    Nice work. Looks very useful. I can’t see the connection between the mowers output shaft and the drive shaft… Did you end up speeding up the speed of rotation? Any idea what rpm the shaft runs at? Is it easy to get the mechanism going from a dead stop (any tire skidding)?

    great looking job. could you take a couple pictures without the guards for us?

    p.s. had to rake and bale a wagon load of straw today, trying to beat the hurricane. fifth day of ninety degree weather. ouch.

    Hi Andy and Mitch, Yes, I will take some pictures with out the guards. I knew I should before I put them on, but you know how hard it is to stop.

    My gear ratios ended up a fair bit different than the ones I got from Mitch, but his cart is built on a #9 (High Gear?). By my calculations Mitches cart would hit 540 rpm on the PTO shaft at about 4 1/2 mph. I decided I wanted it to go faster, 540 rpms on the PTO at about 3 1/2 mph. Realize of course that I have only used it once, but I liked the way it fired up and worked at a variety of horse walking paces. Up hill, down hill, etc. I did stall it out on a dead furrow. But then I stall all my rakes and baler on those **** dead furrows.

    I have a 12 tooth sprocket on the flywheel side and 24 teeth on the PTO side. For the price of a gear and a hub it would be pretty easy to change. Andy, you can give this baby a nod in your workshop with Mark if you like. It will be there. D

    Great idea.

    Do you think you could run a square baler off of it on level ground?

    I don’t think it will run a baler, at least not very well. Wouldn’t be hard to find out, though. I think it would need to be heavier, and need more horses to pull it.

    Don,
    Good going. I wish you weren’t tied up elsewhere during the Innovation Workshop, we will definitely be “nodding at” this rig if it is there. Thanks.

    Do you find that the 3 horse/mule hitch is the right size for raking/tedding?

    Hi Mark, I am quite unsure about 3 horses versus 2. I set it up for three even though I was tempted to build a tongue that could flip around for two or three. I am sure two horses could pull it. I think I might be just as happy with the three when I can ted for a couple hours and have the horses fresh for a little mowing or baling. Mark Kimball says he is tedding all day long with the I & J and two horses. Three is plenty and four would need a heavier cart to do heavier tasks.

    Here are a few more pictures of the cart. I am disassembling it a little to paint it. One thing that is hard to see from the pictures is that the metal plate for the pillow blocks is leveled with the drive line out of the gear box. That is quite a different angle than the tool box, which is parallel with the tongue angle. You have to jack up the back end of the plate to level it.

    Donn:

    Nice work. How much time and $ do you have in this project? Anything you would do differently? Any reason you used a #7 as opposed to a #9? I would like to purchase a more modern tedder but don’t want to use my tractor to run it. This may be the answer.

    I spent about 500$, not including the mowers. I used two broken mowers to start with. I haven’t really looked at the receipt real closely, but that includes parts and labor. The labor I paid for was to knock the flywheel off, weld the gears to the hubs, cut a shaft and weld the pto spline to it. He also cut a key slot in the shaft to place the large gear on. Parts were steel plate, steel for a frame and tow hitch, tin for the covers, two blocks and barings, gears with hubs, and chain.

    Given all the help I had (thanks Mitch), I didn’t think it was all that hard to make or all that time consuming. Maybe 16 hours, and that is because I am a slow welder. After I figured all the parts I wanted and ordered that, I used the time while I was waiting to fit a piece of plywood were the steel plate would go and figured out the shape and bolt holes and perfectly level. I still have time left to paint it and that is rare for me.

    George, will we see you at NEAPFD? Could you bring a couple of guards from the easy cut system just so we could show them. Jay and I are doing a workshop on mower tune up.

    thanks for the info. Yes, we will be at the field days. I’ll bring some guard and some knives.

    I just remembered I was bringing a cutter bar for you. I better put that on a ‘to go’ pile.

    Donn and Mitch I am in the proccess of converting a mower into a pto hitch cart.. only prob is it is a left hand cut and as a result the output shaft goes ant clockwise. I think i have sussed it by taking an old truck gearbox to bits and plan to use the gears from it so a small one meshes with a larger one and turns it the right way… Question is.. can i weld those gears ?? and have i worked this out right… A mile is 1760 yds so at 3 and a half miles an hour thats 6160yds.. or 18,480ft..divide by 60= 308ft/min…. my mower output shaft turns 28 times/ turn of the land wheel.. land wheel is 8ft all the way round.. so..308ft divided by 8ft= 38.5 turns of the land wheel per minute.. that means the output shaft is doing 1,078 revs/min.. so i recon a 20 tooth gear driving a 40 tooth gear should give 540 or near enough.. I will post the usual fotos when i get it done…
