New to the forum... I Recently Purchased an l3901 and looking to add rear wheel spacers either 3 or 4" my FEL is 60" wide and running r4 tires does anyone have experience with either size spacers. I dont want to see tire marks if i backdrag or use implements. If I measure the tire treads i'm pretty sure about the 3's but the 4's are iffy. I have a lot of hills and want to be as stable as possible. I plan on filling the tires after I get the spacers on just so im not dealing with heavy tires to put back on and plan on having the backhoe on most of the time. any advice on experience with either would be appreciated
