A tiller is a machine with rotating blades that helps break up the soil. The most popular name for this machine is rototiller, an abbreviation for rotary tiller. There are gas-powered and electric tillers available. Smaller, self-propelled walk-behind tillers are great for weeding in between garden rows, while larger tillers attached to tractors and are used for churning and mixing up topsoil. The John Deere 450 is a part of the 400-product line of discontinued tillers.

The rotor has revolutions per minute (rpm) of 238. The rotor tip speed runs at 903 feet per minute, or 276 meters per minute, making it a great tiller for breaking up soil quickly and efficiently. The 450 has a maximum tilling depth of seven inches.
The 450 tiller has sealed rotor ball bearings and large replaceable tines. It features a heavy-duty tubular line shaft that gives it more durability. It's side-shaft-driven design gives it more evenly spaced tines with a 50-inch width. The 450 has a three-point hitch and can be lowered and raised by the tractor's accessory mechanisms.
