No, they are ready to use right out of the packaging. Just be sure to install them With the cutting edge facing the right way.
Yes it looks like the same one I got.
Due to the many types of lawn tractors it is difficult to answer with a simple yes or no. First it appears safe to assume your Poulan is running a 42 inch mower deck. So what we need to know about your Poulan is the style of mount is used for the blades at the deck hubs. Most mowers use a 5 point star at the center where the bolt goes through the blade and into the deck hubs. If your model uses this design, these blades will likely work. However, a few models use a different size star and yet others use an oval (more common on John Deere tractors). If that star is the same on your Poulan, these blades will work. But it is still highly recommended you take an old blade to your local store and match them. Since the differences from model to model are very noticeable, it's easy to visually match the star. Other differences in blade design are the twists and bends. These are not a problem between brands as they will vary according to mulching capability and do not affect the performance of the machine.
This would be a better question for Home Depot staff
Probably yes. Note the 6 sided star at the center of the blades where they bolt to the deck hubs. If that star matches yours, they should fit. However, it is always best to take an old blade to your store to match them.
Hello Andrew. There are many brands of lawn tractors that use a handful of blade styles. Add to that, in many cases different brands are made by the same companies but have a different name. This makes it very difficult to know if a specific blade will fit your brand. One way to help know is to observe the blade in the photo. It has a star pattern in the center hole where the bolt goes through to attach it to the deck hub. If that star pattern matches your mower it will likely fit your mower. But because there a few mowers that use a different size star, the best way to know for sure is to bring an old blade to your local store for a positive match.
Yes they will fit all mowers of 42 inch mower decks that have a star pattern in the middle where's the bolt goes
That I do not know offhand I would have to look at the blades that are on there if they have the star pattern in the middle the most likely they will fit
I looked up blades for your John Deere 42 inch. They do appear to be the same. I'm always concerned if the blades have a 6 sided star pattern where the bolt passes through. According to John Deere, yours have a 6 sided star. But to be safe I always recommend bringing an old blade to your store for a positive match since sometimes that star may be a slightly different size. Having the proper size ensures a good fit to the deck hub keeping the blades secure and balanced.
These should fit your Cub Cadet. Because many brands of tractors are made by a single company there's no a lot of variation in many of the parts. However, blades can vary in how they mount to your tractor. Note the blades center hole is a 6 point star. This star pattern helps keep the blade centered and fits into a depression on the hubs where the blades bolt to the deck underside. But that star isn't always the same size and some brands use a different pattern instead of a star. I looked up blades for a Cub and have posted the picture. While they look the same, it's always best to take an old blade to your store to make a positive match.
