How can tractors be immobilised

Post by jonmar » Wed Dec 19, 2012 10:57 pm

I want to disable my 1390 from casual toerags.
Removing the battery is not practical, has anyone any suggestions?

It needs to be use able but secure.

Glad you got your tractor back Jon. A battery isolator switch is a good place to start, won't stop them but will slow them down. Maybe an inline tap hidden on fuel line somewhere would be an idea. Tracker offer a model for plant and machinery thats not a fortune also.

P.s. big nasty dog left in cab might be another idea!!! :lol:

Take a look at this. This unit has been developed over the last 3 years and works so well that those European tractor manufacturers that it has been demonstrated to want the patent and are fighting over it, but that's not going to happen. Will work on other vehicles also.

Disconnect the fuel shut off linkage at the injector pump.

Hidden kill switch in the battery cable.

I take it we have no link up or interest at all in this fine product from Vapourmatic ???

Just out of imterest how deos an all singing all dancing keypad immobolisation system overcome the issues of a mechanical fuel pump and mechanical fuel stop that can be got running with a tow.

Cheers

It can not...

For cars, there are bulky mechanical locks which you place over the gearselector when it is in neutral.
In combination with an isolator swich, it will be hard to start the tractor.
Towing is still an option then, however, no powersteering

**Edit: just remember about a tubular locking device which I've seen online, which is placed over the cylinderrod from the powersteering. Fully steer to the side where the rod is extended the most and then fit the locking device.
The lock itself is integrated in the tube, and hard to cut, has to be drilled out..

I know of a company who have a very similar product. You are right Andy, It will only work on more modern machines with electronic fueling etc.

As for immobilising older things, such as our DB's, its not easily done, baddies with basic mechanical knowledge can get the things going very quickly. Take bits off, hide bits, add bits, block it in with other bits, unfortunately all you are doing is delaying them, not stopping them. :(

Jon, really glad that you got your 1390 back, if I were you, hide it well, as well as any other valuables you may have on the site, its sad but true that you may now have made them angry and they will be back later to try again or cause more damage.

Good luck.

:)

Indeed Emyr, if they want it, they'll have it anyhow :-(.

If you can slow them down a lot it will help and if they have to make much noise etc. they don't like that :-)

I have trusted on a heavy chain and padlock with my mororbikes. The chain must be heavy and hard so that metal saw does not cut it. If you find a way to use the chain to lock front wheels to fully turned position it is impossible to transport the tractor without tow car or other special equipment. Not every clown takes an aggregat and angle grinder to their toolbox them when going to work. I cant remember if it is possible to lock parking brake by a chain. That would prevent towing by a tow car.

There are some things you can do. Sadly the keypad that PR linked to won't work on these things - it's a bit pointless when a screwdriver across the starter will bypass it!

I found on my DB that when you turn the steering in the full lock the track rod goes close to the axle at one side (the opposite side for the opposite lock). This allows you to wrap a strong chain round with a heavy padlock (where the rod is at its closest to the axle), and it does stop the steering from straightening.
I intend to weld on two pieces of flat plate top and bottom of the axle, allowing a pin to go through with a padlock on the bottom in such a way that it would be very hard to get a hacksaw at it. If the steering can't be turned then stealing it becomes much harder.

The next place I'd look would be to lock down the brake pedal - can you make a bracket or chain that will take a padlock? Again that makes it very hard to steal.

Fitting an isolator is not a bad idea, but I take the view that tractor thieves are likely to know as much as you about simple mechanical/electrical things, and when they get no power through they'll just follow the battery leads or connect a jumper battery. They'll probably know to look at the stop linkage on the injector pump and anything else you can think of.

You've got to make essential things such as brakes and steering impossible, and try to make it so the lock can't easily be cut, and where it's hard to dismantle whatever they work on. Thieves can be quite cunning.

One very simple deterent to stop a tractor being stolen, remove the steering wheel.

A pair of locking pliers on the shank would handle that easily.

A pin through the timing hole into the recess in the flywheel? Properly done it would look like any other bolt in the frame.

I already wrote that motorbike is sort of risk to keep outdoors in certain countries. It is too easy to walk away even if the engine is not running. I have heard about a case when a team of Harley riders stopped for coffee pause on a highway. While they were sittig in and enjoyed their refrehsments, one of the bikes disappeared, even if the front fork was locked. They supposed that there must have been a lorry and a crane or a van and at least two bulky lads to get it in. With bikes its vital to tie them to a solid object, a light post etc..
A tractor is easier to secure, but still its important to prevent towing.
