Dino i think ya mean Geoff not Geoff. But hey thats ok, i used to be Ge-off in high school.
Anyways, as far as i can remeber Diamond had the first v, i still see them around. Production stopped in 94, when the pull away arrived on the market.
The difference between the diamond v and todays, is the wings sloped up, like a true highway v-plow. Also there was more snow loss between the winges, because the rubber wasn't as good as what is in use today. However the plow weighed way too much, Diamond plows are built tough, their streight blades are the heavest in the industry, however the total weight is less than a comparable fisher. The reason is the diamonds mounting system weighs less than the minute mount, however the actual blade weigh much more.
Diamonds V's production ended with the creation of the pull away, and a change in pump and controll options. The other biggest reason is it was getting to heavy for even a 1 ton front end. I know the diamond v was in production from 1980 or 81 (maybe earlyer) to 1994.
When was the first boss built?
