Rod and the joys of shuttle shift

Recommended Posts

rsnik
Hello Rod, In a previous post you described the shuttle shift Baron in a positive way, not quite up to solving world hunger, defanging socialism and disarming North Korea, but still pretty darned good. You, the foremost statesman and senator of the marque mow your lawn, you claim, with a Baron S. When the opportunity presented itself I bought one, of course. Now I find there is this annoying little bolt at the end of the shuttle shift mechanism that has a little brake pad on the end that stops the planetary drive so your gears don't grind and you can back up without this screeching noise. I went to all the shops that claim to sell Simplicity parts (they quickly refer you to another shop) and I am without. So I figure, since you mow your lawn with a shuttle shift you must go through these little bolts with a brake pad on the end alot. You might, ideally, have a pocket full of them or at least know where the heck to get one. Best, rsnik

I'm not Rod, but I think I can help.:) I bought one of those brake pads for my 712S from Sandy Lake Implement. I believe the part number is 174854. I assume it would be the same for the slightly older 3414. By the way I suspect the shuttle transmission is great when totally in perfect adjustment, and a pain any other time. Mine seems to badly slip the inner belt, which I plan to replace over the winter, maybe that will make it better. This may be one case where a genuine simplicity belt may be the only option.

Thank you for your kind reply GW. Yes, I went through the manuals and came up with the same part number. I just need a vendor which that part number computes with who has one (if he has 100 us shuttlers should buy all). Best, rsnik.

Any Simplicity dealer that doesn't have the part should be able to order it and have it to you within a week. If they say they can't then they just don't want to be troubled. I'd find a better dealer. I just recently bought four from my local dealer. He had to order them on Monday and I had them by Friday of the same week. I know you can get them from several of our site sponsors.

I just looked them up on Jacks and it shows the number superceeds to 2174854..maybe thats why the dealer couldn't find them..They list for $10.54..I would take the new number to the dealer and see if that works..

rsnik, My shuttle works fine (and it is not a Baron, it is an AC713S) and I have not even paid any attention to that bolt. If you are constantly wearing out that bolt, then something must be out of adjustment. As far as shifting goes, My whole lawn is mowed in 2nd gear. I do not move the gear shift, only the shuttle lever. It is the action of the shuttle when moving the lever between forward-reverse and back that I was talking about. I guess I just have a 2nd gear lawn. I start it with the gear shift in second, lever in neutral and clutch pushed in. Drive out of shed, mow lawn, and back into shed. Not very often that I shift out of second gear when mowing. Guess I better check that pad on mine. Since, as I said before, I have never even messed with that bolt. Just lucky, I guess. Has not been a problem on mine. My tranny was adjusted after I got it. I built that tractor from a pile of parts. The tranny was from a Homelite T13, but the BGB had been removed. I installed a BGB from an AC710 into it, then bolted the assembly into an AC710 frame. After assembly, I adjusted the linkages to make the shift work properly. Worked fine ever since. I was mowing the lawn with my AC716H till I got the shuttle fixed up. That is when I switched the mower over to it. As I said, the forward-reverse shifting is smoother on the shuttle than on the Sunstrand hydro, or at least it is that way on my tractors. One of the best people to talk to about shuttle trannys is Gregc. I think he told me that he has four of them. One other thing. When I post in one of these topics, I am speaking for me, not the club. I am member just like anyone else, and have my opinions and experiences just like everyone else. Being the President of this club does not make me any more of an expert than many of the other members. It just means that, when the last elections came around, I was willing to volunteer some of my time to help keep this place going, and the other members of the club decided that I was the one they wanted to be in the job. By the way, I do enjoy riding that tractor, and it is not a figment of my imagination. Since I built it from a pile of parts from over 8 different machines, it is the best looking tractor that I have. Here is a picture of me getting ready to ride it in the parade at Spring Fling, last April. I hope it looks real in this picture.

Also there are a few other club members who can verify that this tractor does run and shift good, without any squeeling noises.

I had a 3410S and I loved it when I was moving dirt with my Bucket.. (Homemade JB) It was nice to be able to back up and go forward without shifting... The only problem I had with mine was the reverse band and I got one from Jacks and it was good to go...

I have about a 78 AC712S. It does not squeak or squeal when moving between forward and reverse. I mow in 3rd gear at full throttle most of the time. I pushed a lot of snow for two winters in Minnesota and did a lot of between forward and reverse while pushing snow. Guess I don't even know what bolt pad you are talking about?? I have had mine for about 5 years and have not done any adjusting on the shuttle drive system at all. I did replace both belts right after I got it. I do NOT shift gears on the move. I stop and shift with the shuttle lever in neutral and my foot off the clutch. It has no problem moving out from a dead stop in 4th gear. I really have enjoyed this tractor but I guess they can be a nightmare if they get out of adjustment? Have not experienced this so I don't know. Dan aka IronPony

One problem I had was grease would seep out of the planetary gears and get on the belt causing it to slip. Converted to hydro and no more problems. One thing I did like was when plowing a long driveway, and backing up long distances, you had 4 reverse speeds, where as my hydro, it seems to take forever.

The shuttle is only faster in 4th gear reverse. Fourth gear reverse is 1.1 mph faster than a hydrostatic, but 1.9 mph slower in forward. The advantage of the hydro over a shuttle is that to get full speed in reverse all you do is pull hydro lever full back. With a shuttle if you are going forward in second gear you have to put shuttle lever in neutral, (in order not to grind gears) then shift to fourth before before putting shuttle lever in reverse in order to use the faster reverse gear. With the time needed to shift the shuttle between gears the Hydrostatic is faster

Many thanks Mowerman! I entered part # 2174854 and came up with an inflatable companion doll but I realized almost immediately I was at the wrong site. Yep! That is the part at Jack's, called PAD ASMY BRAKE. Ten bucks and change and it is on it's way. That is real good to have that item crossed off the list and I thank you again! Best, rsnik
