John Deere 42" lawn and garden tractor front blade. Model 42 Blade-LT. Serial number M02691X. Purchased to retrofit to a hydraulic quick-tatch mount but went a different way. John Deere parts book shows it fits LX and GT series lawn tractors and the 320 from 1991-1994. The lift linkage that comes with the blade does not match the parts book. The cutting edge is worn.
