QUIK-TATCH Weights on Standard Support

Cast iron wheel weights and QUIK-TATCH weights are the preferred form of ballast. Liquid ballast in tires should be avoided if possible since it has a stiffening effect that causes rough ride and makes the tractor more susceptible to power hop. If liquid is used in rear tires, all tires on the axle must be filled to the same level which should not exceed 40% (4 o'clock valve stem position). Specific information on use of liquid ballast is given later in this section.

In some cases it may be necessary or desirable to remove either front or rear ballast. A QUIK-TATCH weight facilitates this for front ballast. Installation and removal of rear weights on outside of wheels require the use of a hoist or forklift. Removal of inner rear wheel weights should not be required after initial installation at factory or dealership.

Standard Front Weight Support

The standard front weight support weighs 170 kg (375 lb).

Independent Link Suspension
   
The standard front weight support mounted on a tractor equipped with Independent Link Suspension effectively ADDS 147% of its weight to the front axle and SUBTRACTS 47% of its weight from the rear axle due to leverage.
   
Front Axle Multiplier = 1.47 Rear Axle Multiplier = -0.47
   
The standard front weight support ADDS 1.47 x 170 kg (375 lb) = 250 kg (551 lb) to the front axle and SUBTRACTS -0.47 x 170 kg (375 lb) = -80 kg (176 lb) from the rear axle.
   
MFWD
   
The standard front weight support mounted on a tractor equipped with MFWD effectively ADDS 145% of its weight to the front axle and SUBTRACTS 45% of its weight from the rear axle due to leverage.
   
Front Axle Multiplier = 1.45 Rear Axle Multiplier = -0.45
   
The standard front weight support ADDS 1.45 x 170 kg (375 lb) = 247 kg (544 lb) to the front axle and SUBTRACTS -0.45 x 170 kg (375 lb) = -77 kg (169 lb) from the rear axle.

QUIK-TATCH Weights

NOTE: Depending on the mounting position used (standard front support or support on front hitch), the effective weight added to the front axle will be greater due to leverage caused by the weight distance in front of the axle.

NOTE: When adding front weights, some weight is transferred from the rear of the tractor to the

front. Use following guidelines to figure tractor weight when front weights are added.

QUIK-TATCH Weights weigh 47 kg (104 lb) each. Up to 22 weights can be installed on the front weight support or on a support on a front hitch. These combinations can be limited by the front axle option.

Weight Transfer Effect of QUIK-TATCH Weights on Standard Front Weight Support

Standard Front Weight Support (Independent Link Suspension)
   
QUIK-TATCH weights mounted on a standard front weight support on an Independent Link Suspension tractor effectively ADD 157% of their weight to front axle and SUBTRACT 57% from rear axle due to leverage.
   
Front axle multiplier = 1.57 Rear axle multiplier = -0.57
   
Each 47 kg (104 lb) QUIK-TATCH weight ADDS 1.57 x 47 kg (104 lb) = 74 kg (163 lb) to the front axle and SUBTRACTS -0.57 x 47 kg (104 lb) = -27 kg (59 lb) from the rear axle.
   
Standard Front Weight Support (MFWD)
   
QUIK-TATCH weights mounted on a standard front weight support on an MFWD tractor effectively ADD 155% of their weight to front axle and SUBTRACT 55% from rear axle due to leverage.
   
Front axle multiplier = 1.55 Rear axle multiplier = -0.55
   
Each 47 kg (104 lb) QUIK-TATCH weight ADDS 1.55 x 47 kg (104 lb) = 73 kg (161 lb) to the front axle and SUBTRACTS -0.55 x 47 kg (104 lb) = 26 kg (57 lb) from the rear axle.
   
Front Weight Support on Front Hitch (Independent Link Suspension)

NOTE: A front hitch is only available on tractors equipped with Independent Link Suspension.
   
Front axle multiplier = 1.69 Rear axle multiplier = -0.69
   
Each 47 kg (104 lb) QUIK-TATCH weight ADDS 1.69 x 47 kg (104 lb) = 80 kg (177 lb) to the front axle and SUBTRACTS -0.69 x 47 kg (104 lb) = 32 kg (71 lb) from the rear axle.

Rear Wheel Weights

Rear wheel weights are available in 75 kg (165 lb), 205 kg (450 lb), and 635 kg (1400 lb) sizes.

Each weight applies total weight to rear axle and none to front axle.

Front Hitch

When tractor has a front hitch, additional front axle and rear axle loads due to its weight must be included in calculating total axle loads. The front and rear axle weights shown in Unballasted Tractor Weight Charts are based on tractors with a front weight support. With a front hitch installed instead of a front weight support the NET amounts of weight changes are used in determining axle loads.
   
NET Weight ADDED to front axle 696 kg (1534 lb)
NET Weight SUBTRACTED from rear axle 216 kg (476 lb)
   

NOTE: The front hitch REMOVES 216 kg (476 lb) from rear axle due to leverage.
