Ansung - Terra Force YJC 074 Tiller Repairs
The spline shaft broke from the rotor shaft.
Also noticed missing support bolts and welding cracks. Gaskets need checking as well, there are some dark spots indicating leaks.
Guessing that these things might all be related, as in one thing caused another.
The facts are, a high-speed rotary tiller has significant force. Now I have a much better idea on what bolts, nuts, etc., to keep a close eye on and make sure they are proper and tight.
The contact at Terra Force was superb.
Timely, detailed, and accurate answers. I cannot thank them enough.
When the mechanic came to assess the situation, he confirmed exactly what the Terra Force representative said.
The mechanic also commented on the
1) Quality engineering
2) Mechanic / repair friendly design.
This was the 5th season of use. The unit has not been abused or seen excessive use, but I obviously did not see those bolts coming loose/out.
Glad to own a quality piece of equipment.
Glad to choose this brand and model.
