Truck mounted units with single-person operation are the most cost-effective, productive and fastest means to keep the streets and stormwater systems clear of leaves and other trash, allowing you to get more done in less time and less trips to the dump.
One ODB DCL truck mounted unit can do the work of 2 self-contained trailers or 3 tow-behinds. (See chart.)

This reduces manpower and fuel requirements (and costs) by multiples. But most importantly, fewer operators on the street significantly reduces safety risk, liability and worker fatigue. (Your neighbors will appreciate the reduced emissions and noise as well.)
