Mulches leaves great, very heavy duty and fit the bolt pattern correctly.

If you need a good cut with heavy damp grass. I'm talking 3 foot tall and DAMP I bought these blades because they looked very serious about their task. Have no doubt about it these blades are the bomb, just downright mean. I put them on My Wife's Poulan 19.5HP42 Riding Mower that's 11 or 12 years old. She's TOUGH ON EQUIPMENT!!! This makes 4 sets of blades I've installed plus replacement of one of the blade spindle assembly as well as making custom steel reinforcement plates to backup and strengthen both blade spindles to deck mounts because She kept breaking them !!! I've seen Her do a wheel stand resulting in the mower 90° nose up after getting caught on a Dog Run Line that caught the steering wheel but that's a whole other Rodeo. These blades sliced right through the 3'+ tall grass that has been wet/damp for weeks due to weather, mulched it finely and spit it right out of the discharge chute like it was 2" long and dry when cutting !!! I used to keep a spare set of blades on hand because She would go through them like at least one set per season. I don't think that I will have to keep doing that with these blades. They are much thicker (+ .015") than others. I HIGHLY RECOMMEND THESE BLADES EVEN FOR NORMAL USE. If they ever need to be replaced I will be buying the same ones for sure.

These blades are noticably thicker than most, and they are Made In USA. I am very pleased with these blades.

The blades fit perfectly and when I used the lawn tractor to cut high grass they cut cleanly and mulched so well I didn’t have to rake afterwards.
