Abstract:
A spray cart comprising:a) at least two suspension assemblies each comprising at least two wheels, each of said wheels mounted to the suspension assemblies so that the wheels swivel, said wheels being offset from their mounting so that the wheels trail their mounting,b) a main frame assembly to which each of the suspension assemblies are secured by means of a pivot shaft so that each suspension assembly rotates with respect to the main frame assembly, said main frame assembly capable of carrying a tank filled with liquid,a limiting stop on an outer travel limiting collar of a suspension assembly bushing, andan inner travel limiting stop on a journal in the main frame of the spray cart,wherein the limiting stop on the outer travel limiting collar of the suspension assembly bushing acts in conjunction with the inner travel limiting stop on the journal in the main frame of the spray cart to limit the rotation of the suspension assembly about the pivot shaft,c) a hitch assembly connected to the main frame that provides a means of towing the spray cart, said hitch assembly further comprisinga hitch holder with hitch pin clearance,a hitch insert with pin clearances, andfront hitch insert mount pins,wherein the hitch insert can be raised or lowered in the hitch holder and then pinned into position thus varying the distribution of weight of the spray cart on the wheels,d) a rear hitch,e) at least one plate suitable for attaching an adjustable length stabilizer bar suitable for connection to a subsequent towed vehicle,f) a tank for carrying liquid,g) hydraulic/liquid throughput lines,h) a gauge visible to an operator of a towing tractor while the operator is operating the towing tractor, andi) a tongue assembly that, in combination with said hitch assembly, permits a variation of weight distribution of the spray cart on the wheels by adjusting the elevation of the hitch holder with respect to the hitch insert.
