AS 420 ProClip 4T Compact Mulching Mower

AS 420 ProClip 4T is the compact member of the ProClip range — a 42 cm mulching mower built for tight, awkward or angled areas where a full-size machine becomes a burden. At roughly 30 kg it’s light enough to swing around obstacles, but still runs the same Briggs & Stratton 850 PXi engine found in the larger ProClip models, so you don’t lose cutting strength.

If you look after small lawns, courtyards, narrow strips or areas with planters and walls, this model clears up quickly without dragging a big mower into places it doesn’t belong. Suffolk Mowers can supply, set up and support it as a standalone mower or as a partner to a 51 cm ProClip on mixed sites.

What This Mower Is Built For

The AS 420 ProClip 4T is designed for the parts of a site that slow bigger mowers down — courtyards, narrow strips, angled beds, tight gateways and any area where a 51 cm deck becomes awkward. Its 42 cm mulching unit and 30 kg weight make it easy to manoeuvre without losing the airflow and cut quality the ProClip range is known for. It’s a tidy-up machine for professionals who want a clean mulched finish in places that normally get strimmed or double-cut.

The galvanised deck and reinforced edge mean it stands up to daily use. It handles maintained turf well and deals with growth up to around 18 cm before you start pushing it into double-cut territory. What makes it work is the balance: the rotated engine layout keeps the weight centred, so the mower feels lighter than it is when you swing it around obstacles.

Where It Works Best

• Courtyards, gardens with tight access and areas with raised beds or walls.
• Small lawns on housing estates or communal spaces.
• Clean-up work after ride-ons or wider walk-behinds.
• Town and estate maintenance where a 51 cm mower is overkill.

Who This Mower Suits

Landscapers, grounds teams and estate gardeners who need a compact mulcher that still behaves like a commercial machine. It’s also a strong choice for private users with more intricate gardens where manoeuvrability matters more than outright cutting width. If you already run a 510 ProClip, this is the natural partner for all the spots the big mower can’t reach efficiently.

Strengths That Matter in Daily Use

• Light handling: at roughly 30 kg it’s quick to turn, reverse and position in tight areas.
• Deep mulching deck: gives a clean, even finish on maintained turf.
• Durable build: galvanised deck and reinforced edges hold up to commercial use.
• Engine protection: triple bearing and friction disc reduce downtime from impacts.
• Reliable B&S 850 PXi power: plenty of torque for a compact chassis.
• Rear-wheel drive: keeps it steady on modest gradients and uneven ground.

Where It Sits in the AS Range

This is the compact option beneath the 51 cm ProClip models. It keeps the same mulching quality but trades speed for manoeuvrability. It’s not a slope machine and not a rough-cut tool — it’s a finishing mower for smaller or more complex spaces. If your work is mainly open areas or longer growth, the 510 models are better suited.

When to Choose a Different Model

• AS 510 ProClip 4T A: for higher output and wider coverage on regular turf.
• AS 510 2T models: for serious slope work.
• AS 510 2in1 versions: for long or wet grass where discharge is useful.
• AS 420 E-ProClip: for quieter operation in noise-sensitive areas.

Useful Accessories

• Operating hour meter: helps plan servicing across a fleet.
• Tilt meter: handy when working on mixed terrain.
