Not sure how old your old mower is, but you should be able to get a complete new stamped deck for it. Ive replaced the deck on my 12 yo huskvarna mower 2 times now. They cost about $600.
Most decks are made by same company it seams.
I Wish...
I posted in the 1st thread opener that we have a free cub Cadet i need to pick up , But was completely wrong on that, It is a Coast to Coast MTD with a blown engine. But the deck is Good I am told.
The deck that is flat wore out on our Co-Op MTD Hydrostat (and really isn't the stamped deck itself... )
It is all of the deck drive parts that are shot.
This deck is somewhat unique It utilizes a Timing belt which is cogged on both sides and works much like a cam timing belt on most OHC engines except both sides of the belt are cogged and each side is used to time each of the spindles.
When the blades get out of time they literally hit each other because they overlap and spindles are straight across in the deck. It makes for a great design when working correctly (Blades are
counter rotating and timed to be 90 degrees to each other) ejecting clippings to the rear discharge exit. Belt is about a $100, both spindles are bent and have
The blades have stayed on but pulleys shot, Belt gears both shot, and bearings worn out again. splines shot (stripped) on the primary spindle as well as a damaged taper for the v belt drive pulley . Then there is the stripped spindle threads on the drive pully hold down portion.
No spindles have been available for over a decade and also the cogged belt driven gears either. My Hope is the Junk Coast to coast deck is a more common design that does not require timing and close width wise to the CO-OP hydro mower.
It would have to be shown to me where a like type complete New deck can be purchased for the CO-OP Hydro,
I think it is a 1985 model , so 37 years old.
