FAQ
What is the difference between a ride-on mower and a zero-turn mower?
A traditional ride-on mower uses a steering wheel and is a good all-round choice for larger lawns and open areas. A zero-turn mower uses independent drive controls that allow a much tighter turning radius, making it faster and easier to mow around trees, garden beds and other obstacles.
What size property is suitable for a ride-on mower?
Ride-on mowers are generally worth considering once a lawn becomes too large or time-consuming to maintain comfortably with a push mower. The best machine depends on the area you mow, the terrain, the number of obstacles and how quickly you want to complete the job.
How do I choose the right cutting deck size?
A wider cutting deck can cover large open areas more quickly, while a narrower deck is easier to manoeuvre through gates and around trees, garden beds and tighter spaces. The best deck size is therefore a balance between mowing speed and access around your property.
Can ride-on and zero-turn mowers be used on slopes?
Some ride-on mowers are better suited to sloping or uneven ground than others. The safe operating slope depends on the individual machine, its tyres, weight distribution and the manufacturer's specifications. For properties with significant slopes, choosing a machine specifically suited to the terrain is important.
What maintenance does a ride-on mower need?
Regular maintenance commonly includes checking engine oil, filters, blades, belts, tyres and the cutting deck, as well as following the manufacturer's scheduled servicing requirements. Keeping the deck clean and blades sharp also helps maintain cutting performance and prolong the life of the mower.
Is a hydrostatic transmission worth it on a ride-on mower?
A hydrostatic transmission is a popular choice because it lets you change speed and direction smoothly without manually changing gears. This can make mowing easier around trees, garden beds and other obstacles, where you regularly need to slow down and speed up. For larger properties or frequent mowing, the added convenience and control of hydrostatic drive can be well worth considering.
Should I choose a ride-on mower with mulching, side discharge or a grass catcher?
The best cutting system depends on how you maintain your lawn. Mulching works well when grass is mown regularly, finely chopping the clippings so they return nutrients to the lawn. Side or rear discharge is generally better for longer or heavier grass, while a catcher provides a clean finish when you want the clippings removed. Some ride-on mowers can support more than one of these options.
Will a ride-on mower fit through my gates and into my shed?
Always measure the narrowest gate, pathway, shed door or other access point before choosing a mower. The overall width of the mower can be greater than the advertised cutting width, particularly with discharge chutes or attachments fitted. Also allow enough storage space to comfortably park and access the mower. A slightly narrower machine may be a better choice where access around the property is restricted.
Can I tow a trailer or use other attachments with a ride-on mower?
Many ride-on mowers can accept attachments such as utility trailers, sweepers, spreaders, collectors, rollers and other lawn-care equipment, making the machine useful for more than mowing. Compatibility and towing capacity vary between models, however, so if you plan to use attachments it is worth considering this before choosing your mower and checking the manufacturer's specifications for the particular model.
Why are servicing and spare parts availability important when choosing a ride-on mower?
A ride-on mower is a long-term investment, so access to servicing, replacement blades, belts, filters and other spare parts can be just as important as the initial purchase price. Choosing a recognised brand supported by an established dealer network can make ongoing maintenance and repairs much easier and help keep the mower operating for many years.
