The ATCO GT30H is a compact, easy-to-handle lawn tractor designed to provide the convenience of a ride-on mower without the footprint of a larger garden tractor. Its compact dimensions allow it to pass through a 36-inch garden gate, while its capable cutting system makes it suitable for maintaining larger domestic lawns.
A 432cc STIGA ST450 petrol engine provides the power, with the engine driving a fully hydrostatic transmission. The clutchless automatic system allows continuously variable speed control and smooth transitions between forward and reverse, making it particularly useful when manoeuvring around trees, borders and other garden obstacles.
Twin-Blade Rear Collection
The GT30H uses a twin contra-rotating blade cutting deck designed to produce an even finish while efficiently directing grass towards the rear collector.
The cutting height can be adjusted through 7 preset positions from 25mm to 80mm, allowing the mower to be adapted to different grass lengths and mowing conditions.
Grass clippings are collected in a generous 240-litre rear-mounted collector. A buzzer alerts the operator when the collector is approaching capacity, and the grass box can be tipped from the driver’s seat.
Easy Cleaning & Operation
The blades are controlled using an electronic clutch, allowing them to be engaged or disengaged conveniently from the operator’s position.
After mowing, the integrated hose connection on the cutting deck makes cleaning the underside of the deck easier, helping remove accumulated grass and debris.
Comfortable Driving Position
ATCO has designed the GT30H around a comfortable operator station, with light steering, ergonomic controls and a supportive driving position. The compact chassis and hydrostatic drive combine to make the tractor straightforward to control, particularly in gardens with frequent changes of direction.
A mulching plug and tow bar are available as optional extras, providing additional versatility where required.
