I just bought a sickle bar for my 900 series tractors off ebay.It looks like it is great shape.There is no belt however.I have some questions i could use some help with 1.what size belt does it take? 2.how on earth do you route it? 3.how do you hook up the chain lift? Your help is greatly appreciated.Keith

Keith, If this is the handle-lift unit that hotwheelo3 sold, I don't think it will work on your tractor. The sickle bar that fits the 900s has a totally different drive system (planetary gear) than used on the non-cone clutch tractors. I hope I'm wrong and someone else can help you with this or that you have the right sickle bar and just need the belt size. Darryl

The correct mower for the 900 series is a black painted planetary gear type sickle mower. Should be MFG 1690030 These use two belts PTO Drive belt 66.2" and Mower Drive Belt 44.1" Belt routes frm the PTO same as the mower deck would. If you bought one of the old red or yellow mowers that has two idlers behind a hinged shield you are going to have to buy another old tractor to put it on because theres no way to drive it off a 700 or 900 series tractor. Those only fit the old PTO setup like on the B series tractors from the 60's.

You mean after all of my arguing that RBTs are better, I am going to have to put my sicklebar mower on a FDT just to use it. OH NO!!! LOL My 210 sicklebar will only hook up to my 61 Wards. It is not compatible with my AC 700s or my Simp 7116 as Sam said.

Rod, you can use the old style sickle bar mowers on the 3300 series tractors since they still used the old style PTO on them with the double sheave pulley(large for mower deck, small for sickle bar) off the right end. Simplicity switched to the cone clutch starting with the 3400 series, which is why those and newer tractors use the planetary drive sickle bar mowers...

Thanks Kirk, I was already aware of that fact. Just doing a little stirring in the FDT vs RBT controversy. All my RBTs have cone clutch setups. Don't have any of the transition period tractors, with running boards and the old style PTO setups. I'm just kinda partial to the late 70s Simp 7000/AC 700 series machines. We all have our preferences.

Thanks fellows.Keith

Now that somebody said that it can't be done I think that this is something that I have to try. I have an old bar run on my 3310 and am thinking of seting it up to run on my 7013.

I have been thinking about this. What I plan to try is to use the old style PTO with a large pulley and 2 smaller pulleys on the shaft. It will swing/hang where the idler assembly mounts on the 7000 series tractors. I'm going to make a new shaft with the largest pulley I can fit on the cone clutch end and the smallest pulley I can find for the other end to get the RPM reduction. I think I can get enough RPM reduction for the sickle mower to work reasonably.

I recall someone had put the old style PTO on the newer style tractor, had to remove the left wheel in order to get the cone clutch idler off to switch from one to the other. If you size the pulley driven by the cone clutch properly you should be able to use the OEM double sheave pulley on the right end. One thing to watch out for is that the 3300 series PTO is unique to that tractor. I believe it uses a slightly larger diameter cross shaft than the older ones.

Or you could have bought my 410 AC with the proper sickle bar and tiller![no mower deck though]for prob close to what you paid for the bar alone?,,dunno maybe wrong there though!,,

make sure not to overspeeed the mower. the book says one third throttle in third gear (equal to a fast walk). overspeeding will cause breakage of reciprocating drive parts. voice of experience speaking-have a broken one sitting in my garage. Weedcutter

I keep reading about sickle bar mowers. I have one for my 3310, and think, perhaps wrongly that I can put it on my 7116, Sovereign or 3416 without any modificatins. In fact, one of the reasons I have these tractors is because I think they are all pretty much compatible. I don't quite understand the cone clutch discussion above. I have what I believe is a cone clutch, but both of the pulley's on it are the same size. One for running the mower, or sickle bar mower, in the case of the 3310. And one that is for running attacments in the back, in the case of all three. Porbably I should simply try and attach the sickle bar mower to any of my tractors, and I will, in due course. But it is easier to read about it than to do it. Would anyone discuss the details about doing this?

John, look closely at the depth of the grooves on the clutch. The outside edges should be the same but all the cone clutches I've ever seen have a wider groove on the outer belt so the belt sets deeper in the clutch. This gears the rear attachments down slightly.
