Some Details of the Powerpropelled Cable-ploughing Machines, Tractors, etc., Seen Last Week at the Royal • Agricultural Hall, London
VIROM the point of view of readers of this journal, perhaps the most interesting exhibits at the Smithfield Club Cattle Show held last week at the Royal Agricultural Hall, Islington, London, were the 141eLaren and the Fowler eable-ploughing Machines. Neither of these outfits is new, but both give cause for reflection upon possible developments of the Diesel type engine, not only for farm work but for road haulage of various kinds.
The McLaren machine has the wellknown Mctianen-Beuz 60 b.h.p. Diesel engine, this being a four-cylindered unit of 135 ram. bore and 200 min. stroke. The gear ratio for the cable windlass, as well as that for travelling upon the road, can he varied by fitting different gearwheels, the change-over being a simple operation. The other machine, namely, the Fowler ploughing engine, bas a 70 13.11p. Diesel-type power unit which has six cylinders, three gear ratios being available for Ploughing and for travelling.
The Rushton Attracts Notice.
Another machine which attracted a good deal of attention was the latest type of Rushton tractor as manufactured at the Walthamstow works of the litishton Tractor Co. (1920), Ltd. Two typeswere exhibited, namely, the standard agricultural model which sells at 1198, and the Roadless type, with a special kind of endless track (which forms the subject of a British patent), this selling at £380. So far as the power unit and transmission are concerned, these are of the same type in both models, the engine having four cylinders of 4i-in. bore and 5-in. stroke.
Other petrol-driven agricultural tractors on view were the Wallis, shown by Massey-Harris, Ltd., of London, and the International machine staged by the International Harvester Co. of Great Britain, Ltd., also of London.
There were also two examples of the Case tractor, these being exhibited by the Associated Manufacturers Co. (London), Ltd. The 26-40 h.p. model which weighs 2 tons 3 cwt. has for some time been available in this country, but the 17-27 h.p. model, which weighs 30-cwt., has only been on sale in Great Britain for a short time and has never before been shown here at an exhibition. Readers will remember an article, describing it in detail, which we pub, lished some months ago.
The' liemiy steam side was well represented by several old-established manufacturers. Fodens, Ltd.; of Sandbach,
exhibited the standard 6-ton compoundengined wagon which has three speeds; it is equipped with a winding drum and 100 yards of steel-Wire rope. Near by was to be seen the 7 n.h.p. steam tractor shown by Marshall, Sons and Co., Ltd., of Gainsborough ; this has a waterlifter and winding drum. Wm. Foster and Co., Ltd., of Lincoln, showed its 5-ton compound steam tractor equipped with rubber tyres and three-speed gear ; this machine also has a winding drum , and 50 yards of steel rope.
Other Steam Exhibits.
Three other exhibits in the steam class were those of Charles Burrell and Sons. Ltd., of Thetford, Wm. Allchin, Ltd., of Northampton; and Aveling and Porter, Ltd., of Rochester. The first of these concerns showed a single-eylindered steel-tyred traction engine of the two-speed type.
The machine shown by Wm. Allebin, Ltd., was a 6-7-ton lorry with overtype compound engine ; it was equipped with Allchin. hydraulic three-way single-ram tipping gear. This company's patent two-pin drive is worthy of mention,, since it affords quick detachability for the road wheels.
The steam tractor shown by Aveling and Porter, Ltd., was of the rubbertyred sPring-mounted kind, suitable for hauling 14 tons.
A six-wheeled -Garrett steam wagon. for 10-15-ton loads and equipped with three-way hydraulic tipping 'gear was exhibited; it has two high-pressure cylinders of the poppet-valve kind and a two-speed gear. A good feature of the Garrett wagon is the accessibility of the boiler tubes for cleaning, and the vehicle is found to be very light on tyres; the solid-rubber tyres on the bogin can be reckoned to give at least
30,000 miles of useful service. The Suffolk Punch tractor which attracted attention at the recent Olympia Show was also seen on the Garrett stand.
Wallis and Stevens, Ltd., of Basingstoke, showed its 7 n.h.p. singlecylinder steel-tyred steam tractor, a machine which has a sprung rear axle. We ought not to omit mention of the small petrol-driven cultivating machine shown by George Monro, Ltd., of Waltham Cross. The new 15 b.h.p. Sinter Rototiller is an extremely useful little outfit for light tillage work ; it has a four-cylindered engine, a gearbox providing four forward speeds and reverse, and it sells at 1198. Another new model shown by this company is, the Duotran single-eylindered. two-stroke surface cultivator, this. selling at the moderate price Of. 140. One 'of the wellknown 5 h.p. Models Was also see*. c45
