Brush hog keeps popping off the Kubota QH15 quick hitch

[bcp]

If your flex joint is in front of the A-frame, it can pop off. If you move it behind, it won't.

^^that^^ plus bushings on the draft pins should make for a very secure setup.

Never seen a problem using this type of bushing. Even with loose fit Harbor Freight quick hitch and multiple implements. Zero problems with QH15 also.

That spring loaded latch on mine, I can grab the handle and pull it straight up in the latched position. I can see why the brush hog pops off. I don't see how mine stayed on!

The latch is spring loaded and with significant force it's possible to pull up with levers down. They don't lock solid in place. If yours moves easily up with levers down it's a hitch problem. This should have been easily detected by your dealer when setting up. It would take a unskilled person not to notice this. Someone that shouldn't be setting tractors up.

What kind of quick hitch adaptor bushings did the dealer set up on the implements?

Here's some photos of a functional QH15 purchased recently. Also top link adaptor for implements not top QH compliant.

How snug do the implement pins fit the slot of the quick hitch,
many quick hitches need bushings installed on the implement pins.
Many of those bushings also have a shoulder to keep the implement aligned.
How is your toplink connected especially on a brush hog, the top link connection needs to have some flex or float to it,
without that when the tail wheel pushes up it will try to disconnect the top link.

It says error but it just worked for me.

My first thought.....

Ditto on bushings....

When your bush hog came off what did the part of the driveshaft attached to the pto shaft do?

When your bush hog came off what did the part of the driveshaft attached to the pto shaft do?

So the first time, the whole thing came off and the drive shaft disconnected in the middle . Was easy enough to get put back together. The next day is when only 1 side disconnected and the QH was just enough in a bind I couldn't move it.

Update: service guy came out, jumped on the hitch and it dislodged it. I didn't think to jump up and down on it! Happily, I wasn't doing anything wrong. The hitch had come defective from the factory. One side was missing a pin that keeps the spring loaded arm from displacing up which was what I thought. I thought you could just put a bolt or cotter pin in it but he gave me a new hitch and said they would send this one back to the company. I was so happy to find out it wasn't operator error!

Glad everything worked out ok! Sounds like you have an excellent dealer.

Ok quick question. I incorrectly stated the QH is a QH15, as I am on the Kubota site looking, I actually have the QH05 and the manufacturer says 28 HP max but it was put on my 3901 which is 38 HP. Is this an issue? The recept says QH15 but it is the 05 that they installed.
