Thank you Kraig and Charlie for the link to the manuals that Charlie has hosted online!
What are the main differences between an IH #2 trailer and an IH #4 trailer? Two differences I see from the manual illustrations are that the #2 trailer has fenders and a somewhat different latching mechanism for the tilting bed, when compared to the IH #4 trailer. Is one (#2 vs. #4) more durable/better than the other? Will both fit and operate well with an IH Cub Cadet 100 Lawn & Garden Tractor, especially when turning (i.e., no interference with rear tractor tires for usual turns)? I have a John Deere Model 80 trailer for my John Deere 318 Lawn & Garden Tractor and it is built stout.
