The Power Behind the John Deere Z994R Zero Turn Mower

John Deere Z994R Zero Turn Review - John Deere Z994R

The Engine

The Z994R packs plenty of punch and power through the use of its three-cylinder diesel-powered engine that boasts 24.7 horsepower. It has a rated power at 3200 rpm which meets the emission standards set forth by the U.S. Environmental Protection Agency (EPA) since it has a low-emission diesel engine that is designed for the best performance possible, even when used under less than desirable conditions. Its high-torque engine puts off low levels of noise which is also a huge plus, especially for the neighboring houses or businesses. It also gets great fuel economy which will save you money in the long run.

The liquid-cooled design of this diesel-powered motor allows for better-operating temperatures that stay more consistent than ones that are cooled by air. A good cooling system, along with a full-pressure lubrication system, allows for a longer life of the mower. The power of the John Deere Z994R Zero Turn Mower has been compared to the others in the line-up as the heaviest to haul but the most powerful and efficient.

The Transmission

When it comes to the drive system of the John Deere Z994R Zero Turn Mower, two 13-cc unitized hydraulic pumps keep this machine running at top speed. It has commercial-grade wheel motors that are located within a single unit. The design of having one pump with a motor drive for each wheel allows for much better cooling which makes it easier to check the hydraulic oil and refill it when necessary.

Features and Comfort of the Mower

There are four different deck sizes that are great whether you are mowing, trimming, or grooming and one of them has a mulch on-demand option that is easy to use. You can also opt for a side discharge mower deck or a rear one which is great for keeping grass off driveways and sidewalks.

You can choose from three different seating options for this mower and each one includes the ComfortGlide suspension as well as adjustable armrests and an amazingly thick cushion, all of which will keep you comfortable throughout an entire day of mowing.

Durability

This mower was built to last and even comes with a three-year or 1,500-hour warranty. Wear and tear on the engine is reduced by the top-of-the-line lubrication system and the oil filter will keep the engine running clean for years to come.

Pros and Cons

Customers enjoy this mower because of the power at pax and how quickly it gets the job done. The footrests are not as comfortable as they could be, but the seating options are wonderful. It has a sleek and efficient design, but it is heavy to haul from one location to another.

Overall, this mower is like the granddaddy of the John Deere R Series. It is easy to operate, comfortable to ride on, and comes with plenty of options to fit a variety of needs and preferences.
