The one on the left is for a 100 series tractor. It's the deluxe seat for the L120-G110, !45-190C, LA130-LA175, and D160-D170.
Well yes there are several 100 series but I thought it would be easy enough to figure out since I listed all the modelsL120-G110, !45-190C, LA130-LA175, and D160-D170. Are not 100 series tractors about 20 years apart. :dunno:
You are right, I'm just used to calling the D's and LA's the 100 series since I have one.Original 100 series like roaddog4_2's from the 1980's don't have letters in front of the model # like the 130 thru 185's
