Atco (British mower company)

Made in U.S. (1980–85)

From 1980, Atco Motor Mowers imported lawn and garden tractors made to their designs from the United States.

Atco 8/32E lawn tractor, 1980

The full model range of American-built Atco lawn and garden tractors was:

• 7/32 – 3-speed with reverse, 7 h.p engine, 32" cutter deck
• 8/32E – 3-speed with reverse, 8 h.p engine, 32" cutter deck
• 8/36E – 3-speed with reverse, 8 h.p engine, 36" cutter deck
• 11/36E – 3-speed with reverse, 11 h.p engine, 36" cutter deck
• 16/42E – 4-speed with reverse, 16 h.p engine, 42" cutter deck

The "E" at the end of model number for American tractors stands for electric start; the 7/32 never had electric start but did have recoil start.

Made in Britain (1986–92)

In 1986 Atco stopped production of the American lawn and garden tractors and started producing their own in Stowmarket, Suffolk, in the United Kingdom. The first new model was the 11/36, which won "Best Grass Cutting Machine of The Year" in 1986.

Atco 8/30 lawn tractor, 1988

The full model range of British Atco lawn and garden tractors was:

• 6/30 – 3-speed with reverse, 6 h.p engine, 30" cutter deck
• 8/30 – 3-speed with reverse, 8 h.p engine, 30" cutter deck
• 8/36 – 5-speed with reverse, 8 h.p engine, 36" cutter deck
• 11/36 – 5-speed with reverse, 11 h.p engine, 36" cutter deck
• 12/36 – 5-speed with reverse, 12 h.p engine, 36" cutter deck

The 8/30 and 8/36 lawn tractors were sold with an option of a powered grass collector, while the 12/36 was only sold with a powered grass collector. The Atco 6/30 was an economy model with pull start, no electrical equipment, and a solid mild steel bonnet front.

Atco also made a trailer to fit all models, with a 10 cubic foot hopper which tipped for emptying.

There was a choice of 30" or 36" cutting widths, both having twin blades. 'V' channelling in the deck ensured that grass cut by one blade was not thrown in the path of the other blade. Grass was ejected not from the side, as was common with other tractors, but from the rear. This meant that the non-collecting models could be hitched to a towed sweeper to collect grass cuttings, leaves and other debris.

The tractors had 8 h.p., 11 h.p., or 12 h.p. engines. The 7.25 pint fuel tank provided approximately 2 hours and 30 minutes of continuous mowing. The tractors also featured wide pneumatic tyres.

Atco was the first ride-on lawn tractor to have a powered grass sweeper, driven from a power take-off (PTO) at the rear of the machine. The PTO worked independently of the blades, so the user could cut the lawn without collecting the clippings or vice versa.

Atco stopped making lawn tractors in 1992. When GGP Ltd bought the Atco name in 2011, they started producing new lawn tractors branded Atco.

Commodore – domestic petrol cylinder mower (1986–92)

Available in four sizes of cut: 12", 14", 17" and 20".

Models Numbers for the Atco Commodore were:

• Commodore B12 – recoil start
• Commodore B14 – recoil start
• Commodore B17 – recoil start
• Commodore B20 – recoil start
• Commodore B14 – electric start
• Commodore B17 – electric start
• Commodore B20 – electric start

Electric start models were available from April 1988.

Ensign – domestic petrol cylinder mower (1990–92)

The Ensign had a cushion-grip handlebar that could be adjusted to height and an adjustable comb which lifted flattened stems which might not otherwise be cut. Polished beechwood front rollers allowed mowing up to the lawn edge and could be replaced quickly with sidewheels for cutting long or wet grass.

Fitted with the Atco 144cc engine, the Ensign was available in a choice of three cutting widths: 12", 14" and 17". Key start was available on the 14" and 17" models.

Imperial – domestic petrol cylinder mower (1990–92)

Both front and rear rollers could be individually levelled to maintain alignment between the mower and the lawn. As well as a comb for raising flattened grass, the Imperial had a scraper which prevented the buildup of grass on the steel front roller. A Mitsubishi key-start engine was fitted.

Royale – heavy-duty petrol cylinder mower (1964–2011)

Top of Atco's cylinder mower range, the Royale was designed for large areas of fine lawn. The traditional 6-bladed steel cutting cylinder gave 70 cuts per yard while the heavy duty rollers helped to produce a striped finish.

Early models of the Royale featured a Tecumseh–built horizontal shaft engine with recoil start. Engines in later models were from Briggs & Stratton, with an electric start option introduced during the 1980s. The Recommended Retail Price of the machine just before it was discontinued in 2011 was over £2000, making it the most expensive mower in the Atco range. All three models – 20", 24" and 30" – were largely hand-built by a small team.

Rotary mowers

Atco in more recent years have been producing rotary mowers powered by either petrol or electricity. Production of petrol-engined cylinder mowers continues with the "Clipper" range, in three sizes.
