AS 900 Enduro Long-Grass Ride-On Mower

AS 900 Enduro is a tough, straightforward long-grass rider built for meadows, orchard ground and rougher areas where a domestic lawn tractor won’t last. The 656 cc Briggs & Stratton V-twin delivers steady power, while the 90 cm side-discharge deck and pendulum-blade system handle tall, dense growth without clogging.

This model suits private landowners, estates and clubs that need a reliable high-grass machine with long runtime and simple maintenance. Suffolk Mowers supports the AS 900 with practical advice, setup help and aftercare, making it a solid choice for anyone wanting a durable rough-cut rider without stepping into Sherpa pricing.

Built for heavy long-grass work

The AS 900 Enduro is designed for tall, dense growth where a standard garden tractor will stall or clog. The 90 cm side-discharge deck clears material quickly, and the pendulum-mounted blades fold back on impact, reducing downtime if you hit stones, branches or hidden debris. It’s a no-nonsense machine built for land that sees real use, not lawn-level grooming.

What it handles well

This model thrives in meadow grass up to around 1.2 m, mixed rough ground, dam margins, orchard strips and areas close to woodland. It keeps material moving without mulching or recirculating clippings, which is ideal for productivity on large, rough areas.

Where the AS 900 sits in the AS-Motor range

Positioned between domestic garden tractors and the Sherpa models, the AS 900 offers a strong step up in durability and output but without the higher cost of the 915 and 920. It’s a simpler, rugged alternative to a Sherpa for buyers who want dependable performance without advanced features or cross-blade systems.

When buyers step up or down

If you need more manoeuvrability in tight spaces, the AS 915 Sherpa is the better fit. If you regularly deal with denser material or need more drive strength, the AS 920 Sherpa provides a noticeable jump. For steep banking or scrub, users move to the AS 940 or YAK flail ranges. The AS 900 is the workhorse in the middle: strong, reliable and cost-effective.

Who the AS 900 Enduro is for

This machine appeals to buyers who want a straightforward, durable rough-cut rider that can stand up to harsh ground and genuine long-grass work.

Typical users

• Smallholders with paddocks, dam margins and irregular ground
• Fishing clubs and conservation groups maintaining banks and access paths
• Estate teams clearing meadows, woodland edges and orchard strips
• Contractors needing a dependable secondary long-grass machine
• Private landowners wanting something stronger than a domestic tractor

Day-to-day strengths

The AS 900 is focused on strength and reliability. The Briggs twin, the hydrostatic drive and the supplemental cooling all work together to support long sessions on tough ground. The foot-operated diff-lock is simple to use and provides instant traction when needed.

Key advantages in real work

• Reliable power: 656 cc B&S V-twin with fuel and oil pump
• Pendulum blades: fold on impact, protecting the deck and spindles
• Side-discharge deck: keeps material moving in tall growth
• Hydrostatic drive: variable speed up to 10 km/h
• Diff-lock: engaged via foot pedal for slippery or uneven ground
• Continuous operation: traction drive has dedicated cooling
• 15-litre tank: long runtime without refuelling

Comfort and control

The upright seating position and adjustable seat give the operator good visibility and legroom. Steering is light and predictable, which matters when working around trees, ponds or uneven sections. For longer sessions, the optional suspension kit smooths out rough areas.

Operator-focused features

The simple control layout, solenoid blade clutch and clear forward/reverse travel ranges make it easy for different operators to use without a learning curve.

Operational realities

This is a high-grass machine designed for open areas and uneven terrain, not a bank mower. It handles slight slopes comfortably, but it’s not intended for steep gradients or heavy woody scrub. Its strength lies in its ability to keep moving through tall, soft vegetation with minimal strain.

What to expect on different terrain

On flat and gently sloped land, the AS 900 is steady, predictable and quick. On rougher sections, the diff-lock provides enough support to keep you moving, and the bumper and deck design help protect key components from impacts.

Useful accessories

A range of optional extras extend the AS 900’s capability across seasons and terrain types.

Popular additions

• Suspension seat kit: improves comfort on uneven ground
• Trailer and hitch: handy for estate and club work
• Snow blade and chains: adds winter clearance use
• Lawn tyres: for lighter ground without deep tread marks
• Tilt meter: displays slope angle for safe operation
