I have been using the Cayman Vario 60S TWK walk-behind tractor for 2 years. for all the time of operation there was only one case of malfunctions in operation. I lent it to a friend for a while, after they returned it to me, the motor began to troit. I had to regulate the air flow damper. On the occasion I drove to a service center, changed the carburetor under warranty without any problems and questions. He began to work even quieter, although before that it was not too loud. A very important nuance in operation, all parts must be with serial numbers, in the service for a long time they were surprised at the lack of a serial on the carburetor, but changed. The only weak point is that you can’t carry it on its side, if the channels become clogged, then at least rinse, at least clean, but the speed is floating. He keeps the load while floating, but why spoil the good equipment.
The only drawback that I noticed was that the ends on the rubber control sticks quickly erased and they started to scroll, so it’s better to immediately wrap them with electrical tape.
