Durabilt does make some carts and the use Rossi & Sitrex rakes. Most all the V-Rakes work out there but it's knowing how to adjust them to the crop is the key. We trade for many different type or used rakes and the owners say they do not work correctly. We find out most of the rakes were assembled wrong or the rake was set improperly to match the hay's condition. The #1 problem with a wheel rake is traveling too slow 6-10 mph is where a wheel rake performs best.
