Just this week, (12/10/2023) pulled mine apart because of shift issues. My gears no show signs of water or rust. The problem was a wallowed out shift shaft. I ended up tack welding the attachment to the shaft. Easy to get to with a grinder in case I need to in the future. Glad I took it all down. Now I know very got a good machine. Thanks to folks like this for an excellent guide made the job easy.
I had this problem with a tiller! Instead of splitting the whole machine in half just cut a hole in the right side (you facing the tines) so you can axess the shifter gear the stick a screwdriver in there and manipulate the gear while moving the gear shit and you can get the gear to let loose in the linkages. When your done just weld the piece of metal u cut out back where it belongs! About 20 minutes verses 4 hrs!
These types of tillers have to be kept out of the weather and oil the shifter shaft often and move it back and forth often Cheap until but works great if you don’t abuse it
Suspect a broken drive chain on mine. Watching a few of these repairs and thinking that it looks possible to lay the left side down and remove the right side for the work needed. Am I seeing this right? Both wheels are seized and I’d rather only fight the right one and not both. Your tines came off easily. Do these not rust on to their shafts? Thanks
