I have a Burns by Gilson tiller

Model # 51011 then on over it says 43788

Serial # 57B5397

If anyone can give me information about it or maybe has the manual and would be willing to send me a copy of it please contact me. I need to know what the part numbers are so i can buy parts for it.

What i need is what i call the engage arm the pully on it the bearings are shot and its not turning like it should and need a new one but not sure what part number it is.

Any help would be appreaciated.
