    I am looking to buy a edger engine (2 HP B&S, older, but it runs apparently) and a trailer See pictures.

    Owner of the engine wants $15
    Owner of the trailer wants $90 (must be newer, maybe I could talk him down)

    How hard would it be to mate the engine to the rear wheel? I think the edger has a pulley system. Would it be easier to use pulleys to connect to the wheel.... or is there not enough room and I would need to use a sprocket?

    I would rather not go friction drive, unless that is the only option.

    Give me some ideas so I can decide if I want to buy the engine/trailer.

    Do you think this would be a good setup? What parts would I need to buy?

    JMO, you could make a trailer which would be much shorter than this 35.1-inch trailer.

    Look for MotorMac and S.Baudry's trailers on this forum and pick up pointers. MotorMac's trailer is especially compact and tucks close and to the right of the rear wheel.

    I am using this design as a model. I like its simplicity.

    I just bought a 196cc 6.5 hp engine from Harbor Freight. Now I am researching the best parts to get.

    I like the idea of a 50mph push trailer, but it also scares the **** out of me... that sounds so dangerous.

    I put in a couple of photos to show how easy it is to add a pusher. One is obviously made from a mini bike with the front missing and the drive bar added instead. The other is the famous motor wheel, I put it up to show another method you could use, it would be difficult to reproduce in that fashion but you get the idea for a placement. There is one out there that uses the idea of the wheel next to the bike wheel, only his is a small wheel with the engine over the top driving down to the sprocket on the wheel. Have fun, Dave

    I really like that mini-bike trailer!

    If building a trailer, I HIGHLY recommend good bearings. I was using the regular cheap bearings, and would replace them almost monthly! Get some go-kart bearings at www.mfgsupply.com and they are only 2.00 each.


    I replaced all 4 of my axle bearings, and wheel bearings with them and have had no failures yet. However, they are press-bearings and I recommend grinding a slight surface of metal out of the middle of the bearings so they slide onto the axles and won't need to be pressed. (use a dremel with a chainsaw sharpening stone to grind the bearings)
