A few years ago, I made a snowplow for my 1978 1614 PK adapted from a Jeep snowplow. At the time I tried to make it just like a factory built PK snowplow so I cut the plow down to 4' 6" . Mistake, I should have left it the full 5' 6". It sits out in the back yard now. I thought I had a picture of it because I was going to put it on Craigs list but I will have to take another I guess.
I have a 5' plow made from a snowplow for a 4 wheeler mounted on a 1958 Economy tractor 1 transmission and a Briggs and Stratton engine. Rear tires are loaded with cast iron weights and chains.
Here's one more I made a few years ago but I never had enough drive way to keep it around. sold it a couple years ago .Cleared the driveway in a couple of passes, where's the fun in that.
