Thanks to its enormous compaction force combined with a quick forward and return travel, the DPU 6555 offers an extremely high level of productivity. It is a very versatile machine for all construction sites where extreme demands are placed on the performance efficiency. In addition, it offers excellent characteristics in terms of service life and operating comfort. Optimal application areas are the compaction of frost coverings and bearing layers in street, path and parking lot construction as well as backfilling buildings. Thanks to a frequency of 69 Hz, the DPU 6555 is universally applicable and even reliably compacts heavy interlocking paving stones. 
Please be cautious with many online dealers that have yet to raise their Wacker prices for 2023 and an effective 6% surcharge from the mfg, this in combination with that  most are not upfront with a customer about the long lead times for an order to ship direct from the mfg, see Patriot’s two Ship from Options.

  • The innovative guide handle provides for very low hand-arm vibrations and optimizes the user-friendliness.
  • An operator present system prevents the operator from being trapped between the unit and an object when working backward.
  • Extensive comfort functions, such as low oil shutdown, self-adjusting V-belts, maintenance-free alternator.
  • A large dimensioned diesel engine offers high power reserves and ensures for a high level of efficiency and long service life.
  • Compatec: Easy to read display of the relative compaction progress. Warning for overload and overcompaction. Brightness adjustment of the lights to the ambient light. Extremely robust and reliable.
Hand Arm Vibration

Lowest hand-arm vibration

The totally redesigned Wacker Neuson guide handle provides a hand-arm vibration of under 2,5 m/s².

This allows for an all-day continuous operation without impairment and risk to the user.

All documentation requirements are omitted if an operator only works with equipment that has acceleration values below 2.5 m/s².

Absorbing Handle

Intuitive guide handle design

Change the direction of travel and control speed simply by moving the handle forwards and backwards.

Electric Start

Available with crank handle or electric starter.

The electric starter model is conveniently started with an ignition key.

A loud signal tone prevents inadvertent draining of the battery.

Pinpoint compaction
Compatec compaction control shows you when the soil is adequately compacted. Over compaction and overload can be avoided.
Easy to transport
On job sites as well as on transportation vehicles: thoughtful details make the transport of our Vibratory Plates comfortable and easy.
Low hand-arm vibration
Especially in continuous use low hand-arm vibrations (HAV) are essential. Our reversible vibratory plates can be used without any time limit and mostly even without documentation requirements.
User comfort installed
For particular user friendliness all Wacker Neuson models are easy and simple to use.


UPDATE – In Patriot physical stock, but see shipping priced options below as Wacker has increased effective Oct to a 6% surcharge plus 4% freight (included in our prices posted). Please call for availability as we also stock 5 compaction mfgs at Patriot Equip. 
Price posted is based on a prepaid wire transfer to keep the customer’s cost down, but credit card options at an additional cost of 3% to cover these fees is available at checkout. Bank wiring info will be provided and a business check is welcomed at the same lower price, but will take 2 wks to fully clear prior to any shipping.

About Shipping Options

Unlike the majority of our competitors we stock a lot of the equipment we sell and will provide two price options:

1) Ship from Manufacturer – to compete with other online dealers to drop ship from the mfg, this price is obviously lower with only shipping one time but will be subject to any lead time from the mfg – new orders estimated to ship from the mfg in 6-7 mths (be cautious of others stating 3-5 wks or “usually ships” type of wording)

2) Ship from Patriot – to ship a 2nd time from Patriot stock and will ship at actual freight. Orders by Noon ship same day (based on timing of payment)

We always welcome phone calls to double check the mfg’s lead time and or quicker shipping options from Patriot’s stock.
