to be honest i havent seen a new one in years oyer 10 id say \. but the guys who used cut our silage had about 5-6 of the them, although the design was way different to that newer version that Sean made me as in pic above.
there is a contractor operating outside Tralee who still uses lees though, but all of them are between 6-12 years old. he dosnt get new anything including tractors just uses everything till it cant go anymore.
the guy i work with had a few lees two years ago. 10 years or so ago they were probably one of the best trailers on the market judging by their popularity but when trailers like kane, herron, redrock etc came along they took over.
id like to see what a modern lee looks like out of interest
