I guess I should've asked this at the beginning if anyone else has made a cassette using number 41 sprockets. I will stop in at the bike shop and ask more questions.

Looks like something you would use to follow behind a horse in a parade and pickup crap.

I definitely want multiple speeds. I'd guess your right that bike chains could handle a lot. The sprockets I would guess to handle less torque. #41 sprockets would make it strong enough to handle the torque of a riding mower engine. The bike tech I talked to a week ago said a bike cassette on...

Plow the sidewalk instead of shovelling it. I think pedalling would be easier on my back than a shovel. But then if there is a lot of snow or I am in a hurry I would get out the snow blower. This pedal cart is for: 1. exercise for me, especially in the winter time when a bicycle is not feasable...

The machine is not finished yet. I don't think that bicycle cassettes will handle the torque needed for the machine to plow snow with a blade on the front.

This morning I draped a loose #41 chain over a 20 tooth sprocket. Next to it was a 2nd 20 tooth sprocket. I pulled on the chain and angled the sprockets and the chain easily jumped over to the other sprocket. I think it could work.

This is also for my 4 wheel drive pedal kart project. After talking to a bike mechanic it sounds like a bike cassette (set of gears off of the rear of a multi speed bike) might not handle the torque of my pedal kart geared down really slow, and with a snow blade on the front. So the idea I have...

Good. I printed both pages.

I got a Comet F-N-R gearbox a week ago. I just got a 1" shaft that is 14" long with 1/4" keyway. Two 20 tooth sprockets are on the way. I have to buy bearings yet.

I see some for 3/4" axles. Does anyone sell one for a 1" axle?

Comet went bankrupt and another company bought them out. The F-N-R transmissions are being made again. I got a new one 10 days ago.

What are "RAGB & TC? I don't have the $$$$$ to do a shaft drive or any other version. Including Comet reverse gearbox I'm going to be spending at least another $400 on this project.

Does anyone have any suggestions of where to buy 3/4" and 1" shafts with keyways? The shaft does not need to be hardened. Also I will need one disc brake setup that is cheap to buy and it is for my 4 wheel drive pedal cart.

Does anyone know if there is a simple way to mount a 21 speed sprocket casette onto a shaft that is either 3/4" or 1"? The casette would be removed from the hub and the hole inside of a casette is plenty big enough for a 3/4 or 1 inch shaft. The shaft it would be going on is a Comet reverse gearbox.

In the 90s there were several companies making 4ws lawn tractors: MTD, sold under many of their brands like Yard Man and others. Their tractors had 4 bolt rear wheels and an axle that was f-n-r but not a really strong axle. Noma who was bought out by Murray in the mid 90s. They were sold under...

Well its "pedal powered" so its not going to be going fast or have to handle much frame stress. I'm on a very limited budget and I don't have a welder so this is how I'm doing it. If something breaks, then I will fix and strengthen it. I originally was going to use a little 3 speed with reverse...

January of 2012 I started building it with rear steering hubs, wheels/tires and the guts from a hydrostatic transaxle out of a Noma 4 wheel steer lawn tractor. I used gokart sprockets from Northern Tool. With a limited budget and health problems I worked on it on and off into March of 2012. I...

What are the specs on a 530 sprocket? I have looked at external reverse gearboxes and have never heard of a 530 sprocket.
