The inclusion of a chain drive system, which is often preferred over gear drives for its ability to handle shock loads, is a notable design decision. For a more direct comparison of attachment features, read our article on maintaining PTO attachments. Now, let’s see what you actually get in the box.

The MachMaxx CM5 arrives in a large, heavy crate. Inside, you will find:
The packaging is robust, and we noted no damage upon arrival. The first impression of the build quality is very positive; the welds look clean, and the powder coating is thick and even. One minor note is that you will need to supply your own gear oil for the chain case, as it ships empty. This is for should I buy MachMaxx cement mixer considerations, ensuring you don’t need to purchase extra tools immediately.

First, attach the mixer to your tractor’s three-point hitch. Align the lower lift arms with the category 1 or 2 pins and secure them with lynch pins. Attach the top link to the upper mounting point and adjust it so the mixer sits level when raised. Next, connect the PTO driveline to your tractor’s output shaft, ensuring the length is correct. Secure the safety chain to the tractor frame. Finally, fill the chain case with the recommended gear oil (typically 90-weight) before any operation.
Before adding any material, run the mixer empty for about a minute. This checks for any binding and lubricates the new gears and bearings. Start the tractor at idle, then slowly engage the PTO. Listen for any unusual noises. Confirm that the drum rotates smoothly in the mixing direction. To verify the dump function, raise the 3-point hitch and tilt the drum using the release lever. Then, lower it back to the mixing position by pulling the lever again.
To mix concrete, start by adding approximately half of your required water into the rotating drum. Then, add your gravel, sand, and cement. Allow the machine to mix for 2-3 minutes. If the mix is too dry, add more water a little at a time through the 18-inch opening. Our testing showed that using a MachMaxx CM5 vs alternatives in terms of loading ease, this wide opening is a major time-saver. Once mixed, stop the PTO, position the drum over your wheelbarrow, and pull the dump lever. The mix pours out cleanly, though you may need to tap the drum with a rubber mallet to clear all material.
For perfectly consistent mortar, pre-wet the drum with a small amount of water before adding the dry mix. This prevents the dry powder from sticking to the paddles. When mixing large batches, avoid overfilling. A 5-cubic-foot drum typically handles 4-4.5 cubic feet of mixed material efficiently without splashing. For rapid unloading on a continuous project, you can leave the drum rotating at idle while you move to the next pour location. Read more about how to maximize efficiency in our concrete project guide.
After each use, always clean the drum immediately before the concrete hardens. With the PTO running, add a few gallons of water and let it slosh around. Then, dump the slurry. For stubborn residue, use a masonry hammer to knock it off inside the drum. Lubricate the PTO shaft universal joints and grease points on the hitch every 20 hours of use. Check the gear oil level in the chain case monthly. Store the unit under a tarp or in a shed to protect the powder coating from prolonged UV exposure.

We spent three weeks testing the MachMaxx CM5 on a 25 HP compact utility tractor. Our testing included mixing five separate batches of standard 3000 PSI concrete for fence posts and two batches of mortar for a brick barbecue pit.
Mixing Speed: From dry ingredients to a uniform, workable mix took an average of 3 minutes. This is remarkably fast compared to a standard 3.5 cu-ft electric contractor mixer. The consistency was excellent, with no dry pockets observed.
Efficiency: We were able to pour a continuous footing for a 20-foot fence line in just over an hour, including mixing, transport, and pouring. This would have taken a full day with manual mixing.
Durability: After 20+ batches, the paddles showed minimal wear, and the powder coating held up well against the abrasive concrete.
In our primary test for a fence foundation, the mixer’s ability to travel on the three-point hitch was a game-changer. We drove directly from the aggregate pile to the hole, mixed on the spot, and poured directly. This eliminated multiple wheelbarrow trips. For the mortar mix, the consistency was perfect frothing, easier than mixing by hand.
MachMaxx claims the CM5 saves labor. After our testing, we can confirm this is not an exaggeration. The MachMaxx cement mixer pros cons discussion is heavily weighted towards pros when it comes to labor savings. The only gap we found was the manual’s suggestion to run the mixer at 540 RPM. At this speed, the drum rotated too fast for some mixes, causing splashing. We found 400-450 RPM was more effective. This minor adjustment turned the machine into an excellent performer.
In the market for a tractor PTO cement mixer, the CM5 competes primarily with models from brands like Agri-Fab and a few lesser-known importers. Here is a quick comparison:
| Feature/Spec | MachMaxx CM5 | Agri-Fab 45-0383 | Generic 4 Cu-Ft Mixer |
|---|---|---|---|
| Drum Capacity | 5 Cu-Ft | 3.5 Cu-Ft | 4 Cu-Ft |
| Hitch Categories | 1 & 2 | 1 | 1 |
| Weight | 322 lbs | 200 lbs | 250 lbs |
| Construction | Powder-Coated Steel | Painted Steel | Painted Steel |
| Price | ~$1,799 | ~$1,000 | ~$1,200 |
Choose the MachMaxx CM5 if you need a heavy-duty unit for frequent, larger projects on a farm or commercial property. Its capacity and build quality justify the higher price if you are mixing concrete weekly. It excels in scenarios where quality and speed are paramount.
Consider the cheaper Agri-Fab if you only do occasional, small-scale projects like a few fence posts per year. The lighter weight and lower cost might be better for a smaller budget. The MachMaxx CM5 vs alternatives comparison highlights that the CM5 is an investment in professional-grade capability.
Do not fill the drum to the brim. A 4 to 4.5 cubic foot batch mixes more efficiently and reduces strain on the tractor’s PTO. This improves both mixing consistency and component longevity.
Always clean the mixer over a dedicated washout container, not on the ground. The concrete slurry is highly alkaline and can damage grass or contaminate soil.
For positioning the pour, a heavy-duty contractor-grade wheelbarrow is essential. Consider a model with MachMaxx PTO mixer worth buying accessories for smooth movement.
When you are ready to pour, take a moment to gently rock the drum back and forth after stopping the PTO. This settles the mix and prevents a big lump from falling out first.
Always reinstall the PTO shaft guard after connecting. It may be annoying, but it is critical for safety. Ensure the guard rotates freely and is not binding on the shaft.
Do not dump all the water in at once. Add half, then the aggregates, then the cement, and then the remaining water. This prevents dust and ensures better hydration of the cement.
Plan your pour layout. Position the mixer near your aggregate pile, mix, then raise the hitch and drive to the pour site. This is the single biggest time saver over other methods.

You will need a standard tractor with a Category 1 or 2 three-point hitch and a rear PTO. You also need wheel chocks or a level surface for safety. We recommend purchasing a heavy-duty wheelbarrow for moving the concrete, a rubber mallet for tapping the drum, and a concrete washout bucket. Also, buy gear oil (90-weight) for the chain case.
MachMaxx offers a one-year warranty against manufacturing defects. Their customer support is reachable via phone and email, and we found them to be helpful. The warranty covers the drum, frame, and PTO driveline but not wear items like the chain or mixing paddles. It is a standard warranty for equipment in this price range.
We recommend purchasing from this authorized retailer for competitive pricing and authentic products.
While compatible with 20-30 HP tractors, a compact utility tractor in the 25-30 HP range with Category 2 hitch arms is ideal. This provides enough lifting capacity and hydraulic flow for the 322-pound attachment. Sub-compact tractors on the lower end of the HP range may struggle, particularly on uneven terrain.
Yes, it is very effective for stucco and mortar. The consistent mixing action is excellent for these finer mixes. For stucco, make sure the drum is clean before use and maintain a slightly slower speed to avoid splashing. The large opening makes it easy to add water in controlled amounts.
