Here is a YouTube video clip of my B1-6 with front mounted sickle bar mower cutting a small field of alfalfa. Attached are some photos of the sickle bar as configured in the clip.

Very nice! What kind of engine is that?

Looks like it does a very nice job. Looks awesome! Thanks for the video and pictures.

The engine is a two-stroke based on the SIMAR rototiller design and is rated at 5 hp. It was made by Bell Aircraft for Frazer based on the SIMAR design.
The B1-6 with the sickle bar is a lot to handle. It is very front heavy and this one does not have reverse which makes it a beast to turn around at the ends. Originally it was designed to have the cutter bar centered. In this position, if the grass has any kind of height to it, the grass bunches up in front of the starter housing. They made another one, I assume later, that has a 8" spacer between the mount and cutter bar giving the grass more space to pass by the mower frame. I don't know if the previous owner made this mod or if it was a factory fix. It works OK as long as you don't take a full cut. The other thing that could be better is the engine speed compared to the cutter speed. You cannot go much above an idle or it shakes like crazy. probably would shake itself apart.

Shaking is the number one problem with this type of unit. Most of the ones I have just about kill your arms after a while. About the only good running one is the Simplicity units. You might want to make a shield to mount up front to guide the material off. I believe I had a bolens here that used an aluminum bar in the center. The DB mower used a mowing steel rod in front, and had a kit of rod, they called the high weed rod, to make the stuff go off to the side. I can see with my Pond that the center cutting would bunch up, but they did at least put a cover over the pulley to deflex some of it.
nice to see this machine working, looks like it does a good job of cutting evenly.

Some Bolens sicklebar attachments had a counterweight added to the drive mechanism to reduce some of the shaking.
Most sicklebars that I have seen do not have any anything to counter-balance the reciprocating mass.
Obviously, a longer bar, with increased mass, will shake more than a shorter bar with less mass.

Well, it is fun playing with this old iron, I am just glad I don't have to use it on a regular basis. I always like to try all the attachments for the different model ROTOTILLER pieces that I have. Next on the list is the Buck Saw for the one-wheeled Roto-ette Home Gardener. I got a NOS unit that is still wired together as it came from the factory.

Thank you and your son for having a forum like this to post the stuff we like to play with. It was good to see you and yours son as well. That is a nice show for the two and four wheeled garden tractors.
