I suddenly have downforce ?

[stihlhawgin]

Been using a cub 149 for about 30 years to mow and push snow, but ever since grandpa brought that first one home when I was about 8 years old, I always longed to see the three point lift something anything. Well about a week ago I traded for a brinly plow, cultivator and a 1a tiller. So after looking at many pics and a schematic that I found here. My son and I fanned up a sleeve hitch.

Everything has been working out great except the learning curve for adjusting the plow.

Anyway the other day I hooked on the cultivator and for no reason I now seem to have downforce or pressure. My garage and cubs are a couple miles away so I haven't been able to check it out yet. Hoping someone might know why I all of a sudden have down pressure but never changed anything. Before I could always grab the three point and lift up . Any idea's appreciated

Pic of sleeve hitch my son and I made. Lift bar and straps are temporary but work fine till I find some proper bar and flat stock.

Did you do something to the float lock-out pin? Take the tunnel cover off and look at it. You should be able to see why it isn't floating.

Thanks for the response, I haven't changed anything under the tunnel since putting the three point on. It's like it just locked by itself while testing out the cultivator. Hopefully I'll get to garage tomorrow to check it out.

Were you welding the hitch while it was on the tractor?

[stihlhawgin]

Nope I've taken it off each time I sparked the welder .

Wandering what could have happened if I did weld while it was on though. Always eager to learn

if it was working after welding, it is okay.

Depending on the grounding path when welding, a pivot point could have arc'd and tack welded itself together.

Does it now have actual down pressure or just resistance to being lifted up by hand?

What size/grade bolts did you use? The bolt in your top lift link looks 3/8ish? If it's not grade 8, then it or another bolt may have bent and is binding when you lift by hand.

Thank you all for your help, it ended up being the locking pin under the tunnel . Not sure how it locked. I'm pretty sure it was floating before, just glad to have it working. After about 30 years of waiting I'm finally ready to play in the garden.

Mounted up the earthway planter today also, guess those pics should go in the implements section though .

Glad you got it figured out!
