21 in. Classic Kohler XT8 Push Gas Walk-Behind Lawn Mower is rated 3.8 out of 5 by 93.
Rated 5 out of 5 by from 26 Years Later and It Still Works Perfect! Model 911037 Serial No. 00135 Starts most always on the first pull. Very good side disperse. Very comfortable handle position. Owning it for over 26 years and the only maintenance I have done is change the oil and sharpen the blade. I mow a 1-2 times a week from April - October.

Rated 4 out of 5 by from Very nice mower. I like the Ariens mower for several reasons. 1) the bagging is unbeatable, even in the rain, it will completely pack the catcher full - no clogs. 2) Starts every time the first time. 3) The Kohler motor, even though it is small in cubic inches, it has plenty of horsepower to handle tall grass and blow through it.

Rated 4 out of 5 by from This is - overall a great product - Purchased the Kawasaki LM-21-SW a year ago - and I would recommend this mower. But I do have a couple of modification I wish Ariens would consider. If you have hills or any sloping terrain I would not recommend the swivel wheels. The unit wants to move in the direction of the slope. It would be nice if the swivel wheel lock mechanism would lock both wheels. One locked wheel is basically useless. I also need to load this machine onto a pickup and pushing it up a ramp is very tricky because of the swivel wheels. Another issue is the pins that holds the front swivel wheels has fallen out a number of times. I have had to replace both pins (lost them in the grass) because the clasp that hold the pins falls out. I replaced both swivel wheel pins with new ones and replaced the clasp with a coder-pins. Now if I need to adjust my wheel height I have to replace the coder-pin. Makes it harder to adjust the height but now I am not at risk of losing the SW-Pin. Changing the oil is next to imposable without making a mess. The drainage plug is set into the side of the engine disabling the ability to catch the oil when the drainage plug is removed. It would be nice if the unit came with some type of extension tube enabling the owner to change the oil without making a mess. I made an extension tube that I use enabling me to drain the oil out beyond the mower deck. Changing the oil a couple of times got me to think about this modification that should have been part of the design to begin with. Like I said, I would recommend this unit. Over all it's a great machine. All of the above issues I have been able to work around making it a real nice unit.

Rated 4 out of 5 by from Ariens model LM21 a good product after 6 years I purchased an Ariens LM21 with the swivel front wheel option 6 years ago. It has the 6.5hp Briggs & Stratton Quantum engine. It starts after priming it 7 times and one or two pulls time after time and year after year. The only time it does not start well is if you turn it off to take a break and try to re-crank while its hot. It may take 5 or six pulls to fire it up again. The only part thats broken is the left rear tire tread skin ahs torn apart due to rubbing against bed pavers etc. Just ordered anew one. This has been a very powerful and good mower. The most powerful I've owned, better than the Snapper I had. I would purchase another when this one goes out. Good mower.

Rated 3 out of 5 by from Good sturdy mower, but... Good machine, mows well, always starts (B&S engine). Found it didn't always shift the cuttings into the bag - especially if grass damp (wet summers here in UK) - had dealer weld wings onto blade to increase lift (the same as he did with a mate's Ariens) - no more problems lifting cuttings. This should have been standard for UK - the dealer knew exactly what I was wanting and how to achieve it. Very disapointed with the drive - fine on level lawn but now mine isn't level (recently moved) - it's on an incline. Drive slips and is unreliable. I've had new drive bits (the rubber tyred wheel, etc..) and had the spring checked and tightened, but no better. Am now looking for a good mower with a direct drive with no possibility of slipping.

Rated 5 out of 5 by from excellent mower inherited an Ariens mower 15 years ago. It started on one pull over its lifetime. Just updated and hope to enjoy the same quality. The replacement started on one pull out-of-the-box....a good start! Extremely simple to operate. Made well. Runs well. Solid.

Rated 4 out of 5 by from Would buy another when this one goes. Started the first pull and worked fine for my small backyard. Second time was a problem until I cleaned out aluminum metal shavings out of the fuel bowl. Not a problem since. Really vacuums up the grass, leaves etc..
