Attaining Optimum Performance
Before
adding ballast to your tractor, consider these important factors to attain optimum performance:
-
Total tractor weight and static weight split (percent of static weight on front and rear)
-
Type of operation
-
Type of tractor and implement setup
Recommended Weight Split
Tractor should be weighed to accurately determine amount and type of ballast. Weight should be distributed depending on how tractor is equipped and the conditions in which it will be operated.
NOTE:
Ideal weight split is 55 percent front
1
, 45 percent rear, of total tractor weight for towed implements; 60 percent front, 40 percent rear, of total tractor weight for hitch mounted implements.
Correct Ballast
Use no more ballast than necessary, and adjust ballast as tractor use changes.
For correct ballast, measure amount of travel reduction ( % slip) of the track. Under normal field conditions, travel reduction should be 2-5 percent. Add more weight to tractor if slip is excessive. If there is less than minimum percent slip, ballast should be removed, unless needed for stability.
Correct ballast allows for most efficient use of tractor's available power but will not make up for an implement
|
which is too big for the tractor. Adding ballast will not improve performance, if engine speed falls below rated speed and/or track slip is not beyond the recommended range.
Selecting Ballast Carefully
| Factors Determining Amount of Ballast |
| |
| Soil surface-loose or firm |
| Type of implement-integral/semi-integral or towed |
| Travel speed-slow or fast |
| Tractor power output-partial or full load |
| Track-size |
Pulling a lighter load at a higher speed is more economical and more efficient than pulling heavier loads at a lower speed.
| Too Little Ballast |
Too Much Ballast |
| |

| Excessive slip |
Soil compaction |
| Power loss |

| Track wear |
Increased load |
| Fuel waste |

| Lower productivity |

Ballast Limitations
IMPORTANT:
Tractor weight exceeding heavy ballast limits should be avoided and may void the warranty due to "overload" conditions.
Ballast should be limited to a maximum of 22680 kg (50000 lb) for satisfactory power-train life; this weight limit includes any added ballast.
