Spectrum TG51SE 3-in-1 Self-Propelled Petrol Lawnmower

Built to Spectrum’s consistently high standards, and offering quality features throughout, the TG51SE petrol lawnmower is hard to beat when it comes to value for money!

Power – a huge 4.9hp – for the Spectrum TG51SE 3-in-1 Petrol Lawnmower is supplied by a 173cc four-stroke engine with a lithium-battery-powered key starter for effort-free ignition, and OHV technology for emission compliance, vibration and noise reduction, and improved fuel economy.

Not just powerful, the engine is also seriously ‘torquey’, driving the blade through long, damp grass with supreme ease.

The Spectrum TG51SE 3-in-1 Self-Propelled Petrol Lawnmower benefits from self-propulsion, so will prove a sensible buy if your lawn’s on a gradient, or has sections of rough, lumpy grass.

Centralised height of cut adjustment makes what can be a troublesome process with lesser machines an easy one; extra-large-diameter drive wheels provide superior manoeuvrability, especially when working in long grass. Ball-bearing mounts ensure the wheels will continue to roll freely over time.

Supplied with mulch plug, a side-discharge chute and a roomy, 60-litre-capacity collector – all simple to fit and remove – the Spectrum TG51SE 3-in-1 Self-Propelled Petrol Lawnmower is capable of either recycling, side-ejecting or bagging your grass cuttings.

The catcher has a dust and pollen-retaining hard top, is made from textile to save storage space, and features a practical and convenient ‘catcher’ full indicator.

Other attractive attributes on the Spectrum TG51SE include simple camlock folding and adjustment of the comfortable soft-grip handlebar; a practical grassbag carry-handle for easy emptying of the contents; and a deck-wash port for simple sluicing of the undercarriage.

Lithium-ion starter battery – with LED charge-status indicator – and charger – with ‘Charging’ light – both included.

It should be noted that Spectrum pedestrian lawnmowers and ride-on mowers are covered by an extended five-year manufacturer’s warranty for parts*.

* Ts & Cs apply – to maintain a valid warranty, the machine must be serviced annually from year two onwards

Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
