I have R4's that I've used for the last 4 years for snow removal. Also use 800 lb. rear ballast and an extra 180 lb. front ballast. I've had tractors with AG's and R4's but none work well on ice or a hard snow packed slope without chains. I adapted a 7' straight blade in place of the bucket to my loader arms one year, tried a 3 pt. snowblower, but ended up just using the loader bucket which works best for me.
