Howard Rotavator

Arthur Howard was born on the 4th of April in Crockwell, New South Wales, He built his first model in at the family farm at Gilgandra. He was engineering by correspondence while an at Moss Vale, a town on the highlands of New South Wales, of Sydney.

Of course the Australians Cliff Howard with the of the Rotary Hoe. Rotary dates back to the 1850’s.

working in England during WWI he to Australia in 1919 and started to test and patent his rotary hoe At first his machines were using 40 to 60 HP engines as prime Then he started making hoe attachments for tractors such as the

In 1921 Howard formed Auto Cultivators Pty Ltd. made a variety of different tractors and crawlers from to the 1960’s including the DH22 tractor that was made for 30 and the Platypus crawler.

Howard his attention to a walk behind and by 1924 he produced the 6hp Howard rotary hoe. A model 8 and 12 was reported to have been

In 1928 Capt. E. N. Griffiths Australia, like the Howard and to have one exported to England. He had Howard’s of Bedford, England the machine. Howard’s of Bedford was not to Cliff Howard.

About 100 were made.

In 1930 formed the Howard Cultivators in England to manage export outside of Australia. And in 1938 Howard and Capt. E.N.

formed Rotary Hoes in East Horndon, Essex for the of Howard’s machines in England. The was located on Station Road and the number was HERONGATE 26 and 96. In the early the local authority changed the from East Horndon to Horndon the factory stayed at the facility.

Rotohoe Models

In 1940 the controlled Rotohoe GEM was introduced to the Australia designed and East built Rotohoe 5, 6, 10, and 12. During a variety of engines were to keep the permitted level of going. Even motorcycle from scrap yards used.

GEM Series II

Then in the Series II GEM model was introduced either a Howard BJ (British or a J.A.P. 6hp petrol (that’s to us yanks).

J.A.P. stands for J. A. Co. Ltd. motor works of Both of these engine a dry sump oil system with the oil being located next to the tank. The GEM now had three forward and one gear. The Series II has a single dry controlled by a handle on the handlebar.

A 20 was standard but a 18 and 24 was available.

In 1949 Rotary Hoes, Ltd. importing his GEM machines to the United In an advertisement from 1949 it their machines have used in Australia for many and some 20,000 units in operation.

This is supported by a letter I have from Hoes Ltd. to the man who’s I purchased my Bantam and some of the I have on the Howard’s, it mentions an in Chicago:

The Chicago Fence Co.

4400 Addison St.

Chicago 44, Ill.

This states that in March, there was not an agent in Pennsylvania, but one be appointed soon.

Clifford and Auto Ltd. produced cultivators under the name Cultivators Ltd. from to 1956/59. Howard’s Rotary Ltd. purchased the line of and tooling and the logo Howard-Clifford was for a few years. Like Howard’s of Clifford Cultivators was not related to

Howard. Howard-Clifford became Rotavator Co. in 1959. The names and don’t always match the different sources or they overlapped so a clear cutoff is not evident.

No Cliffords models been reported to me making way to the U.S.A.

GEM Series III and IV

In 1950 the III and IV was introduced. I have some literature and owner manuals 1950. They had car type as described in the sales literature. The is a 4-star quadrant with in the middle. It looks like a sign.

The handlebars could be for height and laterally.

They had a lock that automatically when the miller (tine was place in neutral to make

The Series III has a 600cc 6hp J.A.P. and came with either a 18 or 20 The Series IV has Howard’s own 9.8hp twin cylinder engine and with a choice of 20, 24 or 30 miller. A 9hp Sachs water-cooled diesel was as an option in 1957. Attachments be hitched to the miller cover. A furrower cover, roller, pulley, soil shredder, guard shields and extension was offered.

A PTO pulley was standard and for the soil shredder attachment.

One piece of literature from listed the 600cc engine as and the 810cc engine was listed as The same flyer shows wheels with the extension and has a picture of dual rubber installed in another.

Wisconsin and twin-cylinder engines were to some GEM imported to the U.S. The engines were rated at R.P.M. whereas the J.A.P. at 1800 R.P.M. and the Twin at 2000 R.P.M. Two versions required, a slow-speed and a high-speed

The slower version has a distance of 1.5 inches between the starter and the reverse idler gear the shafts come through the case on the right side. The speed version is about apart

Series V

By the time the V was introduced in 1960 some GEM had been sold. A Howard twin-cylinder 12hp engine the unit and has a 2.8mph top speed. A dry-disc clutch was design.

In the 1970’s new engines choices introduced. Kohler K301T or a Hatz E780 9hp diesel.

GEM and Super GEM

The Series V basically the GEM Standard with little The Super GEM had a choice of a Kohler 15hp or a Hatz E785 diesel.

The GEM became the Dowdeswell 650 in when Howard went receivership and some models sold to Dowdeswell Engineering.

The Howard Models

A collector in has a Terrier with a Howard 4.2hp engine made 1948. Other Terrier has Villiers engine on them.

The was another model not imported to the but I believed it was the bases for the Yeoman in 1955.

In 1950 the Bantam was introduced. It has a 10 miller and was powered by a 1.95hp two-cycle engine. A variety of was used but I have never any literature mentioning them, in the a Briggs Stratton model 5 2hp engine also a four-cycle was installed.

I have a Briggs unit. It has 4 forward speeds, transmission with twin grooves on the engine input Solid rubber tires are A 4 flat-belt pulley is mounted to the drive shaft.

The miller is and attachments such as a toolbar(cultivators), seeder units, hedge cutter bar and cylinder mower be attached.

A sales literature I from 1955 has a $350 written next to it. A price from England in 1956 the Bantam at Ј99.

In 1956 engines choices were in England, Villiers Mark 15 or B.S.A. four-cycle or a Villiers 25c 2hp two-cycle.

Joining the line in was the Bulldog and in 1955 the Yeoman. The was renamed Bullfinch after a with Lanz, a German manufacturer who already used the name. The Bullfinch was a less then the Bantam still a 10 miller but a smaller engine J.A.P. and the handlebars did not swing to the

The Bulldog/Bullfinch would be in direct with the American Roto-Ette. On the Bantam and Bulldog/Bullfinch models the was tilted to tighten the V-belts to the just like on the Roto-Ette T, 2 and 3 series.

The Yeoman is a mid-size with a Wisconsin 8.2hp AEN And two-speed gearbox provided 4 gears, two reverse and two speeds on the 15 miller. A U.S. sales with the Wisconsin engine has hand written on it a price of

Using the same quick system on the miller unit as the the Yeoman offered several including front and rear bars, cutter bars, and seeder units. A Terrier was also made, but I don’t any specs on it.

Cliff Howard in January 1971.

At the University of Sydney, Hawkesbury, Richmond, New Wales, Australia in the Stable is a ‘Historic Engineering Marker The text reads:

Howard’s Hoe

Arthur Clifford Howard developed the first commercially machines for soil cultivation powered rotors. His first was built on the family farm at in 1912. Marketing his ‘Rotavator’ in 1922 from factories in New South Wales and later

The principle of rotary cultivation has adopted on farms worldwide the smallest holdings to home and the largest enterprises.

Cliff also developed tractors and farm equipment over a and productive career. His name on a range of machines sold.

by The Institution Of Engineers, Australia,

Also located at the University is an model Rotary Hoe, but not the It’s located at the Machinery Shed on Clydesdale Lane.

this we get into the Modern Era as I it and I won’t go into any great The Bullfinch had a more powerful installed and renamed the Demon. The became the 200 series, the Yeoman the series.

The 8hp Dragon was introduced.

The West facility was outgrown and closed in A new plant was opened in Ipswich and the changed to Howard Machinery

The GEM as mention earlier had been to Dowdeswell during the receivership in The rest of Howard was bought by and traded as Howard-Farmhand. The Farmhand was later dropped, Howard Co. is still in business but only tractor mount models 40 to 180 wide and rated from to 250hp.

Trivia fact, the Rotavator is a palindrome, it reads the forward and backward, see rotavatoR.

I collected some Sales from Howard used in the This literature not only the machines but also mention the sales offices used at times in America from to the mid-1950’s.

There is two distributors on one color sales literature I This flyer doesn’t a date printed on it, but it states back by 27 years of experience.
