Tow Hitch Stability
The MH-400 is very well balanced when empty, or full. The clevis type of tongue on the MH-400 may sometimes bang, and chuck, on the tractor draw bar during transport. A spacer to fill this area in the tongue will work fine. Washers or pipe are too hard and may potentially snap the hitch pin while driving though uneven terrain. Wood is too soft and will not last. An ice hockey puck, with a 1 ¼” hole drilled in the center will work fine as it is firm, yet slightly flexible, and quite inexpensive.

Optimal Spread and Transport Height
While transporting the MH-400 with an option mounted on the back (either Twin Spinner or Cross Conveyor/Swivel Kit). The rear of the MH-400 will need to be raised so as to see approx. 4 – 5 “ of hydraulic ram, so as to ensure these options do not touch the ground.

While topdressing with the MH-400 it is suggested that the rear of the MH-400 be raised so as to see approx. 4 – 5 inches of hydraulic ram. This will ensure a safe transport height, an acceptable spread pattern, good angle for optimal grass penetration as the sand falls. This height is also acceptable to load and transport from the sand pile to the topdressing location.

Hydraulic Pressure
Operation of the tow tractor at an engine rpm of between 2000 rpm and 2500 rpm, will ensure the most efficient operation of the MH-400, supplying optimal hydraulics (pressure and flow)

A tractor auxiliary hydraulic flow of between 10 gpm (35 lpm) and 14 gpm (50 lpm) will ensure the most efficient operation of the MH-400.

The MH-400 operates as an “open center hydraulic flow system”. Therefore hydraulic oil flows from the tractor through the MH-400 and back to return and tank. Operation of the different parts of the MH-400 simply diverts the oil during its flow back to tank. This is a simple, efficient operation that creates very little heat and maintenance. TYCROP ensures correct direction for oil flow by placing a “one way flow valve” in line at the return line hydraulic quick coupler. If you attempt to operate the MH-400 in reverse, by the hydraulic oil flowing backwards, the oil will “dead head” at this “one way flow valve”. You may need to remove the oil and pressure at this valve prior to correct operational direction.

Conveyor Floor Operation
The main conveyor floor maybe operated forwards or backwards, however the designed primary direction is backwards. You may notice slight belt tracking differences when operating the belt in the “forward” direction. This is normal.

Tailgate Removal
Tailgate removal is simple and suggested for transport and hauling of debris and large items.
