Masport 300 ST 3'n1 Lawn Mower

The Masport 300 ST 3'n1 Lawn Mower delivers powerful, versatile performance for everyday lawn care. Powered by a Masport Series SEVEN IC 159cc OHV Auto Choke 4-stroke engine, this capable petrol mower combines easy starting, strong performance and durable construction to make light work of maintaining your lawn.

Built around a 460mm (18") heavy-duty steel chassis, the Masport 300 ST features a cast iron cylinder sleeve for added engine durability and Masport's proven Quadcut® 4 Blade Disc System for excellent cutting and catching performance. Increased airflow generated by the four-blade cutting system helps efficiently move grass clippings into the catcher for a clean, well-groomed lawn finish.

With three mowing options – catch, mulch or rear discharge – the Masport 300 ST can be easily adapted to different grass conditions and lawn-care preferences. A generous 50 litre high-density plastic catcher, single-point cutting height adjustment and 10 cutting positions from 10mm to 70mm make it a practical and versatile choice for Australian homeowners.

Masport Series SEVEN IC 159cc Engine

The Masport 300 ST is powered by a Masport Series SEVEN IC 159cc OHV 4-stroke engine, producing a rated torque of 6.3ft/lb or 8.5Nm. Auto Choke technology provides convenient starting whether the engine is hot or cold, while the cast iron cylinder sleeve provides additional durability.

Catch, Mulch or Rear Discharge

The versatile 3'n1 mowing system gives you three different ways to manage grass clippings. Catch clippings for a clean and tidy lawn, mulch finely cut grass back into the lawn to naturally recycle nutrients, or use rear discharge when collection isn't required.

Masport Quadcut® 4 Blade Disc System

Masport's proven Quadcut® 4 Blade Disc System uses four cutting blades to deliver efficient mowing performance. Increased airflow beneath the mower deck provides excellent catching performance by helping move grass clippings efficiently into the catcher.

Mulching Capable

The mulching system recuts grass clippings into finer pieces before returning them to your lawn, helping naturally recycle valuable nutrients and organic material back into the grass.

50 Litre HDPE Catcher

The large 50 litre high-density plastic catcher provides generous capacity for residential mowing while offering a durable and practical solution for grass collection.

Catcher Full Indicator

An integrated catcher full indicator shows when the catcher needs emptying, removing the guesswork and helping you mow more efficiently.

Zone Start

The conveniently positioned Zone Start starter cord reduces the need to bend all the way down to the engine when starting your mower, providing a more comfortable starting position.

Rear Discharge Chute

When you're mowing without the catcher, the dedicated rear discharge chute is designed to efficiently release and distribute grass behind the mower while helping minimise blockages.
