SOURCE: Engine runs great, no power at head, drive shafts not broken.

The drive shaft is not seated into position properly or the shaft has broken.

Have you had the shaft off recently? If so, take the shaft off again and try to seat the shaft as you gently pull on the rope. If you need further assistance, just let me know.

SOURCE: remove the trimmer head from shaft

The entire trimmer assembly (from the gearbox forward) will slide off of the drive shaft cover. On the side of the aluminum gearbox assembly, you will find a single screw. This is the "anti-rotation screw" (do not lose this). Then remove the small (approximately 1" diameter) clamp from the end of the gear box assembly and simply pull the entire cutting assembly off of the shaft.

If you just want to remove the trimmer bump head assembly, then you will need to lock the bump head assembly to prevent rotation while you are working. If you purchased this new, then there should be a small metal rod included with your accessories. This will fit in a small hole in the base of the gear box assembly 791-182193 and prevents the trimmer head from rotating.

Then proceed to remove the following items:

791-180814B (replaces 791-180814) Bump Head Knob Assembly
791-147495 Inner Reel (hold the trimmer string)
791-610636B (replaces 791-610636) Spring
791-612026 Retainer (be careful removing this so you do not inadvertently destroy it). If you intend to reuse the trimmer head. If not, then hack, pry, stab, etc.. until you mangle it enough to remove.
791-683301 Outer Spool & Eyelet Assembly should now slide out leaving only 791-612483
Spool Shaft which I will assume that you want to keep.


I replaced my entire string head assembly a couple of years ago (and subsequently misplaced it and am in fact wanting to purchase one) and replaced it with a grass-gater or similar.

I hope this helps.

Hi the key is moulded as part of the flywheel on most machines these days which doesent take much to sheer off , By the sounds of it this may well be your problem.

SOURCE: Cannot disassemble Troy-bilt trimmer head

There is a round, rotary black part between the metal piece to which the cutting head attaches and the outer plastic seat of the cutting head. There are two square slots, each about a quarter inch wide, on opposites sides of the black piece. Slide an Allen wrench or something similar firmly into the slot. Holding the Allen wrench in a stable position, turn the outer plastic ring of the cutting head (it has scalloped edges that can be gripped firmly) counter clockwise to unscrew the cutting head from the bolt on which it is mounted. Be careful with the tool (e.g. Allen wrench) used to hold the black piece steady, as it is plastic and could be damaged by the edge of the tool.

Trimmer head won't rotate


Usually this is a clutch problem, the clutch is under the drum and when it engages turns the drum which turns the drive shaft which turns the trimmer head. If the drum is not turning than it is the clutch, if the clutch is turning the drive shaft could be broke, if the drive shaft is not broke than the problem would be in the gears of the trimmer head.

Check drive shaft. Some models have a flexible cable drive shaft that is prone to breaking. also make sure the drive shaft is engaged in the clutch drum and in the gear head end.

Trimmer runs but the head wont turn


It may be that the drive shaft is broken, or not engaged to the engine. Make sure the trimmer attachment is locked all the way onto the shaft coming from the engine. If it still doesn't work, check by seeing if any of the other attachments work when you put them on. If they do, you know the drive shaft in the trimmer attachment is probably broken.

I bought a new grass trimmer, gardeners choice, it would not start, noticed the end were you put the nylon keeps turning around,some how that shouldn't, .


Your trimmer may not have a centrifugal clutch, and if that is the case, the string head will turn when you pull on the starter rope and it will always rotate with the engine running. The trimmers with the clutch don't engage the drive shaft until RPM's are up to a certain speed and when that speed is achieved, the clutch engages the clutch drum, the flex drive turns and the string head begins spinning.

The trimmer head stopped turning What could be wrong


here is web site for parts

http://www.partstree.com/parts/?lc=husqvarna&mn=225+L+%281994-06%29

almost sounds like the driving drum engagement end has rounded off or the end of drive shaft broke off at either end , or the gear head end is broken / damaged

have a look at the splines on the output shaft on the gear head , check the plate that engages those splines too

physicaly take off the tube / shaft assy from power head and check drum and clutch rotating , check drive shaft end (s)

if ok refit tube / shaft assy ( make sure engaged properly)
tighten mount bolts - remove gear head from end of shaft, start motor and run see if shaft turns ok with some rev s if so
problem is in the gear head

check out website good site


cheers paul hope it helps
