DETAILED DESCRIPTION

[0019] This application provides a stand or fixture for holding a reel mower cutting unit in a stable position for performing maintenance, service or repairs. The improved stand 10 aids mower technicians during repair and maintenance of various manufactured mower cutting units by supporting the cutting unit during such service. As shown in FIG. 7, the stand 10 includes a base frame 12 that is securely attached to a horizontal work bench WB or other work surface. The stand is preferably removably secured to a work bench using fasteners F, as schematically shown, or clamps or other securing techniques. As best shown in FIGS. 1, 4 and 7, the base frame 12 includes two opposite side members 14, and at least two intermediate cross members 16. The side members 14 are preferably 1.5 inch by 1.5 inch angle irons, or may be lengths of steel, bars, tubing or other appropriate metal material, sufficient to support the weight of a mower cutting unit, and are approximately 16 inches in length.

[0020] As shown in FIGS. 1, 4, 5 and 7, three cross members 16 are provided, and are shown interconnected with the side members 14 in spaced and parallel relationship. The cross members 16 are preferably 1.5 inch by 1.5 inch angle irons of approximately 15.5 inches in length, and likewise may be lengths of steel, bar stock, tubing or other appropriate metal material. The ends 17 of the cross members 16 are preferably welded to the side members 14 in the desired positions spaced along the side members. Two vertical riser members 18 are also interconnected with the side members 14, preferably by welding, although drilled holes and fasteners may be used. The riser members 18 are preferably 1 inch by 1 inch square metal tube stock, approximately 6 inches long. The bottom 20 of each riser member 18 is secured preferably by welding at the end of each side member 14, spaced from the cross members 16.

[0021] As shown in FIGS. 1-2 and 5-7, a cradle 24 is provided for engagement with a roller RR, FR of the mower cutting unit. The ends 23 of the cradle 22 are secured by welding W between the tops 21 of each riser member 18. As shown in FIGS. 1-2, the tops 21 of the riser members 18 are configured, shown with a v-shape, to receive a mating configuration of the supported cradle 24. The cradle 24, illustrated as a 1 inch by 1 inch angle iron, preferably of steel or other appropriate metal material sufficient to support the weight of a mower cutting unit, is approximately the same length as the cross members 16, or 15.5 inches. The cradle 24 preferably has a v-shape in cross section for engaging and supporting a roller of the mower cutting unit.

[0022] FIGS. 1, 3-4 and 7 illustrate that the bottom portion 26 of a rear support member 28 is engaged and secured by fasteners F between 2 cross members 16. The rear support member 28 extends upwardly from the base frame 12, such that a top portion 29 of the rear support member is positioned above the cradle 24. As shown, at least 2 of the cross members 16 are drilled with spaced aligned holes 30 through the cross members to enable adjustable attachment of the rear support member 28 via fasteners F at various desired horizontal positions along the cross members. In the illustrated embodiment, left, center and right horizontal positions are permitted, with the rear support member 28 shown in the center horizontal position.

[0023] Once the stand 10 is securely attached to the work bench WB, and the mower cutting unit CU removed from the reel mower, the cutting unit may be positioned on the stand 10 for service with either the front or the rear roller FR, RR of the mower cutting unit resting within the cradle 24. Use of the rear support member 28 enables a surface S of the mower cutting unit on an alternate side from the roller engaged within the cradle, to be leaned against the vertical rear support member. In this position, with the roller resting or sitting, and not moving, in the cradle 24, and the mower cutting unit CU leaned or resting against the rear support member 28, aspects of the underside of the mower cutting unit CU requiring maintenance or repairs may be easily accessed to more safely provide the necessary service, such as front facing or back lapping maintenance tasks.

[0024] To access alternate aspects of the mower cutting unit CU, additional hanging positions may also be used with the stand 10. As shown in FIGS. 1, 3-4 and 7, aligned openings 32 are also provided through the rear support member 28 to engage and secure a support pin or fastener 34 through the rear support member at one of several desired vertical positions. By engaging the support pin 34 at the desired vertical height through the rear support member 28, one end of an adjustable support chain or tether 36 may be suspended, as illustrated. A hook 38 or other attachment mechanism is provided on the other end of the support chain 36 for supporting the mower cutting unit CU. In the illustrated embodiment, the end of the support chain 36 attached to the support pin 34 includes, for example, a heavy duty stainless steel carabineer or hook 40, which may also include a spring biased clip or link. Using a carabineer 40 with a clip, the link of the support chain 36 engaged with the carabineer may be adjusted to shorten or lengthen the support chain between the rear support member and the hook 38, so that the mower cutting unit is suspended in the desired position. In FIGS. 5 and 6, the support chain 36 is extended to a maximum distance. By moving the carabineer 40 to engage a support chain link 42 (or any intermediate support chain link), the support chain 36 is shorter, and the mower cutting unit is rotated up and toward the rear support member in the direction of the arrow of FIG. 6, such that the other areas, for example, a bottom area of the mower cutting unit is more accessible for service.

[0025] With the roller RR, FR resting or sitting in the cradle 24, the mower cutting unit CU can be rotated to a variety of suspended positions from the rear support member 28 by adjusting the adjustable support chain 36. In a “mow” position, the cut of the reel in a “true” or simulated mounted position may be measured. The clearances between the reel and bed knife may be also be adjusted to the desired positions, as well as additional rebuilding or replacement of rollers, reels, reel bearings, bed knifes and bed bars.

[0026] As various changes could be made in the above equipment and process without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying figures shall be interpreted as illustrative and not in a limiting sense.
