## Abstract

An infeed chute for a material application machine includes a riser and a water spreading unit. The riser includes a sidewall and defines an infeed opening extending through the riser. The riser is configured to be coupled to an opening of a tank of a material application machine such that application material passed through the infeed opening of the riser enters the tank of the material application machine. The sidewall includes a water inlet formed therein. The water spreading unit is coupled to the water inlet and is configured to direct water laterally across the infeed chute.

## Claims

### Claim 1

A hydroseeder comprising:
a tank comprising an opening and configured to hold a material slurry;
an infeed chute comprising a riser coupled to the opening of the tank above a plurality of grinding flights positioned within the tank; and
a water inlet incorporated into a sidewall of the riser of the infeed chute, and configured to direct water laterally across the infeed chute.

### Claim 2 (depends on 1)

The infeed chute of claim 1, wherein the water inlet comprises a water spreading unit, the water spreading unit comprising:
a water spreading housing coupled to the water inlet of the sidewall of the riser; and
a tongue coupled to the water spreading housing and extending the water inlet of the riser.

### Claim 3 (depends on 2)

The hydroseeder of claim 2, wherein the tongue comprises a rounded edge.

### Claim 4 (depends on 1)

The hydroseeder of claim 1, wherein the water inlet is configured to spread the water as it enters the riser to provide a water curtain that extends both laterally and longitudinally across the infeed chute.

### Claim 5 (depends on 1)

The hydroseeder of claim 1, wherein the infeed chute comprises a water pipe configured to be fluidly coupled to a water source.

### Claim 6 (depends on 5)

The hydroseeder of claim 5, wherein:
The water inlet comprises a water spreading unit, the water spreading unit comprising:
a water spreading housing coupled to the water inlet of the sidewall of the riser; and
a tongue coupled to the water spreading housing and extending the water inlet of the riser; and
an output end of the water pipe is positioned above and spaced from the water spreading housing in a vertical direction.

### Claim 7 (depends on 6)

The hydroseeder of claim 6, wherein the output end of the water pipe comprises an angled opening relative to a horizontal axis.
