3 Point Float Catch, Kubota BX

[seajbee]

Greetings all, new here and first time posting.
I have a '26 Bx 2680 with QH05, FDR1660, GS0550 and a generic 12V 45gal sprayer from TSC. I'm loving it so far. However, I want to fab up something to lock down the 3-point adjust lever so it can float at the lowest level. What I have in mind is a plate with a cut slot and a "detent" cut at the bottom (similar to the PTO engage/disengage lever) Ideally, I would mount this on the underside of the plastic lever housing. (I don't know the proper term, but the plastic "trim" on top of the fender that the levers travel in.
Has anyone done something similar that could share pics, tips, tricks or any better ideas? I'd like a better solution than just using a bungee.

Thanks!

I'm not sure what you're trying to do exactly.

The 3 PT. has no downward force, it can only lift. If you set the 3 PT. down to it's lowest point it will float on it's own, you don't need to "lock" the lever in position. If you want to limit the amount of float (using the GS550 say) you would need to add weight to hold it down.

I believe if the lever is forced to stay at the down limit (as if you were pushing it by hand and holding it there) it could cause damage to the relief valve or hydraulic pump over time.

Thank you for the reply. I'll do some more research to see if there is a risk of mechanical damage. I do know that there is no hydraulic downforce, and that the rear implements will float up. The issue is, they will only float back down to the previously "set" position. A true 3 point float would allow the implement to follow ground contours all the way down, to the absolute bottom limit of the 3 point's mechanical range. That is what I'm trying to accomplish.

Example- I'm mowing on level ground with my rear finish mower. I back the rear mower down a ditch bank. The rear mower wheels will no longer contact the ground unless I manually lower the 3-point further.

Some BX owners bungee their 3-point lever. I'm just looking for a different way of accomplishing the same thing

I've checked the schematic for your tractor, and you won't be deadheading your pump by holding the lever down. Perhaps fab a little latch similar to the clutch latch on some models.

I didn't THINK it would but I wasn't 100% sure. Thank you for the confirmation.

Ditto - just wanted to be sure.
