The best part about the TORO Z-Master 4000 Mower is the options you have to choose from. You can add or remove certain aspects depending on your mowing needs. The Kawasaki high-powered engine ranges from 24.5 HP to 31 HP. You can pick your model to maximize top speeds of up to 12 miles per hour or get a blade speed as high as 18,500 FPM.

Commercial zero-turn lawn mowers generally have cutting speeds between 7 and 13 miles per hour. So at 12 miles per hour, the Toro Z gives you a relatively higher speed than competing models. Another equally impressive aspect is the fact that increasing ground speeds do not impact its cut quality. 


This mower is packed with some great features. Below are some of the most notable features.

  • Strong Kawasaki FX Engines
  • Large Voodoo Trac drive tires
  • LED headlights
  • Turbo Force cutting deck
  • Suspension seat or MyRIDE suspension platform

Cut Quality

The Toro Z-Master 4000 series comes with the trusted Turbo Force deck. This deck has been around a while and is known for high cut quality. Not a lot has changed in terms of the deck on this mower compared to previous models.

The spindles and everything are the same as in the past. The deck does have dual capture anti-scalp wheels. These are housed in a way that makes it difficult to damage the wheels.

The deck features a deep design that is a little different than most other commercial mowing decks on the market. This makes the deck very good at mulching grass.

Overall, the Toro 4000 series provides a great quality of cut that is sure to make your lawns look great.

The Toro 4000 series is a mower that has been around a long time. It has a pretty good track record of lasting a long time. The new, updated models of this mower will probably show similar durability. This is a commercial zero turn that is built very well.


With large lawns or back-to-back projects, having a model that doesn’t make the mowing physically arduous is a huge plus. As part of its comfort-centered design, the TORO Z-Master 4000 Mower has a comfortable suspension seat with complete lumbus support, so you get quality back support. 

Poorly designed lawn mowers will affect your posture and cause serious health problems in the long run. But, the TORO Z-Master 4000 Mower takes this concept one step further with the company’s unique MyRide suspension system. 

Using this modern technology, you can shift and adjust the seat to fit your size and weight. Custom adjustments may come with an extra cost but have a huge payoff. Rear shock pressure suspension is easily adjustable up to 3.6 inches.


When it comes to commercial mower designs, you want a model that takes the user into account. The Torro Z provides features like a deck step plate to wipe the mud off your shoes and a step-through front end, which makes climbing onto and off of the model extremely easy. 

Additionally, the mower has extra features like a phone holder, time counter, USB ports, and a drink holder, all within arm’s length from the cushioned seat. So, this is the perfect model for larger jobs that require long hours. You can keep your phone charged and stay hydrated while mowing. 

These points may not sound important to the average reader, but they make a huge difference when you’re a professional landscaper and need to remove debris from the middle of the yard.

The manufacturing company incorporated several key features to make this model long-lasting. One such feature is the rubber discharge chute, which deflects and controls the discharge in a way that doesn’t cause damage to your machine or surrounding environment.


There are two types of warranties you can get for your mower. The limited warranty is for 5 years, covering 1,500 hours (two years without an hourly count.) These types of warranties are common in commercial zero-turn mowers.  

Why You Should Trust The TORO Z-Master 4000 Mower 

The Toro Z Master’s features aren’t just for show. Its turbo force deck actually uses military-grade 80 KSI steel, which takes high-strength to another level. Furthermore, the company has put this model through several stages of extreme testing to make sure it’s of great quality.

Specifically, 100 million hours of testing in different climates on various terrains and grass types prove its efficiency and the brand’s commitment to quality products. Technical features like the tubular frame and I-beam also add to the model’s overall appeal. 

Finally, the comfort-focused features like the MyRide Suspension System, padded seating, deck step plate, and well-placed USB ports and drink holders help make the day-in and day-out usage easier. When you have a company dedicated to creating top-of-the-line products that place user comfort as a design priority, you are bound to get a great machine.
