Older tractor with rotary mower gouges dirt

[Smokeydog]

My old MF135 had draft control on the 3 pt lift. Yours? Shouldn’t drag except over rough ground.

If you mean the second lever on the lift, yes it has one but I have seen no results from adjusting it.

I will try the check chains. Thanks to all for the feedback.

If your Position Control is functioning properly you should have no need for check chains.

3-Point Hitch - Kubota B3300SU + Zerco Check Chains + King Kutter Rotary Cutter

The Kubota B3300SU ( 33-hp / 1,800 pounds ) does not have POSITION CONTROL for the 3-Pt. hitch. Instead the B3300SU has 1/4"ing adjustment of the 3-Pt hitch, which is useful in its own way, but is NOT position control. When using a rotary cutter ("Bush Hog") you wish the mower deck to return...

The crank adjustment on the right side looking from the rear is frozen and will not turn.

If you use non-standard words for tractor parts it is very dificult to troubleshoot via the web.

I presume the "crank adjustment" is adjustment of the right Lifting Rod for leveling implements. Lifting Rod adjustment will have no effect if BOTH front corners of the Rotary Mower drag. If just one side is dragging, yes, Lifting Rod adjustment is in order. (The frozen part is called a Leveling Box. Generic Leveling Boxes are $100 - $150 from on-line venders.)

Do you have an Operator's Manual for your tractor? Should be pretty easy to find on-line, probably free. Here is a LINK:
