The AS 63 4T B&S is the light, controlled Allmäher in the AS-Motor line-up, built for users who need strong cutting performance without the weight of a larger rough cutter. Its 61 cm deck and cross-blade system clear long grass cleanly, and the self-braking transmission gives you steady downhill control, which is a major advantage on orchard banks, ditch edges and uneven slopes.
It suits smallholders, councils and contractors who want a machine that feels predictable in awkward areas. The low weight makes it easier to hold on a slope, and the permanently locked differential helps the wheels stay planted on softe
What the AS 63 4T B&S Is Built For
The AS 63 4T B&S is designed for users who need a safe, predictable machine for long grass, orchard work and sloped areas where heavier rough cutters feel unwieldy. Its light weight, self-braking transmission and cross-blade system make it ideal for grass that grows tall through the season but doesn’t contain heavy brush or saplings. This is the tool you take to banks, awkward edges and orchard rows where precise control matters more than raw force.
Strengths in Real Use
- Self-braking gearbox holds the machine at a steady pace downhill, even on steep runs.
- Cross-blade layout cuts and shreds in one pass, giving tidy results in meadow grass.
- 74 kg weight makes it manageable on slopes and around trees.
- Locked differential gives consistent traction when the ground softens.
- Vibration damping makes longer sessions easier on the hands.
Who the Machine Suits
This model fits smallholders, private orchard owners, councils and contractors who regularly cut orchard belts, meadow strips, access banks and uneven ground. If your work mixes slopes, tighter spaces and long grass, this is the Allmäher that balances safety, manoeuvrability and cutting performance.
Where It Sits in the AS Range
It sits below the AS 65 and AS 73 in raw cutting capacity but above entry-level models in control, safety and stability. Compared with the 2-stroke AS 63, the 4-stroke version trades extreme slope capability for simpler operation and easier starting.
Practical Considerations
- The narrow deck helps it slip between trees and along fencing.
- Reduction drive protects the operator by preventing downhill drift.
- Foldable handlebar makes storage and transport straightforward.
- Rear discharge keeps debris away from the operator without throwing material too far.
If your ground is mainly grass and uneven terrain rather than heavy scrub, the AS 63 4T B&S is the right balance of control, safety and cutting ability.
How Suffolk Mowers Supports Your Purchase
Suffolk Mowers supplies the AS 63 4T B&S fully assembled and test-run, with the drive system, blade clutch and safety interlocks checked before handover. Because this model is often used on awkward banks and around trees, we make sure the variator drive, downhill braking and limited-slip differential are all working exactly as they should.
We keep genuine AS-Motor parts, blades and service items in stock, and our workshop handles routine servicing, repairs and pre-season checks for private owners and contractor fleets. If you’re unsure whether the AS 63 is the right machine for your mix of slopes and meadow grass, we’ll talk through your ground and guide you toward the most suitable setup. Our focus is straightforward: keep the machine reliable, safe and cutting cleanly through the full season.
