My reference doesn't cover the Classic models very well. But it would have to be after the stainless models were introduced in the mid 90s. If it's a WSM it has be after 2001. They were discontinued by March 2006. Sorry I couldn't be of more help.
I will admit, I love deer plots.
I love planting... even the garden at home.
What I do not like are high cost farm implements.
I found myself in need of a cultipacker for clover and other small seed - but could not find a decent deal on a small unit.
OK, fine... I will make one!
The materials were very simple... some plastic corrugated sewer drain pipe, some metal, 2 bearings and some concrete and you are in business!
I cut the pipe, in this case, to 46" wide - as I intended to pull this one...
