Tiller attachments, the components connected to farm tractors, are available used on auction sites and stores that sell similar used equipment, such as eBay or TractorHouse.com. These sites contain new and used listings for tillers, with prices and year models, some only available for auction and some available for purchase.
Tillers are made by companies such as Belco, Howard, John Deere and Land Pride. Many of the attachments available for purchase are larger models made for major farming tasks, but some models are available for home usage. As of 2015, some John Deere tiller attachments are available on appropriate auction sites, with prices that open at $100. However, tillers for farmland work tend toward costing tens of thousands of dollars, and are much larger than what is appropriate for personal usage. Only a handful of models are available for less than that.
On eBay, tiller listings for smaller use range about $1500, and may fall lower or higher than this by a significant amount according to the model's age and quality. Tiller components, such as tiller blades, may cost around $30 dollars, also depending on these factors. The tillers found on eBay tend toward being the smaller models, around 5 feet across in some cases. TractorHouse.com lists a much larger amount of major farming tillers, a large contrast to the stock available on eBay.
