Spike Tooth Drag Harrow

jackjack · Mar 30, 2020

Hi Everyone,

first time posting and I'm in need of some help. I recently got a spike tooth drag and its in OK shape. But last night I was looking it over and there is no adjustment on it. No lever to move the spikes from aggressive to less aggressive. Is this something i could fabricate myself? Does anyone have one they could take a picture of, or any ideas to make this easy?? Any suggestions???? I am using for our property and would really like to use it soon for some deep thatching and some seed prep. Thoughts ?

Sounds like you have a homemade section,---that being the case , I think you will find it best to find a real harrow section. All I ever had/have were/are adjustable except a brand called "flex harrow" which are non adjustable and roll up when you try to lift them,--"finger mashers" as they were called. Flex harrows were never designed to be adjustable----never did a good job either.

Perhaps suspending harrow from a Three Point Hitch boom pole.

Looking at photos, https://duckduckgo.com/?t=ffsb&q=spike+tooth+harrow&atb=v169-1&iax=images&ia=images it looks like some adjust and some don't. If yours is one in which the spike-mounting bars can rotate, you may just be missing the handle and latch. If the bars can't rotate, you have lots of work ahead to make it adjustable.

Pics of your Harrow would help us give you better info.

I don't think there's any way to make the spike harrow less aggressive without nearly building a new one from scratch. Possibly loosen the spikes and retract them up so the chassis slides on the ground like a land plane? Anything beyond that you're getting into a substantial fabrication project to change the crossbars from fixed to rotate-able.

Anyhow here are a couple of posts describing my spike harrow projects, with photos that might give you some ideas.

1) $100 for this spike harrow that the P.O. just dragged with a chain. I fabricated a cross-bar with 12" chains to pull it evenly, and a lifter mechanism (re-purposed from an abandoned exercise machine) with a pulley that raises the harrow, and pulls it toward the tractor, for tight turns where my orchard rows reach the fence.

2) Photos of the spike harrow that show clearly how the adjustment levers work ...

It's not clear in those photos that I added another feature: My use is in an orchard. Its easy to get too close and snag the harrow on a tree. So in addition to the 12" chains that pull the harrow behind the drawbar, I also added chains that go out from the tractor's differential to the outer corners of the drawbar. These are to take the shock of snagging on a tree, to stall the tractor instead of bending the spike harrow's drawbar.
