south africa | My TW35 don't want to make a right turn, and when I try brake steering with right brake, it stops the whole tractor!!
The difflock seems to work fine, what could be wrong |

Alma NE | Does it do it in high and lo on the dual power .
Maybe there is an internal oil leak on the brake side .
The low pressure oil pump supplies the dual power , brakes,pto and the dif lock
If the brake is leaking it could be loosing oil pressure and letting the dual power slip .

Alma NE | Yes I read it as it stops the whole tractor I'm not sure if the poster means kills it or stops it moving , so I'm kinda just guessing he means stopping it from moving . |

Alma NE | Either way the more helpful answeres the merrier right . |

south africa | Hi guys, thanks for your replies. English is not my first language so pardon my poor explanation!
when I turn to the right(front wheels turned), the tractor keeps going straight
if I then try to turn it with the right brake, it wants to kill the engine as if I'm braking both brakes
it does it in both setting of duel power, and duel power is not slipping
the tractor do lose brake, clutch and pto function for a few seconds when I drive a steep slope with the left wheels to the top

southern MN | I thought he is saying his differential lock appears to be locked up, and the tractor will not turn.
If he turns the front wheels they skid, and if he puts one brake on it lugs (not kills exactly, but lugs down) the tractor, still won't turn as one would expect when one brake is applied.

south africa | Paul, you are spot on, except that this only happens when turning right. If I turn left everything works as it should.
I don't know how the diff lock works, but it seems as if the left side of the diff lock stays engaged , if that is possible ?
In my previous post I said I lose clutch function to, when driving on a slope,that is false. As far as I can see it loses brake, pto and duel power. The tractor and pto stops for a few seconds (with the engine running normal and no brakes) and then it suddenly starts moving again.
Could this have any connection with the turning problem ?? |

Madison Co. Virginia | I'm late replying, but...
Our tw25 has the same problem yours does about losing pressure on the side of a hill. The direction of lean is the same as yours, also. I've never gotten a satisfactory explanation, but I suspect that the oil pickup tube has a leak near the top, so it readily loses prime when the oil sloshes around in the transmission. This is just my thinking-- I've never heard this from anyone more knowledgeable. The pickup tube is bolted inside the rear axle housing, and connects to the pump which is in the transmission housing, so I think there would be plenty of opportunity for leaks. It would mean a rear axle/transmission split to investigate though, and I haven't bothered.
On the brake/diff lock problem, it sounds like the diff lock is staying on all the time, but it doesn't make sense why it allows you to turn one way but not the other. The problem is probably in the power brake valve or the diff lock valve. Locate a dealer service manual(not the IT version), and study that for ideas. I see several tw-x5 manuals on eBay for $100. Some places that reproduce old manuals may sell you one for cheaper. |

south africa | thanks kipps, have you seen where that pipe is fitted to the axle housing and more important, where does it end?
if it ends in the left hand corner, could it actually suck air as the oil level drops on that side, on a hill?? a mechanic told me the other day to keep the oil level over full, and it kind of helps!!!
about the brakes, the diff lock is not stuck permanently, but could it somehow engage when I push the right brake only??
thank for your time

Madison Co. Virginia | I've never split the tractor. I'm not a mechanic, I'm just too cheap to pay one, so I tinker with what I get around to, and just speculate on the rest.
In the brakes/diff lock, it would sound possible, but I don't really know. A casual glance at the manual gave relatively little detail about the inside of the brake valve. My tw25 has a completely different braking system from the 35, with no possible correlation between the diff lock and the brakes. But your tractor does have some connection between the two. |

south africa | Haha, looks like I discovered my twin brother( in thinking anyway), on older tractors like these spare parts are already expensive so paying a mechanic is wild.
me and my brothers do most of the fixing ourselves, and it always help to know in advance if it is feasible |

south africa | When I push down on the right brake, both left and right brakes engage, so I recon the left brake is dragging when just driving, to.
