I bought this grinder a month ago as I was clearing some land to put a shop in. Also, I have plenty of more stumps to clear on my 4 acres. I have a Kubota LX2620 so nothing to big, but I am delighted with how well this grinder takes out even large stumps. Freshly cut trees takes a bit longer, but it gets the job done. Besides my grapple, this is now my favorite implement, and I would recommend it to anyone. I have taken out at least 30 stumps so far and love being able to do it without hiring it out. I did put in a 10ackup camera which works pretty well on bigger stumps when you start. But as you get deeper and the area gets covered in sawdust you will need to turn around and look. I am really delighted with this purchase.

I’ve already did about seven stumps and it’s probably already paid for itself. You might want to bring an RC cola and a moon pie it’s not the fastest thing in the world but it’s definitely vastly less expensive than hiring it done. It’s nice to sit in an air-conditioned cab and watch what’s going on I also purchased the camera you have to have a camera the one I got is solar powered and one charge last 25 hours. I’m very happy with the unit it did stall my tractor out four times until you get the hang of it you can’t take very big bites but it works phenomenal and if I had to do it over again I would buy it again

Arrived quickly, well-packaged for shipping, and as promised. This is a quality, well-built machine!

This thing is a beast! The stump in the photos took about 1.5 hrs because of the giant root system it had. This is the biggest and most complex one so far. In six days I have eliminated 127 stumps on our property. I would definitely encourage anyone on the fence over purchasing the SG24 that they will not be disappointed.

The stump grinder looks very well made and arrived in excellent condition. Will not be using till this coming spring but I don't expect any problems.

This stump grinder works great and is well made. So far I’ve used it to grind 5 large Bradford Pear stumps and it has worked very well. The stump in the picture took 24 minutes to grind and it was roughly 28 inches in diameter.

Unit arrived in excellent condition. Freight shipping was rather fast. I chose to pick it up at the fedex freight terminal which was easy. I have mounted it and still need to shorten the drive shaft and install it. Unit is built super heavy duty. Thank you Mechmaxx

Ordering was easy. Paid extra for piece of mind shipping. Scheduled for a certain date and time. It showed up 3.5 hours early, luckily I had taken off of work to be home. The stump grinder works great. I have ground around 20 stumps so far.

Very impressed, ground an oak stump that measured 6 foot at it's widest. Even ground the rocks that was in the stump. No chipped carbide teeth, still sharp.

Finally getting around to a Follow up review… I’ve only had the opportunity to grind a few of the stumps that I need to but this grinder doesn’t disappoint… you could pay more from someone else but I’m very impressed with the quality of the mechmaxx so far… the first stump I tried was 38” across made quick work of it… probably only took me about 15min I’m already planning my next purchase from mechmaxx…

I bought this on sale even before I took delivery of my tractor and it has easily paid for itself already after the first weekend of use. Smaller stumps that have been plaguing grass cutting were taken out in a matter of minutes. I did not expect to be able to grind one of the larger stumps in the yard, which was about 3 feet in diameter and sticking out about 18 inches above the ground. In addition, the root system was about 12 feet in diameter and was above grade by about another 18 inches near the center of the stump. It did take a while, but I was able to completely level the area, once again making it easier for grass to grow and to mow across even ground. Assembly was very simple, the shipping was quick and efficient, and the equipment feels very solid like it was last a very long time. I did not have to do any trimming/adjustment to the driveshaft for my 2025 Kubota L2502, and the clutch adjustment was simple with clear instructions. Couldn’t be happier with this purchase.

I had low expectations. Hoped to knock out all the little stumps so I could get the big ones done in a one day rental of a “real” stump grinder. I didn’t expect to install it and then proceed to grind out 5 stumps in about two hours! 3 of the stumps were 2-3 feet across at ground level. Simply an awesome machine! I expect to grind out a huge maple stump tomorrow. Incredible value for $1399!

I am very impressed with the stump grinder, great value for the price, very well made, but i think i am more impressed with the customer support they have been helpful, responsive, and have really shown me that they are willing to go the extra mile for their customers.
My short video shows how smooth this thing is on my Kubota BX2380

After debating about it for a week and watching videos on YouTube about it. I Pulled the trigger on the SG24. Took about 10 days to receive once I ordered. Sales dept was quick to reply with any questions about product and ETA on shipping. Once arrived it was packaged very well. Took about 2 hours to fully assemble. Directions are very clear. Installed it on my Kioti 3510 w/quick hitch. Didn’t have to make any adjustments on PTO shaft. Fits perfectly. After testing it out on a few small stumps. Knocked out a 25” oak stump in 45mins Definitely invest in a rear camera it helps not having to stay turned around constantly. Your back and neck will thank you guaranteed. Best one on Amazon is $39. Already knocked out 15 stumps in 2 days. Everything is smooth and tight. Cutters are still sharp. Definitely would recommend this MechMaxx stump grinder to anyone. Definitely worth the price. Thanks for a great product and customer service MechMaxx!!

Put this on our Massey Ferguson 25 hp tractor. Take it slow and steady. Works great! We've had this for a year now. Taken out about 6 small (1-2 ft diameter) and 5 large (3-5 ft diameter) stumps. Still works great.
