The house we are moving into next month has about a 1/2 acre lawn (just a bit much for a push mower). Never had a large lawn so I never had a riding mower or garden tractor before. I bought a 1999 314-8 w/ 48" SD mowing deck from a co-worker for the lawn. The wife wants to try gardening, which is another new thing for us. Is it worth getting a 79370 tiller attachment for a small vegetable garden? Small is defined as 10' x 10' to start with this year. If the garden is successful and she maintains the enthusiasm, I'm assume the area could double or triple next year. Advice?
