Class I three point hitch specs?

[Fawteen]

Grandson just traded for a new John Deere 3039R and the 3 point travel isn't what it should be. If he adjusts the lift arm links long enough to get the tiller in the ground, he can't lift it high enough to get it on the trailer without dragging. Conversely, if he adjusts them short to lift it enough to get it on the trailer, he can't get it into the ground.

I understand that approach angle has a lot to do with it, but it sure seems to me like the lift arm travel distance is too short, possibly due to issues with the rockshaft. Before he takes it back to the dealer (again...) it'd be nice to know what it's supposed to be.

On my Kubota B2650 the lowered position is 8 inches from ground to center of the eye on the lift arm, and 27 inches in the raised position.

His measurements are 8 and 19. 7 or 8 inches difference in lift height doesn't seem right.

Looking at the Operator's Manual download from the DeereTechPubs site, it has a ''limited category 1 hitch''.

Probably the arms are shorter than the old classic ''N'' Fords that the Category I spec derived from and don't swing over as wide of an arc up and down.

The O.M. gives guidance as to which of the three attaching holes for the top link to use for various implements, with the middle hole being suggested for tillers, giving some forward angling as the tiller lifts. (It involves draft, as well, when OPERATING the equipment.)

Perhaps moving the link to the lower hole for transport would give enough additional forward tilt to help in loading?

Without any thing on the 3pt, have it raised up, if you can't lift it anymore, then that's just the way it is. If you can lift it by hand more than yes dealer problem. Does the manual say anything?

Key word is, ''[u:1147af347e]limited[/u:1147af347e] category 1 hitch''.
Ford 8N is 8.5 to 34.25 (25.75 travel).

On some of those smaller tractors there is a different set of mounting holes were the lift links actually hook to the arms. Maybe needs to be adjusted in the other setting? Would a different length top link make a difference?

Really it should be called Cat 1/2 hitch,they are about half way between a Cat 0 and Cat 1

will get slammed but the three point on Kubota suck the travel range is to short
