As far as I know there is nothing tied to the radar, but I could be wrong. Have you gone into the commandcenter to adjust the suspension settings? It might not be set on "Auto," which is where I would recommend running it. You can try adjusting it via the instructions below to see if it makes a difference.

Operate Independent-Link Suspension (ILS™) and Cab Suspension (If Equipped)

1. Select Menu.
2. Select Machine Settings tab.
3. Select Suspension icon.
4. Select desired front axle and cab suspension setting.


ILS™ Front Axle Suspension

ILS™ Front Axle Suspension can be set to two different firmness levels and a manual position option: “AUTO” (A), “MAX” (B), and “Manual” (C).

Suspended front axle engages whenever tractor travel speed exceeds 0.5 km/h (0.3 mph). Control after tractor begins moving is delayed. Suspension is active anytime tractor is not in park.
• If “AUTO” (A) is selected, suspension reacts in response to surrounding conditions and events. Provides best possible comfort by looking at inputs such as travel speed, surface characteristics, implement weight, implement usage, and braking activity.
• If “MAX” (B) is selected, suspension is set to maximum hardness (e.g. for operation with front loader). When travel speed exceeds 30 km/h (18 mph), “MAX” setting is deactivated. When travel speed drops below 20 km/h (12 mph), “MAX” setting is reactivated.
• If “Manual” (C) is selected, operator is able to adjust chassis height by pressing Raise button (G) or Lower button (H). Manual setting is overridden when travel speed exceeds 5 km/h (3 mph). When overridden, system returns to previously selected setting (Auto or MAX).


Cab Suspension

IMPORTANT: Cab suspension should never hit end stops. If this occurs, select a stiffer setting

Cab suspension can be set to three different firmness levels: “Auto Soft” (D), “Auto Medium” (E), and “MAX” (F).
• “Auto Soft” (D) enables cab suspension to operate from 0%—100% stiffness. Provides best suspension for transport situations. Cab suspension moves most in this setting. If less cab movement is desired, select stiffer setting.
• “Auto Medium” (E) enables cab suspension to operate from 50%—100% stiffness. Provides best suspension for field operation.
• “MAX” (F) enables cab suspension to always operate at 100% stiffness. Most suitable for loader operations or operations that require frequent shuttle shifting.


Start Up Mode
• Independent-Link Suspension does not move until placed out of park.
• Independent-Link suspension flexes when transmission shift lever is placed in NEUTRAL or any forward or reverse gear.
• If tractor has settled, Independent-Link Suspension may rise about 25 mm (1 in.) seeking to center.
• Automatic leveling is allowed when tractor wheel speed is above 0.5 km/h (0.3 mph).


Independent-Link Suspension in Locked Conditions (Restricted Mode)
• Operator activates hitch raise/lower switch
• Transmission shift lever placed in PARK
• Wheel speed less than 0.5 km/h (0.3 mph)
• Correcting for unlevel condition
• Operator applies both brake pedals


Rear Hitch
• Control units limit suspension response when hitch is raised or lowered with load sense front weight changes
• Depressing clutch and moving transmission shift lever into gear for four seconds and then back to NEUTRAL adjusts suspension toward mid-point. This can be repeated until tractor levels when attaching and detaching implements.


Parking Tractor

IMPORTANT: Prevent possible damage. Do not park tractor with equipment or items under front end of tractor.
• Front end can settle when tractor is parked. Keep front end of tractor away from equipment or other items.
