Mower Deck compatibility sheet?

[Red_Texan 4]

All,

Am I going crazy or did someone post a deck compatibility chart recently. If I remember correctly it showed different brands/models of decks that would fit with the different WH set-ups. I am looking to find a larger deck for my 310-8 (currently running a 37" side discharge) but don't want to pay the outrageous prices for a WH model.. Additionally , I am curious on the largest deck that would run efficiently on the 310. I have plenty of acres to mow but dont want to go too big for engine. Any thoughts?

Following Along, I've never heard of an aftermarket or different brand of deck fitting a WH.

The exception being a few people have customized some heavy duty zero turn decks.

Biggest I would go on a 310 is a 42”, 48” will physically fit, but the little 10hp would struggle a little bit.

This makes sense, maybe I am going crazy! It is strange that no one attempted to jump into the attach-mattic platform.. I wish I was handy enough to customize one because the prices are insane.

But if you take care of it, it will last forever

Thanks for the info, I was foolishly hoping I could go bigger but even the 42" would be worth the upgrade.

Amen! Maybe I need to start saving!

Absolutely agreed. I ran a 42 side discharge for years with no issue. I have stuck the 48 under there a couple times, and as Karl said the M10 carried it, but it struggled in thicker grass. 

 

A 42 side or rear discharge is a nice match with a 310-8. Very strong and gives a nice cut.

if the $ are an issue then here is a suggestion --- if you are patient and you expand your geographic radius beyond your immediate home town area.... and willing to drive a couple hours, then suggest you look for a 50-75 dollar used worn ugly 42 deck -- either sd or rd --- ( I avoid decks with rust through holes ) then do your own rehab to make it a quality functioning long term solution for your 310 - Yes, they can be hard to find but somewhere an estate, or some eager seller, will be found selling one under market $ value -- then it's your labor time.... and maybe some modest cost for its rehab - - but then you have a deck for another 10-20 years - the spindle bearings are 8-10 dollars -- maybe a new pulley torsion bar is needed, or perhaps a $60 dollar pulley or new belt or blades etc.... but many of those expenses are routine maintenance costs for whatever deck you have now  -- You can clean off rust with power wire brush attachment or use a 90 degree grinder with a sanding disc ---- Or maybe even spend $100 for sand blasting the deck to bare metal to remove the rust before painting - however, i see those "costs" as not as "net" added  expenses but investment in a future tool that lasts for 25-30 mowings per year -  here are a couple before and after rehab photos

added note -- i do not just take and randomly spray over rust with can of red paint like some might do -- i remove belt covers - dissemble deck parts and lift carriage assembly - replace spindle bearings or pulleys as necessary  - new wheels and/or rollers if needed - often replace with new bolts hardware - sometimes new decals, etc

 

Good luck

Want a bigger cut and don't want to buy a bigger tractor or deck.     Buy two 5 HP 20" push mowers and make a 70" wide towing gang mower.

And be sure you have good ear protection!

Wow that looks great! I would absolutely work my way through one but being on the west coast I do not see hardly any available. I am always on ebay with an eye open but am trying to avoid shipping. If I spot a 42" I will definitely make the grab!
