Concrete mixer attachments for tractors and skid steers span a 160-litre bucket that tips off a euro hitch to a 1.2m3 hydraulic drum that pours a shed slab in one batch, and picking the wrong drive type or mount stalls the job before the mix sets. This guide ranks what actually works on New Zealand tractors and skid steers in 2026, by capacity, drive type and mount compatibility.
- Sierra SCM350 PTO Concrete Mixer at NZ$2,995 is the best concrete mixer attachment for tractors under NZ$3,000 β Buy.
- Concrete Mixer Bucket 200L Skidsteer/Excavator/Euro at NZ$9,495 suits skid steers with standard hydraulic flow β Buy.
- Zagroda Concrete Mixer Hydraulic Drive 0.85M3 at NZ$11,995 handles bulk pours on tractors 45HP and up β Consider.
- 600L Hydraulic Pan Mixer Self Loading at NZ$11,295 saves shovel time on repeat farm pours β Consider.
- Skip stationary electric pan mixers if the job needs a true tractor or skid steer attachment.
Why this matters
Most concrete mixer failures on farms and lifestyle blocks trace back to a mismatch between drive type and equipment, not the mixer itself. A PTO mixer needs a tractor with a working three-point linkage and a rear PTO shaft turning at 540rpm; a hydraulic bucket mixer needs a skid steer or excavator with enough hydraulic flow to spin the drum without stalling under load. Get that wrong and the mixer either won't turn or burns out the auxiliary hydraulic circuit within a season.
Capacity matters just as much as drive type. A 160-litre bucket suits post footings and small pours; a 1.2m3 drum is built for foundation work and slab pours where batching by hand would take all day. Buying oversized for a compact tractor's lift capacity is as common a mistake as buying undersized for a job that needs volume.
How this list is ranked
Each concrete mixer attachment below is ranked on drive compatibility (PTO vs hydraulic vs electric), mount type (three-point linkage, euro hitch, skid steer quick-attach), rated capacity in litres or m3, and 2026 NZ pricing. Mount type decides which machines can run it at all β a euro-hitch bucket mixer won't bolt onto a straight three-point linkage without an adaptor, and a skid steer needs its own quick-attach adaptor to run euro-hitch implements at all.
Electric pan mixers are excluded from the ranked list β they're stationary workshop machines, not tractor or skid steer attachments, even though they show up in the same search results.
The ranked list
1. Sierra SCM350 PTO Concrete Mixer β the entry-level tractor pick
The Sierra SCM350 is a 350-litre drum mixer that mounts on a Category 1 three-point linkage and runs off the tractor's rear PTO at 540rpm. At NZ$2,995 it's the cheapest true concrete mixer attachment for tractors on this list, built for farm construction, fence posts and small footing pours rather than continuous batching.
It has no hydraulic requirement beyond a working PTO, which makes it the pick for compact and mid-size tractors that don't have spare hydraulic outlets. Verdict: Buy for lifestyle block owners doing occasional pours under 350 litres a batch.
2. Concrete Mixer Bucket 160L Skidsteer/Excavator β the smallest bucket option
This 160-litre C&F BMX160M bucket mixer bolts onto a skid steer or excavator quick-attach and runs off the machine's hydraulic circuit rather than a PTO. At NZ$8,195 it's priced for contractors who need to mix and pour in place without wheeling a barrow across the site.
The drum tips to discharge directly where you're standing, which is the whole point of a bucket mixer over a towed drum. Verdict: Buy for fencing and small footing contractors already running a skid steer.
3. Concrete Mixer Bucket 200L Skidsteer/Excavator/Euro β the euro-hitch all-rounder
The 200-litre BMX200M steps up from the 160L model with the same hydraulic-drive bucket design, but adds euro-hitch compatibility alongside skid steer and excavator mounts. Priced at NZ$9,495, it's the version that works across three machine types without swapping brackets.
That flexibility matters on properties running both a skid steer and a euro-hitch loader tractor β one mixer bucket, two machines. Verdict: Buy if the property runs mixed equipment and wants one mixer for both.
4. Concrete Mixer 270L Skidsteer/Excavator/Euro β the mid-size step-up
The BMX250P holds 270 litres, a meaningful jump from the 200L bucket for anyone pouring footings back-to-back rather than one at a time. At NZ$9,995, the price gap over the 200L model is small for the extra batch volume.
It keeps the same hydraulic drive and multi-mount compatibility as the smaller buckets, so the upgrade decision comes down to how many batches a day the job needs. Verdict: Buy for anyone pouring more than two footings a day.
5. Concrete Mixer 360L Skidsteer/Excavator/Euro β the biggest bucket mixer
At 360 litres, the BMX350P is the largest bucket-style mixer in this range and the one where hydraulic flow requirements start to matter β check the skid steer's rated flow before buying. Priced at NZ$11,395, it sits close to the hydraulic drum mixers below it.
For contractors already running a mid-size skid steer with adequate flow, the extra 90 litres over the 270L model cuts batching time on bigger pours. Verdict: Consider β confirm hydraulic flow first, otherwise the drum stalls under load.
6. Zagroda Concrete Mixer Hydraulic Drive 0.85 M3 β the wildcard for bulk pours
This Zagroda drum mixer runs hydraulically rather than off a PTO, with an 850-litre (0.85m3) capacity aimed at tractors 45HP and above with spare hydraulic outlets. At NZ$11,995, it sits above the bucket mixers on price but below the largest drum models.
Hydraulic drive means smoother, more consistent drum speed than a PTO mixer, which matters for consistent mix quality on bigger jobs. Verdict: Consider for tractors with the hydraulic capacity to run it.
7. 600L Hydraulic Pan Mixer Self Loading β the self-loading option
The self-loading hydraulic pan mixer from Zagroda holds 600 litres and loads its own aggregate via a hydraulic arm, cutting the shovel work out of repeat batching. At NZ$11,295, it costs less than the 0.85m3 drum mixer above despite the self-loading feature.
Self-loading pan mixers suit farms doing repeat pours over multiple days β the time saved on loading adds up fast once you're past the first few batches. Verdict: Consider for anyone batching daily rather than one-off.
8. Zagroda Concrete Mixer 1.2 M3 Hydraulic β the volume pick
At 1.2m3, this is the largest hydraulic drum mixer on the list, priced at NZ$15,995 and built for foundation-scale pours rather than fence posts. It needs a tractor with real hydraulic capacity to spin a drum this size without bogging down.
This is the mixer for a shed slab or a run of foundation footings in one session, not a once-a-year post job. Verdict: Buy for anyone pouring foundation-scale volumes regularly; Skip if the biggest job is a fence line.

Where to buy
Buy from a supplier that lists the mount type explicitly β euro hitch, three-point linkage or skid steer quick-attach β because a mixer photographed on the wrong mount is the single most common return reason on these attachments. Freight runs NZ-wide from Implements Direct, and the team carries over 22 years of experience matching implements to tractor and skid steer specifications.
Check the hydraulic flow rating on any bucket mixer before buying if the skid steer is older or a smaller model β an underpowered hydraulic circuit will spin the drum too slowly to mix properly. If the loader or skid steer runs a euro hitch and the mixer is three-point linkage only, an adaptor or a skid steer to euro hitch adaptor solves the mismatch without buying a second mixer.
FAQ
What's the best concrete mixer attachment for tractors in 2026?
The Sierra SCM350 PTO Concrete Mixer at NZ$2,995 is the best concrete mixer attachment for tractors doing occasional pours under 350 litres. For volume pours over 800 litres, a hydraulic drum mixer like the Zagroda 0.85m3 is the better fit.
Is a PTO concrete mixer better than a hydraulic one?
A PTO mixer is cheaper and needs no spare hydraulic outlet, making it the better choice for tractors without extra hydraulic capacity. A hydraulic mixer runs smoother at consistent speed and suits skid steers and bigger tractors already fitted for auxiliary hydraulics.
How much does a concrete mixer attachment cost in New Zealand?
Concrete mixer attachments for tractors and skid steers range from roughly NZ$2,995 for a 350L PTO drum mixer to NZ$15,995 for a 1.2m3 hydraulic drum in 2026. Bucket mixers for skid steers sit in the NZ$8,000 to NZ$11,500 range depending on capacity.
Can I use a skid steer concrete mixer bucket on a tractor?
Yes, if the tractor has a euro hitch or the correct adaptor fitted, since most skid steer mixer buckets also list euro hitch compatibility. A straight three-point linkage tractor needs a three-point-to-euro adaptor first.
What capacity concrete mixer do I need for a shed slab?
A shed slab pour typically needs a mixer in the 600L to 1.2m3 range to keep batch numbers manageable. Smaller 160L to 350L mixers work fine for post footings but turn a slab pour into dozens of batches.
Do concrete mixer attachments need a specific PTO speed?
Most PTO-driven concrete mixers, including the Sierra SCM350, are built to run at the standard 540rpm PTO speed found on most compact and mid-size tractors. Check the mixer's spec sheet against the tractor's PTO rating before buying.
What's the difference between a bucket mixer and a drum mixer?
A bucket mixer tips to discharge concrete directly from the machine, which suits pouring in place on a skid steer or excavator. A drum mixer, whether PTO or hydraulic, holds a larger batch and is built for continuous mixing rather than single-load discharge.
Is a hydraulic pan mixer worth the extra cost over a bucket mixer?
A self-loading hydraulic pan mixer like the 600L model saves shovel time on repeat daily pours, which pays off once batching moves past occasional jobs. For one-off footings, a cheaper bucket or PTO mixer does the job without the extra cost.
One last thing
The price gap between the 200L and 270L skid steer bucket mixers is only NZ$500, but the capacity jump is 35% β that's the best value step on this entire list for 2026. Most buyers who start at 160L end up wishing they'd bought the 270L within a year of steady use.
