MAXIM Chain Drive, Heavy Duty, Compact Commercial Rototiller. Honda GX120 4hp motor with electronic ignition.
Not currently running but should with included coil & carb kit. Fairly simple install but I've no time to do so. Fresh oil and stored with dry fuel tank. Front weighted by motor placement. Wheel assembly rotates up so full weight of machine is applied to tilling force vs light weight homeowner tillers that bounce all over. Stored in box trailer for 10 years. Outside under tarp last 6-8 months.
New version of this machine is about $1700. Cheapest similar around $1200.
This is how is, way is, as is, no guaranty sale. If you're handy with small motors and have couple hours you can probably resell for $250-$350 or use for many years to come.
