Mowing run time will vary greatly depending on the height of grass, the thickness of grass, and the type of grass. One of the big differences with the mowers is how many battery packs each one uses, and how those packs are combined/utilized to power the mower. While this head to head is not a scientific research project, we did take measurements, evaluate each mower in several categories, and rank them dewalt tools against each other. When we begin to pull together our Head-To-Head tool tests, we always try to figure out how to make the tests consistent, repeatable, and fair. Often, we figure out how to take the human variable out of a test, but we couldn’t do that with mowers. For tune-ups, breakdowns, and everything in between, a mechanics tool set on hand might just save your cars while saving your money.
I had already done like two buckets of mud without any incident but on this last mix, the drill gave up the ghost, complete with smoke and that nasty burning electrical smell that is never good.

Watt-Hours is calculated by multiplying the voltage by the battery pack Amp-Hours. This calculation allows us to compare the total energy available to do the work based on both the voltage and size of the battery pack (amp-hours). In order to get a relative comparison of run time, we tested the mowers in a very large field under load conditions.
We did a basic decibel test to measure the noise of the mowers in a controlled situation to get a relative comparison of noise. The test consisted of running each mower with the deck raised to its midpoint level sitting on a concrete slab. We placed each mower in the exact same designated spot on the floor in a large barn and the decibel meter located in the same height and relative position to the test mower. After cutting the grass we evaluated how well the grass was cut.
I gave them a call, and they explained to me the whole scenario. The Factory Owned DeWalt Service Centers use the Guaranteed Repair Cost Program. They promise the price of a repair will not exceed the published replacement price for dewalt Hand tools that tool. What that means is if you send in your drill because it has a broken switch, they only fix the switch and charge you for that plus the shipping back to you. The repair cost is NEVER more than a set amount for that tool.
