Subject: (ET) E20 Foot Throttle Pot Problem - Ideas
Date: Sat, 23 Oct 2004 22:28:44 -0400
The problem with using a foot throttle with a DCX 300 controller is
from the tractor bouncing, or your foot bouncing even on smooth ground.
The original foot controller on the E20 had a heavy return spring and an
adjustable drag built into it. It also had only eight speeds so it wasn't
affected by small movements.
The pot assembly that is an option with the Alltrax is very sensitive
to small movements. Its spring is weak and that causes the weight of the
foot pedal to move the pot setting when the tractor bounces. A heavy
spring added under the foot pedal will help some. If you can remove the
microswitches from the original controller and hook a cable from your pot
down to the slide inside the old throttle box, you can adjust the spring
and drag to elliminate some of the bounce.
Mounting a throttle on the steering column or dash should stop all
bounce problems. A foot throttle and a dash throuttle cruise control
worked best for me, since I already had the foot throttle installed and it
bounced. And I thought a cruise control would be neat anyway.
