Kubota owners, this CFKIT filter set is exactly what you need for your MX5400 HST maintenance! This complete kit includes all six essential filters: engine oil filter (replaces HH164-32430), safety air filter (replaces R2401-42280), main air filter (replaces R1401-42270), fuel filter (replaces V0521-51940), hydraulic suction filter (replaces HHTA0-37710), and HST filter (replaces HHTA0-59900). Perfect for the V2403 engine models. The cool thing about CFKIT is they source from top brands like Donaldson, Fleetguard, Baldwin, Sure Filter, HIFI, and WIX - so you're getting quality filters without the dealership price tag. Having all your filters in one kit makes maintenance days so much easier - no more running to multiple stores or forgetting one filter. The quality is legit - these aren't some cheap knockoffs that'll fail prematurely. If you don't see your specific model listed, they'll even create a custom kit for you. Seriously, if you want to keep your Kubota running smoothly without breaking the bank on OEM filters, this kit is the way to go. Much more convenient than buying each filter separately, and you know everything will be compatible. Your tractor will thank you with better performance and longer life!
