 A Keystone steel frame windrow hay loader in the field 
 
 The Right Way to Cure Hay 
 
 Air Curing vs. Sun Drying 
 
 In order to cure hay so that it will bring the best price when put on the market and have the 
 highest possible feeding value, it should be raked into light, fluffy windrows so that the air can 
 circulate through it easily. When handled in this way the moisture is drawn out through the 
 leaves, and the hay is bright, tender and uniform in color and quality. When allowed to cure in 
 the swath the top hay will become dry, losing much of its color and strength, and having little 
 more feeding value than straw, while the hay underneath will retain its moisture and become 
 musty. Another advantage of air curing is that the leaves and heads do not shrivel and break off 
 as they do when the hay is dried in the swath. The best quality of hay can be cured at a 
 minimum expense when it is raked into windrows and loaded with the Keystone steel frame hay 
 loader. Every farmer realizes the value of saving time and labor in the hay field, and the fact 
 that the Keystone steel frame windrow loader does this makes it one of the best investments the 
 farmer can make. 
 
 This loader will handle the heaviest windrows in the gentlest possible manner and deliver the 
 hay onto the wagon without threshing off the leaves and heads. When it is desired to harvest I 
 the crop with all possible speed the hay can be raked into extra large windrows and the Keystone 
 will then pick it up and deliver it onto the wagon in good condition. When the crop is very 
 heavy, this loader will also load hay from the swath. The top of the elevator is made narrower 
 than the bottom so that the hay will be dropped onto the center of the rear end of the wagon 
 where it will not roll off. The Keystone steel frame windrow hay loader is of light draft and 
 very easy to operate, requiring the least amount of help. It leaves the field clean on rough as 
 as well as on smooth ground, and may be worked close to fences, roads and edges of fields.

 The Lightest Draft Hay Loader Made

 Strong Main Wheels and Frame Construction 
 
 The main wheels are strongly constructed of steel. The frame is well put together and is 
 rigid, holding the working parts securely in alignment even in the roughest field and when work- 
 ing with the heaviest hay.

Operating Mechanism 
 
 It would be impos- 
 sible to design a more 
 simple hay loader than 
 the Keystone steel frame 
 windrow. There is not 
 a gear or drive chain on 
 it — the entire mechan- 
 ism consists of a gather- 
 ing drum which gathers 
 the hay and drives the 
 elevator carrier. This 
 loader is of all-steel con- 
 struction and is, there- 
 fore, strong and dur- 
 able. It is, at the same 
 time, light in weight 
 and easy to handle. 
 The gathering drum is 
 ratcheted to both wheels 
 and, consequently, there 
 is no dragging wlien 
 turning corners, and as 
 a result of this construc- 
 tion the gathering drum 
 
 is raised and lowered with the wheels in passing over dead furrows and uneven ground. This 
 makes it possible to gather all the hay irrespective of the condition of the ground. It is never 
 necessary to use more than two horses with the Keystone windrow hay loader. This is due 
 to the fact that it has no gears, pinions, cranks, disks, or other complicated devices which 
 add to the draft of most loaders. There is no question but that it is the lightest draft loader 
 made. The gathering drum is strongly constructed of steel and has eight steel pipe tooth 
 bars to which the spring steel teeth are securely fastened. The elevator carrier is driven by 
 the gathering drum. 
 
 Elevator Carrier Construction 
 
 The elevator carrier is composed of speciall.y selected wood slats held in position on the out- 
 side edges by chains. Several strands of rope run between the slats and keep the hay from falling 
 down. A windbreak is provided, which prevents the hay from being blown from the carrier. 
 This windbreak is very effective and adjusts itself automatically to different conditions of hay.

 Carrier Tightener 
 
 The Keystone steel frame windrow hay loader is equipped with a tightening device near the 
 upper end of the carrier, which permits the proper tension to be kept on the carrier at all times. 
 It is a simple matter to make the adjustments by loosening the lock nut and screwing the threaded 
 rod up or down through the bracket. There is one tightener on each side of the machine so that 
 the top pulleys may be kept in line at all times.

 Clutch Construction 
 
 The gathering drum is ratcheted to both wheels by means of a very simple clutch which can 
 be easily thrown out or in. This permits the loader to be moved from place to place without 
 turning over the whole mechanism, which would make an unnecessary load for the team and 
 which would cause unnecessary wear and tear on the working parts. Ratcheting the drum to 
 both wheels insures even loading on the turns and prevents dragging.

 Teeth 
 
 The teeth are of oil tempered spring steel and are of the coil type. 
 The accompanying illustration shows that two teeth are made from one 
 piece of steel. It also shows the manner in which the teeth are fastened to 
 the tooth bars. This construction insures ample strength for picking up 
 the heaviest hay and, at the same time, gives sufficient flexibility to permit 
 the teeth to pass over obstructions in the field without becoming damaged.

 Forecarriage 
 
 The Keystone steel frame windrow hay loader is equipped with a forecarriage which carries 
 part of the weight of the loader, thus relieving it of the twists and strains which would result if 
 no forecarriage were used. It also makes it unnecessary for the loader to be lifted when being 
 connected to the wagon as the hitch may be moved to any desired position. It permits the driver 
 to disconnect the loader from the wagon without requiring him to get down ofl' the load. When 
 the load is complete he simply has to pull the rope which extends from the hook on the fore- 
 carriage to the top of the load. When disconnected from the wagon the loader is held in an 
 upright position. The loader can be used with any height of farm wagon without readjusting or 
 changing. The wheels on this forecarriage are equipped with shields which prevent the hay 
 from wrapping about the axles.
