Question about Mtd Yard - Man 160cc, 21" Self - Propelled Lawn Mower

1 Answer

I have just bought a Yardman YM 6521 SM self propelled mower secondhand. The lever that controls the gear speed is stuck on 'hare' the fastest speed. Also the lever to control the engine speed doesn't move freely. I don't want to force either as the cables may bend. Help please!

Hi,
Getting the cables loose will require a lot of patience on your part if you do not want to buy new cables...
They can be loosened up most of the time, but you will have to spary a good quality penetrating oil likepb blaster into the top of the cable many times and then let it work... repeat this procedure till the wire inside breaks free of the rust and moves freely again...
Once you have the cable moving, then work a light motor oil like for small appliance motors or at least WD-40 into the wire and down the cable to keep it from rusting again...

The only quick fix is replacement... getting the rust broke free will take time!!

Can I control speed of self propelled mower ?


most self propelled mowers should have a variable speed. the more you squeeze the handle the faster it will go. it is on a spring lever. as some people cant walk as fast as others. some just kick in at a set speed.

Why won't my 22 in. Kohler Low Wheel Variable Speed Self-Propelled Gas Lawn Mower self propel anymore?


i would guess that the belt is'nt tight enough when engaged. when you press the drive bar on the handle it should make the belt really tight if not it will need replaced. sometimes the gears in the wheels will mess up. there are videos on you tube that describe that and also the belt.

Hi I have an mtd yardman ym 6021 sms Self starter, self propelled lawnmower. It starts reluctantly and then runs ok except it runs on full throttle all the time and you have to walk really fast behind it...


your primer is the choke the primer bulb pushes air in ti the bowl then it forces gas to inter the engine to make it start try spraying above the carburetor some wd 40 sounds like your throttle is stuck not letting your governor work ,happens alot

Cable could be stretched belt could be worn or old, if it has a gear box maybe it slipped a gear or lost some teeth. Do some investigation, Good Luck

I bought a Yardman 21" Series 560 self-propelled mower used and the belt was missing. What belt does it take? The manual says 754-04080, but I'm looking for a locally available V-belt. Thank you.


Are you sure the belt part number is not 754-04088?

That is a 33 inch belt. I do not know if you need the 1/2 inch or 3/8 inch wide belt. Pulley size would be the key for belt width. I think it is 1/2. Any local source automotive parts or Lawn Mower supply will have this belt in stock. 1/2 x 33 or 2L 33

If by chance I got the belt part number wrong, (I don't think so) just respond here and we can keep searching for your belt.

Thanks for using Fixya.

Toro 6.5 self propelled Mower - Self Propell won't engage


see if the lever going to the gearbox is cracked or broken. there is a gear inside the box that has a pin going thru the shaft that may have broken but usually it is external. these mowers have a plastic lever to put the transmission lever in gear if the cable is overtightened they wont hold up.if it cracks it leaves practially no tension on the engagment system

Self Propelled mower quit self propelling


you probaly have a broken gear or engagment lever. the part the cable goes through before the cable goes thru the deck. you also could have sheared a pin or the plastic gear that drives it.
