Can I use the DEWALT bar on the Scotts saw?

No. The DEWALT DWZCSB8 is made for the DCPS620 20V MAX pole saw. The Scotts PS45010S uses its own 10-inch Oregon bar and chain.

Which is better for a homeowner with no pole saw yet?

The Scotts saw, since the DEWALT part is only a bar. Budget for the durability complaints: several reviewers had gears or the motor fail after short use.

Is the Scotts saw worth $84.19 over a $19.99 bar?

They solve different problems. The bar restores an existing DEWALT tool for $19.99 at Beaver Industrial Supply as of November 3, 2026. The Scotts saw is a full tool at $84.19 at Amazon as of November 3, 2026.

The DEWALT bar has no motor or gears to fail and is reversible for even wear. The Scotts saw's weak point is its internal gears and motor, per reviewer reports.

Does the Scotts saw need an outlet?

Yes. It is an 8-amp corded saw, so you need an extension cord long enough to reach the tree.

How high can each reach?

The Scotts pole is 9 ft. 5 in. long. The DEWALT bar's reach depends on the DCPS620 pole it is mounted on.
