Rated 4.4 out of 5 by 14 reviewers.
Rated 5.0 out of 5.0 by Great Lawn Tractor What a world of difference from my 18 year old Simplicity Lawn Tractor This tractor is so much quieter, smoother riding, and more comfortable. Nice clean cut and easy to maneuver. Controls are logical and and easy to use, the reverse safety button takes a little practice to use, but not a big issue. Overall very satisfied, especially after purchasing online the price was reduced and Home Depot honored their 30 day price guarantee and refunded the $200 price difference. May 10, 2016
Rated 5.0 out of 5.0 by All Good with D125! Just got my new mower delivered from a John Deere dealership. Fantastic and informational talk with the driver. Very knowledgeable. I mowed my lawn in record time, fabulous cutting and comfortable seat. Lots of power when needed, slow easy maneuvering when needed also. Easy clean up with the hose after. Can't beat the price with a stick. Thank you , John Deere, and the people at L.F. Trottier & Sons in White River Jct, VT. June 22, 2015
Rated 2.0 out of 5.0 by it has pretty paint I've just bought this lawn tractor and used twice and I've noticed that the blade adjustment gets in the way getting off the mower it cut's all right I've also bought a bager to go with it and I'm dissatisfied with the grass clippings that's left behind my craftsman mower does a better job and its 15 years old I'm not sure if I made the right choice in my selection of mowers the John deer is pretty but that doesn't mamakek it cut any better time will tell like I said I just have used it two times so time will tell on it May 17, 2015
Rated 5.0 out of 5.0 by very good mower I purchased the mower a month ago. I really like the mower except for two things. The attachment lift lever position makes it hard to mount and dismount mower. The reverse foot pedal is too narrow. My foot slips off of it very easily. June 26, 2015
Rated 5.0 out of 5.0 by Great Mower Love the high back seat on this mower. the mower has the right amount of power for its size. it handles a lot better then the last two riding mowers I have had, I would recommend this mower to anyone. I bought this mower from a john deere dealership. I would recommend going through a dealership since buying from box stores does not always assemble their products correctly. I have talked to technicians from landscaping dealerships, they said they are always correcting the mistakes from box stores. May 4, 2014
Rated 5.0 out of 5.0 by Value, Quality, Style Looks great. Nice smooth engine. Tight turns. And I don't have to mow anymore. My girlfriend does it now :) What's that tell 'ya? All I have to do now is weedeat! I love this mower. August 16, 2014
Rated 4.0 out of 5.0 by Excellent lawn mower, just purchased, Had a John Deer L110 for 14 years. All features are great. The high seat back is very nice and comfy! Nice and smooth running and cutting. I do not like the gas filler tube. Exiting the mower to the left when height adjustment is 3 or bow is difficult. Besides that it is a very nice machine! August 16, 2014
Rated 5.0 out of 5.0 by Great Machine This is my first riding lawnmower because it was too much for me to cut the hills. I almost bought at the end of last season but decided to wait. I am so glad I did. The D125 has plenty of power and it manuvers easily. The rear bagger works very well with the high lift blades and the thatcherator work so well that I do not need to hire anyone. The engine runs smooth and is fairly quite. June 9, 2014
