I have a Tak TL140. The float function for the bucket takes a very long time (read: as much as 20 minutes) of run time before it starts functioning, but when it starts working it works fine for hours. If I shut the machine down and immediately restart then it goes back to the waiting game before...
Did you ever figure out the problem? I am having the same issue, but see there was never a reply. Forums are great as long as it's more than a one sided conversation...
Can you attach a small grapple bucket to a 610? I'm a contractor and would like to be able to pick up debris piles and such but a regular bucket doesn't cut it. Will the bucket make the unit "top heavy"?
