Product Details
Description
Electric Start Simplicity on a Versatile 17" Mower
A good mower shouldn’t make you work before you’ve even started mowing. The Hyundai HYM17150SPEX takes the effort out of starting with a push-button electric start system. No pulling, no sore shoulders. Just press and go. The recoil backup is there if you need it.
This is a 17" / 43cm self-propelled mower with the 139cc engine that’s proven across the Hyundai range. It handles small to medium gardens with ease, and the 4-in-1 cutting system gives you the flexibility to mulch, bag, rear discharge, or side discharge depending on conditions.
Key Benefits
Button Start, Every Time
The electric start system eliminates pull-starting from your routine. A rechargeable battery and onboard starter motor do the work. Press the button, the engine fires, and you’re mowing. Simple.
Self-Propelled Convenience
Rear-wheel drive moves the mower forward under engine power. You guide the direction; the machine provides the momentum. This makes a real difference over the course of a full mow, especially on reasonably uneven ground.
Four Cutting Modes
Mulch to return nutrients. Bag for a clean finish. Side discharge when grass is long and dry. Rear discharge for quick passes. The HYM17150SPEX adapts to what the lawn needs.
Who Is This For?
Ideal for:
- Owners of small to medium gardens (up to approximately 750m²)
- Those who prefer electric start over recoil starting
- Gardeners wanting a compact self-propelled mower with mulching
- Users with shoulder issues or limited upper body strength
Not ideal for:
- Very small lawns where a simpler hand-push mower would suffice
- Large lawns over 750m² (consider a wider cutting width)
- Those on a tight budget (the recoil-only HYM17150SPX costs less)

Frequently Asked Questions
How does the electric start work?
A rechargeable battery powers an onboard starter motor. Press the start button and the engine turns over automatically. The included charger keeps the battery ready between uses.
What if the electric start battery is flat?
The HYM17150SPEX has a recoil start backup. Pull the cord and the engine starts the traditional way.
Is this mower self-propelled?
Yes. Engage the drive lever and the rear wheels are powered by the engine. You steer; the mower moves forward.
What’s the difference between this and the HYM17150SPX?
The SPEX adds electric start. Both share the same 139cc engine, 43cm cutting width, and 4-in-1 system. The SPEX weighs slightly more due to the starter motor and battery.
What warranty does it come with?
3 year warranty for home users and 1 year commercial warranty.
