Briggs & Stratton Engine 21R6070009H5CC0001

Engine - 21R6070009H5CC0001 - Briggs & Stratton

The Briggs & Stratton 21R607 is a 344cc single-cylinder petrol engine from the 210000 series — a family of OHV vertical crankshaft engines that has powered ride-on mowers and lawn tractors across a wide range of domestic and light commercial machines for many years. Electric start as standard makes this a straightforward drop-in replacement for machines where the original engine has reached the end of its working life. The 1-inch vertical crankshaft is one of the most common configurations used across the ride-on mower market, giving it broad compatibility with equipment from multiple manufacturers.

OHV with Cast-Iron Cylinder Sleeve

The 210000 series engines are built around an overhead valve layout combined with a Dura-Bore cast-iron cylinder sleeve. The OHV configuration positions the valves in the cylinder head rather than the block, improving combustion efficiency and reducing operating temperatures during sustained use. The cast-iron bore lining holds its shape over years of seasonal use far better than an aluminium bore would, maintaining compression and keeping oil consumption in check long after a lesser engine would have started to show wear.

Electric Start

Starting is by electric starter motor. The 210000 series is equipped with a 9-amp charging system that keeps the battery maintained during operation and provides capacity for 12V accessories — electric PTO clutches, lights and dashboard electrics commonly found on ride-on machines.

AVS® Anti-Vibration System

The engine features Briggs & Stratton's patented AVS linear balancing system. On a single-cylinder engine, the firing interval produces a natural vibration pulse with every combustion stroke. The AVS counterbalancing mechanism smooths this out, reducing what the operator absorbs through the seat and controls and slowing the rate of vibration-related wear on the machine's frame and fixings over time.

Fuel Pump

A mechanical fuel pump is fitted, drawing petrol from the machine's remote tank — the standard arrangement on virtually all ride-on mowers and lawn tractors where the fuel tank is mounted away from the carburettor.

Splash Lubrication

Oil circulation on this engine works by splash, with no oil filter. A dipper on the connecting rod distributes oil to the engine's moving parts during operation. This is a proven, straightforward system that keeps the design simple and maintenance requirements low. Oil capacity is approximately 1.42 litres.

Fitment & Compatibility

The vertical crankshaft is 25.4mm (1 inch) in diameter and 80.19mm (3 5/32 inches) in length, with a keyway — a configuration shared across a broad span of ride-on mower and tractor platforms. The 210000 series is widely used as original equipment on machines from Husqvarna, Stiga, Mountfield, MTD and others.
