If you have an acre or two to spare consider running a composting operation as a side line. You can get leaves & grass from landscapers & charge a disposal fee. Most large stables also pay to get rid of manure. Mixing & managing compost piles is a batch type operation which might work well with your schedule. My BIL does this & sells all the compost back to the landscapers in bulk, by the yard. Could do even better if he bagged & sold retail. Runs his operation with a Bobcat & single axle dumptruck. His biggest drawback, IMO, is his sales are seasonal spring & fall, while production is year round. This takes up more room as he stockpiles leaves & clippings to match his manure supply which is more steady. MikeD74T
