picked this up at an auction last week. $130
its pretty heavy duty and has a large handle you can use to pull the spring loaded pin out and then rotate the blade with the lever so you don't have to leave the tractor seat. looks like someone extended the handle to reach the tractor seat better. To use it in reverse you have to get off the seat to adjust as the pin for that is attached but is not spring loaded and is tucked under the frame.
I cannot find a name on it. the tag in the picture only says genuine Timken roller bearings referring to the bearings in the main pivot. which spins very easily.
also has a wheel to adjust its own permanently attached top link, presumably from the tractor seat as well if you can reach it.
its 6ft and has a little wear on the outside corners but not too bad. since its so heavy duty seems like a decent deal for $130
anyone seen one before or know what brand it might be?
THanks.
