Manual of JlgricuUure. 475 harrow, especially for covering grass seeds, has been always en- tirely GRUBBER OR CULTIVATOR. These implements, though known under very many names, as 8cuffler8, acarijiera, extirpators, &c., &c., have but one object, and may therefore be considered conjointly under the above caption. The introduction of cultivators as substitutes for the plough is of comparatively recent date. Previous to the nineteenth century they were little known, and by no means generally used. Their adoption has, however, brought about a revolution in the system of cultivation, and in the present day we probably do very much more work with the cultivator in the season than with the plough. The principles to be secured in the construction of these imple- ments are: play to secure an even grubbing of knolls and hol- lows, a tJiorough uprooting of every particle of soil in their pas- sage, the minimum amount of draught to the horses, and the formation which shall ensure a rooting up of weeds and grasses and sods without choking up the machine. To ensure play for hollows and knolls, and to allow of collected sods, weeds, &c., escaping from under the machine after being rooted up, the frame must be hung on the axle, that it may have swing. To ensure easy draught on the horses, the centre of resistance when at work must be known by the maker, and that point brought as near as possible to and in the natural line of the trace and collar. We have seen such grubbers as take too firm a grip on the soil, and enta
