1  General / Coffee Shop / Re: Lawn mower land speed record on: Today at 01:41:49 PM
   Does anyone know how Dixie Chopper gets by with advertising as "The World's Fastest Lawn Mower"?  There has to be some documentation somewhere, doesn't there?

Respectfully; Rodney Rom; Rom's Reworks; Butler, MO

P.S. I know it isn't a mower, but I hold the unofficial speed record for the Vietnam War-era Navy NC-2 WWII-Jeep-based ground-support equipment generator vehicle at 62 MPH.  This is a unit with the rear axle switched to the front (no steering) and the steering done with 14x4.50-6 rear wheels, one on each corner, forklift style.  The transfer case drives the generators when needed for aircraft support.  Three witnesses: AS(H)3 Bill Weidman from Hatboro, PA; AS(H)3 Kirby Nanna from Barberton, OH; and AS(M)3 Charles Psaila from Queens, NY.  Bill slowed after shifting from 1st to 2nd; Charlie satyed with me through 2nd gear; I overran the 60 MPH speedo in 3rd to the governor's max.  Kirby was the following-vehicle driver.  Location -- Pier Road, between NAS Norfolk (Virginia) and Pier 12 at Norfolk Naval Base.  Summer, 1969.  No roll bar, either...

   No, it isn't.  The link you gave goes to Other Engines - Info on Engines not Listed Above.  This is for engines other than Kohler, Tecumseh, Briggs and Honda/Clone, which are engines that have their own Help sections.  A Fits All section would be for tips that might work on not only Other Engines -- Kawasaki, Onan, etc. -- but also on Kohler, Tecumseh, Briggs and Honda/Clone. The recent "Copper head gaskets" post is a good example of something that would benefit all engines, and if it were put into the Other Engines section, it would be difficult for mainstream-engine users to find.

   If you're concerned about stretching Admin thinner than they already are by adding another section, I'll volunteer to be Moderator for this section.

   Input from the general membership...?

3  General / Coffee Shop / New "Fits All" Engine Help Category? on: October 27, 2014, 04:04:27 PM

   What about starting a new heading in the Engine Help section entitled "Fits All Engines"?  I notice that there are regular posts to the Coffee Shop section that actually have to do with engine help for any engine. This would be a quicker way to find engine help that is not brand-specific.

  Your thoughts?

4  Mower Building / Setup Help / Driveline / Re: Craftsman LT1000 won't shift on: October 23, 2014, 10:35:39 AM

   GrubDigger has the right idea.  Chances are, this mower was parked out in the weather at some point, and water/moisture got inside the case, corroding and rusting the shift mechanism, as well as the shift keys, collar and shaft.  Teardown and cleanup are the only way to see exactly how bad it is.

   Remove the shift-detent screw, spring and ball before removing the cover.

5  Mower Building / Setup Help / Driveline / Murray Transaxles? on: October 23, 2014, 10:23:41 AM

   I am trying to compile a list of the transaxles Murray used in their late-model riders -- mid-engine, rear-engine, standard, or wide-body -- anything from 1997 to now.  When you look one up in the Murray Parts Lists, all they show is "Transaxle, Peerless (or Dana / Spicer) -- For Replacement Parts, see the Central Service Distributor in your area."  So...whenever any of you come across a Murray rider with its original transaxle, please note the Model Number of both the Murray and the transaxle, then let me know.  All input greatly appreciated!

   If you're unsure of the date of the mower, most late-model Murrays used Briggs & Stratton engines, so look at the first two digits of the engine Code Number -- that tells the year-of-manufacture of the engine, and that is usually also the year of the mower.

   You can Reply here, PM me, or if you want to call me directly or email me, my Contact information is in my Profile.  And yes, I am interested in hydrostats as well as gear-drive transaxles.  If I can compile a reasonably complete list, I will Post it here.

   Thanks!  Wink

6  Mower Building / Setup Help / Driveline / Re: Peerless 717 A 4 Speed, 3/8 input shaft! on: October 17, 2014, 01:34:51 PM
Hi guys, picked up a Peerless 717A 4-speed transmission and everything looks good. But one thing worries me... It sports a 3/8 output shaft with threads on the end. Any ideas or tips? I'm thinking it will be okay, but it'll be hard finding a 3.5" Pulley for it!



   Check out Reply #5 on http://www.heymow.com/index.php?topic=29098.0

   Question: The title of your post says it's an input shaft, but in this question, you state that it's an output shaft.  I presume you're looking for the input shaft...?

  The 600s are obsolete transaxles and are getting extremely hard to get parts for.  Why not flip the 820?  Better, heavier-duty, parts-available transaxle.

  Go to your local airport and get some 100 Octane AvGas.  Much better than normal pump Premium (usually 91 Octane) and no need for mixing.  It's in the $4.50-$5.00/gallon range right now, depending on location.  No ethanol, either...

What's the difference between the two besides they want 200 more for the 140c??

Thanks, boxcar

  The 'C' in the 140C probably denotes copper windings, which would explain the $200 price difference. The plain 140 likely has aluminum-wire windings -- lower cost.  Go with copper.

10  General / Coffee Shop / Returning answering-machine phone call messages on: September 25, 2014, 07:32:05 PM

   Do any of you know a David Cass in Coco Plains, Tennessee?  I'm not even sure on the name and spelling, but if you do know someone close to that name and location, please have him get back to me.

   This afternoon, I received a phone call on my shop answering machine, since I was outside the shop at the time the call came in.  When I checked the messages, "David" wanted to know if I still had the differential locker gears for the Peerless 820 transaxle.  I do, and I pride myself on taking care of my customers, as most of you already know, but at the end of the message, "David" said, "You can call me back on this number."  The only problem is -- he didn't tell me what number, and since I don't have CallerID, I don't have any way of getting back to him.

   When leaving an answering-machine message -- to anyone -- make sure to leave your call-back number.  It's a matter of simple phone courtesy.  And if you have to leave a message, speak clearly and distinctly, especially if you are on a cell phone (my phone is a hard-wire landline), as nothing is more frustrating than having to listen to the same message numerous times to try to decode the scratchy and static-filled message in search of a name and number.

11  General / Coffee Shop / Re: briggs model 40 wiring question on: September 23, 2014, 02:22:42 PM

   Go to your local B&S Service Center and have them Sell you a copy of Form MS-0415, Engine/Alternator Replacement Guide.  Very valuable help.

   Then, go to your local boneyard and get a late-model wiring harness off any mower with the carburetor after-fire solenoid. You'll need the part from the instrument panel to the 6-pin engine connector and the carb solenoid -- you won't need any of the interlock-switch or seat-safety wiring.  It wouldn't hurt to get the starter solenoid and its wiring, either, part of which runs off the ignition switch.

   Lastly, get hold of anyone who has purchased a Sears lawn tractor in the last 10 years, and borrow their Repair Parts Manual.  There is an easy-to-follow Wiring Schematic in the front of the Parts Book that shows all the hookups and connections.

   Any business owner will do -- as long as they have a tax-exemption certificate.  It doesn't have to be a mower shop.  Surely someone you know who has access to a tax number would be willing to help?

   "Retail" price on LTH transaxles are in the $600 range.

13  Mower Building / Setup Help / Driveline / Re: Transmission for Senior Design Project (Peerless 820) on: September 22, 2014, 10:55:42 AM
Thanks for the input. As of right now we are planning to run this transaxle.

So multi-person is 8 to 10 pedalers and a driver. With that being said because the driveshaft will have an individual freewheel for each pedaler the input torque will not be equal to the total force of all the pedalers.
   You're most welcome.
   Are you sure you will be able to accomplish this with an end weight of 3,000 lbs.? 

The current plan is to tow this thing in reverse with the rear wheels off the ground for transportation. We will be building a steering lock-in so that we can leave the front axle on the ground and have the transaxle not under any load when being towed.
   Excellent choice for towing, if you are using tapered roller bearings on the front wheel hubs.

Reasonably long service life is honestly probably only a few thousand miles. By taking the static weight load off the axles, and the torsional load of braking off the transmission by running outboard brakes I think this is quite possible.
   I agree.  You may even get more mileage with your planned setup.

Are the gears helical or straight cut? In other words can I reverse drive them? The reason why is, with the current setup I would have to run a 'B' input Peerless 820 which seems to be significantly more difficult to source. With that being said I can run my driveshaft in either direction so if I flip the transaxle and run the input shaft opposite than the standard spinning direction would this cause damage?
   The 820 has straight-cut, heat-treated alloy-steel gears. 
   The only 'B'-Input 820 curently available is the 820-003, which I keep in stock.  However, any 'A'-Input 820 can be converted to a 'B'-Input by replacing the 'A' Cover with a 'B' Cover and reversing the countershaft bevel gear and thrust washers inside.

Lastly, what is the standard direction of input on the 820 'A' and 820 'B'?  Can I run the input shaft in the opposite rotation? Meaning if I flip the transaxle in a way that would usually mean that I would get 1 forward gear and 5 reverse gears, can I just spin my driveshaft the other direction to correct it or will that cause damage?
   The standard input direction for all Peerless transaxles is clockwise when looking down at the input shaft from above the transaxle.  In a low-speed 820 application like yours, I don't see a problem in reversing the input rotation.  Yes, if the transaxle is mounted so that clockwise input-shaft rotation produces 5 Forward speeds and 1 Reverse speed, you will have 5 Reverse speeds and 1 Forward speed with counter-clockwise input-shaft rotation.

Sincerely; Rodney
14  Mower Building / Setup Help / Driveline / Re: Shiftable 700?? on: September 21, 2014, 12:38:25 PM

    Who is this "fellow racer"?  Find out who it is -- he or she would best be able to answer your question.

    Theoretically, it would be possible to shift the 700 while running if you lowered the input-shaft speed, but to do that, you would need a smaller engine pulley, a larger transmission pulley, and a transmission sprocket about the same size as your axle sprocket.  You would also need to declutch before shifting while momentarily backing off the throttle.

Just noticed it said I had to be a dealer with a tax-exempt certificate with them.

   Do you know any local shop owners or business friends there who could order these for you?
