Here's the parts manual.
This should help.
The deck will need to be supported by 2x4 or 4x4. You will need some slack in the chain deck hangers. Remove the chains at the attachment points.
You may be able to replace the spindles without removing the deck...
Try lowering the air pressure in the tires and then adjust the level of your deck.
Try 10 psi in the rear and 12 psi in the front. That will give you less bounce.
Ingenuity.
Do you realize that the mower deck is not supposed to ride on the anti-scalp (gage) wheels?
Are you cutting the entire 4 acres with that mower?
I have 3 acres to cut and it's pretty bumpy. I use a commercial 60" zero turn mower. I cut at 2.5" to 3" depending on growing conditions...
I've experienced the U1 batteries being a little low. I check mine on a regular basis. There is usually electrolyte covering the lead. Those little YUASA batteries in motorcycles and ATVs are a different story.
FYI: The gage wheels are not supposed to have continuous contact with the ground. If you are cutting at 3" or less, move the wheels to the top mounting holes. For anything over 3" move them to the lowest mounting holes.
The Rotary blades are cheaper than the factory blades and they will cut just as well or better. They sharpen up nicely too.
Gators are okay late in the season and the first and second mowing. When the grass has fully greened up and filled in, the high lifts work best.
FRAM filters and Autolite were once part of Honeywell Automotive. FRAM has always made their own filters.
As far as the OPE and engine manufacturers, they DO NOT make their own filters. Like you said, they contract that out to the lowest bidder.
OE filters are usually of lower quality and cost more. They are often the entry level or jobber filters. OE filters are made by major manufacturers and painted a different color. You are correct about buying from Ebay or Amazon. When buying from Ebay or Amazon, one must check the seller...
Exactly! Microgard Select, from O'Reilly Auto Parts, and NAPA Gold are sourced from either China or Vietnam. NAPA dropped WIX as a supplier because the quality dropped off.
The belts themselves aren't the problem. Other issues are causing the belts to fail..The deck needs to be checked for damage. The pulleys, idlers, spindles, bushings, and tension springs need to be checked. The pulley alignment is way off.
If you look at the picture carefully, you will see the problem. You have pulley alignment problems. I suggest getting the deck out from under the tractor and give it a good going over.
