A robot lawn mower for uneven and steep lawns


Masters slopes and mows large lawns

Yard Force SA900ECO is equipped with good wheels. This gives it good grip even on uneven and steep surfaces. Its robust and stable construction allows it to negotiate gradients up to ± 40 % or 27°. The robot mower is suitable for gardens up to 900 m2.


Yard Force SA 900 ECO works independently

The Yard Force robot grass cutter is particularly easy to operate. Once the robot lawn mower has been installed, it works independently. This also applies to its loading process. If its battery becomes low, it drives into its charging station, recharges itself and then mows again.  


Robot for terrain with slopes

Its compact design and the built-in Li-ion battery (28 V / 2.9 Ah) enable the robot lawn mower to mow uneven as well as steeper areas. The cutting height of the Yard Force SA900 ECO is adjustable. 5 steps between 20 and 60 mm are available. This means that the cutting height can be ideally selected for spring and summer period.


Off-road suitable

With its special wheels, the Yard Force SA900 ECO can easily mow hilly and also steep gardens. The robot mower is able to mow gradients by up to ± 40 %.


Sensors for a safe use

The Yard Force SA900 ECO is equipped with a variety of safety sensors. It has lift, tilt and obstacle sensors. When the robot lawn mower is lifted or tilted, its blades stop within 2 seconds.


Mowing made easy

The robot grass cutter is operated via touch screen. Here you can make certain settings for the Yard Force SA900ECO. Once the robot has been installed and programmed, it works independently and reliably.


Automatic mowing and loading process

The property to be mown must be marked out with a circumferential boundary wire. Settings for the Yard Force SA900ECO can be made from the control panel. The Yard Force 900ECO is by default programmed to operate seven days a week.

Once the mowing time has been determined, the mowing robot works reliably and starts its mowing job daily, at the same time. If its battery becomes weak during mowing, the Yard Force SA 900 ECO visits its charging station. It charges itself automatically and goes on with its mowing process till the mowing program has been finished.


Naturally fertilizes your lawn

The robot grass cutter works with a mulching system. The grass is always shortened a little during the daily work. The fine lawn particles fall to the ground, decompose and serve the lawn as a natural fertilizer and moisturizer.


Mows (not) when it rains

A built-in rain sensor detects precipitation and causes the Yard Force SA900 ECO to interrupt the mowing process. When it rains, it drives into its charging station and waits for better weather. The built-in rain sensor can be switched on or off.

The Yard Force SA900ECO can also mow wet grass. However, this can stick to the blades, the blade disc and the wheels. This can lead to an increased need for maintenance and cleaning. The blades must always be in good condition for a good cutting pattern and good mowing performance!


Maximum safety and easy operation


A safe mowing operation is ensured

The Yard Force 900ECO robot lawn mower is protected with a PIN code and is therefore also protected against theft. If the robot is stolen from your garden, it cannot be started without the security pin.


Built-in tilt, lift and obstacle sensors

Equipped with an effective safety lock, the robot mower reacts immediately with a blade stop when it is raised or tilted. If the robot grass cutter drives against an obstacle, it stops, drives back and moves in another direction.


Easy operation and installation

All important accessory components for installation are included in the scope of delivery. The operation as well as the programming of the robot lawn mower is carried out via the touch screen. Once the appropriate program has been selected, the Yard Force SA 900 ECO works completely independently in your garden.

Good price and seems to be good quality

Customer review posted on 08/06/2019

Very good mower. Bought because of slopes and uneven lawn and it copes very well. Plenty of torque on motor.

Customer review posted on 05/06/2019

bob does what he is suppose to do excellant

Customer review posted on 07/05/2019

Machine seems to be very good, but only been in use for 4 hours. UK plug converter to bulky for external socket, better to have a moulded UK plug

Customer review posted on 16/04/2019

Very happy with this robot mower.
Straightforward to set up the boundaries and he was happily mowing away after a couple of hours.
Managed to set it up for back and front lawns by running the boundary wire between the two and just have to carry the robot to the front and let him run round then carry him back to charge. Not a problem in my opinion.
Edges will still need strimmed which I would have to do with a regular mower anyway.

Customer review posted on 03/03/2019

Looks like an excellent robot mower at least equal to others that I have looked at. Unable to comment on effectiveness yet but appears a very well built machine. Excellent price and guarantee.
Appears simple to set up but will take a little time. I am looking forward to not needing to mow, collect and dump cuttings
