Snow removal system for artificial turf and other fragile surfaces
A snow removal system for artificial turf and other fragile surfaces is disclosed. The present invention comprises a tubular metallic pipe or sleeve of a length sufficient to cover the entire blade on a snowplow, having flared or curved-up end components, a channel in which the snowplow blade can be placed, and relatively large-surface-area “footies” to disperse the weight of the snowplow blade and system. The footies can have flared or curved-up edges so that they can glide over the artificial turf surface instead of digging in or otherwise damaging the surface. In other embodiments, the system is used without footies. A means of attaching the device to various snowplows is described as is a recommended method of using the system to remove snow from a surface. It is to be understood that the system can be used on other, relatively fragile surfaces in addition to artificial turf.
This application claims benefit of U.S. Provisional Application No. 61/456,800 entitled “Snow Removal System for Artificial Turf and Other Fragile Surfaces” and filed on Nov. 12, 2010, which is specifically incorporated by reference herein for all that it teaches and discloses.
TECHNICAL FIELDThe invention relates generally to the snow removal industry and more particularly to a snow removal system for artificial turf and other fragile surfaces.
BACKGROUNDThere are many different types of snow removal equipment, from shovels and brooms to very large, vehicle-mounted blades, plows, and blowers. The particular type of equipment chosen to remove snow depends not only on an operator's personal preferences, but also on the effects said equipment will have on the surface from which the snow is to be removed. One surface that has very specialized properties is artificial turf. Artificial turf is a manufactured surface comprising synthetic fibers that are made to resemble natural grass. It has been traditionally used as a replacement field surface for sports that were originally or are normally played on grass. Additionally, artificial turf is now being used on residential lawns and in commercial applications as well.
As the use of artificial turf fields expands into more and more areas that receive substantial amounts of snowfall every year, a significant problem has developed: traditional snow removal devices either damage the artificial turf field or are too time-intensive; or more likely, cause both problems simultaneously. Three means currently employed to remove snow from artificial turf are: (1) a standard, light-truck-mounted snowplow, which can rip or otherwise damage the artificial turf or cause problems with the in-fill (the in-fill comprises small, round, rubber particles that are placed underneath the artificial turf mat); (2) a snow-blower, which can take 8-10 hours to clear a field and have a large potential of damaging the field if they break-down or if they pick up an object in their brushes; and (3) a rubber-bladed snowplow, which “chatters” (i.e., hops up and down) and digs into the field, ripping out small portions of turf fibers and causing significant problems with the in-fill.
Thus, there is a need for a snow removal system for artificial turf that can effectively remove snow in a timely fashion, without damaging the artificial turf surface or the in-fill.
SUMMARYOne embodiment of the present invention comprises a tubular metallic pipe or sleeve (any appropriate material may be used) of a length sufficient to cover the entire blade on a snowplow, having flared or curved-up end components, a channel in which the snowplow blade can be placed, and relatively large-surface-area “footies” to disperse the weight of the snowplow blade and system. The footies can have flared or curved-up edges so that they can glide over the artificial turf surface instead of digging in or otherwise damaging the surface. In other embodiments, the system is used without footies. A means of attaching the device to various snowplows is also described as is a recommended method of using the system to quickly and effectively remove snow from an artificial turf surface. It is to be understood that the system can be used on other, relatively fragile surfaces in addition to artificial turf.
The aforementioned and other features and objects of the present invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following descriptions of a preferred embodiment and other embodiments taken in conjunction with the accompanying drawings, wherein:
Referring now to the accompanying figures,
The sleeve 110 extends the entire length of the snowplow blade 160 and has first and second flare ends 120 and 122. The sleeve 110 can comprise a pipe or other tubular structure and can be made from metal or other resilient material(s) that do not become overly brittle and break under the conditions encountered when plowing snow. Further, the sleeve 110 needs to have a relatively low coefficient of friction as it needs to glide over an artificial turf field without damaging the turf. The first and second footies 140 and 142 help to prevent contact between the sleeve 110 and the turf surface but as field use requirements may necessitate nearly complete snow removal, the footies 140 may need to be removed and the sleeve 110 lowered to be in contact with the artificial turf in some cases.

The step of Installing the Snow Removal System on a Snowplow 571 involves the following: (1) Raise the plow blade; (2) Remove the skids; (3) Align the channel on the sleeve to the cutting edge of the plow blade; (4) Make sure the sleeve is centered on the plow blade; (5) Start at one side of the sleeve and use a floor jack to lift the sleeve, lightly tapping onto plow blade edge; (6) Work down the length of the sleeve until it is firmly seated against the cutting edge of the plow blade; (7) Drill holes through the turf plow bracket and plow mouldboard; (8) Install ½ bolts and locking nuts; (9) Install footies to original skid mounting bolt holes on plow; (10) Adjust footies to desired height using lower nut; (11) Align footies to direction of travel; (12) Tighten nuts to plow and lock the jam nuts; (13) Install safety bolt through top nut and screw of footies; and (14) Tighten lock nuts.
The step of Positioning the Snowplow at One End of the Field in Approximately the Center 572 involves maneuvering the vehicle, plow, and system to one end of the field and positioning it in approximately the center of the field. On subsequent snow removal jobs, be sure to vary the exact starting position so that ruts are not formed in the field surface.
The step of Lowering the Plow and System Until the Weight Is on the Footies 573 involves operating the plow's controls so that the weight of the plow and system is distributed onto the footies (or onto the sleeve if not using the footies). The plow should be set to float and no down pressure should be placed on the plow.
The step of Plowing in Straight Lines Until Windrows Get Too Deep 574 involves plowing the turf field in straight lines and not turning, especially while the plow vehicle is at rest on the field. The vehicle works slowly outwards until the windrows of snow get too deep.
The step of Moving System to Edges of Field and Working Back Inwards 575 involves repositioning the plow and system at the edges of the field (again avoid starting in the same exact position repeatedly in subsequent snow removal episodes as this may create ruts) and then plowing back inwards towards the previously plowed area.
The step of Avoiding Spinning Plow Vehicle's Tires or Braking 576 involves the use of the back pressure caused by the snow impacting the plow to slow the vehicle and plow rather than application of the brakes while on the field. Also, it involves accelerating gradually and not spinning the vehicles tires and thus reducing all extra stresses on the artificial turf field when removing snow therefrom.
Additional use recommendations are as follows:
1. Maximum allowable weight on the field is a ¾ ton pickup truck.
2. Turning must be avoided on the field. A very gradual arc might be allowable under certain circumstances.
3. Avoid braking on the field (let the snow slow down the vehicle).
4. Do not spin the tires.
5. Avoid being parked on the field. If sitting still on the field the vehicle's front wheels must not be turned.
6. Avoid sudden starts or stops.
7. No fluids may leak on the field. Frequently check hydraulics on plow for leaks. Use blue hydraulic fluid as it stands out on snow.
8. Operate plow at speeds under 8 mph.
9. Operate the plow in float mode.
10. Use a long blade (eight feet or more) to minimize the number of passes it takes to clear the field.
11. Change your starting place to avoid creating ruts in the field over the winter season.
12. Use diagonal passes to cut down heavy wind rows.
13. Plow to opposite ends of the field to avoid heavy build up of wind rows at one end of the field.
14. Reverse direction of travel to keep build up of wind rows balanced on both ends of the field.
15. Make several passes across the field to clear the goal posts.
16. Avoid shifting gears on the field and accelerate gently.
17. Use tires having adequate tread depth and slightly decreased tire pressure to avoid spinning out and to increase traction.
18. If running an automatic transmission, stay in LOW instead of DRIVE; for a standard transmission, use high range, low gear.
19. A new cutting edge on the plow to be fitted with the system is recommended to provide adequate support.
