    i need a husqvarna solution as to how to adjust the speed of the mower in reverse. When you step on the rear pedal to go reverse it is very slow and weak.

  • rfdeitpe Sep 01, 2010

    the belt does not slip.

  • rfdeitpe Sep 01, 2010

    NO, I WILL CHECK/REPLACE OR SPRAY SOME BELT DRESSING ON TO SEE IF IT HELPS. I BELEIVE THE PROBLEM IS IN HOW THE PEDAL MOVES THE LINKAGE AT THE REAR END. LOOKS LIKE NOT MANY PLACES TO ADJUST HOW FAR BACK THE BAR PUSHES THE LEVER ARM, MAY NOT PUSH IT FAR ENOUGH.

    got into problem some more. Belt does not slip, the belt works the same way reverse or froward. The transmission determines the direction the mower moves. There does not appear to be an adjustment in the rod from the pedal and it is not bent. Mower has less than 100 hours no elongated holes. I am beginning to believe the transmission is bad.

Not sure of your system, but some have adjustments on the transmission linkage. Normal reverse speed is 2.4 mph, so it's never going to be as fast as forward gear.
In case you don't have a manual, here's a link for one:

Have u ever replaced the drive belts? that is about the only thing that can cause a slow run is belt slip from worn stretched belts

The one belt drives this tractor in forwards gears most of the time so when the speed of the reverse starts getting slower its time to change the belt. Glaze builds up on these belts causing it to slip in a continuous speed in reverse since that gear is used the least and its an inverted gear other tha forward gears

    if it does not push in far enough it maybe bent or just needs adjustment

Hi,

Many lawn/garden tractors have similar adjustments to the hydrostatic transmissions. On my Simplicity, I followed the rod connecting the forward pedal back to the transmission. That rod has an elongated slot in it, held in place by a 1/2" nut. To adjust, I had to remove the right side tire, loosen the 1/2" nut, and adjust by eye where the stop hit on the side of the case. Too much in one direction gave tremendous forward speed, and little to no reverse speed. Too much in the other direction gave me neck whipping reverse, and NO forward at all. This might be something ya'll can check into.


OR

take to repair shop for warranty inspection. The pump module could be a problem and would be a warrantable repair/replacement for the Authorized Dealer to do.

Not getting gas on my husband 5000 husky he is getting fire. He cleaned the carburator and changed the coil. He gets fire but it ill not stay started.


Use pressure washer for cleaning or washing garden. I take your electricity instead of gas which is much cheaper for us. Before buying a pressure washer pump it is better to read the review about that product. Read review at PressureWasherify

Just had it serviced and it wont start


Ok, let's test it. We need 3 things for a motor to run. Fuel, spark and air/compression.

This first test you always start with as it will eliminatethe need to test for spark and air.

Spray some carburetor cleaner, gum out, into the plug hole

Reinstall the plug

Spraysome into the carburetoras well.

Now give 2 slow pulls, then pull it as u normally would.

If it starts but only runs for a few seconds, you know it's definitelythe carburetor... if that's the case then it needs to be adjustedwith the adjustment needles on the carburetor, which I can help you with as well.

Let me know how you made out

Husqvarna riding mower modle yth20k46 that move very slow


The link rod from the petal to the transmission straightened out at the rear bend. Take it off and bend it slightly further to make it go forward faster. The 1/2" nut above where the rod connects to the transmission is adjustable to set it where it doesn't move when your foot is off the petal. Loosen it a bit and you can move the petal slightly forward or backward to adjust it. Depending on how much you bent the rod it won't take much adjustment. Re-tighten and try it out. It may take a few tries. Good luck!

I have a series 51 husky saw. it starts and runs normally until it gets up to operating temps. then it stalls out and either refuses to restart or just won't restart until it cools down again....


sounds like air fuel mixture screws are out of adjustment..start with the on marked (L)..this is the low speed(idle) adjustment...turn it in all the way just until it stops..but be gentle..then you wnat to turn it out 1 1/2 turns as a starting point..start the engine and adjust it until you get a smooth idle...next, with the saw running, pull the trigger and you should have a smooth response from slow to fast...you can adjust the (H) screw until you get good high speed operation...if these adjustments don't fix the problem thenm yoou may need to have the carb rebuilt( a carb kit is usually only 15-30 dollars)

My husky vt6135 ar compressor when it gets near psi setting it starts to slow down. then it stops, but the motor is sill trying to run and the belts squeel i have to shut it off to keep from burning off...


Loosen the motor mounting bolts and slide the motor away from the compressor to tighten the belts. Proper adjustment is achieved when the belts have about 1/2 to 3/4 inch up/down travel in the middle run of the belt. Tighten the motor mounts before checking tension. Be sure to examine the condition of the belts first. Good luck!

Backfire - Husqvarna YTH20K46


I find my 2148 runs much happier on the medium grade shell than on the cheaper gas. I did have a nasty POW, which resulted in bent pushrods, or perhaps the bent pushrods caused the POW. After replacing the pushrods, and adjusting same, the backfiring stopped altogether. knock on wood. The 21 is a B&S engine which has a propensity to the bent pushrods. Fortunately for me, my neighbor is a wiz at those fine adjustments.

I need to know the carb adjustments for a Husky 65. I need to know how far each screw should be turned out on the carb to get it to run so that I can fine tune the saw.


Start with 1.5 turns on the low speed screw and 1.5 turns on the high speed screw. You can fine tune from this setting.

Hard to start.


My Husky 359 workshop manual says on Appendix A (USA) says "H" 3/4 turn CCW from lightly seated. "L" 1.5 turns CCW from lightly seated.
Page 36 (every other nation on earth) 1 turn CCW from lightly seated for both the "H & L" needles.
There is no recommended initial "T" setting. (from manual) "The idling speed is correctly set when the engine runs smoothly in all positions and there is a clear margin to the speed at which the chain starts to move". I wager your manual would be similar.
These are initial settings and the saw needs to be adjusted for performance. Start with a clean air filter and a fresh fuel mix @ 50:1 per Husky (1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil).

This explains performance carburetor adjustment better than I can:
Carburetor Adjustment by Madsens.com
http://www.madsens1.com/saw%20carb%20tune.htm
CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.

There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.
I hope you found this post helpful.
