Ok here is a new on on me... got a new set of blades for my Kodiak 5 foot brush hog... without giving it a second thought, pulled off the old blades and installed new one. Went to cut and they did NOt cut. Compared the new with the old and the new blade had the sharpened side just the opposite of what i have been using for 100 years. In other words, i had clockwise blades instead of counter clockwise. Never ran into this issue before. Anyone out there with comments about this ??? thanks.

Sounds like you put them on up side down to me.

No, there are forward and reverse rotation blades. My Hydraslide Hardee ditchbank cutter has blades sharpened on both sides. You can reverse the cut by swapping the hoses on the pump. You can buy the sharpened on either side or both sides.

do you have part # from Kodiak that you can price on Amz? have had surprisingly good luck on finding replacement parts that way. if the knives are reverse sharpened as you mention, you have a boat anchor unless refundable.
good luck

Check with someone that has a 15' batwing. A batwing mower usually has clockwise on one side and counter-clockwise on the other side.

If the blades are like mine then one would have a 25% chance of randomly installing the blades correctly.
1. Observe the direction of rotation while running.
2. Orient the blades so that the cutting edge is the lead edge.
3. Make sure the trailing edge of the blade is angled up so the blades act like a fan and lift the grass as the brush hog turns.
4. Go mow some grass and enjoy the day.
Example: If the mower deck turned in the direction of the arrow,
then “c” would be the correct orientation.

If you didn't want to buy new blades, perhaps you might look at the gear box on your cutter and see if the gear set can be flipped around. Many gear boxes are made that way for various applications.

This is common. It's even possible to have two directions for the same mower. My 10ft has the same gearbox left and right, so they accommodate for this by having opposite-sharpened blades on the left side. Take your old blades into any good dealer/tractor supply and they should be able to get you what you need. Might even find them at a farm supply store if your bh is a common brand.

either installed upside down or maybe universal blades that are not compatible with your mower,I have b ought universal blades that had different bends in them with did not cut very well,I always just bite the wrench and buy OEM blades now,I replace mine every season instead of sharpening
