New Holland TC-40

[lcfd8]

Hello, I am new to this site... I have just purchased a used NH TC-40 and am not sure of the controls and switches.There is a 2 switches on the right side. One is a 2 position switch and one is a single switch. Can anyone tell me what these are for?? Also there is a switch on the loader control lever... this is for some kind of speed control but does not seem to work. Any help would be appreciated dealer was not a NH dealer.

Randy,
Post this over on the New Holland forum as there are several fellows there who know the TCs inside and out.
Look under the left side operator's deck and get your TC40's model designation (A,DA,S, etc.) and post it. Specifics will get you a quicker accurate answer.
I have a 2002 TC40S but do not have those switches on the right so I can't help. Assuming you are referring to the dash panel, I do have two rocker switches on the left (sitting on the tractor) which control headlights and emergency flashers. Next to and below is a lever switch that controls the R/L turn lights.
Welcome aboard-Good luck-help will come your way.

What you have purchased is not a TC40, but rather a TC40D or TC40DA. The switches you describe are only on those models. Your tractor has an HST transmission, doesn't it?

:welcome: to TBN.!

Here is what the switches are:

1. The switch to the left (forward) on the fender is a Rabbit-Turtle switch. It changes the speed of the HST transmission. If you are in Low range or High range by the lever on the left fender, the switch will select either the high or low speeds of the transmission. The buttons on the joystick do the same thing as the the forward button on the fender. If the fender switch works and the joystick switches do not work, the electrical connector from the joystick might be disconnected. If neither the fender switch nor the joystick work, then you need to look under the left side of the operator's platform for a loos wire going to the speed change solenoid. It's right behind the step for the platform. If that wire is disconnected or broken, you will only have low speed in either Low or High Range.

2. The 2nd switch to the right (aft) is the cruise control switch. When you press that switch, it engages an electromagnet to hold your HST pedal in its current position so you can lift your foot. Stepping on both brake pedals simultaneously will disable cruise. Of course, you can also use the switch to turn cruise off.

I strongly suggest you read posts about your tractor in the New Holland Owning/Operating forum. You also need to get an Operator's Manual for your tractor. You can purchase them online at the New Holland website or through your nearest New Holland dealer. Using your tractor without a manual is not something you want to do. It's VERY important to have that manual so you can operate your tractor properly and safely.

Randy,some questions about your rabbitt/turtle switch not working on the loader joystick.

When you turn the ignition switch to "on". Which lights up,rabbitt or turtle,on your rabbitt/turtle switch on the RH pod top? The turtle should light up. If it goes to the rabbitt without you touching any switches,your button could be stuck on the loader joystick,I have seen it happen many times.

If it lights up the turtle as it should,does the light change when you toggle the switch on the pod top? If it doesn't you will need to remove the LH lower console and check the relays.

If the light toggles,then you need to check the wires going to the speed solenoid. It's under the LH side of the deck,low on the driveline. There should be a black wire and a purple wire connected to it.

not sure witch side is the rabbit or the turtle, hard to see on that switch. I used it today to clean my driveway of snow but it seemed to be in the turtle mode, tractor is not as fast as the JD 970 that I use to have.

Turtle is closest to the operator.
