Here is one of my spring cultivators.
There are six with a 7 inch wide pointed spade tip like this and one with a 2 inch wide flat spade tip.
These cultivators came with the 1948 Ridemaster that I got out of Illinois a couple of years ago.
That tractor had a tool bar that was different from the tool bars on my other Ridemasters.
Here is the regular tool bar on the Ridemaster that I'm working on now.
It is a 2 inch square bar with two vertical mounting brackets welded on top of the bar.
This tool bar is 40 inch long.
The tool bar on that other Ridemaster was 60 inch long and it was welded behind the vertical mounting brackets ( not under them ).
I sold that 1948 Ridemaster to a guy out in Pennsylvanian.
When he came and picked it up the wide tool bar was still on it and I didn't even think about it at the time so it went with the tractor.
So now I'm ready to mount these cultivators on my 1947 Ridemaster and they don't fit !!!!
The lower lift bracket on the tractor has a round crossbar running between the two side brackets that the lift spring it attached to.
There is not enough room between the square tool bar and that round crossbar for the spring cultivator.
Also if I mount all seven cultivators on this 40 wide inch tool bar, there isn't any open space between the spade tips for the plants to go between them.
I'm going to have to make a tool bar like what was on that other tractor.
My wife is picking up a 5 foot long section of square tube today after she gets off work.
Meanwhile, I have cut the old tool bar off the vertical mounting brackets.
The lower front corner is trimmed off at a 45 degree like the other tool bar brackets were.
The vertical mounting brackets are bolted back onto the lift arms and ready for the new tool bar to be welded to them.
I've fastened a piece of 2 inch square tube in one of the cultivators.
Holding it up in position where the original tool bar was, you can see the front curve of the spring comes to about the center of the round crossbar.
Holding the cultivator in the position of the other tool bar, you can see that there is a lot of room between the tool bar and the round crossbar.
This also raises the cultivators up a couple of inches for more ground clearance when the tool bar is raised up.
This will sure help for loading the tractor on the trailer.
I know these spring cultivators are not Bolens factory implements so this raises some interesting questions ......
1. These cultivators are stamped " made in South America "
Were these made as an after market cultivator for the Ridemaster tractors or are these something that some farmer adapted to fit his Ridemaster?
2. If they were sold as an after market implement for the Ridemasters, did they came with the 60 inch modified tool bar or was that built up by the farmer.
My answer to both of those questions is, I don't have the slightest idea if they are a factory made accessory or if they are " farmer adapted ".
The welds looked very good and the 45 degree cut corners on the mounting brackets were smooth and even.
They looked more like factory than home made especially taking into consideration that this was probably done back in the 40's or 50's.
I'm sure that in the 11 years of production on these Ridemasters that a lot of them were shipped outside of the US.
I have never seen another Ridemaster with these spring cultivators on it and Hank Watkins ( the Bolens expert ) has never seen or heard of any either.
I suppose that these could have been made as an accessory for the Ridemasters and just sold to the farmers down in South America ?
At any rate, they came with a Ridemaster that I bought so I'm going to use them even though they are not Bolens factory implements.
