Garbage!!! Made of cheep parts. The manufacturer will never admit the obvious and honer warranty on anything. According to them everything is abuse. After one season rubber tire falling apart. Drive wheel gear shield that is as thin as a plastic cup cracks. I'm a 60 year old man cutting flat even lawn at home.

Ariens proves they know how to make lawn machines
I purchased the Ariens to replace my Snapper ninja commercial walk behind. The Ariens is lighter, easier to start, mulches as well as the ninja but has a bag in case you want to collect. The handle adjustment is superior to the Snapper as is the speed control. All in all a better value considering the Ariens was $379 at Tyler tool while the Briggs powered Snapper was over $700 at Power Equipment direct. The Snapper was a commercial grade machine however while the Ariens is not rated that way.

I bought this model Ariens 3 years ago. It does do a nice job of cutting the lawn either with the grass catcher or without. With the grass catcher it picks up more clippings that my Craftsman did and it's much easy to disconnect the bag for emptying. Without the grass catcher it does a great job of mulching the clippings with very little leftover grass clipping. The height adjustment is notorious for changing heights on its own when you are mowing uneven surfaces.The electric start is useless. The starter doesn't have enough torque to start the mower cold and starts the mower when warm intermittently. The male end for the charger on the mower is difficult to disconnect when you want to use the mower. The oil drain plug is in a nice easy spot for changing the oil but there is no where for the oil to go, so I drilled a hole in the housing right under the oil brain plug so now changing the oil is much easier and not so messy. The 2 reasons why I bought this model Ariens was because of the one touch height adjustment and the electric start. Unfortunately neither work very well.

Does it have a blade brake clutch or doesn't it? One review site (TopTenReviews; which gives it its Gold #1 out of 10 award) says it does; another (Consumer Reports) says it doesn't. I want that feature, if it lets you stop the blade without also shutting off the engine.

Tell me the truth!

BEST ANSWER: No, this mower does not have a blade brake clutch
What would be the shipping cost for delivery to 4020 Middleton Loop, Dumfries, VA 22025?
Are there any other costs associated with this purchase?
Henry on Apr 22, 2015
BEST ANSWER: Standard freight to your zip code would be $79.79. If you were to need a lift gate to have the item lowered tot he ground from the truck the cost would be $138.79. CPO does not charge tax to VA so there would be no other cost.
What is the shipping cost?
Henry on Apr 22, 2015
BEST ANSWER: Please provide a shipping destination state and zip code and we will be able to calculate a freight cost.
Is the wheel height (cutting height) a single lever or by individual setting, front/back??
Senior Citizen Lawn Mower on Feb 21, 2015
BEST ANSWER: This unit can raise or lower the deck to any of 7 cutting positions with one lever.
