2012 Husqvarna 54 in 25 hp MZ5424S Zero-Turn Review

Executive Summary: Consumer Reports, myself and anyone who ever tried to mow a side-hill with a residential zero-turn will tell you to stay as far away from them as you can get. This is not a residential zero-turn.   This is an estate level (Husqvarna calls it a Landowner) mower with a commercial, heavy-duty frame and transmissions. It has the same great deck found on the GT6000 Craftsman garden tractor. If you have 2 to 6 acres to mow every week seriously look at this zero-turn before buying anything else.  I’m going to put this mower in the same class as the new Craftsman Premium Tractors for comfort, ease of use and ruggedness.

This zero-turn will mow 2 to 2.5 acres an hour under just about all conditions.

Deck cuts great but mulches average.

My Review:

This is a “hybrid” zero-turn.  It has a really strong, commercial frame, huge tires, good motor, and transmission with a good residential deck.  This zero-turn will handle slopes better than all of the residential zero-turns. I really, really liked the larger MZ6128ZT but it was too big and expensive for most homeowners.  This zero-turn takes all the best features of that mower and gives you a smaller deck at a reasonable price.

The Zero-turn: This is the same frame found in the MZ6128ZT.  The frame is stronger than all of the other residential zero-turns and has a great history.  Owners love the ease of starting, simple deck height adjustment, easy fine tuning of tracking and control levers, and excellent routine maintenance accessibility. This machine is built like a tank and will cut your mowing time in half over using a garden tractor.  The ZT 3100 Hydro-Gear transmissions are stronger than the other transmissions on the other brands of residential zero-turns. These hydros are much stronger than the ones found in the Z245, Z425, Z445, Z465 John Deere.

Z245 – HydroGear EZT transmissions – Residential
Z425, Z445, Z465 John Deere – ZT2800 transmissions – Medium duty residential
MZ5424S – ZT3100 transmissions – Heavy duty residential, light duty commercial –
MZ6128ZT, MZ5225ZT – ZT3400 transmissions – Commercial use including municipalities and entry level landscapers.

The Engine: The 25 hp Courage Pro has proven itself to be a dependable and high-torque engine.

The Deck: Commercial Cutters feel you need a “fabricated” deck.  Do You? Probably not.  Why? A fabricated deck is reinforced at specific points to take the beating of loading the zero-turn on and off a trailer many times a day.  It is also reinforced so the operators can bang into foundations, lamp post and other obstacles 40 hours or more every week.

This deck is a “stamped” deck similar to the decks on the John Deere zero-turn mowers.  It is designed to mow well and it will give you many years of use around your acreage.  This is the same deck used on the 8 mph Craftsman GT6000 Garden Tractor.  Husqvarna has increased the blade tip speed so it will mow well at 6 to 7 mph.  You are going to get your lawn mowed faster than you ever thought you could with this mower.

This deck does side-discharge mowing as good as any other brand.  It bags ok with the standard residential bagging system. The stamped deck gives you better airflow than a fabricated deck and this allows the addition of a bagger without the cost of a power driven blower. This reduces the cost for clippings and leaf removal tremendously for the noncommercial customer. It does not mulch as well as a 42 or 46 inch deck. Why? This deck is a “vented” deck.  A lot of air is pulled in through the vented spindles and allows the grass to stand up and get cut evenly.  All this air makes for a great cut, but when you block the side discharge (use a mulch plug) that air has to go somewhere and it does.  It goes out the right front corner of the deck. If you are mulching dry grass on a windy day or leaves in the fall expect to be covered in debris.  I don’t consider this a problem, but be aware to get the best cut when side discharge mowing there is always a trade-off when mulching.

This zero-turn will mow in reverse.  You can also pull the same attachments as your lawn tractor.

 People who buy this zero-turn know what they are buying and this is just what they want. There are no reviews available yet, but I know the owners will love this mower.

I’m not going to go into a lot of detail on this review.  If you have specific questions leave a comment below and myself or the readers will be glad to answer them.  This is a great tractor and if you want one to last this should be at the top of your list.

Comfort – Ease of Use:  Deluxe high-back seat, easy to use operator controls, good field of view.  This zero-turn is easy to drive.  The steering levers are easy to adjust and all the controls are right at your fingertips.

Power For Mowing:  This tractor has plenty of power for side discharge mowing every week.  It also has plenty of power for mulching and bagging.

Reliability – New to 3 yrs: There are no reviews available yet, but I know you will love this mower. This mower is serviced by Sears.  One thing to know – Sears takes the mower out of the shipping crate but they do not “setup” the tractor. (John Deere dealers are the only retailer who does) You have to put gas in it, and run it for the first time. If there is an assembly problem you call 1-800-469-4663 and a service tech comes out to your home and fixes the issue. The store where you picked it up from or the delivery team does not repair the tractor. If you buy another brand make sure you understand the repair policy if you have a problem.  Many of the other brands make you take the mower to an “authorized service center” for adjustments and repairs.

Handling – Traction/Steering:  This mower has good traction for a zero-turn and has better traction than any of the residential zero-turns (Under $4000) It will handle moderate slopes well and excel on flat, uneven and rough terrain.  I recommend you never use a mower like this on wet or drought-dry slopes.

Mow – Mulch- Bag:  This deck gets high marks by owners for mowing. Husqvarna increased the blade speed on this mower so it will mow faster than you are used to with your lawn tractor. I expect it to mow well at 5 to 6 mph.  With this mower/deck you set the height of cut using a lever on the right side of the frame.  You can preset the height.
