Dad tills up his 20-plant tomato garden with two Troy-Bilt Horse tillers. One is a restored 1977 Troy-Bilt Horse powered by the original 6.0-horsepower Tecumseh engine. The other is a 1975 Horse repowered with an 8.0-horsepower Briggs & Stratton engine. The hard, dry soil is no match for these workHorses.
