Model 645 Pedestal Mount Front-End Loader
Quick Mounting and Dismounting
Dual parking stands are integrated with the main frame and provide stable storage while not in use.

Heavy Duty Loader Main Frame
The loader main frame is constructed of 7 gauge high tensile strength steel and incorporates dual torque tubes for maximum frame strength and rigidity even with repeated heavy use.

Mounting Kits and Sub-Frame
Every mounting kit and sub-frame is manufactured to exacting standards with high quality materials and workmanship. Koyker loader mounts and sub-frames will stay tight and secure for the life of the loader, unlike other manufacturer's mounts that wear with heavy usage.

Lift Capacity
Lift capacity varies depending on your tractor's hydraulic system. A standard 645 will handle loads of nearly 4700 pounds to a height of 14' 6". 

Koyker Model 645

Hydraulics
Main frame lift cylinders are 3 1/2" diameter and bucket tilt cylinders are 3" diameter with 1 3/4" diameter Nitro steel shafts (rods) for superior corrosion protection. Hydraulic hose connectors are plated to resist corrosion and have SAE (JIC) 37° flare fittings to eliminate fluid leaks between connections.

Standard 24 Cubic Foot Bucket
The standard 7' wide, 24 cubic foot capacity bucket is a time tested design and manufactured  with an 8' wide by 1/2" thick hardened carbon steel cutting edge to handle tough materials (8' wide buckets are available as optional equipment.) A bucket level indicator is standard on every 645 main frame.
