Lockout Valve Installation For John Deere 316(Onan), 318, 322, 330, 332, and 420 Tractors

In this video I install and demo a rear lockout valve for John Deere garden tractors. This valve locks out the rear hydraulic cylinder so that more hydraulic flow is directed to the front ports to improve the operation of a 4-way blade.

thank you....new to this stuff and you show exactly what to do!

[@alvaroeloredo]

Nice, thanks for the video

[@enduser1982]

wow! just what i needed thanks!

[@outdoorpowerhouse]

Mine has worked great during the recent snow we've had. It definitely holds the angle now where before the blade would change angle when pushing heavy weight.

[@maintenanceman1015]

That was close at 4:50 I though for sure you where going to snap that fitting ,the force was with you when
the wrench slipped off . You sound a lot like a guy named Wes that does a great job explaining how thing work. Nice Vid

[@outdoorpowerhouse]

I’m not Wes, but he sounds like a stand up guy. I think maybe it looks like it was tighter than it was, no danger of snapping it off, though I was clumsy and slipped. Thanks for watching.

[@DanLamey-qk7se]

hi so if you close the value the blade angles faster

[@gr8fullfred]

thanks

[@outdoorpowerhouse]

Thanks for watching!

Wow i just can nit rap my brain around how in the hell that works!!!! Lol
And where im really stumped at is Does the differential use the same fluid as what’s listed lifting the attachments.
Thanks for sharing bud
happy new year to ya

[@outdoorpowerhouse]

It works because when the valve is open the flow is shared between the ports for the plow and the hydraulic cylinder that raises and lowers the mower deck, lowering the total available flow to each. When the valve is close it cuts off and the flow to the hydraulic cylinder allowing all flow to be directed to the ports. And yes, it’s the same fluid as the differential. The transaxle pump is the source for all hydraulic pressure and flow on the tractor, including the steering as well.

@@outdoorpowerhouse copy that .. thanks alot!!! Happy new years!!!!

[@mackendw]

is installation of this valve always done at the rockshaft end? could it. be installed anywhere else?

[@outdoorpowerhouse]

This is normally where they’re installed. I think at one time John Deere offered a valve that mounted up near the other hydraulic levers but I’m not sure where it connected.

[@ngzcaz]

Would this be any benefit on a 322 when there is nothing is hooked up to the rear cylinder ? Have a small FEL at present, no plans to use the rear hydraulics..

[@outdoorpowerhouse]

Is your loader using all of the ports on the front of the tractor? One of those shares with the rear cylinder which is the reason to install one of these, so if your loader uses the front ports and you use the existing levers on the tractor there would be a benefit. If the loader’s hydraulics are separate (like a model 44 loader) then there will be no benefit.

[@bryanhoward226]

Do you have a part number for the kit you got?

[@outdoorpowerhouse]

The part number is 318LO from www.auxhyd.com

[@FranconiaFriend]

I'm just learning about the various JD models cited here - actually looking at possibly purchasing a 316 (1991 18HP). Question: is it possible (in any practical sense) to add a second hydraulic port to the front of a 316?

[@outdoorpowerhouse]

It can be done, but it’s sort of pain and involves sourcing the parts, including the steering column, from a 318 from what I understand.

[@FranconiaFriend]

@@outdoorpowerhouse thanks for taking time to reply. After looking at this some more, I think the answer might be "diverter valve"/"hydraulic multiplier". Maybe a bit expensive, but seems fairly straight-forward.

[@outdoorpowerhouse]

Yes you could do that and switch back and forth. It might be a bit cumbersome for something like plowing though it you want be using both lift and angle on a regular basis while plowing.

[@tractorboy31]

​@@outdoorpowerhouse steering column? I would think only valve and handle assembly and steel lines. I just got a 316 and im thinking im gonna do the independent brakes and i was thinking about doing the hydraulics but i the single stage blower is all for the front for now

[@outdoorpowerhouse]

@@tractorboy31 yes, the second set of ports for hydraulics are part of the same system as the power steering.

[@allanmacinnes6429]

You know, if you connect the hydraulics so the lift is on the left. The plow will "float" when plowing and you will do less damage to your asphalt. Oh and you don't need to lock out the rock shaft. Just saying.

[@outdoorpowerhouse]

When hooked up correctly, these tractors already have a float position. I think you’re missing the entire point of a lock out valve.
