New for 2025! This stylish, practical and hardworking garden tractor is a must for any lawn up to 2 acres. Powered by the mighty Stiga ST550 586cc twin-cylinder engine and rocking a hydrostatic transmission, the 1638H is a superb ride-on lawnmower! With a 98cm cutting width and a treasure trove of features, mowing the lawn has never been this much fun!
Description
The twin-cylinder Stiga engine is a powerhouse and when you pair it with the 98cm twin blade cutting deck and fully hydrostatic transmission, the 1638H becomes an absolute must-have ride-on lawnmower!
A foot pedal controls the speed of the tractor, with smooth hydrostatic transmission. Engage the cutting blades with a flick of a switch, and if your capacious clippings collector reaches maximum capacity, a buzzer will cheer you on to empty it—making mowing a joy!
If emptying the generous 240-litre grass catcher from the comfort of the driver’s seat is just too much effort, why not fit the included mulching plug and mulch instead! Finely cut the clippings and discharge them back onto the lawn as you mow, giving it a nutrient boost. Talk about multitasking!
Visibility is top-notch from the driver’s seat and the fitted anti-scalp wheels guarantee a lawn finish that’ll make your neighbours green with envy!
Keep your cutting game strong by keeping the deck clean and avoid any rust drama. A handy washing link makes post-mow cleanup a breeze!
Add a tow hitch and a whole new world of accessories opens-up making this garden tractor both versatile and durable.
And guess what? You get a 5-year manufacturer’s warranty with this mower (T&C’s apply), along with a battery charger, mulching plug, and tow hitch! It’s like Christmas came early for your garden!
