cafoose 3,456 #1 Posted May 14, 2020 Here is the finished project @WildmanC120 I'm finally finished with converting my GT-14 from electric PTO to manual PTO. It looks like a rig job but it's functional. At some point in the future I may redo the mounting of the bracket. I had to space it out three inches from the hood stand. I had to trim the belt guard a little bit with my angle grinder and get a drive belt that's two inches shorter. It calls for an 85 x 5/8 belt but the pulley I had to use with the PTO is smaller so I went with an 83 x 5/8 belt. I don't notice much if any difference in ground speed. I also fabricated a battery hold down bracket. Here is my previous thread on this project: 3 1 Share this post Link to post Share on other sites
Ed Kennell 42,187 #2 Posted May 14, 2020 I see your bracket does not have the clutch calibration notch between the on/off notches. I thought they all had this. What tractor Is your bracket from? Share this post Link to post Share on other sites

Do you have any laying around? None in stock Chuck, but I am always looking. BTW, nice conversion. IMO, this was WH's best PTO design. No wires, no switches, and no moving parts. 2 1 Share this post Link to post Share on other sites

Thanks Ed that makes me glad I chose that PTO design. I believe it's period correct for my GT-14 too I would still like a calibration bracket though. Share this post Link to post Share on other sites
edgro 680 #6 Posted May 14, 2020 My raider 14 also has the same bracket as shown on the gt14, no center notch 1 Share this post Link to post Share on other sites
RandyLittrell 3,906 #7 Posted May 15, 2020 Anyone know if the Techy's and Kohler's used the same manual PTO? Thanks, Randy Share this post Link to post Share on other sites

Thanks, Randy I'm 99% sure as long as the crankshaft is the same diameter. Which tractors are you working with?

I will do some looking and if nothing else, I will just take them off and measure. Randy Share this post Link to post Share on other sites

I will do some looking and if nothing else, I will just take them off and measure. Randy I think the C-120 would have the later style PTO and I used the earlier style. You would have to fabricate the engagement lever differently from how I did it because of the way it's designed. The later PTO clutch disc is larger than the earlier style. You would have to change the engine pulley because the GT-14 pulley does not have the provision to attach the manual clutch components. The C-120 if it's a hydro the pulley would be fine but if it's a manual the pulley is much smaller which would substantially lower your ground speed. The C-120 hydro pulley would require a belt two inches shorter. The GT-14 uses an 85 x 5/8 belt and you would need an 83 X 5/8 belt. The ground speed would be a little slower with the manual PTO because of the smaller engine pulley but I hardly noticed a difference myself. This manual shows both Techy and Kohler engines available and looks like the PTO components are the same for both notice the later PTO style in the picture: Share this post Link to post Share on other sites
RandyLittrell 3,906 #11 Posted May 15, 2020 @cafoose Thanks for all that info!! Those are some facts I didn't know about the pulley size. I plan on putting in an 8 speed on the GT14 so that will work out just fine and I don't have an issue fabbing things to fit. One of my concerns was whether the shafts were the same but it sounds like they probably were. Thanks! Randy Share this post Link to post Share on other sites
cafoose 3,456 #12 Posted May 15, 2020 You're welcome Randy. I just ran across this post I put in and it lists the parts I used from the Raider which I believe is a manual shift and what I'm seeing is 8hp may have a smaller crankshaft but 10-12-14 are the same referring to different part numbers shown for the 14-54 bearing race. It looks like pretty much everything else is the same and I believe Raiders came with both Techy and Kohler: 1 Share this post Link to post Share on other sites
Ed Kennell 42,187 #13 Posted May 15, 2020 Yeah, my Raider 10 has a HH110 and an 8 speed. 1 Share this post Link to post Share on other sites
WildmanC120 613 #14 Posted May 15, 2020 Nice job. Looks like a pretty straight forward conversion. Would be nice to be able to retain the larger drive pulley though 1 Share this post Link to post Share on other sites
