Trailed Gang Mowers - History and Considerations

Since the early 1900s cylinder mowing with simple land wheel driven gang mowers has been the preferred system for generations of groundsman, greenkeeper and park keeper. The low power requirement, simple configuration and ease of adjustment and maintenance make this traditional system a very effective method of cutting and recycling grass.

The professional models today are of two basic cutting widths and may use an 8” or 10” cylinder diameter. Generally an 8” cylinder would be suitable for sport, fine lawn and parkland with a 10” diameter for more growth such as golf course semi-rough or country park and paddock.

Considerations to the suitability of cutting surfaces should be made as gang mowers are designed to work on good level ground and even rolling surfaces. The overall unit weight is also important to maintain traction as the wheels need to remain in contact with the surface to drive the cutting cylinder.

Buyer beware - Lightweight imported “Mini Gang” sets will be useless if you expect a consistent quality of cut - once you move forward and increase speed they start lifting and bouncing leaving uncut ribs on the surface. Unlike a quality professional unit such as the Dennis Guildfords - With each unit weighing 50kg on its own without the towing frame these gang mowers are more than adequate and produce a 1st class result - they are stout enough to hold tight to the surface and remain so even at max cutting speed.

Dennis Guildford Gang Mowers

The 24" (61cm) cut Dennis Guildford Junior gang mower is ideal for lawn, park and sport areas and is the only choice for lower powered towing units - such as ATV, Tractor and Ride on mowers - a minimum of 13hp is required for a set of three gangs. Used correctly and at sensible mowing speed this set up will save hours over modern rotary cut and collect systems.

Single units can also be purchased to add on or enable upgrades to a set of 5 or for a very simple single unit application.

Overall cutting width for a set of three is 69" (1750mm)
