Kubota - Powering Advance Industrial Sweepers & Scrubbers

August 17, 2022

The engine accounts for around 1/4 the cost of your industrial floor sweeper or floor scrubber. Reliability and longevity of the engine greatly impacts the quality of your machine. Kubota manufactures a truly industrial strength engine that lasts longer and requires less maintenance.

  • No Timing Belt

  • Cast Iron Block & Cast Iron Head

  • Industrial Design

  • LPG, Gasoline & Diesel

Engine Valve Timing Mechanism – Coordination of motion of pistons and valves

  • Internally geared camshaft.

  • Lubricated and protected from dirt and designed for the life of the engine.

  • Higher reliability and uptime.

  • Reduced maintenance.

  • No risk of catastrophic damage to valves due to timing belt failure.

  • Designed to run reliably in tough industrial applications.

Potential for Pistons to Contact Valves – Interference Design

  • Due to internal lubricated camshaft gears have minimal risk of valve train timing failure.

  • Virtually no risk of unplanned and expensive engine down time and repair due to timing issues.

Engine Head and Block Material

  • Cast iron block and head with comparable thermal expansion rates reducing stress on head gaskets and cylinder head bolts.

  • A Kubota design cast iron cylinder head mated to the cast iron cylinder block is better suited to industrial applications for long-term durability. Whereas typical automotive based engine designs are optimized for higher maximum power output, reduced weight, and minimal production cost (aluminum head/cast iron block).

  • Kubota’s use of common materials between the cylinder head and block reduces stresses in the gasketed joints resulting in long-life. This minimizes the likelihood of random head gasket failures and associated downtime in high hour usage applications.

Crankshaft Bearings and Cylinder Block

  • High capacity crankshaft bearings and cylinder block designed for diesel engine loads for long life.

  • Kubota main bearings are more heavy duty in design since they are based on the diesel platform; this provides greater reliability and longer life.

  • More rigid engine structure on engine block (since borrowed from diesel) results in less radiated noise and vibration.

Parts and Service Availability

  • World renowned for their reliability and for their parts and service network when needed.

  • Well established quality reputation and service network to stand behind their products.
