Hi Al, is this a gas or Diesel 434? If it is a Diesel then it probably only has the start switch connected to the S terminal. I have seen the other terminal used on a gas engine to supply 12V to the ignition system for starting and then when the key is release from start to run the ignition system is fed thru a dropping resistor. Does this tractor have a safety switch on the clutch? The 434 that we owned did not but it was an early 434, I know the 384 we had had a starter safety switch on the clutch. The clutch had to be depressed before the starter would engage. This switch caused a lot of problems and most farmers eliminated this safety device. Now to trouble shoot your start problem with a jumper cable.
BEFORE ATTEMPTING THIS MAKE SURE TRACTOR IS IN NEUTRAL AND REAR BRAKES ARE LOCKED ON AND FUEL CONTROL ROD IS IN THE OFF POSITION.
Test 1:
Now take a single jumper cable and connect one end to the big terminal on the starter solenoid that has the cable from the battery (top terminal), now monentary touch the other end of the jumper cable to the bottom big terminal that is connected to the starter motor, the starter motor should spin but not engage into the ring gear. If it does not spin then there is the following possibilities:
1)Bad connection to battery or battery to ground.
2)Bad starter or starter to ground connection. As I rememember the ground connection to these starters was thru the front end bearing which was not good and later models had a separate ground strap from bottom terminal at the from end of starter to engine block. If test 1 works then test 2 is same connection as test 1 but this time monentaryly touch the jumper cable to the S terminal on the solenoid.
This time the starter motor should spin and engage in the ring gear. If the starter motor does not spin and engage the ring gear then either the solenoid is bad or the ground on the solenoid is bad. If test 1 and 2 work then the problem is farther back in the start switch circuit or safety switch or fuse in the start switch line. Hope this helps

Choosin, Mounting and Using a Bush Hog Type Mower - by Francis Robinson. Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
