The boom can be adjusted according to the the right angle to attain the needed cut and depth.
Wheel trenchers are the ones mounted on tracks or rubber tires so as to help with the excavation process. These are quite popular trenchers that are faster in finishing the job and are cheaper than the chain trenchers to operate.
