Key benefits

• 136″ wheel base chassis
• Two speed axle as standard
• Loading sensing hydraulics
• Baffled 360 gallon polyethylene water tank


The Johnston ES351 mechanical sweeper is mated with a Freightliner M2 Class 7 chassis. Combined they make for one of the best looking, hardest working and most reliable machines in the industry.

Its simple single engine design allows for fuel efficiency and easy maintenance.

Utilizing an Allison 3500RDS automatic transmission, a 10,000 lb front axle and a 23,000 lb two-speed (6:17/8:42 ratio) rear axle geared for proper over the road and sweep speeds, the Johnston ES351 is transporting its load quickly and safely.

Large 44” hydraulic-driven, leading arm, digger- type, free floating gutter brooms with in-cab adjustable speed and down pressure to ensure aggressive cleaning of curbs and gutters.

The side brooms feature a heavy duty steel disc, drilled for either four or five segment broom sections. The broom material is tempered steel tines, 26” long.

At the operator’s discretion from the cab, the dual brooms can extend out to achieve a 144” total reach to facilitate cul-de-sac and curve sweeping.

The Johnston ES351 features a 20 gallon hydraulic reservoir supplying oil to a variable displacement hydraulic pump in a load sensing hydraulic system. This system will adjust flow based on hydraulic demand from the sweeping gear so as to maximize efficiency and reduce heat.

All hydraulic valves are equipped with light emitting diodes to signal function and feature manual overrides. All hydraulics are centrally located in their own system locker for ease of access and maintenance.

The Johnston Easy Sweep Mechanical Sweeper features all the necessary warning lamps and buzzers:

• Low hydraulic oil
• Conveyor stall alarm
• Hydraulic oil temperature
• Hydraulic oil filter restriction indicator • Low water alarm
• Hopper up alarm

All wiring is color coded and numbered. All internal and external wiring conforms to IP65 and IP67 standards – waterproof and dustproof.
