I am hoping to get a thread going for modifications or improvements folks have done to their DBs to make them more useful or to just keep them going. Have you made an implement? Made modifications so that your hood would fit? Have you improvised or made parts because you could not find the correct part you needed? I am not a purest but, I prefer mods that don't butcher the original equipment.

Here is first my entry. It is very simple but, something that I hope will get things going. It is a handlebar mounted kill witch. I used a kill switch from a dirt bike that I picked up at the local motorcycle salvage yard for free. I have a few other simple things that I can add to this topic later. I am currently working on an adjustable counterweight.

This wasn't my idea but was on the tractor when I got it . They used what looks like a screen door spring with a chain going to the sickle bar clutch, Normally the chain is wrapped over the handle bar and hooked to a long screw this keeps the mower off , the other end is on the rod controlling the drive clutch . When you take the chain off the screw and the drive clutch rod controls the on/off of the mower .Then the only time the mower is cutting is when the tractor is moving One handle controls both !

That's actually a pretty inventive way to get around needing to find the clutch rod and handle while increasing safety a bit. I saw somehere but can't remember where someone modified the clutch handle for the sickle bar. If I remember right ne brazed a tab on the bottom edge of the sickle bar handle that extended under the drive clutch handle so if the sickle was running and he pulled back on the drive cluth handle they would both disengage at the same time.

Not actually an improvement unless you're lazy like me. Here is a cart that I made out of a small lawn trailer. If you notice, I moved the axle forward to be under the seat which evened out the weight a bit. There is also ample room on the back for a cooler filled with what ever adult beverages you enjoy. Believe it or not, this cart had 4 grown men on it, pushing 800 lbs. The axle flexed a bit but it carried the load. The hitch is homemade out of scrapI had laying in the garage, sorry but I don't have a pic of that.

Clutch Lever
I believe this lever is for that purpose. This is from a "Super 3" tractor(575104)

I'll have to look if there's a second hole in the lever on mine .With the one pictured would you be able to run the tractor without the mower running then move it in a different position to make both mower and tractor run ?

that lever is mostly for tractors that have the adjustable handle bars...its so you can hook the clutch rod up to a better postion whne you lower or raise them up. There was a mower unit that used it and the hand brake units did also.

A long time back we used to get a monomtary contact switch and drill a hole into the end of the handle grip. By running a wire up the pipe handle, you had a kill switch with a cleaner look and no exposed wiring.

Here's the counter weight. A bit crude since I just used what was lying around the garage.  I can use any combination of 2 1/2#, 3#, 5#, 10# weights. Not as spiffy as the original DB item but, I believe it will work well.
