Husqvarna MZ6128ZT 28 hp 61 inch Zero Turn Lawn Mower Review

This mower was a little too big for Sears customers so they replaced it with a 54 inch version: Go here to read my review: Husqvarna 54 in 25 hp MZ5424S Zero-Turn Review

Every once in a while a mower manufacture will “get it right”   Here is a great example.  Husqvarna has developed a good, solid, zero-turn capable of high-speed mowing and still keeping the price within reach of the average homeowner

A commercial mower at a homeowner price!

If you mow 3 or more acres and want to get it done quickly this is the mower for you.

If you want your lawn to look as good as your neighbor’s who has a “professional” mow hers, this is the mower for you.

If you want a good “commercial grade” mower that will last you twice as long as the other zero-turns you looked at, this is the mower for you.

If you are just starting your lawn business and you have no more than 25 hours a week of mowing to do, this is a great starter zero-turn.

I call this mower a “semi-professional” zero-turn.  Others call it a high-end residential.  It works well for a small commercial mower and a homeowner who wants a machine that will last.

Large tires, wide stance.  The larger than usual tires and wide stance will make this a great zero-turn mower for slopes. It will mow your septic mound with ease.  The anti-scalp wheels on the corners and nose wheel will keep the deck from digging in on the rough parts of your yard.  If you have light or sandy soil the larger tires will keep the machine from “divoting” your lawn and tearing up the turf like the residential zero-turns tend to do.

Welded steel deck.  The deck is heavy enough to let your teenager use the mower and you will not have to worry about them tearing it up.  The deck will quickly get rid of the grass.

Speed.  This mower will mow at up to 8 MPH!  If you are currently using a 54 inch garden tractor to mow, this zero-turn will cut you mowing time in half!  This machine is capable of mowing up to 4 acres an hour.  Compare this to 1 1/2 acres an hour for a 54 inch residential zero-turn or garden tractor.

Price. At about $5000 on sale this mower is one of the best values on the market.  For that amount you get a strong, dependable, machine capable of mowing as quickly as zero-turns costing 3 to 5 thousand dollars more.

Warranty:  I normally don’t discuss warranties because the normal manufacture warranties are all the same. (They only cover defects and do not cover engine or trans.  Yes, read the fine print on your MTD warranty) but the warranty and options available through Sears needs to be covered on this mower. The standard 3 year Husqvarna warranty only covers the mower.  It DOES NOT cover the engine and transmissions. If you have engine problems or transmission problems YOU have to contact them and get the repairs made.  I have also found that servicing dealers typically do not cover labor for the repairs, transporting the unit to their shop, and other items they may find wrong while your mower is in the shop.

Sears offer a 5 YEAR Protection Plan on this mower.  The protection plan is set up that a Sears tech comes to your home, diagnose and repairs the mower without any additional cost to you.  The plan not only covers the standard warranty parts, but in this case covers the engine, transmissions and wear and tear.  In other words if you wear out the belts, burn up a transmission, or literally run the wheels off this machine, it’s covered.  About the only items it doesn’t cover are blades, tune-ups, physical abuse, and cut tires.

Cons: From a commercial stand point I would limit this mower to about 25 hours a week.  If you are running your machines more than that I suggest you move up to a iZ or PZ unit.  But if you do a lot of residential this machine is light enough to work well on those lawns.

The ZT 3400 drives are strong enough to handle all residential and most commercial mowing.  You can use it with most pull-behind attachments like  a yard cart, dethatcher, or sprayer, but if you are planning on mowing slopes for hours at a time or pulling an Acrease Wing Mower I suggest that you go with a unit that uses cast iron drives.  If you have a lot of hills to mow go with a Toro Grandstand or ExMark Vantage.
