Rear wheels not pulling

[Steiner5]

I have been playing around with a B series TC and got it stuck. This is when I found out that only one of the tires on the front axle was spinning. I tried engaging the differential lock and still neither of the rear tires would spin. I checked and it has not thrown any codes. Any ideas????

Thanks...

There is a differential on the front. Does the differential lock work? Does the tractor move in two wheel drive?

Egon,

Yes, I am aware there is a differential on the front also. However, it was my understanding (certainly could be wrong) that the differential lock only applied to the rear axle. The TC moves fine when just driving around. No noticeable problems. You asked "does the tractor move in two wheel drive". I didn't know there was any way to put a TC into two wheel drive. I thought it was always in 4WD.

I do not know if we are talking about a Kubota B series or a Boomer TC. That said, both my 4 WD Kubotas are rear lock only, not front.

I guess I should have been more specific. This is happening to a 2005 B series ToolCat 5600.

Today I did a test. I jacked up the front axle such that neither of the front wheels were touching the ground. Both rear wheels were still on the ground. I started the machine and attempted to gently drive it both forward and backwards. Only the front tires rotated but the machine never moved. So that verified to me that there is very little if any torque being transferred to the rear axle. I also tried this with the differential lock activated and got the same results.

Check your rear CV drive axles, sounds like you snapped one off.
P.S. don't worry about your rear differential or rear drive motor, there working as they should or the machine would be dead in its tracks right where you got stuck.

Ahhh - I was unfamiliar with the type of machine but I see you found a solution!

Sounds like you have an axel issue. Try jacking up front of TC with a jack that rolls. Start the engine and lower the armrest to release the brakes. See if you can push the TC. If you can something has failed in the rear axel. :thumbsup:

On a G series Toolcat, there are 2 transaxles, front/rear, that are driven by a hydraulic motor that is driven by fluid. The TA consists of a bunch of straight-cut reduction gears to a differential center section. Each side axle is driven off each side of this center diff section. Are you getting hyd flow to your transaxle motor? Does the motor function? Are any of the reduction gears broke or stripped of teeth? Is the diff damaged? Is one axle broke or stripped so all of the power is going to the freewheeling side?

First, with the front tires off the ground and the 'cat shut off, can you rotated either front wheel? While holding one wheel, rotate other wheel? Second, I would put the 'cat up on stands and while running and armrest down and in F/R (brakes released), how does the diff and gears feel when rotating the tires?
