At P&Pd, we believe the best farm equipment comes from understanding the real challenges dairy farmers face every day. That's why we design and manufacture innovative dairy farming products that improve safety, efficiency and reliability across the farm.

Proudly designed and built in New Zealand, our specialised range includes dairy effluent irrigation equipment, farm hydrants, drag hose clamps, cattle restraining bars and milking shed service platforms—all developed through practical engineering, on-farm testing and years of industry experience.

Every product is designed with durability, efficiency and simplicity in mind, helping farmers improve productivity while supporting better stock welfare and effective effluent management.

Whether you're upgrading your dairy effluent system, improving safety in the milking shed, or looking for dependable dairy farming equipment that stands up to demanding conditions, P&Pd delivers practical engineering solutions developed by people who understand the needs of modern dairy farming.

We’re committed to creating practical solutions that help New Zealand farmers work smarter every day.

ABOUT US

P&Pd  is an acronym  of “Product And Prototype Development”, which is the principle function of KJ Smith Engineering Ltd.

 

History

KJ Smith Engineering Ltd began in 2000, specialising in the design and manufacture of bespoke small to medium size machinery, and in providing practical engineering solutions  to customer needs.  

 

As time went on the business became increasingly involved in the development of cattle handling equipment and equipment connected with farm effluent application. This trend was fueled by the satisfaction gained from successfully applying creative engineering to meet the needs of the farmer,  and the flow down effect this has on  farm stock welfare and the health of the land.

 

The Present and onwards

P&Pd  is the business vehicle by which field experience and perceptions gained over the last few years, combined with patents obtained during this time, are being incorporated into products that  benefit the Kiwi farmer.

Company ethos

  • to not dilute focus by promoting a wide range of products, P&Pd will stick to what it does well and with providing ongoing, long term product support.

  • to create products that meet user requirements by being: cost effective, efficient, user friendly, reliable and without   unnecessary complication.

  • the product-user is the “expert” when using a product.

  • to offer products at realistic prices that reflect the effort expended on: developing, producing and backing up the products.

  • to conduct business relationships that are: friendly, cooperative, ethical and beneficial to all parties.

Products that benefit the farmer

The focus, at present, is with developing a cost effective and non complex effluent reticulation system that begins at the cowshed and finishes at the point of application.

 

Trials are in progress for various parts of the system and these parts will be released to the market as each is thoroughly proven.  Eventually, it is intended that all these parts will form an integrated, cost effective, non-complex, effluent irrigation system.

 

Expressions of interest are welcome. Have a look at the information on this site and see what you think.

Keep dropping in because as products are developed they will be featured.

 

Feel welcome to email with questions or suggestions.

 

Kind regards,
