Instructions for Setting Up and Operating the


This material is also available from the SFJ Equipment Manual Reprint service. Note, it is written with the assumption that you are the buyer of a new mower which requires some assembly. That not being the case, we feel you will benefit from this material, in this form, if you want to put your New Idea mower to use. Thank you, SFJ

Before starting be sure to put oil in gear case as instructed under item 17.

Cut all wires on the various bundles and lay out all loose parts so they may be readily seen. Thoroughly oil all working parts and the cutting mechanism as you proceed in setting up the mower.

1 and 2. Figs 1 and 2 — Bolt raising lever quadrant and levers to frame attaching lift link to raising lever arm. Use square head counter sunk bolts found in their respective holes in raising lever quadrant. Use washer and cotter on end of stud.

3. Fig. 1 — Place pole in socket, using bolts found in tool box; put flat washers next to nut on underside of pole. Hook of bolt in front end of pole should be up.

NOTE: For proper line-up of the cutter bar the front end of pole should be 32” from the ground.

4. Fig. 1 — Bolt tilt lever and sector to ear on frame with small bolt. Large bolt goes through lever and sector. Be sure to have bushing in lever. Fasten tilt rod to lever and to arm on inner shoe hinge.

5. Fig. 1 — Bolt gag lever to inner shoe. Slide knife in cutter bar; see that it moves freely back and forth; oil all wearing parts thoroughly using a good grade of machine oil.

6. Fig. 1 — Slip grass rod through eye in front of inner shoe and secure with bolt and washer.

7. Figs. 1 & 2 — Remove pin from eccentric bushing in inner shoe hinge; remove bolt from ball portion on inner shoe. Connect shoe to hinge by first slipping the ball on inside of shoe into socket in hinge, then put the pin in rear through shoe, eccentric bushing and hinge; attach gag lever brace to pin before securing with cotters. Replace bolt through ball and socket joint.

8. Figs. 1 & 5 — Attach gag lever links to bell crank as shown, having open side of hook down, and attach turn buckle to top of gag lever.

9. Figs. 1 & 2 — Bolt draft bracket to underside of pole, using the two forward holes of the three holes grouped together. Use clip for hold up rod under nut of forward bolt.

10. Figs. 1 & 2 — Attach draft rod to eye on push bar casting. Hook forward end of draft rod into lowest hole on draft equalizer. Then attach draft equalizer to draft bracket with pin and cotter.

11. Fig. 3 — Bolt seat spring to the socket provided for on the frame.

12. Fig. 3 — Attach hold up rod to top of pole as shown.

13. Fig. 2 — Attach swath board to outer shoe with spring and bolt found in shoe. Spring must be on outside of board as shown. Adjust the nut on bolt until it requires considerable pressure to cause the board to yield. Replace cotter in bolt.

14. Fig. 2 — Bolt grass stick to inside of swath board, placing steel socket over end of stick.

15. Fig. 1 — Pull raising lever to rear notch in quadrant. Hook spring on raising arm and secure rear end with tension bolt to lug on frame. Put sufficient tension on spring so cutter bar will lift easily with foot pedal. It takes approximately 90 pounds to lift the inner shoe off the ground when spring is properly adjusted.

16. Figs. 1 & 5 — The gag lever links should be adjusted so that the outer end of the cutter bar leaves the ground slightly before the inner end starts to raise. This adjustment is made on bolt “B” in Figures 1 & 5. To make the outer end raise faster the bolt should be screwed farther into the bell crank. The turn buckle on gag lever links can be adjusted (lengthening the links) if it is desired to have the outer end of the bar drop lower than the inner end. This adjustment ordinarily is not necessary.

17. Fig. 3 — Remove oil plug in gear case cover and fill with three quarts of light transmission oil SAE No. 90 grade. In cold weather add about one quart of SAE No. 30 oil.

WARNING: The mower is shipped without any oil in the gear case. Be sure that drain plug in gear case is tight.


Pressure fittings are provided on the wheels, the right end of the axle, the crank bearing, and the lift crank on the inner shoe. Lubricate these places once every day. Use nothing but a good grade of lubricant on these bearings. An occasional oiling of the joints of the lifting and tilting devices will materially ease their operation. Wherever the soil is sandy and full of grit the wearing plates and clips on the cutter bar should not be oiled. Where these conditions do not exist, oil the knife and guides frequently.

For proper operation the outer end of the cutter bar should lead the inner end when the machine is not in operation. After long use the cutter bar may lag back and if this happens it can be corrected by making adjustments on the cutter bar eccentric bushing as follows: First making sure that the pin and bolt in the hinge casting “A” Fig. 5 are tight and in good condition. — Set the machine on a level floor and block up the front end of the tongue so that it is 32” above the floor then by referring to Fig. 4 remove retaining pin “B” and with a punch inserted at “C” drive bushing to left until cutter bar lines up as illustrated in Fig. 6.

The cutter bar should be properly lined up before registering the knife. The square head eccentric pin “D” Fig. 5 locates the cutter bar in relation to the sickle. This pin is properly adjusted at the factory and normally should not require any adjustment. Should it become necessary to register the knife, turn pitman so that it is at extreme end of stroke; remove cotter pin at lower of square head pin “D”, pull pin out far enough to turn it. The location of cutter bar can now be changed by turning the pin onequarter or one-half turn to either right or left as required. Secure this adjusting pin with cotter after registering.

Keep the cutting parts in good condition at all times. Always have the knife sharp. See that the tip of each section lies smoothly on the ledger plate to insure a perfect shearing cut.

To remove the lower end of the pitman from the knife head insert the special wrench found in the tool box in the pitman cam as shown at “E” Fig. 5 and push toward the left causing pitman straps to open. The pitman can then be removed from the knife head.


Place the pitman straps on top of the knife head ball; be sure that the flat cam is in the open position. Force the spoons over the ball by pressing them down with your foot, then insert the special wrench in the cam “E” Fig. 5 and push toward the right until the pitman straps are closed and the cam locks into position with an audible click.

Always keep some oil on the ball portion and the cam.

If for some reason the upper end of the pitman needs to be disconnected from the crank bearing, remove only the aluminum dust cap; the blade on the upper end of the pitman can then be stripped off the crank bearing without removing the crank pin nut, see Figure 7.

Do not open-up the crank pin bearing unless it needs replacement. This is a special needle roller bearing and ordinarily needs no attention except greasing.

Use only a good pressure gun grease in this bearing. Under no circumstances use a grease that contains graphite. At the end of the season force in light oils so as to remove all of the old grease.

While a fore truck is ordinarily not necessary on a NEW IDEA mower one can be furnished — as an extra — when desired. Fig. 9 illustrates this fore truck and method of attaching.


Always order repairs by number and give the description of the part, and give the lot number that is stamped on the bottom of the tool box lid, where used and whether it is a right or left part. Right or left parts can be determined by standing back of the machine looking in the direction of travel then parts on the right side are RIGHT HAND and those on the left side are LEFT HAND parts.

A repair catalog No. M-25 was shipped with this machine and was made up for your convenience so proper parts can be ordered if needed. Always order repairs from the NEW IDEA dealer through whom you purchased this machine.
