Kubota makes kits for alot of there tractors, but they can be pricey, BUT they are fairly easy to install if you have good mechanical skills . Kit should have good instructions. I did my freinds L3830 GST 4 months ago , took about 2 1/2 hours, taking my time. Did my B7800 5 years ago, took a little longer. Your L4330 should be fairly easy. But look to pay $850 to $1350 for kit alone . Shop around so online dealers may charge $50 to $100 less. Good luck. Steven.:thumbsup:
Dealer installed remotes are very expensive, probably >$1K for dual remotes.
I was fortunate that my Mahindra dealer offered triple remotes for $700 (for my 2008 Mahindra 5525). Can't pass up a deal like that.
If you want to DIY and save some $$$, check the Hydraulic forum on TBN. There's a lot of good info on how to do it. You can get all the parts you need from Surplus Center (which advertises here on TBN).
I ordered a Kubota remote kit from Barlow in KY. I tried to spend money with the local dealer, but after 2 weeks it still wasn't ordered so I went this route. It was over $100 less and I had it in 3 days.
