How do I change blades on a toro 42 in zero turn


Lift front of machine and secure,

Use a pipe wrench over top of blade and against deck, to keep blade from turning,

Use 1/2 " breaker bar to loosen bottom bolt,

Remove blade,

If the bottom bolt doesn't loosen, you may need a wrench at top of deck, above the bottom bolt, to loosen the bottom bolt.

Replace, or sharpen blades, install in reverse order.

GOOD LUCK FRIEND.

Bolt that holds blade well not loosen what is the correct direction to loosen bolt


Remember that on a circular saw, the bolts are typically left-handed thread so it is the opposite of a typical bolt. This is because the blade spins to the right so if a normal bolt was used it would loosen as the saw operates.

19.5hp 42" cut. Shakes when mower is engaged to cut


how hard does it shake? and does it mow?
most lawn tractor will shake a quick almost violent shake at first then it should vibrate quite a bit more while you are mowing this is just caused by the power being pulled from the motor to power not only the drive but the mowing deck. its normal.
if its worse than what i described you may have a bigger problem, if there is excessive clanking from the deck your blade may be loose/installed upside down.

Changing blades.To loosen the blades nut, which way does it turn?


hi. you dont say what make or model but I offer the following. if it's just a single bolt or nut holding the blade it will rely on a bellville type washer (dished ) or will be pegged either side of the nut or bolt, if the later try to drive the pegs down level with the mounting boss, now get a couple of friends to lift the whole deck so you can secure the nut or bolt in a vice (vise) and using both hands turn the blade itself the opposite way that you would turn the nut, this has never failed for me, if the blades counter rotate, one will be left hand thread the other right hand. bear in mind that a rotary blade spins at around 150-200 mph, every time you hit an obstruction (and you will) the blade will tighten particularly if secured with a belleville type washer. best of luck

Changing out the blades...are the attachment bolts reverse thread or normal, i.e. clockwise to tighten?


Should be clockwise to tighten, use some "PB blaster or Deep Creep" penetrating oil on the bolts before trying to take them off. It will help.

Craftsman mandrel replacement::?????HELP


You dont have to drop the deck. Remove the belt first then hold the blade in place so you can loosen the nut on top of the pulley. after you remove the pully then remove the blade. There are 3 bolts holding the mandrel in place remove the bolts. Then pull the mandrel out from underneath the mower deck. There is a shroud that will come loose with it or it may stick from accumilated grass regardless it needs to go back during reassembly. When putting it back together the 3 bolts are usually self tapping into the new aluminum mandrel. Its much easier to put these in and take them out before you install the new mandrel as the bolts cut the threads.

Hope this helps
