mort 24 #1 Posted July 9, 2023 Is the only PTO stop for the handle just this little bracket shown in the picture below? I have two 418-A and both PTO handles are not at 12 o'clock like my 310-8 is. They are more like 10-11 o'clock and having difficulty with the PTO safety switch for starting. I have a 518-A that has a heavy duty bracket that stops the PTO handle from going past 12 o'clock. Very nice design!!! I did straighten this bracket out and put in spring #103125 shown below but still not at 12 o'clock. Has anybody re-designed this bracket to make the PTO handle return to 12 o'clock? Do al Wheel Horse tractors have this #103125 spring for the PTO handle?

Jon Paulsen 290 #2 Posted July 9, 2023 (edited) My 416-8 takes stop part number 112415 according to the IPL for years 1993 and 1995. Spring number is as you noted (I only checked 1993, probably the same for similar models of similar years). If it is fully engaging and disengaging, why does the angle of the handle matter? The position of the stop could be determined on where there is space to mount it securely. Maybe look at pictures of the same model and see what the PTO lever looks like. You should download the IPL's for your tractors if you haven't already. Picture's worth lotsa words Edit: Had a look at some pictures of various models. Looks like the PTO lever on some resides in the tunnel between the feet. I could see position being a problem there. I did note several models similar to mine allow the handle to roll back well past 12 O'clock when disengaged. Have a look at the photo section for your model in question here: https://www.wheelhorseforum.com/forum/17-wheel-horse-picture-gallery/ Edited July 9, 2023 by Jon Paulsen Share this post Link to post Share on other sites
peter lena 8,714 #3 Posted July 9, 2023 @mort done a lot of functional detailing on w/h lever linkage points , typically sloppy with actual movement engagement . would also look at every stage of start / finish stroke.whats stopping you from backing up, adjusting that stop point ? also note other change to , lever trunnion to heim joint , lever pull in start point , with all the added washers, battery tender plug in point , engine grounding added cable to battery ground bolt point , pete Share this post Link to post Share on other sites

mort 24 #5 Posted July 9, 2023 Thanks all! yes that is #112415 in my picture that the original owner bent like that. No I don't care about the position of the lever but I thought my other Wheel Horse tractors were at 12 o'clock Like I said I am having to wiggle the PTO lever to get it to start. Not the proper way to start it. Trying to fix it so I can move on. The main issue I am having with this automatic transmission is the neutral position adjustment needed. I bought it this way and never had a chance to adjust it and I have never done it before. Mort 1 Share this post Link to post Share on other sites
Jon Paulsen 290 #6 Posted July 9, 2023 Gotcha bro. mort. Wish I could help with the transmission, but mine are both manual gear boxes. I should point out I am very new to these tractors, so if someone gives a conflicting answer, take it Good luck getter her how you like. Share this post Link to post Share on other sites
mort 24 #7 Posted July 24, 2023 Making some progress but still having some issues on my 418-A. Still need to wiggle PTO handle to get is to start and the PTO is not engaging at all. I do have other Wheel Horses so I know the procedure. To engage the PTO is it strictly mechanical or is it electrical too? Does the PTO switch just for starting or is there another position for the PTO to engage? I can change the switch if it will help both situations.. 418A will run in forward and backward but mid mount hydraulic lift not working at all. What are possible fixes? Thanks, Mort Share this post Link to post Share on other sites

Thanks, Mort The PTO has both mechanical and electrical functions. Mechanical is the rod that tightens the PTO clutch and to engage it. Electrical is two switches inside the hoodstand that: a) prevent the engine from starting while the PTO is engaged, and b) stop the engine if the operator leaves the seat while the PTO is engaged. The PTO lever usually pivots on plastic bushings. If they are worn/gone it’s possible the lever is not pressing enough on the switches to register that it is in the disengaged position. It’s also possible that one or both of the switches need replacement or even that the wiring connection to the switches has become contaminated/corroded. The two switches are “ganged” together with small screws and nuts that also hold them to their support bracket. To get at these for a closer look, you’ll need to raise the hood and remove the battery. The switches and the wiring connector are pretty standard and available from vendors here on the forum.

peter lena 8,714 #9 Posted July 24, 2023 @mort my lever stop in first reference photo , is straight down to hold lever stop as its saposed to work , question, is ther complete solid / smooth motion to that lever ? as I set mine up , ensured every related movement point / intended function , was very easy . another thing I did was to look at in use, had a linkage drag on cowl siding , slight bend , eliminated that , also lubed that spring mount , to enhance lever stroke . often just look for problem spot , probably hiding in plane sight . pete Share this post Link to post Share on other sites

Lee1977 6,773 #12 Posted July 25, 2023 (edited) Stright up PTo lever ios not normal all mine lean back around 15 degrees. It's a type of cam action to keep it from falling forward when you hit a bump. All mine have stops at that angle the battery plate mounting tab is the stop on my 312-8. The 520 being wider there has a stop bolted at the same tab on the battery plate.. Edited July 25, 2023 by Lee1977 Share this post Link to post Share on other sites
