John Deere Branded Engine

As you will probably have noticed in our extensive John Deere riding mower reviews that the D125 John Deere lawn tractor has a John Deere branded engine.

John Deere D125 Riding MowerHowever this doesn’t mean the every engine comes from the same manufacturer.

John Deere D125 models have engines that include:

  1. Briggs and Stratton:
    The twin-cylinder engines of this model generates the power needed to ride this mower and handle several landscapes. This enhances its ability to start consistently and cut the grass on a lawn perfectly. It is designed to last long while delivering high performance on a consistent basis.
  2. Kawasaki:
    This Kawasaki engine is considered by many people to be long-lasting and well-suited for towing or pushing. Its twin-cylinder engines come highly recommended because of its heavy-duty transmissions. They are also strong and reliable.
  3. Kohler:
    This model of engine is designed to be reliable and powerful enough to ensure that a D125 tractor handles any landscape. It offers quality, an electronic fuel injection, and a Kohler direct injection. The engine is designed to be reliable for lawn mowers.

Each of these engine models comes with a John Deere D125 manual which provides instructions on how personal injuries or damages can be prevented.

However, in most cases the engine will be John Deere branded.

As each engine is more than capable of providing the necessary power to run this mower at top performance levels it really makes no difference which manufacturer provided it; after all John Deere would not allow their brand name to be used on an inferior product.

So let’s take a closer look at exactly what this engine offers.

20 Horse Power

The D125 has a John Deere branded 20 HP engineOne of the best features of the D125 lawn tractor’s powerful V-twin engine is its full-pressure lubrication.

The 20 horsepower which it is able to generate offers the lawn tractor the power which it needs for side discharging, bagging, and mulching.

Its cast-iron sleeves ensures that the engine lasts a long time even after rigorous and regular usage (providing you look after it properly).

There is also the availability of overhead valves which enables it to consume less fuel without comprising on power or performance.

The Starting System and Transmission

The John Deere D125 comes with an electronic ignition system with a first-time start every time.

Users of this tractor model also get an infinite choice of speeds. The hydrostatic transmission of its engine makes this possible.

You can mow forward at speeds up to 5.5 mph. The D125 also has the ability to mow in reverse at speeds up to 3.2 mph.

All-in-all the JD D125’s transmission matches the cutting performance of the lawn tractor and with a rear tire size to ensure good traction as well as an excellent performance.

 

Cutting Deck and Blades

The cutting deck and twin blades make it possible for grass to be cut evenly at a variety of heights.

This mower’s cutting deck can be lowered or raised by the use of a simple lever within easy reach at the side of the machine by your foot.

D125 cut height adjustmentIt offers 13 cutting positions.

The mower offers side discharge as standard with the option for bagging and mulching.

The mower deck is made of steel with a large a cutting width of 42 inches.

The quality of cut is what you would expect from a John Deere mower.

However, the reverse mow at speed is not quite as good as the machine achieves when mowing at higher forward speeds.

Although the D125 performs excellent when mowing at top speed while going forward it does not achieve the same professional results whenever mowing at top speed.

If you plan to mow in reserve it is advisable to keep your speed below 2 mph to avoid scalping. Lower speed reverse mowing will give you the same quality of cut that forward mowing does.

 

Additional Specifications

The frame of the chassis is made of full-length welded steel.

It has a standard steering wheel and a turning radius of 18 inches. Be careful with your turns when cutting at higher speeds. It is best to reduce speed when turning especially when you are cutting in reverse, as we mentioned earlier.

Below are some of the best features available on the D125.

  1. Gas Powered
  2. Cruise Control
  3. Cup Holder
  4. Headlights
  5. Hour Meter
  6. Key Start
  7. Mulching Lawn Mower
  8. Single-lever Height Adjustment
  9. Deck Wash

The deck wash is standard across the John Deere lawn tractor range and is very easy to use as demonstrated in the video below.

Performance

John Deere lawn tractor reviews prove that these lawn tractors perform at a high standard. Take the cruise control system as an instance.

The John Deere cruise control allows the operator to concentrate on mowing with less focus on driving.

John Deere D125 cruise controlThe mower also moves in a reverse direction seamlessly though as we already mentioned be careful of scalping the lawn if you are cutting at top speed in reverse.

The D125 also offers a choice of side discharging, bagging, or mulching and gives excellent quality results in each of these areas.

Its weight does not stop it from reaching 5.5 mph quite easily at forward speeds and 3.2 mph in reverse.

The high back seat ensures that the operator is always comfortable regardless of terrain or length of operation.

Put simply, there are so many things which this lawn tractor does well we don’t want to bore you with them; technical specifications can sound great but they rarely let you know what to expect from a machine.

We think the John Deere D125 is just about top of the pecking order for a machine in its class. For a 42″ lawn tractor is unequaled and only the Cub Cadet XT series comes close.

How the D125 Compares to Close Rivals

 

Comparison With D110

The D125 model is basically a small step up from the D110. The D125 offers more power than a D110 model.

John Deere D110The small difference between the D125 and D110 is in Horse Power.

The D125 model generates 20hp compared to the 19.5hp of a D110 model. This equates to 540cc in the D110 engine and 656cc in the D125.

The reason the D110 generates fewer horsepower is that it operates on a single cylinder engine compared to the 2 cylinders on a D125 model.

One other notable difference is in the difference in weight between the two machines.

The D110 has a weight of 423lbs slightgly lighter than the D125 model’s weight of 436lbs.

There is also no California compliant D110 model while there is a California compliant D125 model.

Comparison With D140

The next model closest to the D125 is the D140 model.

John Deere D140To begin with, a D140 John Deere lawn tractor is just a slight upgrade to the D125.

The D140 weighs more than its D125 counterpart. While a D125 weighs 436lbs, a D140 model weighs 479lb. And the differences do not end there.

The D125 model has a John Deere branded engine that produces 20hp, while the D140 model produces 22hp. This means that the engine of a D140 model is more powerful than that of a D125 model but not by much.

The biggest difference between the two mowers is the deck size.

The D125, like the D110, has a 42″ cutting deck while the D140 has a much bigger 48″. This means finishing your lawn work happens a lot quicker.

Summary

Our D125 review reveals the high level of performance and fantastic quality of cut offered by this John Deere lawn tractor.

The D125’s ability to side discharge, bag and mulch makes it a great all round lawn tractor. Building on the already excellence offered from the D110 the D125 takes that excellence just a little bit further.

In truth there isn’t much difference in these machines but the V-twin in the D125 makes it well worth the extra 100 bucks; a very small price difference for extra power and heightened performance.

Woman on John Deere D125

Truly the D125 stands out from the competition – both within the John Deere range and among its closest manufacturing competitors.

John Deere continues to look after the interests of its consumer-base through, not only the constant improvement of their mowers but, by offering a Free White Glove Service with the purchase of their lawn tractor mowers.

The White Glove Service is just a fancy name for great free customer service add on; the company sends a trained member of staff to your home to bring them up to speed on how to use this mower and get the very best from it.

Even if you are a seasoned pro at using lawn tractors this service is well worth using as some of the people they send out are very competent and highly skilled and they know John Deere inside-out, so you may learn a few things you did’t know before.

Obviously if this is your first use of a lawn tractor we urge you to take advantage of this service.

Final Thoughts

The free White Glove Service clearly shows John Deere’s willingness to go that extra mile in their drive to stand out as the leading manufacturer of powered lawn mowing equipment and demonstrates their commitment to their customers. Something that cannot be said of all manufactures!

As for the quality of cut, well it is exactly what you would expect from a John Deere lawn tractor.

The high-quality dual cutting blades, 42″ stamped deck, that offers a max 4″ cutting height, and its easily reached height lever gives excellent cut quality even on hilly or uneven terrain.

The only drawback to this machine that we can see is the quality of cut when mowing in reverse at top speed. Put simply, don’t do it!

Cutting at higher range froward speeds is fine but when you mow in reverse over 2 mph you can expect some scalping to occur. Keep your reverse speed below 2 mp when the deck is engaged and you should be fine even on hilly or uneven terrain.

John Deere D125A great feature is the cruise control.

The operator can easily concentrate more on mowing with the option to use cruise control and with D125’s custom comfort high back seat this feature does not mean you have to compromise on comfort.

A comparison with other models of John Deere’s lawn mowers reveal that the D125 model has all the basic features of the popular D110 but with that little bit of extra power that makes a lot of difference in feel and time spent mowing.

With the added cruise control option coming as standard this makes the D125 a much better choice over the D110 as it costs just $100 more.

The customer service delivery of John Deere company is truly second to none! This combined with the capabilities of this lawn mower model makes it well worth the investment.

All-in-all this is one high-performing lawn tractor and possibly the best in its class (we also like the Cub Cadet XT LX42 but the D125 just beats it to the post due to its superior engine performance and John Deere’s exceleent customer service).

We highly recommend the John Deere D125 to anyone who has 1/2 acre to 2 acres of land especially if you have some uneven or steep terrain to deal with.
