[moderator note]: I "split" the related posts on the brake master cylinder here from the general topic "What did you do to your V11 today ?" for better archiving. Yet, because they predate this topic origin, this topic now appears to have been started by @skibum69 rather than the original poster, @Revilo. Sorry for the change-up, folks. Just trying to keep things tidied-up and searchable.

@Lucky Phil just posted these links to front brake master cylinders in another thread. [I have "split" those posts here and they are seen as the first posts in this thread, now.] I have rebuilt my clutch master twice. The 12mm kit is available as Brembo part number: . OPPracing may be a resource for the brake parts, as well. https://www.oppracing.com/product_display/202872-brembo-oe-spare-part-master-cylinder-brake-12mm-seal-set-for-front-master-110436292/#&gid=1&pid=103200

Is that an antitheft technique?

Only saying it looked like that model. Not really sure what it was or if I have any way to find out. Likely it was simply a "275" (or similar) with no prefix. Certainly it was a product of the sixties and I am not kidding about the sorry brakes as well as the way the mower would drive the tractor, relentlessly. I clearly recall a dive down the side of a creek bank standing hard on the brake and clutch pedals, while pulling on the steering wheel to give it everything I had, and still being driven to the creek. Impressed me as bull riding, where in the bull does not give a twit about what the rider might care for. Considering a tractor for groundskeeping these days, I would be averse to "vintage" offerings, no matter how quaint, and go for modern, including rollover protection systems.

Ferruccio: "That will be pretty good. Let's get on with it " . . .

This IH B-275 looks most like my old tractor, @gstallons. And I do remember the term "live PTO", @MartyNZ. Pretty sure that is contrasted with "dead man's PTO" . . .

Day one with mySport: twenty-five years ago today !

Is this the bent plate, @Cordwainer? #2 GU01433400:

Wow, man, no idea. Something along the lines of a 360 or this 424, maybe it was a little bigger (over thirty years ago, now) . . .

I recall my IH tractor was maybe 30 hp, gasoline, and pulled a five foot "bush hog" (flail blade mower), five foot box blade, and would (barely) lift a boom with the 3-point hitch. It was probably from the 1960s and I got a ton of work done with it on that thirty acres. Apparently, something known as "brakes" were discovered sometime after it was built along with a clever mechanism that disengaged the PTO (Power Take Off) when the engine-transmission clutch is disengaged. I am sure that device has a name (?) Without the clever device, depressing the foot lever for the clutch does, indeed, stop engine power from driving the tractor. While the inertia of the spinning flail blades continue to drive the tractor along its path of travel, usually to some ill purpose. Did I mention the brakes . . .

For better discussion, this topic has been moved from the "Wanted" classifieds to Technical Topics. No doubt, the Rube Goldberg affair that serves as the V11 sidestand is a potential Achilles' Heel. The lower fastener is known to loosen and the large, upper fastener into the timing chest is to be torqued to 70 Nm. The complex mounting plate looks to be a casting (?) . . .

No one has ever heard the phrase, "Sorry I got that Kubota" . . .

After downsizing to 3 1/2 acres, I could no longer justify a full size tractor. "MrBill " is a single cylinder flat-head Briggs&Stratton ( 2nd motor, 2nd deck, 2nd transaxle) now in (light duty) service for his thirty-fifth (35th!) season. "Swampee ", the CubCadet, runs a 750cc Kohler air-cooled V-twin and came to me with a dubious history that may-or-may-not have involved some sort of swamp racing. Both are MTD products from Ohio, USA . . . Swampee has long served as my Hawker Odyssey test bed, running one of my PC545 out to its fifteenth year . . .

I thought this Ford was an 8N? We always called those RedBellies, but I learned they are also called "Boomers." After I sold my International Harvester, and thirty acres, Ford-New Holland built an homage Boomer 8N. Never even seen one, but had a hankerin' for one . . .

You've got this, bud!

Here is a good discussion of the issues and several solutions:

About?

@Desdinova, Here is an image of the battery/underseat with some modifications. There are "junction blocks" added behind each of the battery terminals to reduce the of ring terminals and add accessories. Others ( @Tomchri) have added "L"-shaped brackets to the battery terminals to bring the terminal stack paralell to the top of the battery and more accessible. Also, the battery basket, in the factory location, stands the front of the battery quite high beneath the seat making the terminals even harder to access and allowing the seat to put pressure on the battery under the rider's weight: Moving the front mounts of the battery basket beneath the subframe addresses this. Below, relocated battery basket in the foreground, prominent front corner of the factory position visible on the Rosso Mandello in the background: P.S. - Another image with the battery basket in the factory position (front mounting tabs above the subrame) showing seat damage to the battery hold-down strap: Detailed view of the mounting tabs below the subframe:

It seems the (one-and-only?) V11 Sport Playboy Exclusive Edition has never resurfaced. The one V11 SpineFrame I would consider building a "tribute"/ homage . . .

I have so enjoyed this fellow's writing in Cycle World ("Leanings") and Road&Track ("Side Glances") over his motojournalist career. I ran across this image I saved of his take on "Beatnik Bikes" . . . . . . and wondered what he is up to lately . . . Turns out: new book! And a nice article about the man and this book: https://thevintagent.com/2025/07/24/peter-egan-landings-in-america/

Much like Guzzidiag cannot be used to set the TPS baseline I did not think it sensitive enough to detect subtle failures in the TPS progression.

The original V11 Sport/LeMans "Spark 500" battery OEM is the Hawker Odyssey PC545

Is she is, or is she ain't . . .

Cannot wait to see, and hear, more from @Scud how this V100 compares to the various V11 SpineFrames he has owned!

A question for @Pressureangle . . .
