Advice for replacing chain with belts

[bmaverick]

Hello.
I have a two wheel japanese tractor 8HP. There is a chain 10B between the gearbox and the tiller. I cannot find the oil seals for the chain box and I also want to attach different things, not just the tiller. So I decided that I should replace the chain with belts. But I do not know what kind of belts. Can someone help me?
So far someone told me that it should be toothed belt, so that it would not slip. Another person told me that two normal belts might work, I think you call them V belts. The same V belts are used for the connection between the engine and the gearbox. I have no idea what kind of toothed belt would be sufficient. I saw T type belts online, maybe T10 25mm? Or two V belts would be enough? I am attaching some photos of the machine.
I also saw that there is attachment in Japan for digging potatoes. It is connected with single V belt. But of course the load would be less than the tiller.

Did your YS80 come with the tool pack? This should be all the tools needed to work on the machine and to disconnect the rear tiller.

Looks like a good ap for a Poly-Vee belt. Like the kind on a modern car that runs the engine accessories. Much higher power transmission capability, less slipping, cooler running. Leave it a bit more loose in case of a big jamb up, and it'll slip a bit instead of do damage. A timimg belt with teeth is another option but more complicated and will NOT slip which could cause damage, but the chain never slips either. Most of the challenge is getting the pulley bore's spline'd to fit the shafts. A tentioner needs to be fitted as well. A machine shop could get it done. It similar to the type of jobs I've done for myself and others.

Thank you for the files and advice. I actually bought one of those chinese flail mowers? and it is the main thing I want to attach in place of the tiller. But the chinese tractors have gears at the back of the gearbox, not like the japanese shaft at the side. So I need belts for it too, preferably the same type.

Someone said I should look at car timing belt, specifically 1.9 tdi. It has 30mm HTD belt. Quite expensive compared to V belts, but maybe it will work?
I did not consider poly V belt. I will now. Thanks.

There is a place here that will make the inner splines. A person there said toothed belt, so it would not slip. I think probably because the tiller is quite high load?? I have seen flail mowers with belt connection, but never tillers. So I guess I am doing something stupid, but I think I do not have a choice.

You know, along with listing your tractor you can also list your location. Nobody is gonna hold it against you if you are in Europe or anywhere else.
