I purchased these for a Takeuchi TL8 to plow snow on a 10 % grade driveway, which is pretty much solid ice base.It was a big improvment over nothing in the stock tracks.They do look like they stayed in after the first use.

My 2015 Skidoo Expedition has over 4000 miles on it all with Maxigrip 25mm studs. Out of 200 installed on the new sled, I have lost two. I am very happy with the performance to date and I would install these on future sleds rather than traditional picks. The traction may not be as good as traditional picks but they do not seem to wear the inside bogie wheels. My two other sleds with picks have required new bogies after 5000 miles.

My Skidoo Expedition got the test last week on very icy trails in Northern Maine. I was impressed with the traction and was able to maintain control at high speed over glare ice on windy fields. It would have been a dangerous ride without the 200 25mm carbide screws.

I purchased 400 screw-in 25mm studs for my wide-track Skidoo snowmobiles. We installed 200 per sled in about two hours. We used a dab of Gorilla glue on the tips before installing them. The track came with pilot holes already on the 1.25" paddles so installation was easy. I had issues with the sleds on glare ice and these studs took care of the problem. The sleds are much safer and having just a little traction makes a big difference on the lake when towing a load. I expect them to last the life of the sled because only 3mm is exposed above the paddle. They should not pull out and the glue was just added insurance.

I have a 2011 Cat. 279C Compact Track Loader. I tried to use this rubber tracked machine for snow removal, but the first time out, I found out I couldn't move on ice. I wasn't doing much better on hard packed snow. I didn't have $3600.00 to buy new tracks that are made for snow. So I decided to give Maxigrip ice studs a try.
I installed 3 HM25 studs in each cleat of the tracks, for a total of 360 on both tracks. The install took Me about 2 hours with a 18 volt driver.
My first time out. I was plowing snow on top of ice, and the difference was huge. I wasn't slipping at all.
After My first 5 hours of use. I don't see any wear, or any missing studs.
The only problem I noticed is, not to spin in circles on concrete. they will leave scratches.
So far I am very happy with this product. They do exactly what they are supposed to do. They paid for them selfs the first time out, because of increased productivity.
