Ad does not mention if loader frame brackets, the loader valve, and connecting bars from ROPS to said brackets are included?. Priced listed suggests a close to retail starting point $$.
Ansung markets 3 loaders in this class, that fits many kubota tractors. Includes bucket, grill guard, SSQA, brackets, connecting bars, hardware, warranty, for $3500 +/- plus freight. EA price is more, includes freight. Korean made, warehouse in TX. Almost bought one in 2017. Last minute found out of state kubota dealer that was anxious to move a new loader languishing in inventory. Everything was included.
Price above referenced LA 844 for my MX. This loader is smaller, likely less $$
Note: loader in ad is NOT 4 bar linkage, won't offer roll back and dump angle of kubota CURRENT generation loaders, korean loader is also 4 bar, new standard for tractor loaders.
