Groundscare and fine turf pros visiting the Ipswich base on 10 and 11 October will see the manufacturing process and a display of kit from the first Budding lawnmower of 1832 to the latest Meteor mini-flail mower.
Marketing manager Gina Putnam said: "As well as the guided tours we’ll hold product demonstrations and there’ll be the opportunity to meet and network with other industry professionals."
A "tented village" will house industry partners including IOG, BIGGA, STRI, GEO, Everiss, Syngenta, GreenTek, Bernhards and others.
The two-day event will also include a BBQ lunch and a "nearest the pin" competition on the 1st hole of the company golf course, she said.
"The aim of the open house is similar to the 2010 event and will provide end users across the sector the opportunity to see the Ransomes Jacobsen operation at first hand."
