on its own doesn't choose a model. Six questions do. Put your answers in the quote request and sales will work it through with you.
-
How many head are you feeding?
It's the starting point. With the ration and the feeds per day, it sets how big each load has to be.
-
What's in the ration?
Capacity is a volume, in cubic metres, so the ration decides the weight. A heavy ration asks more of the machine and more of the tractor.
-
What tractor will pull it?
A bigger wagon can mean a bigger tractor, so say what you're running now.
-
How many times a day do you feed?
Feeds per day decides whether one mix does the job or the machine goes round again. Two feeds a day out of a smaller wagon is a different job from one feed out of a larger one.
-
Pens or troughs?
Where the feed lands changes what the machine has to do at the end of the mix, so say whether it's going into pens or into troughs.
-
What height do you need to feed into?
Feeding into a high trough is a different machine from feeding onto a pad. Measure the height you need to clear and send it with the enquiry. Each model page lists its maximum unloading height with a three foot conveyor, and sales will check your figure against it.
Before you order
The tractor you need
Minimum tractor power runs from 65 horsepower for the 3040 to 220 for the 1240, and every model's figure is in the compare.

What's a vertical feed mixer?
A vertical feed mixer is a tub with one or more upright screws in it, towed behind a tractor, that cuts and blends a whole ration into one consistent mix. Every animal then gets the same mouthful instead of sorting the good bits out. It's the machine behind a total mixed ration (TMR), where the entire diet goes in together, and behind a partial mixed ration (PMR), where cows graze and the mixer makes up the rest on a feed pad.
Single screw or twin screw?
Single screw suits smaller loads and shorter mixes, and every Penta single screw machine sits under 15 cubic metres at the nine inch extension. Twin screw carries the larger tubs, mixes a heavy or long fibre ration more evenly, and asks more of the tractor. The change isn't only capacity, so send what you're feeding with the enquiry and sales will size it. Penta calls them single auger and double auger.
Is it delivered and set up?
Yes. A carrier brings the machine out. A technician sets it up, calibrates the scales and runs the operator through it. It's all included in the invoice price.
How full should a mixer wagon be?
Between 75 and 95 per cent of its rated capacity, which is the band Dairy Australia's national feedpad guidelines give for a vertical mixer. Below that the screws can't build a proper mix; above it the ration rides up the tub instead of turning over. Size the wagon to the biggest load you'll mix, not the average one.
What's the difference between a mixer wagon and a feed out wagon?
A mixer wagon weighs the ingredients, mixes them so every mouthful is the same, and feeds the ration out. A feed out wagon, silage wagon or bale feeder carries feed and puts it out along the fence, but doesn't mix it.
Vertical or horizontal mixer?
Every mixer wagon Valton Equipment sells is a Penta vertical mixer. One or two upright screws lift the ration and let it fall, which takes whole bales and long fibre without chopping them fine. A horizontal mixer works the ration along the floor with augers or paddles and suits shorter, pre-chopped rations.
