Spring tooth harrow

Thu May 01, 2014 9:00 pm

I'm not sure if this the correct forum to ask this in or not.

I just picked up this very old, what I'm calling a spring tooth harrow. I am clearing my lot that was once home to a antique car salvage yard and I'm wanting to drag this around to help loosen up the ground and bring up old steel from grandpa's salvage yard. Finding me a lot of parts from the teens and 20's, lol

I'm not sure if my old Cub will drag this section of harrow around or not, I'm not even sure how to set the spring tines to dig in or not.

Any thoughts and will this even work?

Thanks, John

I'd call it a spring tooth harrow too. I bet if you pulled that handle all the way back, the teeth would curl under the frame and be ready for action.

Only 8 teeth, Cub would probably pull it fine as long as there's not too much weight on the harrow. I guess this implement would be used to cultivate between rows? Hard to tell the tooth spacing from the picture.

Cub will easily handle the harrow. You will need a clevis to attach the chain to the Cub's draw bar.

The lever is used to adjust the angle of the teeth. Just squeeze the trigger on the handle and move the lever.

You may need to lubricate the pivot point.

I've always thought one would be handy, the ones I have seen before we're more like spikes with the adjustment handle. I'm hoping this one might give more when I hit something solid, which is going to happen.

I don't have my rock shaft or a fast hitch on my cub, I assume a chain through the clevis is all I need?

Actually the entire implement will jump if one of the teeth catches something substantial. Same thing happens with the peg toothed harrows.

Depending on soil condition, this harrow or a peg toothed harrow may just be able to scratch the surface. And perhaps not.

If you think there is buried stuff in the ground, might want to get a ripper to plow/tear up the ground. Then hand search for chunks of metal.

I have 2 sets of those harrows. They are IH I believe and come in sections.mine are a set of two which cub pulls easly and a bank of three that fold up.I haven't reseached them yet but I would guess they are horse drawn by the handles at the rear,where tractor stuff is usesually in front.
they work well in gardens or small field work,but my take a few passes on harder ground.

Yep, your cub will pull it. Lots of Multi-section spring tooths have been cut down to smaller, more manageable sections.
The original way they were hitched was usually 2 pcs of chain connected to a big "bull ring" that you could slip over a ball on the drawbar. A non-twisted clevis would work, but a twisted one might want to make it pull uneven.
It's a good tool to level up washouts, and would be good to pull up trash like you're planning.

There appears to be a bolt, forming a loop, in the portion of the chain laying on the pickup's bed. Slip a clevis through the loop and then pin the clevis to the draw bar.

Can't really tell, but assume the opposite end of the chain is bolted to the harrow's hitch.

Yeah Eugene, you're correct, they had a chain through the mount and I have a clevis already on my drawbar. I have a guy coming with his box blade and his tractor (bigger IH) and after he gets things knocked down, I'll harrow the heck out if it all.

Thanks for the most excellent advice!
