    Melted and fused bump head "string"

    The "feel" of the string is "pliable" when wrapping, not brittle. The weather here is humid mostly which may have increased longevity. And...as I abuse the string against walls , fencing and dirt the tip of the string is narrowed to perhaps half its diameter of .090," also "curled." (How...

    Melted and fused bump head "string"

    Sorry, did not describe bump head. Do not know models. It is one with knurled round plastic , left hand threaded nut. The wrap direction is shown with an arrow. It has two string outlets of brass which wear out over time. The shaft is a hollow tube with a removable tension spring. I have...

    Just as with the ground drive belt this deck belt a PIA for me. It is in and works well, but (surprise) the owners manual instruction of 3/8 breaker bar to relieve idler pulley tension did not work (for me). The new oem belt is very stiff and with deck in lowered position some slack is lost...

    First replacement of deck (blade) belt . Lots of China replacements on line from $19. Bought $75 oem from same source as ground drive belt previously replaced. Noticed neighbor has Husky mower similar to mine on flatbed haul out. Likely costly repair or even maintenace. I feel for those who...

    The new locker switch is in and working in the rt side coffee cup cavity. It is a simple on-off-on motor switch DPDT, $6, but to use it requires jumpering diagonally across the switch for 12v and ground. It is ac rated which means it may be less "robust" than dc - rated , but not worried...

    Good info...and now more blather...My 'chine cost $3K new which seems down from orig sticker of $5K. The online cost of the locker now ranges $1800-$2000 , with one repair vendor in WI soliciting "freight in" and will quote to repair a unit. What brands besides Husq and Deere use it? At...

    A while back I suspected a problem and looked on line. The smart switch was suspect by many. (I am afraid to state the following) My problem was not the switch. At the time seems like the sw was over $ 200 except for Chinese knock offs (the oem is probably Chinese - They "can" do a good...

    Tuff torq, the tranny mfgr , sells a series of parts and repair kits. One is the slider kit which probably includes the pins and associated slider gear which engages with the "bull gear's" center differential gears and opposite axle shaft. It is around $350 and seems reasonable. There is...

    Well, received wisdom is that it should not need changng. Overly cautious , with too much spare time , went ahead @ 50 hours by pulling tranny, and found only slightly discolored oil. And now, @ 250 hours, failing miserably to diagnose a broken drive belt , went inside and found about what I...

    The belt was rerouted and seems proper, but have not run yet. Now that it has been done 4 or 5 times a few comments ...If no note of the proper belt routing has been made ( as in "pulled out broken") the owners manual is a deficient guide. (1) The diagram of belt installation shows the narrow...

    The mettalic sound was a broken drive belt. The tranny was like new and is installed again. The drive belt is the worst issue ever with this machine . The broken belt was pulled out without noting the routing and this has become a time wasting operation because neither the owners manual or...

    The 6 pin on-off-on rocker (IT-$10) requires an adapter harness bcause the bottomside contacts do not match the female harness plug "amp-packard" (carling). So it is cheaper to buy, but requires a little work. It will control the diff actuator. Also found a Carling VDD1 -6 contact switch ($12)...

    YTH2448 Hydorstatic issues

    I'm about to open my GT 48 locker and have been overdosing on hydrostatic stuff. The internals want clean oil to operate correctly. If gummy or clogged the drive gets slow . There is an oiled plate in there which determines forward and reverse. Not wishing it on you, but with high hours...

    The starter engagement "jamming" has apparently stopped @ 232 hours. As noted earlier it reminded me of British cars I once owned. The sensation was that the starter solenoid was stuck "on" and therefore annoying. The problem can be caused by incorrect engagement of starter drive gear vs...

    Not a reply to seat cover. Over a year ago I attempted to leave info on the failed locker switch which is dash mounted, but it did not show so here is the bare bones info. The switch was damaged by a branch which tore off the (removable) switch top. This switch sends plus or minus current to...

    Another oil temp reading @ 180 hrs: ambient 100F, oil temp 249F. Installed the ebay VDD1 switch and locker is working again. The switch was likely damaged when rocker was ripped off by tree branch.. BTW Carling did respond, but not needed as ebay sw was on order.

    Husqvarna online schematics and the vendor parts lists have not been friendly. The dashboard locker switch does not have a Husq part number on it and pursuit has been tedious.

    Stabil for Gasoline Storage?

    Stabil in whackers, dyt 4000, Husqy rider, and cars that sit too loo long. Never had a clog (I am dooming myself). Purposely use small capacity gas cans to force frequent turnover.. I have often seen advice to fill gas tanks to reduce air , but it always seems counter intuitive, but probably...
