Self-contained diesel engine-driven vacuum leaf collecting machines. The leaf collector is trailer mounted, designed for one-person operation, and capable of picking up and completely mulching leaves from curb sides, median strips, ditches, open spillways, and other areas, then depositing the mulch in an integral 17-, 25- or 30-cubic yard hopper. Also offered is a line of convertible (right or left pick-up) trailer-mounted, power-driven, vacuum leaf-loading machines. This tedious task just became a lot easier to overcome with this machine. The machine mulches the leaves and deposits them in the bed (hopper) of a tow vehicle. Many custom features are available including permanent factory mounting on a variety of truck chassis.
