FarmPro 2425–
I got tired of getting wrenches every time I wanted to adjust my TPH Limit. I decided to make one that didn't need wrenches.
I used 5/16″ x 8″ carriage bolt with 6″ of thread, cut the head off and welded on a piece of 1/8″ x 1″ flat with a 5/16″ hole. The overall length from end to center hole is 9-1/2″.
I used a 5/16″ x 1-1/2″ machine bolt, 5/16″ serrated flanged lock nut, plain washers, lock washer and nut to attach to the control valve lever.
For adjusters I used 5/16″ Ny-Loc Knobnuts from the lawn & garden section of ACE Hardware. These are the knobs used to secure the folding handles on a walk behind lawn mower.
So far I have been very satisfied with the results. I can make precision adjustments as necessary from the seat.
If you decide to make one, verify as you go. This is a first attempt prototype but, so far so good.
I did have to heat and bend the PTO Selector Lever slightly outboard to avoid interference with the adjuster knob.
