John Deere 318 Tractor Review & Specs

A couple of years ago, at a friend’s party, we were having a tractor talk when some of my friends mentioned John Deere 318 as the best tractor they have ever used by a mile. I was taken aback at first; there must be something here to bring about this consensus among many gardeners. So I set up to investigate. 

In the last couple of years, I’ve borrowed JD 318 and tried it a couple of times. I’ve read countless JD 318 reviews and had longtime users answer my questions. And as you know, I cannot hoard information from you guys, especially one as important as this. 

Please do not believe me when I say John Deere 318 is the best tractor of its time; let me show you why even the fiercest of critics find it difficult to discredit this statement.

John Deere produced JD 318 for ten years between 1983 and 1992. John Deere 318 is a garden tractor manufactured in Horicon, Wisconsin, USA. It preceded JD 317 in the John Deere 300 series. It implemented so many upgrades that have made it so popular even to date. Why has this tractor continued to stay relevant for so many years? Let’s see why below.

John Deere 318 is a lawn and garden tractor that comes in an average tractor size. Its length is 68 inches with a height of 44.5 inches and a width of 43.3 inches, a tad bit smaller than some of the JD 400 series tractors like John Deere 420. Its 17 L fuel capacity gives you a long running time.

Features of John Deere 318


John Deere 318 used two engines during its production year. It started with one then was replaced after a couple of years.

At inception, there was the Onan B43G engine model. This model sports an 18HP gasoline engine with an engine torque of 4.4 kg m. The fast idle engine speed without load is 3450 rpm, while the low idle engine speed without load is 1350 rpm.

Its two-cylinder engine has four strokes and is air-cooled, meaning you do not have to put the engine off to rest for a few minutes now and then. It has an electric starter that will keep you away from the struggles involved in starting a lawnmower with a bad starter. This was the engine model used in JD 318 from 1983 to 1987.

In 1987, John Deere saw the need for an engine upgrade, and they found one in Onan P218, another two-cylinder gasoline engine with 18 HP. This engine has a higher displacement and rpm rating at 781 ccs and 3600, respectively. They both have a starter volt of 12. 


It has a shaft-driven hydrostatic transmission type and Sundstrand series 15 model 90 transmission model. Its hydrostatic power steering type gives you ultimate control and comfort when using this tractor.

It has shoe and drum brakes located on the rear wheels like most John Deere tractors. It also sports infinite forward and reverses gears with a forward speed of 12.4 km h and reverse speed of 6.2 km h.


Tires are essential in tractors because you want to leave a clean job after working in your field. Also, the weight of the tractor needs to be adequately supported. What kind of tires does John Deere 318 have?

The lawn/turf rating for the front tires is 16×6.50-8, while that of the rear tires is 23×10.50-12; 23×8.50-12.

PTO (Power Take-off Shaft)

All the attachments in a tractor would be useless without the right power take-off shaft. It enables a smooth transmission of power to the attachments. What kind of PTO does JD 318 have? 

The front and rear PTOs are both independent with electric clutches. The electric clutch ensures your safety when using the tractor. The front PTO speed without any load is 3450 rpm, while the rear PTO speed without any load is 2000 rpm.

John Deere 318 has a lot of attachments. It can even use JD 140 and JD 300 series attachments, which means if you’re looking to upgrade from the 140, you can still make use of your old extensions.

This tractor’s attachments include snow blowers, front end loaders, blades, 38′ 46′ and 50′ mower deck for any grass size you’re cutting. 

Pros of John Deere 318

It is not regarded as one of the best John Deere tractors ever for nothing. Its features and modification stand out among its peers. 

  • It is durable: this tractor fits in the most unusual of terrains without issues. It doesn’t matter the number of times you use it in a week; it’ll surely give you years of service beyond its price. 
  • It is rugged: talking about unusual terrains; whether you live in a hilly landscape or a landscape with uneven terrains, this tractor will work comfortably in those situations. 
  • Hydrostatic power steering: all the best features without a comfortable tractor will give you so much back pain and stress that you will no longer want to work in your garden anymore. The hydrostatic power steering feature allows for the smooth handling of this enormous machine.
  • Annunciator light: the annunciator light is located on the dashboard and aids your work in the night. The light helps you work at night, whether you’re using the snowblower to clear the heap of snow in your driveway or using the loaders to move heavy equipment.
  • Electromagnetic clutch: the electromagnetic clutches at the front and rear part of the PTO ensures your safety when using the machine.

Cons of John Deere 318

This tractor’s cons are less about its features and more about factors concerning its age and longevity.

  • Parts are difficult to find: this tractor’s age makes it challenging to find its parts and attachments.
  • The tractor is difficult to find: if you’re looking to buy this tractor, it may take you a while to find it because of its age and because owners are less likely to part with this beast of a tractor.

It will last you for a long while handling your garden needs in the most difficult of terrains.
