616 620 720

620 and 720 are the same machine. Only the decals are different. 616 is less hp (16 rather that 19.5) - uses the Onan CCKA engine rather than the CCKB. Aside from that, all 3 are mechanically the same.

Brian is correct on there being different spindles. Have seen a couple of 620's with the "lighter" front axles.

The axle in the picture is the heavy duty, easy to identify by the heavy arms on top the spindles.

they must have broke a few probley with loaders attachments

what engine is in that 620

we have been repowering with 23hp briggs vangaurd we are dealers for both honda and briggs but the briggs has all of the stub shafts and muffler options that bolt up better for most repowers what did you do for a stubb shaft for the honda flywheel the 616 that i just bought i have a used opposed twin kolher magnam 18 do you guys think it will have enough power

I guess my 620 has the standard front axle. Hope it handles the loader okay..

There's no U joints in the drive shaft...just those fiberglass (not sure what they are made of) discs. Those are tough little discs. Den

Own 4 wheel 20, 2-5015, 5020 and associated equipment and 2 electric forklifts.

I dont know much about any of them except the 616. There were 3 different 616s made. There was the regular style 616 which was the cheapest and the ruff-up tractor, the 616 hydro which was more of a ruff-up tractor but with the luxury of a hydrostatic-drive transmission, and then there was the 616 special which is what i own it was the most luxurious of the bunch and there was around only 1500 made. They had 5 gears and they were all in a straight line it had a 16 horse 2 cylinder briggs and stratton engine and a 42 inch deck. They had parking brake built in with the clutch and an easy locking hood. They were very good tractors and very luxurious.

You are referring to the 600 series lawn tractors. The topic of this post refers to the differences of the bigger compact garden tractors. The 616, 620 and 720 are the ones with 60" mower decks, 3 point hitch, front and optional rear ptos. All of them were hydrostatic, and all of them were equipped with Onan 2 cylinder engines.

Yes, it can be confusing when they made 2 different tractors with the same model number!

Mine has the none-tapered arrangement.
Speaking of steering, my 620 turns tighter to the right than to the
left. Is that a feature or a setup error on my particular machine?
Is it OK to used the split brakes to assist turning?
