Welcome to Bison Engineering ....

Bison - Not Just Engineering.

Bison Engineering has been making crop rollers for more than 25 years.

Located in Western Victoria, Australia, on the busy Princes Highway / Henty Highways intersection between Mount Gambier and Warrnambool, Heywood is some 350 kms west from Melbourne. Heywood services the local agricultural, pastoral and timber industries.

Bison Engineering specialises in crop rollers.

Bison crop rollers  feature solid rubber tyre expertly machined to within 5mm of each other. Fitting them loosely together on a central drum, allows the tyres to move up and down independently, and thus follow the contours of the ground

Rolling crops greatly increases seed soil contact and a much higher percentage of germination is possible.
