The S.F.I. scarifier, after strengthening, had been "quite successful" for 2 years, promising trials were under way with the cone scarifier and barrel ring scarifier, and development had begun on a new flail scarifier for use on sites with shallow, rocky soils. Recognition of the need to become more effective and efficient in site preparation led the Ontario Department of Lands and Forests to adopt the policy of seeking and obtaining for field testing new equipment from Scandinavia and elsewhere that seemed to hold promise for Ontario conditions, primarily in the north. Thus, testing was begun of the Brackekultivator from Sweden and the Vako-Visko rotary furrower from Finland.

Use of a Seed Scarifier for Detection and Enumeration of Galls of Anguina and Rathayibacter Species in Orchard Grass Seed. Plant disease 87:320-323. In addition to crop loss, A. agrostis associates with pathogenic bacteria Rathayibacter rathayi (formerly Corynebacterium rathayi) to cause annual ryegrass toxicity in Australia.

1 He designed and built agricultural machinery, including the first "stump jump" scarifier that was suitable for the northwest coast of Tasmania.Snare p.9 In 1939 Shaw was granted a patent for "An improved scraper for reversible disc ploughs". This plough was never commercialised though some prototypes were built and used.

Some graders have optional rear attachments, such as a ripper, scarifier, or compactor. A blade forward of the front axle may also be added. For snowplowing and some dirt grading operations, a main blade extension can also be mounted. Capacities range from a blade width of 2.50 to 7.30 m (8 to 24 ft) and engines from 93–373 kW (125–500 hp).

Not only did he invent a stump jump plough he also invented a cultivator, slasher, scarifier and double furrow plough. Stott and Mellor Brothers, who had refined Stott's design, were jointly the first to patent a stump-jumping plough in Victoria. A working model of the R.B. Smith Double Furrow Plow is held by the Powerhouse Museum in Sydney. It is very finely crafted and was made in 1883 by Albert Arnold, then a young Journeyman blacksmith.

The front and rear rolls were usually fitted with scraper bars. As the vehicle moved along, these removed any surface material that had become stuck to the roll, to prevent a build-up of material and ensure a flat finish was maintained. Some steam rollers were fitted with a scarifier mounted on the tender box at the rear. They could be swung down to road level and used to rip up the old surface before a road was remade.

It is sown as quickly as possible after the removal of a grain crop at the rate of 20–22 kg/ha. It is found to succeed better when only the surface of the soil is stirred by the scarifier and harrow than when a plowing is given. It grows rapidly in spring, and yields an abundant crop of greenery. Only one cutting, however, can be obtained, as it does not shoot again after being mown.

Brochures further claim that in wet conditions, the water passes more easily through the shattered areas, reducing the possibility of crops drowning. Agricultural subsoiler implements will have multiple deeper-reaching blades; each blade is called a scarifier or shank. Purdue University's Department of Agriculture indicates that common subsoilers for agricultural use are available with three, five or seven shanks. Subsoilers can be up to wide; some models are towed behind tractors while others are mounted to the three-point hitch.

Lawson decided to commence farming from a modern perspective and as such placed great emphasis on the inventions of the new industrial age, with particular reference to steam cultivation. In February 1862, No 95 of John Fowler's Patent Steam Ploughing Tackle arrived at Aspatria railway station. The affectionately named ‘Cyclops,’ the first of its kind in Cumberland, comprised a portable steam engine, with the capacity to drive a grubber, plough, cultivator, and scarifier. Once unloaded, the 10-ton curiosity astonished onlookers when it travelled along the road without the aid of horses.

During the Daily Telegraph expenses scandal it was revealed that Ottaway claimed for a second home nine miles south of the constituency, with another house minutes from Parliament. Ottaway apologised to constituents for his part in 'allowing an indefensible system of allowances to develop' and announced he would let Croydon South party members decide his fate in a vote of confidence. The local association's President, Lord Bowness, chaired the meeting, which ended in a secret ballot that Ottaway won. Among his expenses claims between April 2004 and March 2008 were £59.99 on light bulbs and £48 for modifying a scarifier.

According to J. Hall (1970), in Ontario at least, the most widely used site preparation technique was post-harvest mechanical scarification by equipment front-mounted on a bulldozer (blade, rake, V-plow, or teeth), or dragged behind a tractor (Imsett or S.F.I. scarifier, or rolling chopper). Drag type units designed and constructed by Ontario's Department of Lands and Forests used anchor chain or tractor pads separately or in combination, or were finned steel drums or barrels of various sizes and used in sets alone or combined with tractor pad or anchor chain units. J. Hall's (1970) report on the state of site preparation in Ontario noted that blades and rakes were found to be well suited to post-cut scarification in tolerant hardwood stands for natural regeneration of yellow birch. Plows were most effective for treating dense brush prior to planting, often in conjunction with a planting machine.
