I'm looking for recommendations for the best (most useful) attachments for the BCS model 739. We are planning to purchase it new this year and probably only afford one attachment this year.

A bit of background: we have 1.5 acres of market garden, small, slightly unreliable rototiller, and a 1951 Farmall C with plow and discs. We hope to move away from much tractor work and all the ground we will be working is previously broken by the tractor. We grow in 4'x100' beds.

Thanks, Lorraine
