This is one mower I would definitely include in a rally. There is very little information about these incredible mowers. Like the Zephyr the De Luxe was primarily used on bowling greens and other fine turf surfaces. This is also mentioned on the scraper plate. Whilst the Zephyr was made during the 1950s and 60s the SM Deluxe dates from the 1920' / 30's. I have used this mower and the old timer can show these youngsters a thing or two about lawn finishes !
