Titan Pro TP400B/450 Petrol Tiller (3.5HP)
Compact, Lightweight, yet Massively Powerful.
The Titan Pro TP400B/450 is designed specifically for the UK gardener who needs heavy-duty performance in a manageable size. Ideal for turning over vegetable patches, mixing in compost, or preparing new borders, this machine eliminates the back-breaking labour of digging with a spade.
Unlike cheaper 2-stroke alternatives, this tiller is powered by a reliable 3.5HP 4-Stroke Engine, meaning no messy fuel mixing - just clean, consistent torque when you need it most.
Key Features
- 3.5HP 4-Stroke Power: The 156F OHV engine provides high torque at low revs, allowing the tines to bite into stubborn soil without stalling. Runs on standard unleaded petrol (E5 recommended).
- 420mm Tilling Scope: The perfect width for working between rows in an allotment or navigating tight garden borders where larger rotavators cannot fit.
- Adjustable Depth Skid: Control your cultivation depth from shallow weeding (100mm) down to deep aeration (200mm) using the rear depth regulator.
- Heavy-Duty Tines: Features 6 banks of hardened steel tines designed to withstand stones and tough roots without bending.
- Transport Wheel: The front wheel flips down for easy movement to your work area, then flips up and locks out of the way when it's time to till.
- Deadman's Safety Handle: Ensures instant safety - simply let go of the handle and the tines stop spinning immediately while the engine keeps running.
Watch the TP400B making light work of garden soil.

420mm tiller
Having had a titan pro tiller before a 600 I was happy to buy Titan Pro again whilst I miss the grunt and power of the 600 the 420mm tiller is much easier to handle and more controllable. The tiller works well and will bite its way through compacted soils with some patience. Very happy

Garden protector
Very pleased with the machine works well on my allotment. Only draw back to store it when not in use you have to unbolt handle if you need to store in a small space. Collapsible fixings would solve the problem. Supplying company very efficient and I was well informed about delivery.

Petrol Tiller
Machine works very well only criticism is the wheel connection which is designed for cost effectiveness and not for navigation over uneven ground. Hence rating of 4 stars for build quality.A good machine that feels and performs very well.

Rotavator
Delivered very quickly very easy to assemble I filled it with oil and fuel and it started on the first pull of the chord.I like the handle grips - your hands do not slide off when rotavating rough ground. It has plenty of power and will cut up barren land with patience. Very happy
