Lower Control arm pins

[PineRidge]

Until recently, I never really thought about where I should place the pins on my lower control arms. Then, one day, I mounted a new implement (snow blower) on the lower control arms, inserted the lower control arm pins in the holes that have no "wiggle". Drove around, operated the snow blower, checked balance and generally had a great time. Then the trouble started. When I tried to get the lower control arms off, the pins were so tight, they would not come out. Stuck!! Pinched so tight I could not get them to slide free to allow the control arms to spread wide and come off the lower control arms supports and release the implement. After an hour, I finally got them off and was able to release the implement. Now, this is my question.

Should I use the holes on the lower control arms that are long and oblong? These holes allow some movement side to side of the implement. Is this bad thing? Implement specific?

Guess everyone has their own way of doing things.

Once the implement is connected to the 3-point I slightly raise the implement, center the load from side to side, and drop the 1st pin in. I then rock the implement to the opposite side and drop in the second pin so there is little or no side-to-side movement.

To remove the pins leave the implement in the air and as you rock it from side to side pull one of the two pins, the second will come out easier than the first.

That's exactly what I do and it works well. The B7100 had turnbuckles on each side with a locking nut. I've seen many smaller tractors with that arrangement, and wasn't real sure I'd like the pin in hole style when I was tractor shopping. Now, I wouldn't trade back. Some of my stuff has non-standard pin widths, but you can still get things to fit if you don't think you need to use the same hole on each side, or are willing to use an oblong hole on one side.

Thanks, I tried it for a quite awhile doing exactly what you said, but it was just right and stuck so tight with neither pin wanting to budge.

Did you try a BFH Bob?

Big F### Hammer? Yes, and it loosened the pins but did not dislodge the suckers. They were "welded" in place by the pressure. I was embarrassed!

PS I had to ask my wife for help! Feel my pain!

Don't sweat it. 3pt and/or tractor hitch hook ups are deffinately one of those tasks that you just get better at over time., and take time to get better at.

When I first bought a 5' mower.. it took me the better part of 15 minutes to keep backing up getitng things lined up and getting it hitched... that eventually worked it's way down, as I learned to bacup better, learned where to put the arms.. learned where to park the mower in the first place.. how to crib it up, safe but effective use of various prying and pounding instruments.. and now it's under a minute..

I can now back in and hitch my 10' mower in almost the same time.. and no prying or pounding helps.. the mower weights close to 3k#.. so you just have to hit it straight and leave it straight when you park.

I'm sure the same applies to those with quick attach loaders, and mid mount mowers... First time you take it off/on is the longest. Fast forward a few years and it is a piece of cake..

Like I said.. don't sweat it... You will either get good at doing it, or you will get good at finding a way to do it.
