What’s The Difference Between John Deere 300 and 500 Series Based on Features?

1. Dimension

John Deere 300 series tractors typically weigh between 500 and 550 pounds. It features a narrower track width compared to the 500 series.

On the other side, the John Deere 500 series weighs between 655 to 720 pounds and compared to the 300 series has a larger track width.

The 500 series lawnmowers can cut more grass at the same time because it has a bigger width.

As a result, they can cover more ground because they have a bigger cutting deck. This means that when it comes to build quality, the 500 series lawnmowers will be a long way ahead of the 300 series lawnmowers.

2. Tires Size

The 300 series lawnmowers come standard with a front tire measuring 15×6.00-6 and a rear tire measuring 20×10.00-8. 

The 500 series lawnmowers come standard with a front tire measuring 16×6.5-8 and a rear tire measuring 24×12-12.

The 500 series lawnmowers cover a bigger surface area than the 300 series lawnmowers due to the increased tire size on both the front and rear tires. As a result, the 500 series will triumph in terms of tire size.

3. Mower Deck

For the 300 series lawnmowers, three different mowing deck options are available. Mid-mount mower decks are typically 38″ in length, 42″ in length, or 48″ in length.

On the other hand, there are two mowing deck options available for the 500 series lawnmowers. Mower decks with a typical width of 48″ and 54″ are available as mid-mount mowers.

In terms of cutting deck size, the bigger cutting decks of the 500 series are preferable for mowing more grass. Due to their increased size, they allow you to cut more grass in less time by making fewer passes over it.

As a result, the mower deck performance of the 500 series lawnmowers will triumph over the 300 series lawnmowers.

4. Engine Capacity

The 300 series lawnmowers are powered by engines capacity ranging from 17 to 22 HP.

Whereas the 500 series lawnmowers include engines capacity between 25 to 26 HP.

Therefore, the 500 series lawnmowers are preferred in terms of engine capacity over the 300 series lawnmowers.

5. Transmission

The transmissions used in the 300 series lawnmowers are the Tuff Torq K46, and Tuff Torq K58. 

The 500 series lawnmowers, on the other hand, are equipped with a Tuff Torq K72B or K72C transmission. The Tuff Torq K72B and K72C transaxles include upgraded materials and unique features that come together to make them the most durable and powerful.

The 500 series lawnmower’s Tuff Torq K72B and K72C transmissions include a number of additional features, and these transaxles are as dependable as they are powerful.

So, in terms of transmission, the 500 series will be the easier of the two series to choose.

6. Displacement

The 300 series lawnmowers use a 472 cc engine. This indicates that the engine’s cylinder volume capacity is 472 cubic centimeters.

On the other hand, the 500 series lawnmowers feature a 675 cc engine. This indicates that the engine’s cylinder volume capacity is 675 cubic centimeters.

Without a doubt, the bigger the cylinder, the higher the capacity for air and fuel absorption and, thus, the larger the cubic capacity. Thus, when the displacement values of the two engines are compared, the 500 series lawnmowers outperform the 300 series lawnmowers.
