That would be a McCormick Deering tied in with Farmall\International Harvestor, depending on the yeat of the mower it will be red with blue wheels and cutter bar or yellow and red.
The Deering name has nothing to do with John Deere.
Since Deering was the forerunner of John Deere, the colours would be green with yellow lettering (the same as on a John Deere tractor).
