I added a second set of tire chains recently to the front wheels of our 2006 CAT 242B with the aim of improving traction. Previously I had only chained up the back two wheels.
All chains are the same design ... made up of heavy duty twisted “ice claw” cross chains mounted every 4th side chain link (see attached photos).
We recently had an 18” heavy snowfall so I was able to test out the 4-wheel chains during about 10 hours of snow removal.
I use an 8 ft wide Virnig Snow Bucket for snow removal on 3/4 mile of gravel driveway, 1/2 mile of hiking trail, 1/2 mile of pasture feeding path and a few other gravel parking areas around buildings.
Our terrain is a combination of low to moderate hills and some flat areas. Roads are mainly raised profile.
Snow removal typically consists of plowing with the snow bucket, then pushing the snow off the road and dumping into piles.
I noticed a marked improvement in traction with the 4-wheel chains resulting in:
- An increase in the amount of snow I could push
- Significantly less wheel spinning in all operations
- Being able to remove snow from a ditched area where previously with 2-wheel chains I did not have enough traction
- Avoiding getting stuck when backing out of ditched areas. When using 2-wheel chains, I would occasionally not have enough traction so I had to “bucket back out” of the ditch.
As previously discussed in this thread, some HEF members have noted that using 4-wheel chains results in reduced stress and wear to the drive system.
Now that I have experienced using 4-wheel chains in heavy-duty snow removal, I agree that 4-wheel chains seems to reduce the drive train stress.
My recommendation … if you find you are spinning and getting stuck using 2-wheel chains, going to 4-wheel chains will provide better traction and reduce the stress on your drive train. If you are getting sufficient traction with 2-wheel chains, going to 4-wheel chains is not likely required.
