other means which can be placed upon implement 10 anhydrous ammonia or liquid nitrogen can be applied by mounting hoses directly behind chisel plows 32 supply tanks can be carried on tractor 14 on implement 10 or on trailing containers hitched to the implement pumps to convey herbicides or fertilizer can be powered by the tractor 39 s hydraulic system or by rotational power from the tractor 39 s power take off as supplied to gearbox 69 the second mode of implement 10 the cultivator mode becomes operational by removing front and rear tool bars 22 and 84 and hitching tractor 14 to remaining middle tool bar 62 additional tines 114 are added to axles 80 of rototillers 60 to widen the coverage of rototillers 60 weeds are not a problem in the actual crop rows because of the effective incorporation of herbicide when planting in fact weeds are encouraged to grow in between the rows during early stages of growth to deter wind and water erosion at a suitable time after the crops have grown a pass is made with cultivator mode 2 of implement 10 with the rototiller 62 operating at a comparitively lower revolutions per minute so that the weed growth in between the rows is simply cut off approximately just below ground level and the trash in the rows is mulched this leaves additional ground cover again deterring erosion while at the same time cutting down the weeds thus.
