MATERIAL SPREADER
A broadcast spreader, components thereof, and associated methods. The broadcast spreader includes a hopper, a spinner, a motor for turning the spinner, and a material feeder configured to feed granular material from the hopper to the spinner. The broadcast spreader includes a material feeder adjustment actuator, a spinner speed control actuator, and a motor on/off actuator. A harness wearable by a person is configured to carry the broadcast spreader. A kit of interchangeable battery adaptors enables use of different brands or models of batteries.
1 . A broadcast spreader for spreading granular material, the broadcast spreader comprising:
a frame;
a hopper supported by the frame and configured to hold the granular material;
a spinner supported by the frame and configured to turn about a spinning axis for spreading the granular material from the hopper;
a material feeder supported by the frame and configured to feed the granular material from the hopper to the spinner; and
a feed rate actuator supported by the frame, the feed rate actuator configured to adjust the material feeder to change a rate at which the granular material is fed from the hopper to the spinner, the feed rate actuator being rotatable about an actuation axis different from the spinning axis to change the rate at which granular material is fed from the hopper to the spinner.
2 . A broadcast spreader as set forth in claim 1 , further comprising a driver operably connecting the feed rate actuator to the material feeder for adjusting the material feeder to change the rate at which the granular material is fed from the hopper to the spinner.
3 . A broadcast spreader as set forth in claim 1 , wherein the driver comprises at least a first gear.
4 . A broadcast spreader as set forth in claim 3 , wherein the driver comprises a second gear in mesh with the first gear and rotatable responsive to rotation of the first gear.
5 . A broadcast spreader as set forth in claim 3 , wherein the driver includes a rack in mesh with the first gear.
6 . A broadcast spreader as set forth in claim 5 , wherein the material feeder includes a feed gate movable to adjust the material feeder to change the rate at which the granular material is fed from the hopper to the spinner, the rack being operatively connected to the feed gate.
7 . A broadcast spreader as set forth in claim 6 , wherein the rack is movable conjointly with the feed gate.
8 . A broadcast spreader as set forth in claim 1 , wherein the spinner is configured to spread the granular material away from a front side of the spreader, and the feed rate actuator is located on a first lateral side of the spreader.
9 . A broadcast spreader as set forth in claim 8 , further comprising a motor operatively connected to the spinner for turning the spinner, and further comprising an on/off actuator configured to selectively turn the motor on and off, the on/off actuator being located on a second lateral side of the spreader opposing the first lateral side.
10 . A broadcast spreader as set forth in claim 9 , further comprising a spinner speed control actuator separate from the on/off actuator, the spinner speed control actuator configured to be manipulated by the person to adjust operation of the motor to adjust a speed at which the spinner spins.
11 . A broadcast spreader as set forth in claim 1 , wherein the broadcast spreader is configured to be carried by one person during operation of the spreader to spread the granular material.
12 . A broadcast spreader configured to be carried by a person during operation of the spreader to spread granular material, the broadcast spreader comprising:
a hopper configured to hold the granular material;
a spinner configured to turn for spreading the granular material from the hopper;
a material feeder configured to feed the granular material from the hopper to the spinner; and
a motor operatively connected to the spinner to turn the spinner for spreading the granular material;
an on/off actuator configured to selectively turn the motor on and off; and
a spinner speed control actuator separate from the on/off actuator, the spinner speed control actuator configured to be manipulated by hand by the person to adjust operation of the motor to adjust a speed at which the spinner spins.
13 . A broadcast spreader as set forth in claim 12 , wherein the on/off actuator is configured to be manipulated by hand by the person to selectively turn the motor on and off.
14 . A broadcast spreader as set forth in claim 12 , wherein the spinner speed control actuator is configured to be manipulated by the user independent from manipulation of the on/off actuator for controlling the speed at which the spinner spins independently from turning the motor on and off.
15 . A broadcast spreader as set forth in claim 12 , wherein the spinner is configured to spread the granular material away from a front side of the spreader, and the on/off actuator is located on a first lateral side of the spreader.
16 . A broadcast spreader as set forth in claim 15 , wherein the spinner speed control actuator is located on a second lateral side of the spreader opposing the first lateral side.
17 . A broadcast spreader as set forth in claim 16 , further comprising a material feeder adjustment actuator configured to adjust the material feeder to adjust a rate at which the granular material moves from the hopper to the spinner, the material feeder adjustment actuator being located on the second lateral side of the spreader.
18 . A broadcast spreader as set forth in claim 17 , wherein the material feeder adjustment actuator comprises a rotatable dial.
19 . A broadcast spreader system for use by a person to spread granular material, the system comprising:
a broadcast spreader comprising:
a frame;
a hopper supported by the frame and configured to hold the granular material;
a spinner supported by the frame and configured to turn for spreading the granular material from the hopper;
a material feeder supported by the frame and configured to feed the granular material from the hopper to the spinner; and
a first harness connector supported by the frame; and
a harness wearable by the person, the harness including a first shoulder strap and a second shoulder strap, the first and second shoulder straps configured to be received over left and right shoulders, respectively, of the person when the harness is worn by the person, the harness including a front web to which the first and second shoulder straps are operatively connected, the harness including a first spreader connector on the front web configured to form a first releasable connection with the first harness connector for the harness to carry the spreader.
20 . A system as set forth in claim 19 , wherein the broadcast spreader includes a second harness connector supported by the frame, the second harness connector being located above the first harness connector, the harness including a second spreader connector configured to form a releasable connection with the second harness connector above the first releasable connection to stabilize an orientation of the spreader with respect to the harness.
