  14 Questions
Q: Where can I purchase arm rests for a 42" Ariens mower?
by TJ Davis from Florida on April 06, 2014

A: T.J. - unfortunately, the stock seat that comes on an Ariens Zoom42 mower is not compatible with an arm rest kit. If you really want arm rests on your Zoom42, you'll need to purchase an a new seat that has arm rests.
by Jose, Product Expert
Q: For the Ariens 42" zero turn, how many anti-scalp wheels on the front of the deck and how many on the rear of the deck?

by Joe from Virginia on August 24, 2013

A: This particular model is going to only have 4 anti-scalp wheels, you will have two in the front and two in the back. The picture from Ariens is deceiving because it is a picture of a Zoom 42", but they do not add the right anti-scalp wheel on the front for whatever reason.
by Jose, Product Expert
Q: What is the stability of this mower going up and down hills?
by Jack Voelz from Indiana on April 12, 2013

A: Jack - the Ariens Zoom 34 will mow effectively on slopes or inclines up to 17 degree's of slope. Any steeper than that and you may have traction issues, especially if the grass is wet.
by Jose, Product Expert
Q: The Ariens 42 says that it's 54 inches wide is that with the grass deflector and does that fold up to make it less. Thanks
by Sam Panasci from New York on February 20, 2012

A: Sam - yes, the overall width of 54" is with the side discharge chute cover in the down position. If you fold it up, the overall width of the mower is approx. 43-1/2".
by Jose, Product Expert
Q: What is the difference between Transaxles and hydorstatic transmition on the ZTR mowers?
by CK on July 24, 2011

A: Thanks for your inquiry.

The difference between transaxle and hydrostatic transmissions on zero turn mowers is as follows:

The transaxle has the pump and wheel motor in one case. It is belt driven.
The hydrostatic is propelled with fluid and a seperate pump. It is not belt driven.
by Jose, Product Expert
Q: Todd, if i buy this mower and something goes wrong within the 3 year warranty, how would i get it fixed?
by Joe from Connecticut on June 26, 2011

A: Joe - any needed warranty service would be provided by your local Ariens dealer. We have a link on our web site under customer service that would allow you to look up the closest Ariens service centers using your zip code.
by Jose, Product Expert
Q: I have a new 2011 Ariens Zoom 42 mower and would like to purchase a sun shade for it, but all that I have found are for 2008 or earlier model years. Is there a sun shade available for the new model?
by Gary from Ohio on June 24, 2011

A: Gary - Ariens stopped offering a sun shade for their Zoom series zero turn mowers a couple of years ago. There are a couple of after market sun shades out there that will fit on the newer Ariens Zoom models, but we do not offer one.
by Jose, Product Expert
Q: Are zero turn mowers set up to pull say a 17' dump cart for other yard work like conventional riding mowers?
by Joe from Pennsylvania on June 23, 2011

A: Joe - the maximum weight that a zero turn mower can "pull" (tow) is typically about 200 - 250 pounds. You could pull a 17 foot dump cart, which weighs about 160 lbs. You just couldn't put a whole lot of "stuff" in the cart.
by Jose, Product Expert
Q: the ariens zero turn mowers, do they have snow blowers available? and if so are they easy to mount? just trying to cut back on the number of gas engines to maintain. thanks Troy
by Troy Donth from Minnesota on June 11, 2011

A: Troy - Ariens does make a snow blower attachment that mounts to the front of their zero turn mowers. I would say the installation is moderate in terms of ease. We don't stock the snow blower attachment, but we would be able to special order it for you if you decide you want one. To be honest, the snow blower attachment is not a big seller, mostly because of the handling and traction of a zero turn mower on snow and ice. Give us a call if you want to find out more about the Ariens snow blower attachment for their zero turn mowers.
by Jose, Product Expert
Q: I've looked at this at home depot and at your competitors wise guys web site and they both have briggs and stratton as the engine your web site says a kohler why is it a different engine for the same mower?
by Christi from Texas on May 22, 2011

A: Christi - I can't comment on what our competitor's are showing on their web sites, but if you are looking at a 2011 Ariens Zoom 42 (#915159), the engine on this mower is definitely a 22hp Kohler Courage engine. The 2010 model (#915141) had a 16.5hp Briggs and Stratton engine, but this model is out of production and no longer available.
by Jose, Product Expert
Q: I have a 42" front engine tractor currently. I want to cut down mowing time on a 2/3 acre lot. Would a 42" zero turn be recommended? Would 48"+ be overkill?
Thanks!

by Tim L. from Wisconsin on May 17, 2011

A: Tim - for a lot that is less than 1 acre, you could probably get away with using a 32" or 34" zero turn mower and still cut your mowing time. A 42" model would be plenty big enough. Yes, a 48" model would be more mower than you need for mowing less than one acre.
by Jose, Product Expert
Q: Does this Ariens Zoom42 (42") 22HP Zero Turn Lawn Mower (2011 Model) really come with a two-cylinder Kohler engine?
Thank you!

by Alan Church from South Dakota on May 16, 2011

A: Alan - yes, the Ariens Zoom 42 features a Kohler Courage twin cylinder engine.
by Jose, Product Expert
Q: Describe how much assembly is required when this mower is shipped to me?
by Bill Moyer from Kansas on April 21, 2011

A: Thanks for your inquiry. The only assembly required is putting on the seat. Then you just have to gas , oil and go!!
by Jose, Product Expert
Q: Todd, what is the overall length and width of the 42" machine?
by Hollis Earnest from Illinois on March 24, 2011

A: Thanks for your inquiry. The overall length of this model is 64 inches. The overall width of this model is 54 inches.

Love The Mower Hate The Mulch Kit
I purchased an Ariens Zoom 42 from a big box store and the mulch kit from mowers direct. After installing the mulch kit (which requires jacking up the mower and removing the blades - a real pain BTW), I experienced a trail of grass about 2 inches wide trailing from the mower, especially when mowing in a circle (i.e., around trees) . When shopping for the mulch kit, Ariens told me the kit needed an additional part (51522800) which basically are foam block inserts to block the grass leaking... more

Overall, I'm Satisfied
I spent a couple of weeks searching for a 42" mower for my acre and half yard. Decided on this Ariens over the Toro time cutter SS.

The Toro looks very cheap to me. I paid by check, it took longer, but I saved 50 or so bucks. Get the lift gate service- you can't unload the mower without it. The mower came in an 18-wheeler, packaged well on 2 pallets. It was very hard to get off the pallets. I got aggravated and lifted mower off pallets completely after busting up my thumb trying to... more

Major Problem
This is a nice mower but it has one major problem. If you sit in one spot for more than 5 seconds, the exhaust and heat from the muffler burn the grass. It takes a couple of days for the grass to turn brown and then you can see the outline of the muffler and where the exhaust discharged. This mower definitely needs a heat shield around the muffler.
Pros: Easy To Use
Cons: Needs A Muffler Heat Shield

Very Good Machine, Cuts Very Well And Easy.
The truck dropped it off at 9:30 AM, at 10:20 I started it and took my first ride. Some advise, don't try to take the crate apart. Get a recip. saw and cut the crate off in pieces, pull both bypass levers out and lock in place, then push the machine off the pallet by hand. Piece of cake.
Pros: Durable, Easy To Use, Features, Price

Tired Of Taking So Long
I had a grate deal of objects in the yard. I mow my mother in laws yard also, she is 80 and doesn't want to give up any bird baths or bird houses. She has plenty and this mower has helped get around all of these objects a lot faster. Cut 45 minutes in mowing time.

Great Looking Machine
I have been trying to get use to stick steering and am not very good yet, but once I catch on, I'm certain that I will really enjoy it. It is well built and a great looking mower. I really had a time getting it uncrated. A sawsall and two friends finally got the job done.

This mower was just delivered to me today and I spent most of the afternoon mowing my property. I am quite satisfied so far, but the mower I received is different from the one pictured. The steering bars are different and the front plate is orange, no big deal, but deceiving. I also ordered the headlight accessory and tried to wire it up, but couldn't find the wiring harness mentioned in the instructions and the picture of the front of the mower differed from mine. I also could not find any... more
