The John Deere website is the first place to look for information on new or non-current late model equipment. There is a selection tool which gives you a good starting point when determining your needs. When buying used, you need to be flexible. If you find a tractor priced to sell which is more than you need, as long as it fits in your garage and between your trees, why not? The difference in maneuverability between a 12 horse, 38″ mower and a 20 horse 54″ mower is not as significant as say, a Ranger shortbed vs an F350 crew cab. It’s not like gas mileage is a factor. For information on equipment made in the 70s and 80s, check out weekendfreedommachines.org . But the best source of research I found were the actual Internet ads. Sellers like to focus on the features and details which make the product attractive to you.
After months of window shopping, These are the widely produced series I narrowed my choices down to:
Old 200 series (210, 212, 214, 216)
These tractors were made in the 70s and 80s. They were made for more than just mowing, with a vario-drive (infinitely adjustable) transaxle (belt driven) which handles tilling, plowing, etc. The model number reflects the horsepower (210=10hp). These tractors have a countersprung mechanical lift assembly which uses a lift rod to raise and lower rear mounted implements such as a tiller or sleeve hitch (a hitch which can be raised and lowered for using plows, cultivators, etc, sort of like a 3 point hitch). The lift rod is an option which may not come with the tractor, but is easily added. They have an enclosed rear frame. Earlier models have a screened engine cowling; later models have a louvered cowling. Electric PTOs were available. For a good working model, expect to pay $700-1200.
90s GT 240/245/265/320 series
These tractors were the second generation 200 series, which featured mostly Kawasaki engines, and offered a hydrostatic transmission in the 245 (14hp),265 (17hp) and 320 (liquid cooled). The lift mechanism and hand-speed control moved to the right fender, which is a love-it-or-hate-it setup. The 320 has a hydraulic lift. These aren’t the most sought after tractors, and there is very little information about them on john deere’s website.
Late model GT200 series 225
Similar capabilities to the old 200 series, features an electric PTO, hydrostatic transmission with convienent foot controls. 15-20 hp 1 and 2 cyl Kohler and Briggs engines. These have a countersprung mechanical lift system, first hand operated and later foot-operated. Big upgrade from the LT series is the tuff torq K71B transaxle, which is belt driven but extremely strong. Some have hour meters. Closed rear frame, fully welded. I found a nearly mint condition GT225 to maintain my lawn which I am absolutely satisfied with. See my review. Price generally ranges from $1500-1800 for single cylinder, $2000-2500 for twin cylinder (with a 48″ or 54″ deck).
Old 300 series / 318 / 330
Big brother to the old 200 series, these tractors benefit from hydrostatic transmissions (hand operated) and hydraulic deck lifts. The flagship of this line, and probably the most sought after John Deere garden tractor is the mighty 318. This tractor is shaft driven, with an 18hp Onan engine (hard to find parts for). It incorporates dual spool hydraulics, which allows you to use the optional power lift/angle blade (very common on Internet).These tractors have an open rear frame, and a category 0 3-point hitch and rear PTO are available. This opens up a whole new world of utility. It also has dual rear brake pedals, which allows you to turn on a dime or stop a spinning tire to transfer torque to the tire in contact with the ground. 318s in good condition generally go for $1800-2500. Most but not all old 300 series have power steering, evident by the actuator behind the left front tire. Later in the series came the 322 and 332. The 322 was basically identical to the 318 but had a 3 cyl water-cooled Yanmar gas engine. The 332 has a 3-cyl diesel. These tractors are more in the $2800-4000 range. The 330 diesel is similar to the 332 but no power steering and single vice dual hydraulics. Any diesel in good condition under $3,000 is a great buy. There is a John Deere loader available for this series.
Late model GX300 series
Similar to the GT series, but add a hydraulic deck lift (note the lack of a lift handle poking up the left side), all 2 cyl engines. Same K71 transaxle as GT series, but with a differential lock. Significantly higher pricetag than GT series. These are comparable to new X500 series, but with power steering (so they’re better). Mostly going for $3500-4500.
Old 400 series
Pushing the boundary between garden tractor and compact tractor, the 400 was a beast, with a wide stance, differential lock, three spool hydraulics, and the big one: high and low range. Three point hitch, rear PTO, front end loader, etc available. Made for big jobs and probably bought by a commercial user (farmer or landscaper) who pushed it to its dying breath–then revivied it for a quick sale on Internet. It’s rare to find one of these which didn’t live a rough life. If you can find one in good shape, I’d expect it to be around $2000-2500.
The 420 is a beast of a tractor, with a 20hp engine, available 3pt hitch dual hydraulic ports (like the 318) for the power angle/lift dozer blade, hydro trans, hydro deck lift, power steering, high and low range, locking differential, shaft-driven deck. Just a big, mean green landscape maintenance machine. 430 is the diesel version. I’d expect to pay $2500 to 3000 for a solid, well-used private-owned model.
425 445 455 series
After the old 400 series came these bad boys. Four-wheel steering was an option, in addition to power steering and available 3 pt hitch. Hydraulic deck lift standard. Also features a foot-operated hydrostatic tranny. Most have a 54″ or 60″ deck. These monsters also have a 47″ 2-stage snowblower available, and a front-end loader. 425 has a 20hp Kawasaki 2cy; 22hp for the 445; 455 is the 22hp diesel version. I’d expect to pay $2500-3500 for one of these.
Late model X series
As the 400 series evolved, so was born the X400/500 series (now known as X700). Larger than GT or GX series, 4×4 available, 4wheel steer avail, diff lock, limited (height) category one 3-pt hitch available, front end loader, 3-pt shaft driven tiller… Basically the most capable residential use garden tractor on the planet. Big bucks (way out of my price range). Most of these come off the showroom floor optioned well over $10,000. You might be able to get a 2wd for half that now. This tractor bridges the gap between lawn mower and compact tractor, but leans toward the ultimate mower side, with less turf damage (none) compared to a CUT. The price can vary widely on these, based on the options. They are mostly in the $5500-9000 range. Note the spikey heavy duty all purpose tires (HDAP) which give better traction than turf tires, but don’t tear up your grass like bar tires (these are available on the new X500 and X700 series).
Lemon Goggles
Guys who care about their stuff don’t leave it out in the elements. You want to buy a tractor which has been kept in the barn, garage, or shed its whole life. There are plenty of them out there. Showroom-shiny paint on a 25 year old tractor is a bad sign. Don’t buy some old rust bucket which sat out in a field for ten years, got spray painted with a rattle can then placed on auction–these tractors are powder-coated from the factory. Unlike cars, northern tractors tend to be less rusty, due to being more likely kept inside. Be weary of “complete restorations.” You don’t know what it looked like before they started, or if they knew what the heck they were doing. Ideally, you want a tractor which shows its age, but also shows the care it was given. On a 20 year old tractor the paint should not sparkle, but it should still have a little shine to it. The paint should be worn away on the footrests, with maybe a little surface rust “patina” in that area. The seat should have some minor cracks in the corners, and you should expect the sides of the deck to be a little scuffed. But that’s about it. The old guy who sold his house with the big yard to live in a retirement home is the perfect seller (I found him). The seller who claims it ran when it was parked in ‘92 and has the engine cowlings and deck somewhere in the yard is not the ideal seller. Preferably, the deck should be free of holes or welds. The blades are replaced as they wear away, but the deck sheet metal eventually thins and corrodes from the inside out on high-time machines (it’s only 0.1″ thick to start with) Most high-end tractors have hour meters. What constitutes low hours on a lawn tractor? Any premium John Deere garden tractor should last 1500 hours without any major rebuild.
