Open Question

Drive will not engage

Transmission pin is in correct position. Brake is not on. I have purged the transmission. It appears the drive belt is not activated. What could cause the drive pulley and belt not to spin?

    The mower deck has now been re-installed and the blades turn fine, but the Drive will not engage. Again, the Transmission pin is in correctly and the brake is not on. The #12 Rod Anti Sway is bent and I plan to replace it and it was not installed.



    What could cause the Drive to not engage?



    This LT was purchased in July 2008 and has less than 100 hours.

SOURCE: blades became disengaged -- won't engage

Sometimes the belt can jump off one pulley and cause the problem,follow the belt around all the pulleys and see if it came off one.there may be a belt loosening lever on the lh side of the mower deck, if so unlock it and reroute the belt around the pulley. If you need to replace the belt the manual has a good description on how to do it and should take 30 min with only a couple of tools.

SOURCE: just purchased Husqvarna YTH2348 Purged

As for whining sound I believe this normal. The purging instruction using the bypass valve ingaged on low engine running. Next with the bypass disengaged followed by the fwd with fast breaking and or rev with fast breaking actions to get the wheels to turning and getting better responce takes time. This does take some time to do - in my case 15 minutes or more. My tractor had 65 hours on it before it showed signs of not pulling a slight hill. I had to remove the transaxle and put in 50 wt. motor oil and with the purging I was able to bring new life back to this tractor. The original 30wt. motor oil is fine for a brake in oil and I did drain it and took the bottom cover pan off and cleaned the metal particals on the magnets and cleaned the filter. These transaxle are sealed but have a vent plug at the top of the case. That little plug is hard to get off with out damaging it. My tractor whins in forward and reverse but has good hydrostatic power now. So I say the whin is good!

Recheck your installation. It sounds like you perhaps got the belt on the wrong side of one or more belt guides. If you need an owners manual, post your full model and serial number and I will see if I can locate one for you

I need help putting rear end back together on a 10 hp30 Murray riding lawnmower


Safety and Preparation Serious injury can occur if the engine or mower blades accidentally start while you are working with lawn tractors. To prevent this, drive the Murray lawn tractor onto a flat work surface and disengage the mowing deck cutting blades. Engage the parking brake to keep the mower from moving; chock the wheels with a wooden block or brick. Adjust the mowing deck to the lowest position. Turn off the engine and remove the key from the ignition. While not necessary, you may even wish to disconnect the spark plug wire from the spark plug. Mowing Deck Removal You must remove the mowing deck on a Murray lawn tractor to gain access to the belts. Remove the adjustment rod hairpins, followed by the adjustment rod pins from the front left and right sides of the mowing deck. At the rear on the left and right sides, pull out the retaining hairpins and slide the mowing deck suspension links from the adjuster plates to separate the rear mowing deck from the frame. Remove the blade control rod stud, including the hairpin and washer, from the top of the blade control lever shift linkage at the left rear of the deck. Remove the front hanger rod, including the hairpin and flat washer that hold the rod in place. Loosen the belt guide retaining bolts with a socket wrench and remove the engine stack pulley belt so you can slide the mower deck out from under the tractor Transmission Drive Belt Installation Slide the new transmission drive belt between the engine stack pulley belt guides, over the belt guide plate and under the engine stack pulley. Fit the transmission drive belt around the top engine stack pulley. Push the free end of the transmission drive belt up through the transmission shifter hole in the lawn tractor floorboard. Slip the transmission drive belt loop over the transmission shifter. Pull the transmission drive belt down through the transmission shifter hole. Fit the transmission drive belt around the transmission drive pulley and tighten the transmission drive pulley belt guide retaining bolts to hold it in place. Fit the transmission drive belt flat side around the idler pulley. Slide the idler pulley onto the idler pulley stud while holding the belt in place. Tighten the transmission idler pulley retaining nut with a socket wrench to secure the idler pulley to the idler pulley stud. Mowing Deck Drive Belt Installation Pull back on the right side mowing deck mandrel pulley spring-tensioned belt retainer. Guide the new mowing deck drive belt around the right side mandrel pulley and release the belt retainer. Pull the drive belt spring-tensioned retainer away from the mowing deck idler pulley, guiding the deck drive belt around the idler pulley. Fit the mowing deck drive belt around the left side mandrel pulley and under the rear mowing deck cross link rod between the right and left side mandrel pulley. Slide the mowing deck under the right side lawn tractor frame, reconnecting the deck to the frame in reverse order of removal. Engage and disengage the mower deck while driving the mower to test the belt for proper operation.

Husqvarna 4623 zero turn mower will not move


Maintanance - How to purge Hydraulic drive system Published 01/13/2010 11:56 AM ' Updated 06/02/2015 02:52 PM
How do I purge the hydraulic system?
Hydrostatic transmissions use oil, under pressure, to provide movement for the tractor. The fluid is pressurized with a pump inside the transmission. If any air is in the fluid, the pump will try to pressurize air. This condition is known as cavitation, and is detrimental to the pump since it allows the pump top operate dry. When the pump cavitates it is not pressurizing any fluid, so the transmission is not able to provide the movement needed.
If your mower is new, or has been stored for a long period (longer than 2 months) the transmission needs to be purged before use. Also, if you experience loss of drive, or slower response, then the transmission should be purged first.
The following procedure will remove trapped air inside the transmission(s).
IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.
Step 1- Place the rear of the mower safely onto jackstands on a level surface with engine off and parking brake set.

Step 2- Disengage transmission by placing freewheel control, located at the back of the frame, in the freewheeling position.

2a- Mowers with seperate pumps and wheel motors the freewheel is activated by turnign the bypass valves, one on each pump, two full turns.
The oil resevoir needs to be filled to the specifications listed in the owners manual before starting the purge procedure.
Step 3- Sitting in the operators seat(riders), start engine. After the engine is running, move throttle control to slow position. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 4-Move motion control levers to full forward position and hold for five (5) seconds. Move levers to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times.

NOTE: During this procedure there may be some movement of the drive wheels, but they are not under load. The air is being removed from hydraulic drive system.

Step 5-Move motion control levers to neutral (N) position. Shutoff engine and set parking brake. Check and add oil as needed for units with an oil resevoir.

Step 6-Engage transmission by placing freewheel control into driving position, or by closing the bypass valves on the pumps.
Step 7-Sitting in the operators seat, start engine. After the engine is running, move throttle control to full speed. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.

Step 8-Slowly move motion control levers forward, after the tractor moves approximately five (5) feet, slowly move motion control levers to reverse position.
After the mower moves approximately five (5) feet return the motion control levers to the neutral (N) position. Repeat this procedure with the motion control levers three (3) times.

Step 9-Your mower is now purged and now ready for normal operation.For further information or assistance, we recommend contacting your lo

Why won't my 1998 chrysler cirrus shift into gear?


I'm not familiar with YOUR Chrysler, BUT... my brother' father-in-law had a Buick [about 1998 model] that would NOT shift into any gear UNLESS the brake pedal was FULLY DEPRESSED!!!!!

I could move the shift lever into any of the indicator positions, but the transmission would not engage if my foot was not firmly on the brake pedal while selecting a gear position!

Were do you put hydro drive oil in. I have a 700ex


Hello, sorry to be the bearer of bad news, but the trans-axle on this is a sealed unit and oil cannot be added. The only thing you can do is an air purge or replace the trans-axle.

Doing a purge is really easy:

  1. put transmission in the freewheel mode so you can push it, ensuring that it is on a flat surface
  2. start engine and run full throttle
  3. release clutch brake
  4. push the drive pedal or lever to the full forward position for a ten count
  5. push the drive pedal or lever to the full reverse position for a ten count
  6. repeat steps 4 & 5 three times
  7. depress & lock the clutch brake
  8. return the transmission to the normal mode
  9. drive tractor
If this fails to correct the problem you may need to replace the transaxle.

If you find this helpful please vote yes. Thank You!!

Install belt on toro mower model 70041


For removing/replacing the deck belt, the general method is:
  1. turn off engine, remove key and set parking brake
  2. disengage blade by putting blade engage lever into off (disengaged) position
  3. lower the cutting deck to the lowest position (closest to the ground)
  4. relieve the belt tension (depending on the model, use a 3/8 inch ratchet set to tighten in the square hole of the idler bracket)
  5. remove and replace the belt
NOTE: it's not necessary to completely remove the cutting deck.

Useful diagrams for removing the cutting deck, http://216.213.143.2/ProAuthor/ManProc.cfm?ManualID=425&ProcID=14794

For deck belt diagrams, http://216.213.143.2/ProAuthor/ManProc.cfm?ManualID=425&ProcID=14796

If the transmission drive belt needs to be replaced, several components must be removed and special tools (i.e. air/impact wrench) used in order to change the tractor's transmission drive belt. See an Authorized Toro Service Dealer to have your drive belt replaced.

Craftsman gt 3000 will not drive.


Hi there, On the Craftsman 3000 there is a pin on the back end of the mower that when pulled outward disengages the transmission so it can be moved without it running. Sometimes this pin will stick. It is connected to a lever on the transmission try to push and pull the pin in and out a few times to see if it will free and engage again. You might have to reach under where the lever is connected to the pin rod and try to move it back into position that way. DO NOT REACH IN TO THE TRANSMISSION AREA WITH THE MOWER RUNNING!!! But the pin must be pushed inward for ingagement. This pin will let the mower just sit there like its in nutral and not go anywhere. Try it!!

Rear wheels will not turn. Worked fine when stored for the winter


Craftsman-Husky...same tractors-built in the same factory. I also had a problem with the hydrostatic transmission not providing power to the rear wheels. Here's what Sears told me:
(1) Check to make sure the drive belt is tight both under the engine-and the tranny.
(2) Air can get into the hydrostatic transmissions-especially during shipping (new mower) and storage.
So.....
Pull your freewheel pin out to disengage the tranny-then push the mower both forward and then backwards for 50' or so. Then push the freewheel pin back in and start the mower. If the transmission then works-drive forward-then backward-then forward repeating the cycle about 4 times. Drive about 50' in each direction. This should purge the air from the treansmission.
