3-point - how high?

[dobiedisco]

How high should the 3pt lift implements? I'm a newbie tractor owner (old MF135) and apologize for the newbie question! I've been using a box blade to level my driveway and it lifts it maybe 2' from the ground to the bottom of the box blade. Thank you!

Lifting 2 ft isn't enough?

Make it even higher if you shorten the top arm.

That sounds about right. With longer attachments like a bush hog mower or tandem disk; you will have to shorten your top link to raise the rear of those longer implements.

it should lift it all the way up.

Unless you are hanging it up on something, I don't see why it makes much differece. I have to shorten the top link on mine when I load the tractor on the trailer or I catch the bottom of the box blade on the ground as the tractor goes up the trailer. But once it is on the ground, the top link has a big effect on the performance of the box blade when it is being used. Shortening the top link will cause the box blade to dig in deeper when it is being dragged accross the area. Too much, and it will stop my tractor. Lengthening it will raise the front of the box and eventually cause it to ride on back of the blade which is curled out allowing more of a smoothing effect with no digging in. Put it down on concrete and adjust the top link and you will see.

It is doing what I need it to so far, but I wanted to see if that sounds right. If it sounded lower than normal, then it would need to be checked out. It actually may be more like 18" to 2'...somewhere in that range. I will be hooking up the boom pole soon to move tree sections to the burn pile and just bought an auger and dirt scoop yesterday. So, just checking to see if it is within a normal range before putting it to work on heavier tasks. Thanks for the feedback...like I said, "newbie!"

My logic is, a car may drive on a flat tire, but that doesn't mean it's good for the tire or the rim.

:laughing:

Forgot to mention that it does shudder a bit when it reaches its highest point.

20"or so to the bottom of the implement means the lower links are 8-10 inches higher (or thereabouts). That's plenty and I doubt you'd see much more on any CUT.
Obviously, don't compare a CUT to a full sized utility tractor...but even those bigger machines don't have much more travel, but their rear tires are larger in diameter so that rear axle is further from the ground.
As far as the shudder, I suspect the lift cylinder is at or getting close to the end of it's travel. Could also be a little air in your hydraulic system.

There may also be a need for some linkage adjustment at the top end. Likely is something that feeds the hyd. system info when the top is reached so it closes off a valve.

You're getting plenty of lift. Think my BB only goes up about 18". The 4010 lift is FAST though. You can pretty much hit the lift at the end of a row, do a brake turn to the next row, slam it down and go onto the next row. The "slam down" depends on where you have the "down" valve adjusted. That's often not as fast.

Only time it doesn't lift so fast and high is regular lift with the bush hog on it. Only way to get the trail wheel very high off the ground is to crank the top link down tight.
