How to Adjust the Belt on a Troy-Bilt Rototiller

Troy-Bilt makes a variety of rototillers used to cultivate soil. The metal tines on the front of the machine are used to break through thick, heavy soil. Tilling soil creates better aeration and relieves compacted soil, which promotes better plant growth. For a Troy-Bilt tiller to work efficiently, the belts need to be tight. According to the Troy-Bilt manual, new machines will need to be adjusted after the first two hours of operation and then every 10 hours after that.
