AS 510 ProClip 4T A is a professional 51 cm mulching mower built for commercial turf, estates and contractors who cut often and want to stop wasting time emptying grass boxes. It runs a Briggs & Stratton 850 PXi engine with a closed mulching deck that keeps clippings circulating until they’re finely chopped and dropped back into the lawn. The balance is good, the drive is simple, and it’s built to take the knocks that come with day-to-day work.
This version is a straight mulcher. No discharge modes, no collection, no fuss. If your sites are mainly flat or gently rolling and you’re cutting on a sensible schedule, the AS 510 ProClip 4T A is a dependable main mower that covers ground quickly and leaves a tidy finish without the cost or downtime of handling green waste. Suffolk Mowers can supply, set up and support the machine for long-term use.
What This Mower Is Built For
The AS 510 ProClip 4T A is designed for regular contract mowing where clippings need to stay on the ground rather than being hauled away. The 51 cm closed mulching deck chops grass into fine pieces and drops them back into the turf, letting you move steadily without stopping to empty anything. On maintained grass up to roughly 20 cm, it delivers strong output with a predictable finish.
Where It Works Best
- Housing estates, business parks and amenity lawns where weekly or fortnightly cuts keep growth manageable.
- Commercial and domestic sites that don’t justify a collection mower because disposal costs outweigh the benefit.
- Ground with the usual mix of kerbs, tree roots and hidden lumps where the triple crankshaft bearing and friction discs protect the engine.
- Moderate slopes and uneven patches where rear-wheel drive and aggressive tread wheels help keep pace steady.
Who This Mower Suits
Contractors and estates teams who want a dependable main mower for day-to-day work will get the most value here. It also suits gardeners running several small to mid-sized lawns in a route, and high-end domestic users who want professional kit without moving to battery or managing premix fuel.
Strengths That Matter in Daily Use
- Balanced handling: the rotated engine and wedge-shaped front wheels reduce grass flattening and keep steering light.
- Consistent cut quality: the deep deck keeps clippings circulating until they’re properly chopped before dropping back into the turf.
- Engine protection: the third crankshaft bearing and friction discs give insurance against hidden objects.
- Drive flexibility: the variator lets you adjust ground speed mid-cut, useful when shifting between open ground and tighter areas.
- Simple upkeep: familiar 4-stroke servicing, easy access and no battery planning or premix cans.
Where It Sits in the AS Range
This model is the straightforward 4-stroke mulcher in the 510 line. It’s the sensible choice when you want strong output on flat and rolling ground without the need for discharge options or slope-specific engines.
When to Consider a Sibling Model Instead
- AS 510 ProClip 4T A 2in1: if your sites sometimes need rear discharge during first cuts or in wet conditions.
- AS 510 ProClip 2T ES A: if your main work is on banks or ditches where a standard 4-stroke isn’t the right tool.
- AS 510 E-ProClip A: if noise limits or internal policies are pushing you towards battery equipment.
- AS 420 ProClip models: if your work is mainly tight areas where a 51 cm deck becomes awkward.
Useful Accessories
- Operating hour meter: helps plan servicing and track usage across teams.
- Tilt meter: useful for operators working close to the machine’s slope limits.
- 5-litre tank: cuts down on refuelling during longer jobs.
- Front and side guard: extra protection for the front wheels in rougher environments.
