Hello Teddy, As far as “pulling the hoses off” this is in reference to the 4n1 bucket. You need to run a couple hydraulic lines to the cylinders mounted on the bucket. If you change buckets you disconnect those 2 auxiliary lines to remove it just like with a grapple.
Your front axle should be strong enough to take the weight of anything your loader will lift… and yes even with a lot of rear weight everything will teeter on the front axle at times…KennyV.
