Looking for advice on basket case tiller

modifyit · Jan 20, 2012

I have a tiller for a Satoh beaver that was acquired disassembled. There are no identification tags anywhere on the tiller. In attempting to put the thing back together some questions have obviously come up. The gearbox is a 2:1 ratio box, and if the input shaft is driven by the PTO at two revolutions to one revolution of the output shaft, what size sprockets will be needed on the final chain drive to the tine shaft? There was only one sprocket in the bucket of parts and it is a 14 tooth sprocket for #60 chain. I don't know if this sprocket was used on the tiller originally.
Any help will certainly be appreciated. I've been stumbling over these parts in my shop for a couple of years, and would now like to get the thing back together, out of the shop, and in service.

Thanks

I think your going to end having to find a Model #.

In the manual for my MT372 there is a section on a tiller. Perhaps if you have access to a manual you might find enough information to noodle out what model tiller it is.

There isn't much hope of finding a model number, but I have researched other models online and from the parts description in some of the online manuals, the chain portion of the drive should be anywhere from 1.5:1 ratio to 2:1 ratio. The main drive gearbox is 2:1, so those ratios will be my starting point. I suppose in the end, it will depend on the PTO output RPM and maybe some final sprocket change to correct the ratio after the tiller is tested.
