I have a case 811-b tractor serial number 8144026.  It is stuck and would consider it a parts tractor.  It does have the adjustable wide front.  The grill screens and sheetmetal are very descent.  The fenders are not much and are rusty.  The rear rims are no good and we're the power adjust style.  It does have three nice rear case style rear weights on each side.  It does have most of the original style rear seat better than most and does have the eagle hitch style three point. It is also a case-o-matic drive.  Any questions feel free to call 6202726365
