A natural John Deere hobbyist, I am learning and researching about the various models and sharing my tractor findings.

The John Deere 318 lawn and garden tractor, though now discontinued, is said to be one of the best John Deere lawn tractors ever built (if not 'the' best). In fact, many owners bought their model brand new and still work it hard 15 to 25 years later. I have even heard of a fair few trading in newer JD lawn tractors model for the more hardy, reliable JD 318 (it is that good).

The general view (thrown in with my own personal experience) tends to be that they are obviously very dependable, heavy duty and rugged. Minimum maintenance is required, and it will practically run a lifetime with a lot of custom and official attachments being available for them. In sum, basically an excellent all-around lawn and garden tractor.

The downsides aren't really regarding the tractor itself, but are more to do with it being such a well-known, reliable but discontinued product. It is pretty darn difficult to find one for sale (which is understandable, as people will just want to hold on to it). Moreover, finding replacement parts can be difficult and sometimes jaw-droppingly expensive.

John Deere 318 Specs

Here's a quick rundown on the specifications of a 318 (for a more detailed overview, please be sure to take a look at the video review just below):

The 1986 factory built (i.e unmodified) John Deere 318s tended to have a 4.5 gallon (17.0L) capacity with a 1.2 gallon (4.5L) hydraulic system. The Onan B43G 18 horsepower, 2 cylinder, 4 valve engine runs on a 12 volt battery.

With hydrostatic steering, this sturdy tractor, unmodified, runs about 8 mph at top forward speed and 3–6 mph in reverse. The wheelbase is 46 inches and the entire base model is 836 lbs (379 kg). It stands 44 inches in height, just over 3.5 feet tall.

In-Depth Review of the John Deere 318

Available Add-Ons and Attachments

The 318 also has a lot of available 'add ons' and official attachments available such as:

Mower Decks

  • 36" hydraulic 2 blade mower deck
  • 46" hydraulic lift 3 blade mower deck
  • 50" hydraulic lift 3 blade mower deck

Snow Blowers

  • 46" single stage hydraulic lift snow blower
  • 47" dual stage hydraulic lift snow blower

Bucket Loaders

  • 48" 500 lb 0.21 cu yard bucket loader
  • 54" 500 lb 0.24 cu yard bucket loader

You will also come across modified attachments for sale too, such as a 3 point hitch, front mount broom, rear blade, hydraulic lift blade, rototiller, garden tractor cab and a utility cab.

How Much Do They Cost?

Pricewise, it will obviously depend on the condition and its age. But a general guide price to be looking at is between $1200 and $2000 for a decent secondhand, unmodified base model.

Where Can You Get a John Deere 318?

As with most vehicles, whether you are buying a 50cc ATV or a full on tractor, research into the market is certainly required. The first point of call should be to check secondhand sales sites including CraigsList, eBay and sites such as; local newspaper classified ads are always worth checking, too. Even posting a note in local farm shops and the like stating you are interested in buying such a model should generate some interest from a potential seller.

Finding Parts

As the model is discontinued and most owners loyally hang on to them until the bitter end, finding parts for the John Deere 318 can be difficult. You can search your local classifieds (online or newspaper), or have something shipped from further away, which will be more costly. Amazon sells some of the more commonly needed parts such as alternators, switches and replacement engines. For Onan engine parts, try their website. If you are still finding no luck, try posting in one of many tractor- and garden-related message forums online.

Buying Tips

First, look for general wear, leaks at the rear axle or under the motor. Also look for dents to the hood or broken tail lights. Check the motor fluids; check the mower deck for dents, tears or cracks; check for leaks at the rear axle or under the motor. You want to know if the current owner took care of this tractor and kept it well maintained.

Questions to ask yourself before you buy:

  • Is there a lot of rust?
  • Does it start easily?
  • Do you see smoke when it is running?
  • Are there unusual noises?
  • Is there excessive vibration?
  • Are grass clippings packed in the engine compartment and/or the rear axle?

If you find any or all of the above, it may indicate that the owner did not maintain the tractor with care. This could mean that there are more issues which may not be obvious. Lastly, find out how many hours the tractor has been run. I have read in several places (and have been told) that you could expect to replace some parts every 500 to 750 hours or so on average.

Operator's Manual, Parts Catalogs or Technical Manuals

If your tractor does not come with an operator's manual, you can purchase one directly from John Deere. Visit the John Deere Technical Information Book Store for any manual not available digitally.

If you are looking for an incredibly sturdy and reliable lawn and garden tractor, the John Deere 318 is a great choice. The only downfall of this hard-working tractor is finding and paying for replacement parts. Keep in mind that replacement parts for many tractors are expensive despite the brand or model. This John Deere model, however, is extremely popular and most people who have used one have nothing but good things to say about it.

There are also variants of the 300 series to consider. For instance, the John Deere 332 is the diesel version that came out a year or so later for the 318. It takes on almost the exact same components, however, just runs on diesel as opposed to gas like the JD 318 does. Of course, there are newer models to consider too - such as the John Deere 425.
