Planter Effective Weight
Normally a tractor's 3 pt. hitch lift capacity is rated with the
center of gravity (CoG) of the load at 24 inches behind the
lower hitch pins. If the implement has a CoG other than 24
inches, it can 'feel' lighter or heavier. A distance greater
than 24 inches would make the implement 'feel' heavier
and the effective weight would therefore be important to
know so that the tractor is not overloaded and can be
properly ballasted.
Always read and understand the tractor's operator manual
when attaching a 3 pt implements. This information is
suggested to be used as a guide. It is the operator's
responsibility to ensure the tractor and implement are used
safely, both in the field and on the road during transport.
This formula should be used for row crop tractors with a
minimum rated engine power of 200 Hp. If no exact CoG
can be determined for the planter, make an estimate with
some safety factor included.
!! Keep in mind that product weight such as seed or
fertilizer will affect scale weight and CoG. !!
!! Keep in mind that a tractor’s rated lift capacity may be
what it can lift in the field, but is very likely not what it’s
rated to safely carry on the road. !!
EW = SW x D /61 + SWx37/61
EW = Effective Weight ('Feels like' weight) in Lbs.
SW = Scale Weight in Lbs.
D = Center of gravity (CoG) horizontal distance to lower
hitch pins (3pt) in Inches
Example: A 3pt planter fully loaded with product has a
scale weight of 10,000 lbs. and a CoG horizontal distance
of 48 inches to the lower hitch pins. The effective weight
on the tractor would be : 10,000 x 48/61 + 10,000 x 37/61
= 7,868.8 + 6,065.6 = 13,934.4 lbs. Effective weight.
Therefore, the additional CoG distance added about 39%
to the scale weight of the loaded machine
Set the Tractor Wheel Spacing
NOTE: On planters without drawbars, certain tire
combinations require a Category 3N quick coupler
to obtain wheel tread settings on 30 inch rows.
Single Wheels or Inner Dual Wheels Set the wheels
in, as far as possible, with the tread centers between the
planter rows (typically twice the row spacing on non-split
row planters).
Outer Dual Wheels Set the dual wheels with the tread
centers as close as possible between the planter rows
(typically four times the row spacing on non-split row
planters).

Tractor Hydraulics Closed Center Only
Minimum tractor hydraulic pressure - 15 513 kPa (155 bar) (2250 psi)
Working pressure - 20 684 kPa (207 bar) (3000 psi)
Tire Pressures See Tractor Operator's Manual.
Hydraulic Controls See HYDRAULIC CONNECTIONS RECOMMENDATIONS.
a
Dual rear tractor tires are recommended for stability and for load carrying capacity, especially when the machine is folded for transport.
b
To carry the machine for transport, limit liquid or cast wheel weights on rear tractor tires as tire load carrying capacity is decreased.
