Murphy Products Terra XTREME, Compost and Soil
The best in soil and pulverizing equipment

Murphy Products and Lawns

Lawns by Murphy was founded in 1955 by Harry & Anne Murphy. Lawns by Murphy offers a wide variety of bulk and bagged organic soil and compost products ranging from in-house organic compost, to blended topsoil and colored mulch. In addition the Terra XTREME is an efficient mobile soil pulverizer. a truly customizable product, which can be tailored to suit many different uses and industries.




In 1955, Harry & Anne Murphy founded Lawns By Murphy. The Murphys had a dream, and a good deal of entrepreneurial spirit. They began multiple sod farms, tree farms, sand mining operations, plus a bulk materials and bagging operation. In 1982, their daughter, Tami, joined forces with the family business. Through her work, a successful landscape design and enlarged landscape/hardscape construction business was incorporated into the fold. Growth of various industries encouraged a separation of the businesses so, in 1989, Murphy Products was incorporated and moved to our current facilities in the Oklahoma National Stockyards.

We are proud to offer a wide variety of products to our customers. With bulk and bagged products ranging from in-house organic compost, to blended topsoil and colored mulch, our products are always tailored for our clients. Through our growth process, the Murphy Products, Inc. team has been routinely challenged to provide a consistent blended soil product for our customers. With much of the available organic material in Oklahoma being anything but consistent, it became apparent that there was a need for an efficient mobile soil pulverizer. Following multiple attempts at purchasing machinery to fill this void, our team decided that it would be best to design and build our own. Bright minds came together, and the prototype Terra XTREME was invented. This prototype did the job perfectly, and after 40 years is still operational on our yard today.

Flash forward a few decades and the Terra XTREME model line-up represents a bustling manufacturing wing within Murphy Products, Inc. The ever-evolving Terra XTREME models are used in numerous industries around the United States, and are available for international purchase. Our highly experienced team of designers & fabricators continually work to provide state of the art mobile soil pulverizers. We at Murphy Products, Inc., are proud of our efforts and are determined to continue and advance the Terra XTREME model line-up.
