Limited slip differential versus Hydrostatic traction control (HTC)

Slummer · Feb 28, 2014

Man, is there ever a lot of confusion over this stuff. Different dealers are saying completely different things.

What is your comment on "differential only working in 2 wheel steer mode"???

From what I have found out about HTC, if you have it on your Toolcat, then you should have a toggle switch on the dash that allows you to turn it off. It turns on automatically when the machine is turned on but then you can turn it off with the switch, not sure why you would do that. The latest Toolcat brochure says that it was available starting in the D series. I spoke to someone yesterday with a 2009 for sale and they said they had HTC on their machine. You're the second person I've seen that have said that the differential only works in 2 wheel steer. We had the demo Toolcat in 4 wheel steer when we were stuck on the side of the road and the differential certainly had no effect at that time. Didn't think of putting it in 2 wheel steer at the time.

You can put the rear wheels at the needed angle, then switch to two wheel steer. The rear wheels will stay at the angle, giving you crab steer to get out of trouble or get close to something.

I set an angle when mowing the dam, feels less likely to rollover.

HTC was introduced September 2013. It can be retrofitted to earlier machines, D & F models.

I just called my local Bobcat dealer and he claims that there is no kit to retrofit earlier models. What is the source of your information?

Dealer is correct, there is no Kit number to order all parts required. My apology if I lead you to think otherwise. Part changes, required to make the retro-fit include; different left front CV/axle shaft, speed sensor, new main frame harness, new cab harness, new pilot manifold block, possibly some hose changes at the manifold block, and a software update. Machines without HTC have a single brake circuit in the manifold block, when brakes are applied it pressurizes all 4 wheels the same.
Given the number of parts required for D series and older F series it is quite costly to make the change over but can be done. F series 5600's starting at serial number A94Y14000 and up already have the needed left CV shaft and both main frame and cab harnesses needed so they would only require the manifold block, speed sensor, and software programing. I was told Bobcat is looking at a kit for these newer machines (built after HTC became optional) so dealers can upgrade if needed, but kit is not out there yet.

SSdoxie: can you tell me if you have to have the toolcat 5600 in 2 wheel steer for the limited slip differential to kick in?

I don't have either one. I just work on them now and then.

Thanks for providing this trlbrkr. This is helpful. Do you happen to have a link to anything describing the previous system in the D-F series?

SSdoxie--I have a 2011 Toocat 5610. Model number APFB1102410072011. The answer I received from a local dealer for this question was "Unfortunately I do not believe we can install the hydraulic traction control. This would require a new wiring harness and the new harness will not be compatible with your machine." This does not seem to gibe with your information. Am I getting a "no" from someone who doesn't want to/know how to say "yes"? Or are they just not willing to research it more thoroughly? Does anyone know of a way to get beyond the dealer and pose a question more directly for a definitive answer from the engineering folks at Bobcat industries itself?
I love my Toolcat--I have dreamed since day one of it being "perfect"--if only it was not such a pig in mud/snow!
