Improve A Mod: Case IH 1455 XL

[MountainFarmer]

The Case IH 1455 XL mod by Oylerhenry, Bauer Hinnark pushes his rear implements too far down. Without 4x4 I cannot seed or cultivate, as the rear tires spin uselessly in the air. I want to try to edit the mod myself to fix the angle of the rear implements, but as I never have edited a vehicle mod I would love some guidance on where to look. I have GE and Notepad++.

[MountainFarmer]

So I have identified this section in ~/caseIH1455.xml

Code: Select all

<attacherJoints comboDuration="2">
        <attacherJoint index="0>5|0|0|0|0" rotationNode="0>5|0|0" rotationNode2="0>5|0|0|0" upperRotation="32 0 0" lowerRotation="-30 0 0" upperDistanceToGround="1.13" 		lowerDistanceToGround="0.34" upperRotationOffset="0.91" moveTime="2.5" ptoOutputNode="0>5|2|0" comboTime="1">
            <bottomArm rotationNode="0>5|0|1" translationNode="0>5|0|1|0" referenceNode="0>5|0|1|0|0" zScale="-1" startRotation="-17 0 0" />
            <topArm baseNode="0>5|0|2" filename="$data/shared/vehicleParts/upperLink.i3d" zScale="-1" />
			<schema position="1 0" rotation="0" invertX="false" />
            <objectChange node="0>5|1|0" visibilityActive="false" visibilityInactive="true" />
        </attacherJoint>
        <!-- trailer attacher -->
        <attacherJoint index="0>5|1|0|0" transNode="0>5|1|0" transNodeMinY="0.719" transNodeMaxY="1.157" transNodeHeight="0.12" jointType="trailer" lowerRotLimit="10 50 50" upperRotRotationOffset="0" allowsJointLimitMovement="false" ptoOutputNode="0>5|2|0" comboTime="1">
            <schema position="1 0" rotation="0" invertX="false" />
			<objectChange node="0>5|1|1" visibilityActive="false"  visibilityInactive="true" />
        </attacherJoint>
        <attacherJoint index="0>5|1|1|0" transNode="0>5|1|1" transNodeMinY="0.4" transNodeMaxY="0.7" jointType="trailerLow" lowerRotLimit="10 50 50" upperRotRotationOffset="0" allowsJointLimitMovement="false" ptoOutputNode="0>5|2|0" comboTime="1">
            <schema position="1 0" rotation="0" invertX="false" />
			<objectChange node="0>5|0|1" rotationActive="35 0 0"  rotationInactive="-17 0 0" />
            <objectChange node="0>5|1|0" visibilityActive="false"  visibilityInactive="true" />
            <steeringBars leftNode="0>5|1|1|1" rightNode="0>5|1|1|2" />
        </attacherJoint>
    </attacherJoints>

Could a experienced modder chime in and confirm that the first attacherJoint node in this excerpt governs the orientation of the rear 3 point hitch? The tractor pushes the rear implements too deep down, namely at the rear end. My guess is that I should reduce the rotation of the attacher? I don't understand the distinction between upper and lower rotation. Do I have to adjust the ...DistanceToGround values?

Thanks in advance!

I'm not a really experienced modder, so I could be totally wrong here, but I would go for what makes the most sense in this part...

Code: Select all

<!-- trailer attacher -->
        <attacherJoint index="0>5|1|0|0" transNode="0>5|1|0" transNodeMinY="0.719" transNodeMaxY="1.157" transNodeHeight="0.12" jointType="trailer" lowerRotLimit="10 50 50" upperRotRotationOffset="0" allowsJointLimitMovement="false" ptoOutputNode="0>5|2|0" comboTime="1">
            <schema position="1 0" rotation="0" invertX="false" />
			<objectChange node="0>5|1|1" visibilityActive="false"  visibilityInactive="true" />
        </attacherJoint>

See this part:
transNodeHeight="0.12

After making a backup of the original mod, I would try changing that 0.12 to a higher value. Otherwise I would try getting a larger tractor like a New Holland T6 or putting a weight in the front to keep the front end from popping up as you describe. If you like I have a John Deere 7030 mod I have altered to have a 400hp and 1000hp option you can try.
It can use a front loader too.
It works best with drive control so it doesn't "rocket" takeoff. Otherwise the with the 1000hp motor it will be kinda squirrely.

It's not that the front axle comes up, so it's not a weight problem. The problem is that the rear implement is pushed down too deep, especially at the rear end, such that the rear end of the rear implement and the front axle have ground contact, while the rear axle of the tractor, in the middle of the whole configuration, is lifted off the ground. But thanks none the less, I will play around with the values in that node and see whether I can fix this.

[MountainFarmer]

The solution was to increase

Code: Select all

lowerRotation

from -32 to 20. Now the implements such as cultivators and seeders lay flat on the ground and slip has been reduced to 10% from 100%.

Nice work. Thanks for posting what you found.
