Ballast Recommendations

Additional ballast not allowed if tractor is equipped with hitch, or hitch and PTO.

Do not operate tractor at weight exceeding maximum ballasted weight of 28122 kg (62000 lb). Warranty may be voided due to “overload” conditions. Reduce load if unable to obtain correct ballast without exceeding maximum ballasted weight.

To extend drivetrain and track life, avoid excessive soil compaction, and reduce rolling resistance: avoid excessive ballast. Never add ballast that results in operating with heavy loads and with continuous full-power below 6.6 km/h (4.1 mph).

For 9RX Narrow tractor, avoid operation with continuous full-power loads below 7.5 km/h (4.7 mph).

Do not operate tractor with:

• Extreme draft loads requiring two tractors hooked in tandem.
• Tow hooks. Adding tow hooks is not an option.

Optional front axle reinforcements and frame supports are required when mounting front sprayer tanks or dozer blade. (Dozer blade not approved for 9RX Narrow tractors.) See your John Deere dealer for complete mounting instructions.

For front spray tanks:

• Do not exceed 1136 L (300 gal) capacity on each side.
• Intended for spray or fertilizer application purposes only, not for extra ballast.

Use only as much ballast as necessary. Adjust ballast as tractor use changes. Correct ballast allows for most efficient use of available power to tractor but cannot make up for an implement which is too big for tractor.

Adding ballast cannot overcome incorrect engine speed settings. For correct ballast, measure amount of track slip. See Measure Track Slip in this section of this Operator’s Manual.

Ballast Options

Equipment configuration determines maximum quantity of Quik-Tatch™ weights. A maximum of eighteen 43 kg (95 lb) Quik-Tatch™ weights can be added to rear of tractor as long as maximum ballasted weight does not exceed 28122 kg (62000 lb). See Quik-Tatch™ Weight Use in this section of this Operator’s Manual.
