Countax C600h lawn tractor - anybody here knowledgeable?
I've recently "inherited" this ride-on mower - it worked well until
yesterday but now the cutter drive belt tension is suddenly far too slack, despite the tension handle being in the right place. The tension adjusting nuts are on the end of a rod that's anchored on a metal assembly (called a "DECK TENSION CRADLE WELDED ASSY") underneath the front bumper - is this assembly supposed to pivot? |

Not really, I suppose the belt has not worn out.
Some of the drive systems on those tyings are lets just say crude, ie a v belt slipping and tensioned to start to drive the darned thing. Saw on in Geurnsey once and thought, considering the cost what a crude way of doing things, but the was a loooooong time ago now. Brian -- ----- - This newsgroup posting comes to you directly from...

Suddenly, suggests... The cutter belt has either come off one of the pulleys, or there is a pivoting tensioning pulley which has lost its spring for the tensioning. If this is the model I'm thinking of it has three blades and a stupidly complicated drive belt routing. The tensioner is at the front of the deck under the engine area and needs a box spanner or V deep socket to adjust. Mike |

'Suddenly far too slack' implies that the belt has come off one of the pulleys. Some of the pulleys on a Countax can be sods to reach as the belt runs in a most odd layout. I'd try following the belt around very carefully and double checking it is in the vee of *all* the pulleys before looking further. I find with my Honda ride-on that it is always the most inaccessible pulley that has shed the belt... |

'Suddenly far too slack' implies that the belt has come off one of the pulleys. Or that a tensioner has broken, or a spring snapped or broken off. Definite possibilities - and the easiest way to check is to follow the belt around. Judging by the two ride-on mowers I own, they were not designed very well. (I learned to weld just so I could repair the steering on one of them.) Yes, I've done some spot welding on one of mine in the past. An old, Honda engined, Westwood (so under the Honda brandname). It got to the point where I needed to spend some time and effort on it so put it in the shed as a retirement project. Trouble is, now I am retire, I don't have the time to spend on it. Its 30+ years old now so could be close to being enterable in some vintage show somewhere - once I've got it back to proper order. |

pretended : I said "suddenly" because it worked OK and then didn't, but it must have been slack before because nothing has broken, moved or dropped off. The belt slack is supposed to be 12mm and was 75+mm! On investigation, the adjuster was seized (I presume that's why it hadn't been corrected when the previous owner had it "serviced") so I had to dismantle the front end to be able to get a couple of spanners to it. All now fixed and the lawn is done - just need a bit of rain now. It is often easier to drop the cutting deck off the machine and slide it out to make it easier to work on. Thanks. In this case the adjuster is at the front so taking the deck off wouldn't have helped. It looks like a pain to take it off but I'll investigate further when the autumn arrives. |

Judging by the two ride-on mowers I own, they were not designed very well. (I learned to weld just so I could repair the steering on one of them.) It's a simple system, with only 2 pulleys. Now sorted - see below. |

Countax C600h lawn tractor - anybody here knowledgeable?
Harry Bloomfield was thinking very hard :
wrote : Another question. With the cutting height set to 5 the deck wheels are on the ground so I don't see how it's possible to cut any shorter - is there any adjustment on the cutter height setting? Service manuals are usually online and free to download from the manufacturers site. If the deck is not raising itself up at all via the adjustment lever, it seems the linkage might be adrift. You will need the longer cut lengths, for the first cut of the season in spring, until you have the grass under control. http://www.countax.biz/imagestore/ma...%20-%2002).pdf ...might be the one? |

You can lower the deck a little more by adjusting the wheels themselves. Each axle goes through a slot in a metal lug welded to the cutting deck. Loosen the axle nuts, raise each axle in its slot, and tighten again. The cutting deck will be closer to the ground. There are other adjusters, sort of trunnions and things at each corner of the cutting deck support arms, but they are only there to make the deck level. Thanks! I hadn't spotted the three holes for the anti-scalp wheels (this one's got holes rather than slots). Currently the wheel axles are in the lowest hole so that explains why the wheels are in contact with the ground when height 5 is selected. The grass is quite short enough in 5 but it can't be good to have the wheels running all the time so I'll raise the wheels by a hole and see what effect that has. I might also add a physical stop on the height selector so I don't inadvertantly select shorter than 5. |
