The P5100SPBS lawn mower from Position One Power Equipment is a rear wheel drive, self-propelled mower, powered by the Briggs & Stratton 163cc OHV 4-stroke Euro 2 low emission, low maintenance and extremely economical petrol engine. With a cutting width of 51cm, it is ideal for medium to large size lawns.

The cutting height is easily adjustable to six positions with a single height adjusting lever from 25mm to 75mm.

The engine is easily started thanks to the CDI ignition system and the drive to the large rear wheels is controlled from the rear mounted handle control.

The fully enclosed drive belt can be easily accessed through the new removable maintenance cover. The extra large 60-litre grass collector features a high airflow plastic top with a level indicator to ensure maximum grass pickup and can be easily emptied. After use, the deck can be cleaned underneath by running the machine with the garden hose connected to the deck cleaning connection.

The P5100SPBS includes OPC (Operator Presence Control) technology that ensures the engine will not run if you let go of the handle. For easy storing the handles can fold down over the lawn mower making storage compact, ideal for the garden shed, garage or transporting within a vehicle. The ergonomic soft grip handles can be folded forward to reduce space in storage and transport.

The P5100SPBS comes with a mulching plug, side discharge chute and tools. Fitted with a hard wearing steel deck for extended long life.
