Cee245 846 #1 Posted May 26, 2019 Hi everyone, I have been teaching my son how to mow with our 416h. I will try to upload the video of his first learning experience on our Horse! Cory 20190525_100243.mp4 2 Share this post Link to post Share on other sites
Cee245 846 #2 Posted May 26, 2019 What is that squeaking noise? Share this post Link to post Share on other sites
ZXT 2,401 #3 Posted May 26, 2019 The squeaking sounds too slow to be coming from a belt, and it doesn't sound like a bad bearing on the deck. Possibly the wheels that are on the mower deck? Raise it up where they aren't touching the ground while the deck is on and see if that stops the issue. Does it still do it when the deck is disengaged? Have you greased the front wheels lately?

Cee245 846 #4 Posted May 26, 2019 Pretty sure its coming from the outside deck wheels since it squealed with the deck up and down. Share this post Link to post Share on other sites
dcrage 630 #5 Posted May 26, 2019 Deck wheels on my 37” SD are always the first things to start squeaking after lubrications. Share this post Link to post Share on other sites
EricF 589 #6 Posted May 26, 2019 Main (rear) deck wheels would be my guess, too. They should have grease zerks on them -- they'll quiet down if you put some grease in them and the bearings aren't already too worn out. It's not uncommon to find them neglected by previous owners. The rear (main) deck wheels are the gauge wheels, and they take most of the weight of the deck when it's lowered. Even with routine lubrication, they'll wear out -- possibly sooner than the anti-scalp rollers on the front of the deck, depending on the terrain you mow over. If the tread grooves on them are worn away, it's time to change them -- because they're what determines the height of cut. 2 Share this post Link to post Share on other sites

pfrederi 18,719 #8 Posted May 26, 2019 I agree it is the deck wheels. and i have to wonder why there are no check balls in the zerk fitting on any of them. You pump in some grease pull off the gun and a thin stream of grease shoots out getting on the wheel and the floor. Looked to replace the zerks but they are not screwed in they are some kind of press fit. 3 Share this post Link to post Share on other sites
Cee245 846 #9 Posted May 26, 2019 Thanks for the responses guys... it was infact the outer rear deck wheels. I've greased them in the past but they are both very wobbly and I may just replace with new ones. Cory 1 Share this post Link to post Share on other sites
ZXT 2,401 #10 Posted May 26, 2019 Good to hear! I lost a deck wheel this afternoon when mowing and didn't notice until i got back around to the point where it fell off. Scalped the yard for one pass but oh wheel. Put a new 3/8 nut and a lock washer and I was back in business. By the way, where is the best place to buy deck wheels? One of mine has a large chunk out of it and I wouldn't mind replacing it. Share this post Link to post Share on other sites
EricF 589 #11 Posted May 27, 2019 I just recently bought a set for my 48" deck from RPCW. They carry both OEM Toro ones and aftermarket ones from Stens. The Toro ones cost more, but qualified for free shipping, which brought the total bill down versus the Stens ones which would have shipping costs added. I can confirm the Toro ones have pressed-in zerks, with no check valve. There are applications for zerks like this -- usually where grease has to fill a tightly-sealed cavity which could over-pressurize and lock up if the grease can't escape anywhere else. The intent on the deck wheels is probably to just let the grease in and out freely, since the wheels run in the dirtiest location possible. The grease will get contaminated no matter what. The engineers probably thought it was better to replace it more often than what happens in applications which retain the grease with the check valve. If the grease only backs up through the zerk and won't flow into the bearing and onto the axle, then there's probably caked-up gunk and hardened grease in the passage... time to change the wheels. Think of them like tires -- they last a while, but they're still an expendable part. 2 Share this post Link to post Share on other sites
