adapting older implements whose 3-p5 attachment points are too high?

[icehorse]

i have three old implements thatwork great except the attachment points are 4-inches too high off the ground for my L3901.

are there any kinds of adapters to lower the implement's attachment points?

 

[Russell King]

Buy something similar to this and weld it into place. Or just weld on some metal structure to lower what you have. Post pictures of the implements and you will probably get more suggestions.

It's called a saw or cutoff wheel and a welder.

I'm hoping to avoid welding, but it might be unavoidable.

Here's a picture of my old harrow. My old tedder is similar and the old tiller i'm borrowing is also similar. Specifically, the tiller is not mine to weld...

Whats too high about that disc? I have something similar and it works fine on my L3901.

The three pins would be much better if they were all 4-6 inches closer to the ground. For example my modern box blade's lower pins are about 15 inches off the ground. The lower pins on these older implements range fro5- 12 inches higher. I can barely get these implements off the ground for transport before my lower pins are at the very top of their range. I have an intuition that whenever possible we should run stuff in the middle of their operating ranges.

Shorten the side links. I am pretty sure my L3901 would have no problem with that disc.

Also look at which hole you have the tractor end of the top link in and shorten it some to make it lift higher.

That and check the feedback linkage adjustment. This is also where a hydraulic toplink shines.

Yea, you'll need to either put taller tires on your tractor, buy a bigger tractor, or rework the hitches if you want the attachment points to be lower.

I concur. ~15" above the ground seems to be the standard location of the lower lift pins on many modern implements. My EA box blade, EA land leveler and and Land Pride RCR1884 rotary cutter all follow this "standard".

The OP could buy and modify a Quick Hitch to have a more desirable offset .... maybe.

My tractor has a couple of different holes to adjust the lift arms. Check to see if your tractor can be adjusted for higher lift.

Once you get them up put them on pallets or other wood blocks.

He said the implement are too high already.
He would have to put the Tractor on pallets.

. So, drive the rear of the tractor up on boards/make ramps. It might not take much lift on the rear tires to put the 3 pt significantly higher.

Since the older implements worked fine for decades on older tractors, buy an older tractor !
As others have said though it's probably the 3PH configuration needs redoing.
Post a picture or two of tractor with implement,someone will know what to do.
After I converted all my 3PH to Snap Coupler, life got real easy. Any combo of implement(3) and tractor(4) was a simple 60 seconds on and gone.

I've never had a reason to fiddle with the lift arms on the L4240, but in addition to lower holes in the lower end of the lifting rods, the lift arms have holes closer to the tractor that would seem to provide lower position(s) at the implement end.

Maybe that's not even why the holes in the arms are there? I'm assuming there would be less lifting capability if they were used because of the leverage the implement would have.

That’s exactly what I was referring to in my previous post. It’s doubtful that reduced lifting capacity would be an issue. very few implements come close in weight to the maximum 3ph capacity.

Solution could be to lenthening your lift arms. If you have adjustable arms extend them fully. Otherwise they sell longer aftermarket lift arms. Not cheap but wull let you use what you have.
