L3902 - Implement Limits for Harrows

[JohnnieSegment]

Hey all,

New L3902 owner here. I have been surprised by the fairly low implement weight and size limits listed in the owners manual. One implement I've always wanted is the "Power Harrow" which stirs the soil horizontally, vs mixing it vertically.

Found something that matched my HP - the Kuhn HRB 122 (https://www.en.kuhn-canada.com/crop/tillage-tools/secondary-tillage/power-harrows/hrb-102)

Problem is, there's not comparable tool with a listed weight limit in the manual, so I am kind of guessing here. Something tells me that dragging those 1,080 lbs of steel turning through my heavier soils would be outside of my machine's tolerances (despite front loader/bucket, despite loaded tires).

Questions are:
Am I probably correct that this implement is too heavy for my L3902?
Is there a power harrow out there that I should be looking at instead?
Is there maybe another implement that will do the job I am shooting for (horizontal, NOT vertical agitation)?

Thanks for any hot tips.

If you get a width to cover the width of your tires, maybe some more, you should be good to go. Probably should run it in 4WD with loader attached.
Updated: Looks like you need the 152 model.

Where did you get that it's outside the limits?
The L3902 has a three point that will lift 1985lbs at the pin and 1433lbs at 24" behind the pins.
The unit that your looking at is only 1,080 lbs.

I was going by PTO minimum power requirement. I think the L3901 max PTO Hp is 33.
