The engine of this machine requires SAE10w30 oil. The engine will be filled prior to delivery, but subsequent oil changes will require 0.6  litres of oil. We suggest that a first oil change is carried out at roughly 10 hours use, then on an annual basis.

We would also suggest that an annual service is carried out.

The engine is designed to run on standard unleaded fuel, but please be aware that this fuel will go stale very quickly so it is best to use fuel that is less than 60 days old or engine problems can occur.

We recommend the use of ASPEN 4 fuel as it will last indefinitely without going stale, so peak performance and starting is always guaranteed. ASPEN 4 is however more expensive than standard petrol and can be purchased in sealed 5 litre cans from ourselves at the Colaton Raleigh shop.

The S461R PD Instart is a great upgrade from the S461R PD, this model has the addition of an electric push button start 163cc Briggs and Stratton OHV engine.  There's no need to pull on a rope cord to start this mower, simply push the start button

The engine on this self propelled lawnmower, provides drive to the rear roller, as well as the cutting blade, so you don't have to push the mower, making it easy to use, especially on sloping ground.

The wide rear roller, cuts right up to the edge of borders and creates classic stripes, so you'll achieve a beautiful finish to your lawn with ease.

Height of cut varies from 20mm to 70mm, with 5 positions selected using a single lever.  Supplied with a large 55 litre grass collector, which has an indicator to show when it requires emptying, the S461R PD/ES also features ball bearings, and a deck wash link to facilitate cleaning after use.

A 46cm/18" cutting width makes this mower suitable for lawns up to 40m x 40m.
