Older sickle mower on 700 series AC

Recommended Posts

Well I finally had some time today to mess around with my sickle mower. Here are pics of the FDT PTO on the RBT, I think this was Smilin Sam's or Rod's idea I stole. Biggie Rat did something but I couldn't ever figure out what he did from his posts a while back:


To get the RBT idler pulleys off without taking the tire off, I just unbolt both pulleys off and the it slides right out. You also have to take out one bolt that is a pivot for the cone clutch. Here is the pulley I had to take off the shaft and turn around, and also added 3 thick 7/8" washers. The idler I had to add a longer bolt, 3/8" x 2 1/2", and a stack of washers. I used some random spring I found in my garage for the idler tension. And you can see the part number of the belt I used, it is fairly tight:


Here is a pic from the other side:


These are just the sickle pulleys I guess:


Here is the lift cable, I don't really like the angle it is at, but at least it sort of works. It rubs instead of running cleanly on the pulley, so I gobbed a bunch of gun grease on it as you can see. Good thing that running board was there too to support the chain!:


This is the biggest, baddest filter I could find to screw onto the remote Sundstrand mount, it took right at 4 quarts to fill the hydrostat instead of 3, Baldwin BT 238:


This is the John Holcomb hitch I painted up a while ago. It was a tight fit on the Sundstrand, I had to tweek it just a little bit to fit:


Well that is enough for now. To get the sickle mower actually to cut, I am going to have to remove all the rivets and re-install the knives onto a new knife bar I have, because the old one is broken into three pieces. The sickle mower came from a nice member in NC and rode all the way here in the bottom of a center dump semi trailer. The new knife bar was also made by a nice member here. I also want to replace the 3 heim joints. 2 have to be replaced and I will do the other one too so it is nice and tight. I am convincing myself anyway that if these joints are too loose, they let the bar slam back and forth at the ends of travel contributing to a more early failure.

A short update on this since I have the camera hooked up. The spring for the PTO idler is not strong enough, I only got about 1/2 mile when I used it last, although it could have just been the main belt shredding causing the PTO belt to slip :> The main belt was really old when I started, and a little on the short side, so I need to get a new belt there anyway. Here is the reinforcement on the cutter bar, I just used pieces of the old cutter bar and longer blots and rivets to make it. It also necessitates taking off the outer cutter bar hold-downs to get the cutter bar out. There may also be some worry about adding extra mass to the weight of the bar, but we will see how this goes I guess. I keep the RPM's as low as possible, just above idle seems to be enough for it to run smoothly and cut cleanly and slowly.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
