Want this question answered?
I know only the simple machines in a lawn mower. Wedge, lever, wheel and axle, and screw.
Yes a lawn mower is a compound machine. Example: The wheel is a wheel and axle.
That will depends on the manufacturer and model of transaxle that is under the mower.
You have to buy the whole axle....cost about $486 on line from Coleman Equipment they do not sell individual parts. Kubota knows that these axles are only good for about 400 hours. this is some of the first junk that Kubota has made. Most of their stuff is good for at lease 2000 hours. Sad but true, the rear u joints can be bought on Ebay at about half price.
As long as you are mechanically inclined, and have a good place to work and some good tools, buy yourself a M4700 Service Manual from your Kubota dealer, and have at it. If not, then I'd recommend taking it to an Agricultural Service Shop or a Kubota dealer and having it fixed. Good luck!
A mower may start to steer hard from many things: -Flat/soft tires -Lack of grease on the front axle or front axle joints -Lack of grease on the rack/pinion gears -Lack of grease on the steering wheel bearing -Crack in the axle itself, allowing the corners of the axle to move I have had all of these happen to me and they are relatively quick to rule out.
you probably need a pair of snap ring pliers
you would have to get another transimishon for the front and a axle like the back
yes
A compound machine is a machine made up of two or more simple machines. So a lawn mower, push or riding, has Wheel and axle set ups, levers for the throttle and mower blade. That's why it's a compound machine.
You should use 80 to 90 wt oil.
look for a nut or cotter pin on the axle, where wheel goes onto shaft,
