You were told correctly. 'Husqvana' tractors for some reason munch up standard vee belts. The belts are rubbish, probably made in China. They only have one Poly-Core to hold them together and there is no re-inforcing webbing in the rubber itself. The rubber is of poor quality and starts cracking after about 12 months even if you only use the mower on public holidays! I had to replace 3 belts in one year @$120 each and now the bearings of the two pulleys of the main drive belt have already flogged out and need replacing together with the drive belt at a cost of $265. Husqvarna machines look nice, but that is about it. Total maintenance cost for two years running (180 hrs) stands at $1,050 (5 belts, 2 pulleys and labour. I'll buy another brand now.because the hydraulic drive has just decided to go dangerously into 'freewheeling' mode (in gear) on the slightest of downhill slopes. Husqvarna is beautiful rubbish..

Hi there,

I have a CTH2542 which has a 42" cutting deck. I bought this from new and it's now aprox 8 mths old. I observed slippage problems with the machine after about 3 months, and being a diesel mechanic myself, dropped the cutting deck off and checked the drive belt. It appeared to be an 'A' section belt which means it should be of 1/2" (12.7mm) section. Measurement revealed it had worn 1mm and was bottoming out on the drive pulley at the motor. Once any vee belt (or pulley for that matter) wears to this point it must be replaced as it WILL NOT grip the sheaves of the pulley. I had my local service agent look at it, but they say they could find nothing wrong. I investigated the problem further and to my surprise, I discovered the swinging (spring loaded) belt tensioner has been positioned on the loaded side of the vee belt. Therefore the more load that's placed on the drive, the more the tensioner is pushed aside, and the looser the drive belt becomes. I have re-jigged the drive setup on my machine (it was suprising easy once I'd figured out what to do). Now, if I **** the bull bar of the machine against my Ford tractor tyre, and load the hydraulic transmission, the rear wheels will actually spin - it wouldn't do that before. The reason I investigated this problem so thoroughly was because I went to buy a replacement vee belt for the machine and was told 'Husqvana tractors for some reason munch up standard vee belts - you must use the genuine belt which is kevlar based'

Need diagram for a poulan xt 30" belt route on deck .Belt keeps breaking shortly after changing I am beginning to think that all the gumballs from the gum trees may breaking it is that possible

Two things first if it just keep breaking..the most probable cause would be the belt on one the spindle or drive pulley " on engine " is routed around most of the pulley then over the belt keeper instead of on the pulley grove..or the keepers are way out of adjustment the keepers have sharp edges on the outside and will tear up a belt in no for the routing most are simple and follow the same procedure,,first look at all the pulleys on the mower deck...there are two kinds the drive and idlers..the drivers are attached to the engine and spindle where the blades and have deep v shape and have on or two belt keepers attached very close on the deck..the others are idlers including the tensioner that engages the belt and keep tension,,they do not have v they are flat with two small right angle edges to keep the belt straight they are designed to ride on the flat back side of the pulley..first detirmine the rotation of the pulleys the starting at the engine drive pulley place the belt in and follow to the first pulley in the direction of mowing all the way around the then operate the engage/disengage lever it will move the engage idler the belt on the flat side the locate others and do the will need to play with it awile but you will find the route...just remember when you do route it look for and adjust the belt keepers..they are there to keep the belt on when running know the results once off the pulley a torn up belt...this is long but i believe if you take your time it will help...good luck.

Some have belt guides. Often they are just metal rods that keep the belt somewhat tight to the pulley. Check these first as you should be able to visually see that they are positioned correctly. Other possible problems would be the wrong belt, a bad (bent) pulley or belt idler, or an incorrectly routed belt.

I have a MTD 0675 g Ride on mower, with a 18hp Briggs IC engine. I have recently re bearing'd the cutter deck and fitted a new belt. I cant work out how to adjust the belt-tighten it a little as it slips...

check to see if the belt is in the correct routing, most belt tensioners are able to be fitted with a factory belt in a couple of different routing methods, however only one is right to keep the belt from slipping, look for a belt routing diagram on the mower deck they are the best source fot this information.

What is the length of the primary mower belt for a Husqvarna GTH2548 lawn tractor

Many of the parts you can just drop the prefix and use the Sears /AYP #
So, look at the hood sticker or in your manual for the Husq#. 532 18 08-08 becomes 180808 which is a common Sears belt for their secondary belt on the newer 48.
OEP shows as a 5/8 X 89"
The primary for these 174368 (Engine to deck)OEP shows 5/8 X 90.
Best to get the oem if you can. Never tried aftermarket on these.
