Yes the ground drive gearboxes on rakes are very dependable as long as gearbox contains correct amount of lubricant. IMHO pto/3 pt rakes are more difficult to utilize than towed type but that may just be MEAre the gear boxes on those ground-driven ones generally reliable?
Yeah I had a 3 point PTO driven rolabar rake and couldn't get rid of it fast enough... a pull type will "turn into the corner" as you rake, keeping a consistent corner (more or less). A 3 pt. mounted rake will swing the opposite way in the turn, making the curve in the windrow worse and to the opposite side... and in corners, it makes "bell shaped" corners that make it a big PITA to bale around corners. If you're in a big, flat, straight sided field and pick it up after each pass and turn around, the 3 pt. rake would be okay. If you're baling odd-shaped fields or fields with lots of obstructions you have to dodge around or irregular fields or anything like that, you'll quickly hate the 3 point rake because your windrows will be snaking all over the place. Plus in heavy hay, the 3 point PTO belt drive cover was blocking the basket and ending up causing problems getting the windrow to roll, because too much hay was hitting the shield... in thin hay, no problem, but if you're rolling a bigger windrow to feed a round baler, well, it's a mess. Pull types have the entire basket front wide open so its no problem with them!Yes the ground drive gearboxes on rakes are very dependable as long as gearbox contains correct amount of lubricant.
